Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
The test tools in the prior art are generally designed for ramp up, running and tear down, the scene is simple and single, and flexible self-defined configuration cannot be realized. It is inconvenient to fully simulate the jitter of the request, the irregular variation of the traffic.
Based on this, the embodiment of the invention provides a performance testing method based on a token bucket.
Fig. 2 is a schematic flow chart of a performance testing method based on a token bucket according to an embodiment of the present invention, and referring to fig. 2, a token bucket applied in the method according to the embodiment of the present invention generates a request token according to a preset generation rate; discarding the newly generated request token when the number of request tokens in the token bucket exceeds a capacity threshold of the token bucket may include the steps of:
and S21, acquiring the request information based on the preset interface.
S22, obtaining the request token in the token bucket, matching the request token with the request information, obtaining the request information with the request token, so that the request information with the request token is passed.
And S23, when the number of the request tokens in the token bucket is zero, stopping producing the request information with the tokens.
For example, in this embodiment, a token bucket may be used as the token bucket in the embodiment of the present invention to describe the technical solution of the present application. The principle can be seen as a container for storing tokens, and a capacity threshold is set. And placing tokens into the bucket at a set speed, and overflowing redundant tokens when the bucket is full of tokens. After the transmitted request enters, only the request token is obtained, the request token can be transmitted, and all the other requests which do not obtain the request token are discarded, so that the current limitation is achieved.
In some embodiments, optionally, the method further includes: receiving a setting instruction; and setting a capacity threshold value of the token bucket according to the setting instruction.
For example, in this embodiment, the size of the token bucket may be set according to the requirement, that is, the capacity threshold of the token bucket may be set, and the control of the traffic may be implemented by setting the capacity threshold of the token bucket.
Optionally, the method further includes: receiving a speed setting instruction; and setting a preset generation rate of the token bucket for generating the tokens according to the rate setting instruction.
For example, in this embodiment, the preset generation rate of the tokens in the token bucket may be set according to requirements, and the control of the traffic may be implemented by setting and controlling the preset generation rate of the tokens in the token bucket.
Optionally, before obtaining the request information based on the preset interface, the method further includes: receiving an interface setting instruction; and setting a preset interface according to the interface setting instruction.
For example, in this embodiment, flow control is not implemented in the service layer, which requires modification of logic of different service interfaces, and thus is costly. Flow control may be placed at the producer of a performance testing flow tool, for example, by passing the flow control policy logic of the token bucket before sending a request in the meter, requiring some secondary development of the performance tool. And can set speed and capacity thresholds for different interfaces through a specific Interface (API) or configuration. The control of the flow may be specific to a particular system. For example, the traffic set interface parameters are the rate of the token bucket, capacity threshold, targeted system appid (App and Id), API for throttling, time point, etc. And the flow can be controlled by carrying out indifferent flow limitation on all interfaces of the system without specifying an API.
In this embodiment, the token generation speed is controllable, and the bucket size is controllable, so that the token generation speed rate and the bucket size capacity can be continuously adjusted to control the traffic, and support variable QPS control. At present, various programming languages have corresponding token buckets, and a more flexible and real-time flow control simulation performance test is formulated by combining a pressure test tool for testing. For example, many current limiting tools such as ratelimit of Guava, jujuju/ratelimit of golang, etc. can be combined to conveniently implement the current limiting function. In the embodiment, the configuration and calling API can be used to adjust the flow of different interfaces, simulate the trend change of real requests, flow jitter, irregular flow change and the like.
The performance test method based on the token bucket provided by the embodiment of the invention utilizes the token bucket, wherein the token bucket generates the request token according to the preset generation rate; when the number of request tokens in the token bucket exceeds a capacity threshold of the token bucket, the newly generated request tokens are discarded. The method comprises the steps of acquiring request information based on a preset interface; obtaining a request token in a token bucket, matching the request token with request information, and obtaining the request information with the request token so that the request information with the request token is transmitted; when the number of request tokens in the token bucket is zero, the production of request information with tokens is stopped, e.g., requests without request tokens are discarded. The capacity threshold value of the token bucket can be adjusted, and the interfaces can be adjusted, so that different flow control strategies are set at different time points according to different interfaces to simulate the fluctuation of the requested flow in a real environment, and the method is more flexible and real-time. The invention can customize the flow strategy as desired and can make a complex flow by combining the token bucket flow limiting strategy with the pressure measuring tool. The robustness, performance and the like of the tested system are checked by simulating the jitter.
