Code coverage vs. test coverage: Why you need both to ensure high quality releases
Humans are – well human – and can make mistakes. These mistakes can lead to errors or defects in your software or application. Thorough test plans and effective execution of those plans can ensure a product is high quality – but how can you measure their effectiveness? Popular approaches include counting the number of lines covered by tests or taking a functional approach and seeing if all the features are covered – but this “test everything” strategy will quickly become untenable as your code base and the number of test scenarios grows.
In this white paper we’ll discuss the pros and cons of two ways to measure testing effectiveness – code coverage and test coverage – and contrast them to understand which method is better suited to which product and software development method.
