如何在模拟存储库中使用MockMvc？

Question

Conext

• I found this question here but my problem is different.

• So we are using Katharsis Controller and Spring Data Rest .

• We only have 1 controller for entire application and then the request will be sent to Spring Data Rest repositories classes.

• We want to use Spring Restdoc to generate documentation which requires us to write unit tests with MockMvc .

• But when using Mockmvc , it starts up the container and will require datasources to be set up.

• If we use standaloneSetup() and pass the mocked repository class, then MockMvc won't load Katharsis Controller and therefore the request won't reach that repository.

• I understand that we can create an in-memory database but our project is big and the database needs a huge number of tables to be created we want to avoid that since these tests are for documentation purposes.

Question

Is there any way to achieve this and only mock the target repository class?

Note

By repository I mean CrudRepository interface in Spring DataRest .

1. As Andy Wilkinson suggested, you may consider creating unit test where you wire beans together by yourself and use MokMvc standalone setup.

2. If you want to create integration test and create Spring Context anyway, there is way to fake Spring bean by using @Primary , @ActiveProfiles and @Profile annotations. I wrote a blog post with GitHub example how to do it . You just need to combine this approach with WebApplicationContext based MockMvc setup. It works without problems, I wrote such tests in the past.
