Take a look at this video I published earlier this year about testing Web APIs using Node.js.
This video is a walk-through of the Jasmine test suite written for one of our recently open-sourced projects, MoneyLog.
Our Jasmine API test suite allows us to work on new API features, and fixes, quickly and confidently. The test suite is also an integral part of our CI/CD pipeline.
Every change we make, the test suite helps us to ensure our changes work as expected, and that the rest of the API functionality is unaffected.
This is hopefully the first of many software development videos we publish.
