In order for your changes to be accepted, you need to pass all the CI tests. This implies:

  • Your code compiles;
  • Your code passes Prettier and ESLint;
  • Your code passes existing tests and new tests.

You are encouraged to test your changes locally instead of waiting on CI results. You must write unit tests for your added pure functions whenever possible.

You can also test your changes on tssa itself. For example, you can create a test branch test123, do some changes in test123 and commit. Then you can run git diff master test123 | yarn start ., which will give you the diff analysis result on your change in test123. Remember that you need to run yarn build before yarn start to ensure that you are always using the latest compiled code!

What's even more important is that you test your changes against real complex monorepos. To do that, you need to run yarn bundle to produce a self-contained index.js inside bin. Then you can copy index.js into the root of the monorepo, and run the test by git diff master test123 | node index.js monorepo-package-1 monorepo-package-2 .... Note that the root of the monorepo must has typescript as either devDependency or dependency, since the bundled index.js doesn't bundle TypeScript.
