If you're using test-driven development, don't measure unit test code coverage. To improve code and test practices. If you're trying to improve your team's coding and testing practices, perform root-cause analysis 1 of escaped defects, then improve your design and process to prevent that sort of defect from happening again.

The most successful software development movement of my lifetime is probably test-driven development or TDD. With TDD, requirements are turned into very specific test cases, then the code is improved so the tests pass. Using TDD to Drive Better Code. TDD has some powerful things going for it.

James Shore, author of the book “The Art of Agile”, wrote an article that covers the alternatives to acceptance testing. The way you write an acceptance test is to take a user story and then write code that tests the end result of a software process. When it comes to testing, my goal is to eliminate defects.

TDD, when conducted as a specifying activity, is an aspect of Behavior-Driven Development (BDD). Behavior is what we specify and is what we “drive” into the system using tests. Therefore, when structuring the tests in TDD we can be guided by the language of BDD: Given, When, Then.

Because TDD is “test” driven development, people tend to think of TDD as “writing tests first.” In fact, TDD is not a testing activity per se. It is the creation of an executable specification prior to the creation of each system element. Unit tests are a very useful by-product of this process.

TDD is typically part of an agile process. This means that we embrace change, that new requirements flow into the team’s work either on a time-boxed pulse, or through some kind of pull system (like Kanban). In TDD, a new requirement always starts out as a new, failing test or “specification.”

TDD depends on a strong connection between the automation of the test suite and the system itself. The suite should record the specification that is implemented in the system, and the connection allows this to be confirmed at any point. The problem is automated tests pass by default.

In TDD, tests take actions such as Setup, Trigger, and Verify. Each of these pieces must successfully execute in order for the specification to be verified as accurate to the current behavior of the system. If there is an external dependency, the test can become vulnerable to a failure of that entity.

The term “workflow” in this sense is meant to indicate the way two system elements interact when performing a task. Often these interactions themselves are not exposed outside the system, and so only their resulting behavior should be tested. This is as true in TDD as it is in traditional testing.

The biggest is Test-Driven Development (TDD) , thanks to Kent Beck and his Xtreme Programming crew. TDD says you write tests before writing any code, because this pushes you to design the code in ways that are testable, with APIs that are usable. TDD is a great design practice.

Automated tests are important. Unfortunately, many automated tests also waste a huge amount of time. The easy, obvious way to write tests is to make broad tests that are automated versions of manual tests. It’s also easy to make poor-quality tests that are hard to read, or end up only testing themselves.
