		+	PHPUnit is a testing framework used to automatically verify that your PHP code behaves correctly. In this course, PHPUnit is used to test procedural PHP applications. Your application code does not need to use classes.

		+	=== Key Concepts ===
		+
		+	Your application code may be procedural (functions, <code>$_GET</code>, etc.)
		+
		+	Your test code must use a class because PHPUnit requires it
		+
		+	Tests are executed from the command line
		+
		+	Tests simulate browser behavior but do not use a web browser
		+
		+	=== File Layout ===
		+
		+	Your test file should be placed in the same directory as the PHP file being tested.
		+
		+	Example:
		+
		+	<pre> calculator.php CalculatorTest.php </pre>
		+
		+	=== Writing a PHPUnit Test File ===
		+
		+	A PHPUnit test file must:
		+
		+	Define a class
		+
		+	Extend <code>PHPUnit\Framework\TestCase</code>
		+
		+	Contain methods whose names start with <code>test</code>
		+
		+	Example:
		+
		+	<syntaxhighlight lang="php"> <?php use PHPUnit\Framework\TestCase;
		+
		+	class CalculatorTest extends TestCase
		+	{
		+	public function testAdd()
		+	{
		+	$this->assertEquals(5, add(2, 3));
		+	}
		+	}
		+	</syntaxhighlight>
		+
		+	Even though your calculator does not use classes, the test file must use a class so PHPUnit can discover and run the tests.

-Another useful function to know is the '''readfile''' function. It takes a file on the webserver's file system and sends it to the web browser. A simple example is given below, but note that you'll probably need to specify addition header fields in order to have the web browser download the file correctly.
