I was originally excited about the embrace that Drupal seemed to have given to testing.

However after spending some time with it I've concluded that Drupal really isn't very test friendly.

Most tests for Drupal are integration tests not unit tests.

That is to say that they test a bunch of components together - not each bit separately.

This is because Drupal components (modules or functions) are not well encapsulated, global variables are used, data is cached within functions,  passed via the database etc. 

I had fun this weekend at the PHP London Test Fest, it was a great opportunity to learn something new and meet some great programmers.

I recently finished work on a project that really suffered from a lack of build tools.

It was a large project, and while many of us were keen on writing tests we weren't able to get management sign of to spend some time automating the test process. So even though we did some of the work we didn't get all the benefits.

It was really frustrating to come back to a piece of work that was well covered by unit tests, only to find those tests broken
