Novice phpUnit

Question

As a shoulod, I started using phpUnit as a testing base for a bunch of functions and classes that I have already done?

---

EDIT: yes, I already read the documentation. I mainly tried the tests, following the example of BankAccount. But I get errors:

Warning: require_once(PHP/CodeCoverage/Filter.php) [function.require-once]: failed to open stream: No such file or directory in [...]/unitTest/phpunit.php on line 38.

In addition, php scripts start with #!/usr/bin/env php, which indicate that they should be run from the console. I would rather run them from a browser ...

Suppose I have a function f1()that returns a string. How should tests be done? Did I miss something?

, php set_include_path(), phpunit . ...

.

// you will have to write your own class here that collects the tests
$collector = new Unit_Test_Collector();
$suite = $collector->getSuite();

//$config is an array of phpunit config options

PHPUnit_TextUI_TestRunner::run($suite, $config);
