How to Test Role-Specific Security with @WebMvcTest and @WithMockUser in Spring MVC

When developing web applications, securing REST endpoints based on user roles is crucial. This ensures that only authorized users can perform certain actions. However, testing these security configurations can sometimes be challenging. If you've found yourself wondering how to effectively test annotation-based role-specific security when using Spring’s @WebMvcTest and @WithMockUser, you’re not alone.

The Challenge

Imagine you have a REST controller that uses annotations to dictate that only users with a specific role can access certain endpoints. For example, you might have a controller like this:

In your tests, you're using @WebMvcTest together with @WithMockUser to simulate user authentication. Yet, the role specifications don't seem to affect the outcome of your tests. Regardless of what roles you define, your test always passes when using @WithMockUser.

The key issue is that the role checks provided by @Secured annotations don't appear to be recognized in your test configurations, so let's dig into the solution.

The Solution

To ensure that the @Secured annotations are recognized by your Spring application in tests, you need to enable global method security in your configuration, as follows:

Step 1: Enable Method Security

In your configuration class, add the @EnableGlobalMethodSecurity annotation with the securedEnabled property set to true. Here’s an example:

Step 2: Update Your Test Configuration

Make sure that your test configuration imports the necessary classes. Here is an example of how your test class should look after applying the updates.

Step 3: Run Your Tests

Now, you should see that your tests accurately reflect the security roles assigned. An authorized user with the right role can access the endpoints, while users without the appropriate roles get a 403 Forbidden status.

Conclusion

Testing role-specific security in Spring MVC can initially appear daunting, but by properly configuring your test classes and enabling method-level security annotations, you can ensure that your REST controllers are secure as intended. Don’t forget to check your configurations while writing tests; sometimes, a simple setup step can unlock the full functionality of your security context.

By following these guidelines, you can have confidence that your application is protected and behaves as expected concerning user roles. Happy coding!
