Package org.openrewrite.java.testing.junit5

Class ParameterizedRunnerToParameterized

  • public class ParameterizedRunnerToParameterized
extends org.openrewrite.Recipe
    Recipe for migrating JUnit4 @RunWith(Parameterized.class) tests to the JUnit 5 Jupiter ParameterizedTest equivalents.

    1. Remove `@RunWith(Parameterized.class)` 2. Replace `@Test` with `@ParameterizedTest` having arguments from `@Parameters` method 3. Add `@MethodSource(...)` with methodName argument equal to `@Parameters` method name to each `@ParameterizedTest` 4. For constructor injected tests change constructor to an initialization method having a void return type. 5. For field injected test generate and insert an init-method for class field values 6. Remove @Parameters and @Parameter annotations 7. Remove imports org.junit.Test; org.junit.runner.RunWith; org.junit.runners.Parameterized; org.junit.runners.Parameterized.Parameter; org.junit.runners.Parameterized.Parameters; 8. Add imports org.junit.jupiter.params.ParameterizedTest; org.junit.jupiter.params.provider.MethodSource;
