I'm now going under the bonnet of our components, and looking at the different file roles that the PEAR installer expects to find when we distribute our component as a PEAR-compatible package. One of the most important file roles allows you to ship your tests with your package - and it's vital that this is something that you get in the habit of doing routinely.

He recommends "testing your code and shipping your tests" along with the component(s) you're releasing. Not only does it help you create a better quality end result but also makes it simpler for other developers to make changes and know they're not breaking things. He describes unit tests for those not familiar and includes a specific example of the CommandLineLibrary and its related tests.

As you can see [below], we already got some examples and hope that everybody who ordered in advance got their examples by now, too. If you don't, stay tuned they should arrive soonish. We are both absolutely amazed by the printing quality and the overall impression of the book.
