List of articles
brief introduction
When performing integration tests on modules , Hope to be able to input URL Yes Controller To test , If by starting the server , establish http client To test , This can make testing very cumbersome , such as , Slow startup speed , It's not convenient to test and verify , Rely on network environment, etc
MockMvc Realized with Http Simulation requested , Can use the form of network directly , The switch to Controller Call to , This makes the test faster 、 Independent of network environment , It also provides a set of verification tools , This makes the verification of the request uniform and convenient
technological process
- MockMvcBuilder Instantiation MockMvc
- mockMvc call perform, Execute one RequestBuilder request , call controller Business processing logic
- perform return ResultActions, Return operation result , adopt ResultActions, Provides a unified way to verify
- Use StatusResultMatchers Verify request results
- Use ContentResultMatchers Verify the content returned by the request
Code
Here is the complete test case ： contain Junit5 as well as Mockmvc
