Not Taking My Own Advice
The other day I was pairing with a friend of mine on an app I call "Kid-Bank" (tracking how much money my son has, since he doesn't have his own bank account). We were making nice progress, doing basically the BDD->TDD->BDD cycle: discuss a user story ("show current balance"), make an integration test (using MockMvc from Spring Boot) that fails, then drop a level to test-drive the implementation of the core Domain code, popping back up when we think we're done and the integration test should pass. All good stuff.
Until...
