The math is clear. The old approach cost $978,000 in rework. The new approach saved $934,000. Start with your next feature this week. Build the four practices. Stop losing money to compliance violations.

Letting the implementation details of the Subject Under Test seep into your test code quickly becomes problematic. It harms readability, forcing readers to decipher the testโ€™s behavior, sometimes even debug it, just to understand whatโ€™s happening. Tests should be simple and easy to understand! Thatโ€™s why itโ€™s crucial to keep the domain knowledge in the production code, and out of your tests.

Yay! The tests I wrote this evening failed! And then after I wrote a bit of code most of them passed. Bit more to do tomorrow.

A story about why #TestDrivenDevelopment matters

This week, I have been working on an invoicing system in a legacy codebase. The requirements are to extend the invoice report with additional custom fields. What we'll test here is not the visual, but the (in-memory) field values that are ultimately displayed on the invoice report.
So I first wrote the test for the header fields, _let the test fail_, and continued with the actual implementation until the test passed...
