Test Driven Development for Embedded C

We Don’t Have Time

We all need more time. Where will we find time to write all this test code? There is barely enough time to write the production code we need. There are more lines of test code than production code for the LedDriver. But does that really matter?

If people programmed error-free and at a constant rate, then there is some reason for concern. But people do neither. The time-consuming parts of programming are thinking, problem solving, and confirming solutions. Confirming solutions can be done many ways, Debug Later Programming (DLP) or TDD to name two. The important question is, did writing the test impede or speed your progress?

Many proficient practitioners proclaim that TDD makes them go faster. They report a productive ...
