Debug Node.js Unit Tests
Explore how to effectively debug Node.js unit tests written with Jasmine. Learn to isolate tests using fit, utilize console logging for clarity, and leverage debugger tools in browsers and IDEs to inspect and resolve test issues in your JavaScript applications.
We'll cover the following...
Debugging our unit tests is very important. There are a few techniques for doing that.
Run a single test
Isolating a single test allows us to focus on it and make sure the issue we are debugging is indeed caused by this test. Jasmine provides the fit capability for focusing on a single test and only running it, skipping all the rest.
fit('this is the only test that will run', () => {...})
It works for multiple instances of fit too. See the example below.
fit('this is the only test that will run', () => {...})
fit('this is the only other test that will run', () => {...})
Using the console.log
The console.log (and its sibling methods info, table, …) allows us to log out states and markers at various stages of the ...
