We’ve written before about several characteristics of well written requirements, and one of those characteristics is testability. Ahamad has written an list of 10 tests of requirements, with an emphasis on assessing the testability of the requirements. The testability of the requirement determines if the resultant product can be tested to determine if it meets the requirement. (…)
TDD has become quite popular, and many companies are attempting to adopt it. However, some folks worry that it takes a long time to write all those unit tests and are looking to test-generation tools as a way to decrease that burden.
The burden is not insignificant. FitNesse, an application created using TDD, is comprised of 45,000 lines of Java code, 15,000 of which are unit tests. Simple math suggests that TDD increases the coding burden by a full third!
Of course this is a naive analysis. The benefits of using TDD are significant, and far outweigh the burden of writing the extra code. But that 33% still feels “extra” and tempts people to find ways to shrink it without losing any of the benefits. (…)
