From a management standpoint, Test-Driven Development (TDD) can be a difficult sell. Tempting as it is to cut testing in order to reach the next milestone in the project, it is a mistake because, as we’ll see, TDD can help us accelerate development and reduce costs over a project’s lifecycle.

One of the success factors for Agile and DevOps is developers changing the way they work and adopting practices like Test-Driven Development (TDD). It’s not something that just happens by itself, and many of the “usual” ways of introducing change fail for TDD.

Back in 2014 I wrote a blog post listing three mistakes often made by folks who are new to test-driven development (TDD). We’re doing TDD, but we have no code to test; we have nothing to hang our first test on, so we need to invent something, fast! The three mistakes I identified are: Starting with error cases or null cases.

While these can be tested through end-to-end tests running in the browser, such tests are slow and more work to maintain than unit tests.
