Before working on a big change on Vest’s codebase, it is a good idea to first discuss the change in an issue to make sure it fits the project’s goals and future plans.
This project uses yarn. When working on this project you should first clone it locally, install its dependencies and run the tests (vx test) to make sure everything works. You should regularly run the tests during development to make sure they still pass and no functionality has been affected by your changes.
Vest’s functionality is fully documented and fully tested. Please make sure to update the documentation and tests when making a functional change.
The code in this repo is written with typescript and complied to javascript on build.
Source files are globally and uniquely named in the repo, meaning that there cannot be two files with the same name in the repo. Files are imported using their unique name and that's it. no need for relative path.
import name from 'fileName'
When you add new files, they need to be added to the list of files so the aliasing works. You can run yarn dev while developing to continuously update the list of files upon change.
To test your changes, you need to create a test file inside a __tests__ directory. Tests files are only looked for there.
The naming convention for a test file is moduleName.test.ts.
To run tests, you need to run vx test. This will run all tests in all packages. The tests are being run by jest.
You can narrow it down by specifying the package name:
vx test vest
Normal jest options can be passed to the test command.
vx test --watch
To build your changes, you need to run vx build. This will build all packages.
You can also run vx build -p <packageName> to build only one package.
This will generate all distribution files and type declarations.
