Summary

  • Adds a new recipe ThenThrowCheckedExceptionToRuntimeException that replaces checked exception class literals in thenThrow() calls with RuntimeException.class when the mocked method does not declare the exception in its throws clause
  • Wires the recipe into Mockito1to3Migration (which chains into 1to4 and 1to5)
  • Handles import cleanup for replaced exception types via maybeRemoveImport

Context: In Mockito 3+, thenThrow() validates that checked exceptions are declared in the mocked method's throws clause. Code like when(mock.method()).thenThrow(Exception.class) that worked in Mockito 1.x fails at runtime with MockitoException: Checked exception is invalid for this method! after migration.

Mockito 3+ validates that checked exceptions passed to `thenThrow()`
are declared in the mocked method's `throws` clause. This recipe
replaces undeclared checked exception class literals with
`RuntimeException.class` and cleans up unused imports.

- Replace manual method name/type checks with MethodMatcher
- Use ListUtils.map instead of boolean changed + manual loop
- Inline local variables and combine nested conditionals

…ationTest

The inline stub classes didn't extend Runner, causing compilation
errors on CI. The real PowerMockRunner is already on the classpath
via classpathFromResources, so the stubs are unnecessary.
