Configuration error: found multiple declarations of @bootstrapwith for test class

by

This error message usually occurs when there are multiple declarations of the same @bootstrapwith configuration for a test class. The @bootstrapwith configuration is used to specify the Bootstrap class that should be used to run the test class. Having multiple declarations can lead to conflicts and result in unexpected behavior.

To fix this error, you need to ensure that there is only one @bootstrapwith declaration for each test class. This can be done by removing any duplicate declarations or by refactoring the code to eliminate the need for multiple declarations.

Here’s an example to illustrate the issue: 

@Test
@bootstrapwith(MyBootstrap.class)
public class MyTestClass {
  // ...
}

// ...

@Test
@bootstrapwith(OtherBootstrap.class) // duplicate declaration
public class DuplicateTestClass {
  // ...
}

In the example above, the DuplicateTestClass has a duplicate @bootstrapwith declaration, which causes the configuration error. To fix this, you can simply remove the duplicate declaration: 

@Test
@bootstrapwith(MyBootstrap.class)
public class MyTestClass {
  // ...
}

// ...

@Test
public class DuplicateTestClass {
  // ...
}
