Integration test stages in Jenkins - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of an integration test stage in Jenkins pipelines?

The integration test stage checks if different parts of the software work together correctly after being combined. It helps find issues that unit tests might miss.

Name a common step included in an integration test stage.

Running automated test scripts that simulate real user scenarios or interactions between components.

How do you define an integration test stage in a Jenkins Declarative Pipeline?

You add a stage block named 'Integration Test' inside the pipeline with steps to run the integration tests, for example:<br>

stage('Integration Test') {
  steps {
    sh 'run-integration-tests.sh'
  }
}

Why is it important to run integration tests after unit tests in a CI/CD pipeline?

Unit tests check small parts individually, while integration tests check if those parts work well together. Running integration tests after unit tests ensures the combined system behaves correctly.

beginner

What happens if integration tests fail in a Jenkins pipeline stage?

The pipeline stage fails, stopping the process. This alerts developers to fix issues before moving to later stages like deployment.

What is the main goal of the integration test stage in Jenkins?

A To write new code features

B To deploy the application to production

C To check if combined software parts work together correctly

D To clean up old build files

Integration tests verify that different parts of the software function together as expected.

Where do you place the integration test stage in a Jenkins Declarative Pipeline?

A Inside the stages block

B Outside the pipeline block

C Inside the environment block

D Inside the post block

All stages, including integration test stages, go inside the stages block in a Declarative Pipeline.

What command might you use to run integration tests in a Jenkins pipeline step?

A echo 'Hello World'

B git clone

C docker build

D sh 'run-integration-tests.sh'

The shell command runs a script that executes integration tests.

If integration tests fail, what is the usual Jenkins pipeline behavior?

A Fail the pipeline and stop further stages

B Ignore the failure and continue

C Automatically fix the errors

D Restart the pipeline from the beginning

Failing tests cause the pipeline to stop to prevent deploying broken code.

Why run integration tests after unit tests?

A To deploy code faster

B To ensure individual parts work before testing them together

C Because integration tests are faster

D To save time by skipping unit tests

Unit tests check parts alone; integration tests check combined parts, so order matters.

Explain the role and typical steps of an integration test stage in a Jenkins pipeline.

Think about how Jenkins stages run commands to check software parts working together.

Describe what happens in a Jenkins pipeline when integration tests fail and why this is important.

Consider the safety checks in continuous integration.
