TDD anti patterns - episode 5 - with Sofia Carballo and Juan Pablo

Testing practices has increasing its adoption by developers, shifting left the test responsibilities

And increasing the quality of the code, besides that, continuous testing is an agile practice that impacts the software development life cycle. In this talk we are going to focus on the following TDD anti-patterns: The stranger, The operating system evangelist, Success against all odds and The free ride.

7. Anti patterns - Survey takeaways
   1. Survey notes: Javascript, PHP and Java were the most used programming languages
   2. Survey notes: Practitioners usually informally learn TDD
   3. The anti patterns covered were related to test last
   4. Subjects we touched around testability: SOLID, Object calisthenics, Non-determinism and the
   test pyramid
   5. Examples are from open source projects and also extraction from real code bases

17. 2. The stranger - 🏆 7
    A test case that doesn’t even belong in the unit
    test it is part of. it’s really testing a separate
    object, most likely an object that is used by the
    object under test, but the test case has gone and
    tested that object directly without relying on the
    output from the object under test making use of
    that object for its own behavior.

45. 4. Success Against All Odds - 🏆3
    A test that was written pass first rather than
    fail first. As an unfortunate side effect, the
    test case happens to always pass even
    though the test should fail.
