+# UtilityPHP Unit Tests #
+
+### Introduction
+
+This is the testing documentation for util.php. The unit tests require PHPUnit,
+and can be run in your web browser.
+
+### Requirements
+
+PHP Unit >= 3.5.6
+
+#### Installation of PHPUnit
+
+    # Download the PHPUnit phar.
+    wget https://phar.phpunit.de/phpunit.phar
+
+    # You can just run it locally. (Preferred for Windows)
+    php phpunit.phar --version
+
+    # Or install it system-wide.
+    mv phpunit.phar phpunit
+    chmod +x phpunit
+    sudo mv phpunit /usr/local/bin
+    phpunit --version
+
+## Test Suites:
+
+util.php includes a phpunit config file, so just run `phpunit` from the working
+directory to run the test suite.
+
+```
+phpunit
+```
+
+If you want code coverage reports, use the following:
+
+```
+phpunit --coverage-html ./report
+```
