+Predis ships a comprehensive test suite that uses __PHPUnit__ to cover every aspect of the library.
+The suite is organized into several unit groups with the PHPUnit `@group` annotation which makes it
+possible to run only selected groups of tests. The main groups are:
 
-  - __disconnected__: generic tests that verify the correct behaviour of the
-  	library without requiring an active connection to Redis.
+  - __disconnected__: generic tests verifying the correct behaviour of the library without requiring
+    an active connection to Redis.
   - __connected__: integration tests that require an active connection to Redis
   - __commands__: tests for the implementation of Redis commands.
-  - __slow__: tests that might slow down the execution of the test suite, they
-    can be either __connected__ or __disconnected__.
+  - __slow__: tests that might slow down the execution of the test suite (either __connected__ or
+    __disconnected__).
 
 A list of all the available groups in the suite can be obtained by running:
 
 ```bash
 $ phpunit --list-groups
 ```
-Groups of tests can be disabled or enabled via the XML configuration file or the
-standard command-line test runner. Please note that due to a bug in PHPUnit,
-older versions ignore the `--group` option when the group is excluded in the XML
-configuration file. More details about this issue are available on [PHPUnit's bug
-tracker](http://github.com/sebastianbergmann/phpunit/issues/320).
 
-Certain groups of tests that require native extensions, such as `ext-curl` or
-`ext-phpiredis`, are excluded by default in the XML configuration file. If you want
-to test Predis using the phpiredis-based connection or against an instance of Webdis,
-you should remove those groups of tests from the exclusion list in `phpunit.xml`.

-generate a file with the scheleton of a test case to test a Redis command by specifying
-the name of the class in the `Predis\Command` namespace (only classes in this namespace
