@WebMvcTest ignores base path configured via @WebAppConfiguration

[lorenzodee]

Set resource base path to make @WebMvcTest behave the same as @WebAppConfiguration and @SpringBootTest

This fixes issue #16484 .

Upon further investigation, when running tests that use @WebAppConfiguration or @SpringBootTest, the resourceBasePath (in WebMergedContextConfiguration) was being set to src/main/webapp for servlet-based environments. But when using @WebMvcTest, the resourceBasePath was being set to "" (empty string). This causes the difference in behavior.

In the sample tests in #16484 , the empty string resourceBasePath causes the resource to be missing, since it was not looking under src/main/webapp.

Thanks, I'm tempted to look at extracting a method in SpringBootTestContextBootstrapper so we can share that identical logic. We should ideally also try to add a test for this.

Thanks Phil. I'd like to help, if I may. Would it be proper to add a test in WebMvcTestAutoConfigurationIntegrationTests that would check for a resource under src/main/webapp?

Ended up adding tests in separate test classes. Similar to what was done in SpringBootMockServletContextTests. Hope this helps.
