The London School of Test-Driven Development focuses on testing how different parts of a program talk to each other. It uses mock objects to check these interactions instead of looking at final states. This skill brings that approach into a swarm of AI agents working together on code.
You can write tests that start from the outside, like a user clicking a button, and then work inward to the details. The skill helps you set up mock expectations and verify that objects collaborate correctly. It also coordinates with other testing agents in the swarm to cover all behaviors.
Teams that need clear contracts between software parts will find this useful. It makes sure every object plays its role by checking how they interact, not just what they return. The result is reliable and collaborative testing across a whole project.
