Jest Run It - Run and debug individual Jest tests from VS Code

While writing tests in Jest have you ever wanted to run a single test that you changed, but have to fiddle with Jest CLI arguments so that Jest can run only that test. I know, I have been there and it is painful.

Wouldn't it be nice if you could choose what test(s) to run right from your editor/IDE. And apparently IntelliJ family of IDEs had this feature for ages. I get so jealous when I pair with my co-worker who uses IntelliJ and they run/debug a test with the click of a button. My favorite IDE of the world, VS Code, couldn't do it. So I decided to find a solution and it resulted in me writing this VS Code plugin.

Apart from able to run/debug individual tests it has few other tricks under the sleeve as well:

  2. Editor title actions to run/debug tests Alt Text

One extremely powerful typescript feature is automatic type narrowing based on control flow. This means a variable has two types associated with it at any specific point of code location: a declaration type and a narrowed type.

#3 Use discriminated union instead of optional fields
