Failing builds on test failures in Jenkins - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does it mean when a Jenkins build fails on test failures?

It means Jenkins stops the build process and marks it as failed if any automated test does not pass. This helps catch problems early.

beginner

How can you configure Jenkins to fail a build if tests fail?

You add a test step (like JUnit) in the Jenkins pipeline or job and set it to mark the build as failed if tests do not pass.

beginner

Why is failing builds on test failures important in DevOps?

It prevents broken code from moving forward, ensuring only tested and working code is deployed. This keeps software quality high.

What Jenkins plugin is commonly used to report test results and fail builds on test failures?

The JUnit plugin is commonly used to parse test reports and fail builds if tests fail.

beginner

What is the effect of ignoring test failures in Jenkins builds?

Ignoring test failures lets broken code pass, which can cause bugs in production and reduce software reliability.

What happens in Jenkins when a test fails and the build is set to fail on test failures?

A The build continues but logs a warning.

B The build stops and is marked as failed.

C The build ignores the failure and passes.

D The build restarts automatically.

When Jenkins is configured to fail on test failures, any failed test causes the build to stop and be marked as failed.

Which Jenkins plugin helps to mark builds as failed based on test results?

A JUnit plugin

B Git plugin

C Docker plugin

D Slack plugin

The JUnit plugin parses test reports and can fail builds if tests fail.

Why should builds fail on test failures in a CI/CD pipeline?

A To allow manual testing later

B To speed up the build process

C To prevent broken code from deploying

D To ignore minor errors

Failing builds on test failures stops broken code from moving forward, ensuring quality.

How do you tell Jenkins to fail a build on test failures in a pipeline script?

A Use the 'junit' step with 'allowEmptyResults: false'

B Use 'echo' command

C Use 'sh' step without test commands

D Use 'archiveArtifacts' step

The 'junit' step processes test results and fails the build if tests fail.

What is a risk of not failing builds on test failures?

A Builds run faster

B Build logs get smaller

C Tests run twice

D Broken code may reach production

Ignoring test failures risks deploying broken or buggy code.
