+## Running tests
+
+To run the tests for this package you need to install its dependencies first:
+
+    $ composer install
+
+After that you can run all PHPUnit tests like this:
+
+    $ vendor/bin/phpunit
+
+The tests are organized in fixture files. If you want to run a single test use the filter argument:
+
+    $ vendor/bin/phpunit --filter function-length-no-blank-lines
