Tips for Testing

Writing tests

• Build-in quality checking for both style and security
• Testers should work with Devs
• Testers are not replaceable, they know how users work
• Testers should constantly explore and learn new skills.

For Automated Tests in CI/CD

Running

• Don't run all tests parallely - longer UI tests could be failing due to failing unit tests
• So run all unit tests in parallel, then switch to service tests, and then UI tests
• Think of writing tests as an investment in the future
• "Writing tests is kind of an art" - settle for 80% coverage, not 100%

Ideas for running tests

• Run conditional stage testing - test only if a certain component was modified
• Stop all running jobs when one test has failed - in parallel situations
• Auto-cancel queued builds - in case a developer made a quick change just after pushing once
