TDD document links needs to change #179
Description
replace the link to "Test Driven Development (TDD): The Advantages and Disadvantages" with a non-paid one (from freedium.cfd but it's the same article).
replace the link to "Introduction to Test Driven Development (TDD)" with another one (from developers-books.com but it's the same article) because the original link returns a 410 error. (This account is under investigation or was found in violation of the Medium Rules)
