 This is the quick-start to CodeIgniter testing. Its intent is to describe what
 it takes to get your system setup and ready to run the system tests.

 ## Requirements
 
 It is recommended to use the latest version of PHPUnit. At the time of this
-writing we are running version 8.5.9. Support for this has been built into the
+writing we are running version `9.x`. Support for this has been built into the
 **composer.json** file that ships with CodeIgniter, and can easily be installed
 via [Composer](https://getcomposer.org/) if you don't already have it installed globally.
 
-	> composer install
+	composer update
 
 If running under OS X or Linux, you can create a symbolic link to make running tests a touch nicer.
 
-	> ln -s ./vendor/bin/phpunit ./phpunit
+	ln -s ./vendor/bin/phpunit ./phpunit
 
 ## Running the Tests
 
-The entire test suite can be ran by simply typing one command from the command line within the main directory.
+The entire test suite can be ran by simply running the command below:
 
-	> ./phpunit
+	./phpunit --filter AllLocalesTranslationTest
 
-## Generating Code Coverage
+To run the specific test suite for a locale, simply provide the class name of the locale-specific test:
 
-To generate coverage information, including HTML reports you can view in your browser,
-you can use the following command:
+	./phpunit --filter FrenchTranslationTest
 
-	> ./phpunit --colors --coverage-text=tests/coverage.txt --coverage-html=tests/coverage/ -d memory_limit=1024m
-
-This runs all of the tests again, collecting information about how many lines,
-functions, and files are tested, and the percent of the code that is covered by the tests.
-It is collected in two formats: a simple text file that provides an overview,
-as well as comprehensive collection of HTML files that show the status of every line of code in the project.
-
-The text file can be found at **tests/coverage.txt**.
-The HTML files can be viewed by opening **tests/coverage/index.html** in your favorite browser.
+Locale-specific test class names follow the named regex pattern `/^(?P<locale>[A-Za-z]+)TranslationTest$/`.
 
 ## PHPUnit XML Configuration
 
 The repository has a ``phpunit.xml.dist`` file in the project root, used for
 PHPUnit configuration. This is used as a default configuration if you
 do not have your own ``phpunit.xml`` in the project root.
 
-The normal practice would be to copy ``phpunit.xml.dist`` to ``phpunit.xml``
-(which is git ignored), and to tailor yours as you see fit.
-For instance, you might wish to exclude database tests
-or automatically generate HTML code coverage reports.
