Class ParameterizedTestExtension

java.lang.Object

org.operaton.bpm.engine.test.junit5.ParameterizedTestExtension

All Implemented Interfaces:

org.junit.jupiter.api.extension.Extension, org.junit.jupiter.api.extension.TestTemplateInvocationContextProvider

public class ParameterizedTestExtension
extends Object
implements org.junit.jupiter.api.extension.TestTemplateInvocationContextProvider

This JUnit 5 extension is intended to make the conversion from JUnit 4 Tests like ContainerAuthenticationFilterTest as easy as possible. The issue is, that these tests are run with @RunWith(org.junit.runners.Parameterized.class) and use a static method annotated with @org.junit.runners.Parameterized.Parameters to inject parameters into the constructor of the test class or by using field injection with @Paramater(0), @Parameter(1). This extension implements the same mechanism for JUnit 5. To migrate the tests you can follow the following recipe:

1. Remove the junit 4 imports

    import org.junit.After;
    import org.junit.Assert;
    import org.junit.Before;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.junit.runners.Parameterized;
    import org.junit.runners.Parameterized.Parameters;
    

2. Add the imports for junit 5 and this class

    import org.junit.jupiter.api.*;
    import org.operaton.bpm.engine.test.junit5.ParameterizedTestExtension.Parameterized;
    import org.operaton.bpm.engine.test.junit5.ParameterizedTestExtension.Parameters;
    import org.operaton.bpm.engine.test.junit5.ParameterizedTestExtension.Parameter;
    

3. Replace the class @RunWith(Parameterized.class) annotation with @Parameterized
4. Replace @Before with @BeforeEach and @After with @AfterEach
5. Replace each @Test with @TestTemplate
6. Use assertion methods from Assertions instead from Assert
