 More details about version upgrades can be found in the [CHANGELOG](CHANGELOG.md).
 
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](http://getcomposer.org).
+Because the test suite contains some circular dependencies, you may have to
+manually specify the root package version like this:
+
+```bash
+$ COMPOSER_ROOT_VERSION=`git describe --abbrev=0` composer install
+```
+
+To run the test suite, you need PHPUnit. Go to the project root and run:
+
+```bash
+$ phpunit
+```
