Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the disclosure, but it will be appreciated by those skilled in the art that the disclosure may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the embodiments.

Fig. 1 is a schematic flow chart of an automated printing test method according to an exemplary embodiment of the disclosure, as shown in fig. 1, the method includes:

step S101, calling a tested printing program interface, reading printing test data in a basic database to obtain printing result data, wherein the basic database is used for storing the printing test data and is established in advance;

step S102, comparing the value of a first field with the value of a second field, wherein the first field is the field in the printing result data, the second field is the field in the basic database,

and the first field corresponds to the second field;

step S103, judging whether the value of the first field is different from the value of the second field;

and step S104, if the value of the first field is different from the value of the second field, recording the first field.

The printing test is mainly to examine whether the printing program interface under test is normal. There is a case where a printing program runs: the printing test data has two fields with different attributes, but the values of the two fields are exactly the same under certain conditions, for example, a 'total price of goods' field and a 'unit price of goods' field, the value is the same when one product is used, but the values are different when a plurality of products are used, when the printing program interface reads the printing data, the value of an error field is read, for example, the value of the 'unit price of goods' field is read at the position of the 'total price of goods' field, because the values of the two fields are the same when one product is used, the printed result picture and the reference picture are still the same and can not reflect errors, and whether the printing program interface reads the data is wrong or not is checked.

Before printing test, according to the test purpose, preparing different types of printing test documents, extracting the common data of the printing test documents as basic data, and storing the basic data into a basic database. And during printing test, calling a tested printing program interface, reading the printing test data in the basic database, and obtaining printing result data. In one embodiment, the read printing test data is directly used as printing result data, that is, the data returned by the printing program interface is directly used as the printing result data; in another embodiment, the printing result picture is obtained by printing according to the printing test data, and then the printing result data is extracted according to the printing result picture, that is, the printing test data in the basic database is read and is used as the input of the tested printing program for printing, the printing is virtual printing, for example, the ADOBE virtual printing technology is used for printing, so that the printing result picture is obtained and stored, the printing result picture can be in pdf format or can be converted into other picture formats such as jpg, the printing result data of the printing result picture is extracted and is printed by the ADOBE virtual printing technology, so that the printing result picture is obtained, and then the printing result picture is converted into data file formats such as TXT format, so that the printing result data is obtained. In the latter embodiment, the print result data is extracted after the print result picture is obtained, and although there are more links than in the former embodiment, the print result data can reflect the actual print result more directly.

After the printing result data is obtained, if the format of the printing result data is the same as that of the data in the basic database, the format conversion of the printing result data is not needed, and if the format of the printing result data is different from that of the data in the basic database, the format conversion of the printing result data is carried out. The format of the printing result data and the data in the basic database is usually in a jason format, and the data in the jason format can be converted into a jason object for comparison. And then comparing the value of the first field with the value of a second field corresponding to the first field by taking a field in the printing result data as the first field and taking a field in the standard template picture data as the second field, wherein the first field and the second field are corresponding to the same field name (or identification) of the first field and the second field.

And comparing the value of the first field with the value of the second field, judging whether the value of the first field is different from the value of the second field, and recording the first field if the value of the first field is different from the value of the second field. And finally, the recorded first field is used as a data checking result, so that a user can know which fields are read by the back-end interface of the printing program and have errors in values. And if the value of the first field is the same as the value of the second field, the data read by the back-end interface of the printing program is correct, and no problem exists.

Fig. 2 is a schematic flow chart illustrating another automated print testing method according to an exemplary embodiment of the disclosure, as shown in fig. 2, the method includes:

step S201, calling a tested printing program interface, reading printing test data in a basic database to obtain printing result data, wherein the basic database is used for storing the printing test data and is established in advance;

step S202, comparing a value of a first field with a value of a second field, wherein the first field is a field in the printing result data, the second field is a field in the basic database, and the first field corresponds to the second field;

step S203, judging whether the value of the first field is different from the value of the second field;

step S204, if the value of the first field is different from the value of the second field, recording the first field.

Wherein steps S201 to S204 are the same as steps S101 to S104, respectively.

Step S205, according to the printing test data in the basic database, acquiring a corresponding standard template picture from a standard template picture library, wherein the standard template picture in the standard template picture library is generated according to the data in the basic database, and the standard template picture corresponds to the data in the basic database.

And step S206, printing to obtain a printing result picture according to the printing test data. And printing the printing test data as the input of the tested printing program, wherein the printing is virtual printing, for example, the printing is performed by using an ADOBE virtual printing technology, and a printing result picture is obtained and stored.

The sequence of step S205 and step S206 may be exchanged, or a print result picture may be obtained by printing according to the print test data, and then a corresponding standard template picture may be obtained from a standard template picture library according to the print test data in the basic database.

And the standard template picture is made according to the data in the basic database, corresponds to the data in the basic database and is stored in the standard template picture library. Each standard template picture in the standard template picture library has a unique identifier, the identifier can be a character string of 'document type + template name', and the document type is a document type corresponding to the template. And during testing, finding the corresponding standard template picture in a standard template picture library according to the printing test data. The standard template picture and the print result picture can be in pdf format, and can also be converted into other picture formats such as jpg.

And step S207, determining the test range of the standard template picture according to the test range of the printing result picture.

The test range of the print result picture is determined by a tester in advance, and can be the whole print result picture, or the range of the print result picture without white edges, or a local area of the print result picture defined according to test requirements, for example, the print result picture is an express document, and only a LOGO (LOGO) area and a bar code area of the document are used as the test range. The test range of the print result picture is expressed using a pixel coordinate matrix or a pixel coordinate function. All vertex pixel coordinates of the boundary of the test range including at least the print result picture in the pixel coordinate matrix representing the test range. For a rectangular test range, a pixel coordinate matrix may be constructed using the four vertex pixel coordinates of the rectangular test range boundary (i.e., the four corner pixel coordinates of the rectangular test range) to represent the test range, for example, test range M ═ 100,100 (100,1010); (1010,100) (1010 ) ], where (100 ) is the upper left vertex pixel coordinate, (100,1010) is the upper right vertex pixel coordinate, (1010,100) is the lower left vertex pixel coordinate, and (1010 ) is the lower right vertex pixel coordinate, and the determined boundary is the rectangle defined by the four pixel vertices. If the testing range is in an irregular shape, the boundary of the testing range is described by using a pixel coordinate function taking the vertex pixel coordinate as a characteristic point, and the shape of the testing range is different and the pixel coordinate function is also different. Compared with a rectangular test range, the boundary description of the irregular-shaped test range is complex, the irregular-shaped test range can be covered by the rectangular test range, and in addition, the conventional printing documents are all formed by rectangular areas, so the test range is preferably the rectangular test range with a simple description mode. It should be noted that the description of the test range can be regarded as the description of the boundary of the test range.

And the testing personnel predetermine the testing range of the printing result picture. The determining the test range of the standard template picture according to the test range of the print result picture based on the predetermined test range of the print result picture may include:

step a1, obtaining first boundary pixel points of the test range of the printing result picture, where the first boundary pixel points at least include all vertex pixel points of a first boundary, and the first boundary is the boundary of the test range of the printing result picture.

The first boundary pixel point may be obtained from description of a test range of the print result picture, such as a pixel point coordinate matrix or a pixel point coordinate function. The first boundary pixel points can be directly input into a test program through an input interface by a tester, and accordingly the test program obtains the first boundary pixel points from the input interface. The first boundary pixel points can also be stored in the database, and an identifier corresponding to the printing result picture is set, for example, the identifier includes a name of the printing result picture, and the test program reads the corresponding first boundary pixel points from the database according to the name of the printing result picture. The shape of the boundary of the test range is determined by the vertex of the boundary, so the vertex of the boundary is the characteristic point of the boundary, and for the first boundary, the first boundary pixel points at least comprise all the vertex pixel points of the first boundary. It should be noted that, if the boundary of the test range of the print result picture is circular, that is, the first boundary is circular, a plurality of points on the first boundary that are symmetrical with respect to the circle center, for example, four or six points that are symmetrical with respect to the circle center, may be used as vertex pixels of the first boundary, that is, as first boundary pixels, because the first boundary pixels and the second boundary pixels are used to compare to verify whether the mapping boundary of the standard template picture is correct, rather than using the first boundary pixels and the second boundary pixels to describe the boundary, the points that are partially featured on the first boundary and the second boundary are taken, the circular boundary has symmetry, and the plurality of points on which the circle center is symmetrical may be used to verify whether the mapping boundary of the circle is correct. For a circular boundary, the central point of the circular boundary and a plurality of symmetrical points on the circular boundary may also be combined to verify the circular mapping boundary, and the central point of the circular boundary may also be obtained from the pixel point function description of the test range.

Step a2, mapping the first boundary to the standard template picture to obtain a mapping boundary of the standard template picture.

The first boundary is mapped to the standard template picture, and the description of the boundary of the test range of the print result picture can be mapped to the description of the boundary of the standard template picture by using a preset mapping function, so that the mapping boundary is obtained. The mapping function may be a proportional function 1, that is, a description of the standard template picture using the same boundary of the test range as the print result picture, for example, the same pixel coordinate matrix description or the same pixel function description, specifically, for example, the description of the boundary of the test range of the print result picture is B1 ═ 100,100 (100,1010); (1010,100) (1010 ) ], the description of the boundary of the test range of the standard template picture, i.e. the description of the mapping boundary, is B2 ═ B1 × 1 ═ [ (100 ) (100,1010); (1010,100) (1010 ) ], where (100 ) is the boundary upper left vertex pixel coordinate, (100,1010) is the boundary upper right vertex pixel coordinate, (1010,100) is the boundary lower left vertex pixel coordinate, and (1010 ) is the boundary lower right vertex pixel coordinate, that is, the mapping boundary of the standard template picture is the rectangle determined by the four pixel vertices. The mapping function may also be set as a translation function according to the printing margin or the inherent error of the printer, for example, in order to facilitate binding, the printing margin is 100 pixels apart from the left, that is, the printing content integrally translates to the right by 100 pixels in the standard template picture compared to the printing result picture, or the inherent error of the printer may cause the printing content to integrally translate to the right by 100 pixels in the standard template picture compared to the printing result picture, and correspondingly, the mapping function is to translate 100 pixels to the left the pixel coordinate matrix or the pixel point function of the test range boundary of the printing result picture, so as to obtain the description of the test range boundary of the standard template picture, thereby obtaining the mapping boundary.

Mapping the first boundary to the standard template picture, and projecting the test range boundary of the printing result picture to the standard template picture by using an image processing program, namely converting pixel point coordinates in the description of the test range boundary of the printing result picture into pixel point coordinates in the standard template picture, so as to obtain the description of the mapping boundary, namely obtaining the mapping boundary.

Step a3, obtaining second boundary pixel points, where the second boundary pixel points at least include all vertex pixel points of the mapping boundary, the second boundary pixel points correspond to the first boundary pixel points, and the number of the second boundary pixel points is equal to the number of the first boundary pixel points.

After a mapping boundary of a test range of a standard template picture is obtained, second boundary pixel points corresponding to the first boundary pixel points are obtained, wherein the second boundary pixel points are pixel points on the mapping boundary and at least comprise all vertex pixel points of the mapping boundary. Obtaining the coordinates of the corresponding second boundary pixel points in the standard template picture according to the coordinates of the first boundary pixel points, so as to obtain the second boundary pixel points, specifically, if a mapping function is used for mapping the first boundary to the standard template picture, if the mapping function is 1, the coordinates of the second boundary pixel points are the same as the coordinates of the first boundary pixel points, and if the mapping function is a translation function, the coordinates of the first boundary pixel points are translated by the same translation amount to obtain the coordinates of the second boundary pixel points; and if the test range boundary of the printing result graph is projected into the standard template picture, transforming the coordinates of the second boundary pixel points by using a coordinate transformation mode during projection to obtain the coordinates of the first boundary pixel points. The coordinates of the second boundary pixel points are determined by the coordinates of the first boundary pixel points, and the coordinates are corresponding to each other and equal in number. Another method for obtaining second boundary pixel points is to traverse the pixel points of the standard template picture according to the number of the first boundary pixel points and a set arrangement sequence of the first boundary pixel points (for example, a rectangular test range boundary, clockwise arrangement from an upper left vertex to a lower left vertex), in the same sequence as the arrangement sequence of the first boundary pixel points, and extract the pixel points in the mapping boundary, which are the same as the characteristics (for example, vertex or symmetric point) of the first boundary pixel points, according to the description of the mapping boundary, to obtain the second boundary pixel points, but this method has lower precision compared with the aforementioned method.

A4, comparing the RGB value of the first boundary pixel point with the RGB value of the second boundary pixel point;

step a5, if the RGB values of the first boundary pixel point and the RGB values of the second boundary pixel point are all the same, determining that the test range of the standard template picture is successful, and taking the range within the mapping boundary as the test range of the standard template picture, otherwise, determining that the test range of the standard template picture is failed, and ending the printing test.

After the first boundary pixel point and the second boundary pixel point are obtained, comparing RGB values of the first boundary pixel point and the second boundary pixel point, if the RGB values of the first boundary pixel point and the second boundary pixel point are all the same, the second boundary pixel point and the first boundary pixel point are completely coincided, the obtained mapping boundary of the standard template picture is correct, namely the testing range of the standard template picture is determined to be successful, and the range within the mapping boundary is taken as the testing range of the standard template picture. If a pixel point with different RGB values exists between the second boundary pixel point and the first boundary pixel point, the second boundary pixel point is not matched with the first boundary pixel point, and the obtained mapping boundary of the standard template picture is wrong

That is, determining the test range of the standard template picture fails.

Step S208, if the testing range of the standard template picture is determined to be successful, traversing pixel points of the printing result picture within the testing range and pixel points of the standard template picture within the testing range, and comparing the RGB value of a first pixel point with the RGB value of a second pixel point, wherein the first pixel point is a pixel point of the printing result picture within the testing range, the second pixel point is a pixel point of the standard template picture within the testing range, and the second pixel point corresponds to the first pixel point;

step S209, determine whether the RGB values of the first pixel point and the second pixel point are different.

After the testing range of the standard template picture is determined to be successful, traversing pixel points of the printing result picture within the testing range and pixel points of the standard template picture within the testing range, taking the pixel points of the printing result picture within the testing range as first pixel points, taking the pixel points of the standard template picture within the testing range as second pixel points, comparing the RGB value of the first pixel points with the RGB value of the second pixel points, and judging whether the RGB value of the first pixel points is different from the RGB value of the second pixel points. In the method, since each pixel point in the test range is compared, the precision is high, but the workload is large, the time is consumed, and the resource occupation is large. The initial pixel point of each line of pixels in the test range of the printing result picture can be taken as a first pixel point, the initial pixel point of each line of pixels in the test range of the standard template picture can be taken as a second pixel point, the initial pixel points (namely the first pixel point and the second pixel point) of each line of pixels in the printing result picture and the marking template picture can be traversed in a row unit, and the RGB value of the first pixel point of each line and the RGB value of the second pixel point can be compared row by row.

Step S2010, if the RGB values of the first pixel point and the second pixel point are different, marking the first pixel point on the print result picture and/or marking the second pixel point on the standard template picture, and/or counting the number of the first pixel point.

If the RGB values of the first pixel point and the second pixel point are all the same, the printing result picture and the standard template picture are matched in the test range, and the printing program is normal. And if the comparison is positive, the RGB value of the first pixel point is different from the RGB value of the second pixel point, namely, a pixel point with different RGB values exists between the second pixel point and the first pixel point, and the printing result picture is not consistent with the standard template picture. In order to mark which parts in the printing result picture are different from the standard template picture, if the RGB value of the first pixel point is different from the RGB value of the second pixel point in the comparison, the first pixel point can be marked on the printing result picture, so that a user can conveniently check the positions, different from the standard template picture, in the printing result picture; the second pixel point can be marked on the standard template picture at the same time, so that a user can clearly check the difference between the printing result picture and the standard template picture; the second pixel point can also be marked on the standard template picture, so that the user needs to approximately find out which parts have problems on the printing result picture according to different positions on the standard template picture and the printing result picture. It should be noted that, since the mark is usually small, in order to make the mark visible, the mark is not only marked on the first pixel or the second pixel, but also can be a mark covering the first pixel or the second pixel.

FIG. 3 is a diagram illustrating an exemplary print test result flag. In fig. 3, taking an express document as an example, the left side is a standard template picture, the right side is a printing result picture, and an ellipse is used as a mark to mark a difference between the standard template picture and the printing result picture after the printing test, the first difference is that the printing result picture lacks an area name in the receiving address information, and the second difference is that the receiving payment does not have a decimal in the printing result picture. And printing the difference between the standard template picture and the printing result picture after the test, namely the second pixel point and the first pixel point with different RGB values.

Besides marking the pixels with different RGB values in the printing result picture and the standard template picture, the method can also count the first pixels with different RGB values in the printing result picture and the corresponding RGB values of the second pixels in the standard template picture, and a user can know how much difference exists between the printing result picture and the standard template picture through the counting condition of the first pixels. If the user only needs to know how much difference exists between the printing result picture and the standard template picture, the user does not mark the pixels with different RGB values in the printing result picture and the standard template picture, and only counts the first pixels with different RGB values in the printing result picture and the corresponding second pixels in the standard template picture.

The data verification is performed in the steps S201 to S204, the style verification is performed in the steps S205 to S2010, and whether the printing program itself is normal is checked by comparing the printing result picture with the standard template picture. It should be noted that, as a whole, steps S201 to S204 and steps S205 to S2010 may be executed in parallel or sequentially, and a sequential execution relationship between the two whole steps, that is, a sequential execution relationship between the data verification step and the pattern verification step, is represented by a dotted line in fig. 2 to indicate that the sequential execution relationship is not unique.

If the printing result picture has pixels with different RGB values within the testing range of the printing result picture and the pixels with different RGB values within the testing range of the standard template picture, the printing result picture is not matched with the standard template picture, the printing program has problems, the pixels which correspond to each other but have different RGB values can be marked on the printing result picture and/or the standard template picture, a user can conveniently and visually observe different places of the printing result picture and the standard template picture, the number of the pixels with different RGB values in the printing result picture and the standard template picture can be counted, and the user can conveniently know how much different the printing result picture and the standard template picture.
