The structure of the groovy script in ngrinder is similar to junit, while encapsulating its own annotations on the basis of junit to control the execution of the script.
1. The running logic diagram is as follows:
Only the logic of the groovy script is listed here, and the jython script is similar and will not be covered separately here.
II. Comparison of the use of various notes
III. Focus
In ngrinder, using single-process multithreading is usually sufficient for most tests, so:
What we need to pay attention to most is @ Test, which is the body of the loop.
The second is @ Before, where shared variables for multiple loop bodies are set.
Next are @ BeforeThread and @ AfterThread, which are used to set the behavior of each thread before and after execution.
IV. Specific code structure
@ RunWith (GrinderRunner) / / add this annotation to every test class
Class TestRunner {
@ BeforeProcess / / execute before each process starts
Public static void beforeProcess () {
/ / load resource files, initialize GTest, etc.
}
@ BeforeThread / / execute before each thread executes
Public void beforeThread () {
/ / Log in, set cookie and so on
}
@ Before / / execute before each @ Test annotated method is executed
Public void before () {
/ / set variables, logic shared by multiple @ Test methods, etc.
}
@ Test / / keep running until the test ends. The methods of each @ Test annotation are executed asynchronously.
Public void foo () {
/ /...
}
@ Test
Public void bar () {
/ /...
}
@ After / / execute after each @ Test annotated method is executed
Public void after () {
/ / rarely used
}
@ AfterThread
Public void afterThread () {
/ / logging out and so on
}
@ AfterProcess / / execute after the end of each process
Public static void afterProcess () {
/ / close resources
}
