  1. Rebuild all the packages via `make packages-build` or…
  2. Rebuild only a specific package, for example `make package-build-bar` for `@nivo/bar` package
 
+### Testing
+
+To run unit tests on all packages, run the following command:
+
+```
+make packages-test
+```
+
+If you only made modifications on a specific package,
+you can use the scoped form to speed up the process:
+
+```
+make package-test-bar
+```
+
+where `bar` is the name of the targeted nivo package.

 ### Formatting
 
 Nivo uses prettier in order to provide a consistent code style.
