I have seen the power of Selenium and that it can give you the tests in different languages.

So the question is, why should I use PHPUnit or Lime (for Symfony) when a solution like Selenium is available?

Isn't it time-consuming to write all the tests by hand, when you can just use Selenium?

phpunit and selenium do not test the same things phpunit test a unit of code selenium is designed for testing integration/functional testing of several modules together.

I think you need both types of tests. phpunit for unit testing and selenium for interface testing. The phpunit manual even explains how to integrate the two.

http://www.phpunit.de/manual/3.6/en/selenium.html

Also this article explains the purpose of both. http://software-testing-zone.blogspot.com/2007/01/unit-testing-versus-functional-tests.html

I understand the desire to use selenium for everything it seems so simple, you can just click and write a test, but it really is a a case of needing both. You may want to pick up a copy of "Expert PHP 5 Tools"

It covers the different types of tests and their use quite well.

Well in the case of sf+lime there is some good integration directly in the framework. And lime is so simple that tests take little time to write at all. Personally i prefer phpunit, but when i use symfony i just stick with lime because its the path of least resistance and sppeds things up. There is/was a php unit plugin for sf but ive never used it - i figured why bother. Now for other non-sf projects i use phpunit when needed simply because its no more difficult than hooking up lime.
