On the QaFoo blog there's a recent post interviewing Johann Peter Hartmann, the CTO of Mayflower, about current PHP testing practices and how to find that "sweet spot" that works for your development.

Talking to interesting people spawns ideas and spreads insight knowledge. Therefore, I talked to Johann Peter Hartmann about testing culture and how PHP projects should approach testing in 2013.

They talk about things like:

• The move from "spaghetti code" to "quality code"
• A discussion of the current tools
• Defining a unit testing strategy
• Test Driven Development

They also talk some about the training that the QaFoo folks provided to help them (Mayflower) work all of this out for their organization.
