I am trying to unit test a webapp that I am developing in Maven/Eclipse.

  • 0

I am trying to unit test a webapp that I am developing in Maven/Eclipse. It is a Spring MVC webapp, and I need some unit tests to test my model controller.

To do this, I need to use my webapp config .xml files to inject the controller, however, all my configuration (and other associated files that the configs reference) are in the src/main/webapp directory (as per Maven convention) – there are a lot of files in here that i need to reference in my tests, but they are not available when running the test as they are not on the classpath (Maven only seems to be adding src/main/java, src/test/java, src/main/resources, src/test/resources to the classpath but not src/main/webapps)

I do not want to have to copy my entire webapp in to my src/test/resources folder just for the purpose of testing – is there any other way to be able to access them?

I can get around this by changing the Eclipse “Run Configurations” to include this folder on the classpath, but that will not work when running the tests from the command line?

Has anyone else encountered this? is there a know solution?

Thanks!

    In general, you should be using mocks (e.g., EasyMock or jMock) to handle unit testing for your controller; a unit test should test a component in isolation from the rest of the system.
    In Spring 3, you can define your Controllers as a POJO with annotations and then simply test the Controllers without any interaction from Spring at all.

    If you wish to do more integration-level testing, then you can place common parts of config files in src/main/resources so they become accessible in the classpath. Then use a test specific configuration in src/test/resources for your test. That file can either import those files along with anything you need, or you can annotate your test case with @ContextConfiguration to specify the multiple files that are needed to assemble the context.

    For a concrete example, see this blog post on integration testing Spring MVC. The Testing chapter of the Spring manual also has a decent overview of integration testing in Spring.
