Ping Pong is a Test Driven Development (TDD) based pairing technique. Here are the steps:
- Write a new test and run it to see that it fails.
- Pass control to your pair, who will implement the code required to make the test pass.
- Implement a new failing test and pass control back.
This technique is great for practicing your TDD skills, building up a great test suite and takes away any doubt about when to switch driver.
