Nx comes with dedicated documentation for each framework:

affected:test

Test projects affected by changes

Usage

nx affected:test

Install nx globally to invoke the command directly using nx, or use npx nx, yarn nx, or pnpx nx.

Examples

Run tests in parallel:

nx affected:test --parallel=5

Run the test target for all projects:

nx affected:test --all

Run tests for all the projects affected by changing the index.ts file:

nx affected:test --files=libs/mylib/src/index.ts

Run tests for all the projects affected by the changes between main and HEAD (e.g., PR):
