Unit Testing

From Missoula Bar Camp

• The business logic is what needs the best testing – and unit tests are the right tool to handle this.

• The core of unit testing is assertions
  • "I assert that adding an answer will result in one more answer being associated with this topic"

• First you have a failing test, and then you do the simplest possible thing to make it pass, then refactor as necessary

• Developers could/should adopt a flow in which they run their unit tests as they change things, and then prior to building your package run your selenium tests.

• Best if you can make use of transactions in the database – so you blow it away afterwards

• Tools:
  • selenium – firefox plugin – a macro recorder so you can build real browser tests.
  • php: simpletest package
