PHPUnit runs only from the command line. Why?

Question

I have the following code:

<?php
    class MyTest extends PHPUnit_Framework_TestCase
    {
        public function testCalculate()
        {
            $this->assertEquals(2, 1 + 1);
        }
    }
?>

When I open the PHP file in the browser, I get the following error:

Fatal error: Class 'PHPUnit_Framework_TestCase' not found

However, if I use the command line it works fine: phpunit [local_path_here]/testcase.php

Result:

.

Time: 0 seconds, Memory: 5.00Mb

OK (1 test, 1 assertion)

Why is that? How can I make it to run it in the browser as well?

You can integrate add-on for running unit tests via native web GUI:
