Provide JUnit5 extension for integration tests as a replacement for old junit4 rule

[de-jcup]

Situation

Currently we have for integration tests only a Junit4 way:

import org.junit.*;

public class XyzScenario1Test {

    @Rule
    public IntegrationTestSetup setup = IntegrationTestSetup.forScenario(Scenario12.class);

    @Test
    public void integrationTestXyz(){
        // ... the integration test
    }
}

Wanted

We want to provide Junit5 way

Solution

We will provide a Junit5 extension called IntegrationTestExtension.
To provide test scenario parameters we introduce: @WithTestScenario

Here an example how it will look like when using Junit5:

import org.junit.jupiter.api.Test;

@ExtendWith(IntegrationTestExtension.class)
@WithTestScenario(Scenario1.class)
class XyzScenario1IntTest {

     @Test
     void integrationTestXyz(){
        // ... as usual
     }
}
