Summary of the invention
In view of this, the present invention proposes a kind of method for writing Web engineering test use-case, make writing of the test case of Web engineering simple, abstract, easily understand.
For achieving the above object, technical scheme of the present invention is achieved in that a kind of method for writing Web engineering test use-case, comprises step as follows:
Step one: Web engineering test use-case is according to specific language compilation, and described language-specific comprises macro instruction, test instruction, process;
Described macro instruction is used for setting during the self-defined testing results of author;
Whether described test instruction is working properly for testing Web engineering characteristic;
Described process is the set of a series of test instruction;
Step 2: by the grammer of language-specific described in analyzer analyzing step one, and be abstract syntax tree by the test case conversion of step one;
Step 3: by resolver, carrys out testing results use-case based on the abstract syntax tree of parser generation in step 2.
Further, described in step one, the process of language-specific comprises main procedure and subprocess, and main procedure is the entrance of all test instructions, and subprocess is the branching process that main procedure enters.
Further, described in step one, language-specific also comprises control statement, and described control statement is used for performing instruction according to decision condition.
Further, described in step one, language-specific also comprises variable, and described variable is used for reusing inside the action scope of its definition.
Further, analyzer described in step 2 analyzes the grammer of language-specific based on the pattern of recursive descent parsing.
Further, described analyzer is write based on JavaScript language.
Further, resolver described in step 3 performs the instruction in syntax tree successively based on the model of state machine.
Further, described resolver is write based on JavaScript language.
A kind of programming language, applies the method that above-mentioned any one writes Web engineering test use-case.
Relative to prior art, method for writing Web engineering test use-case of the present invention, makes the test case of writing web engineering simpler, more abstract and easily understand, the method designs for writing test case specially, thus ratio other Languages to write test case more convenient.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
The present invention is described in detail below in conjunction with embodiment.
According to method design Lemoncase language of the present invention.
Lemoncase language is to make the test case of writing web engineering simpler, more abstract and easily understand.This just similar Unreal in order to allow, to write game scripts simpler and more easily understand and invented the special game scripts that Unreal engine can run.
This language has 3 large ingredients:
1. macro instruction: author can self-defined testing results time some setting.
2. test instruction: test instruction is used to test certain characteristic of website/web application conditional statement whether working properly.
3. process: process is the set of a series of test instruction.Process is divided into main procedure and subprocess.Main procedure is exactly the entrance of all test instructions.Subprocess is exactly some branching processes that main procedure may enter.
● grammer
The most basic HelloWorld program is as follows:
Wherein, Processmain represents main procedure."; The result of instruction is record a word in test report.
1. macro instruction
#setMAX_LOOP50
This macro instruction can set main procedure and to rerun how many times.
2. test instruction
wait3000；
click“.btn”；
assert“#login”in10000askey1；
3 general being meant to of instruction above, wait for 3000 milliseconds, and clicking a class is the button of btn, assert to there will be the html element that an id is login in 10000 seconds, and under related data is recorded in this key word of key1.
About assert instruction: the expect in assert and jasmine in this similar node.js, assert whether some html elements meet specific condition.Assert parameter below asserts condition, and acquiescence is a css selector switch, and resolver can be attempted to judge whether the page there is the html element meeting this css selector switch.Can also in addition, assert that the set of the element meeting css selector switch exists? whether the element meeting css selector switch visible on the page? etc..Asserting there is individual optional parameter after condition, occur with the form of in (numeral), it is the time of asserting, if do not have this parameter, program can judge condition at once.When there being parameter, program can wait for certain hour, until meet decision condition or time-out failure.This parameter is very useful when the page has ajax request or page jump.After assertion time, also have another parameter, this parameter is a character string, and effect is below this key word, record the details of the time needed for asserting specifically successfully or time-out error.
3. subprocess
Sub-process name adds that namely a pair bracket represent and calls subprocess at this place of program.
4. control statement
if(n>2)click“.btnG”；
elsereturn；
Decision condition is connect, the instruction performed when be decision condition after then being true, the instruction that else is then condition to be performed when being false after If.
loop100
doclick“#refresh”；
while(“div>.close”){
click“div>.close”；
}
Loop digitized representation cycle index is below the instruction needing in circulation to perform after do.
Be decision condition after while, as long as decision condition is true, do instruction below will be performed.
5. variable
$selector＝“input#login”；
inputselectorby“admin”；
$ symbology defines a variable, the same with most of programming language, and variable can be reused inside the action scope of its definition.
● analyzer
The syntax analyzer that Lemoncase language has JavaScript language to write at present.Analyzer is the grammer analyzing Lemoncase based on the pattern of the recursive descent parsing (Recursivedescentparser) of classics, and the Program transformation that user is write be JavaScript can abstract syntax tree (AST).
● resolver
The resolver of Lemoncase is also based on JavaScript.Resolver carrys out testing results use-case based on the abstract syntax tree of parser generation.This resolver is the instruction performed successively based on the model of state machine in syntax tree.
The present invention designs for writing test case specially, thus ratio other Languages to write test case more convenient.
Suppose to use the interface of the webdriverJS of Selenium2 to write test case:
If write with Lemoncase, then can be such:
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
