These types of tests are non-scripted and thus cannot be automated. These tests need human interaction, observation, analysis, and intuition. With usability testing, a human needs to verify that the design, layout, and user interface…

When you are coming up with a testing strategy for green field applications, you should follow the testing triangle or pyramid. For legacy application, a different strategy is needed. Writing tons and tons of unit tests when working with a very large application with zero tests is very costly and results in very little benefits. A…

Acceptance test driven development takes the TDD practice and applies it to acceptance tests. On day 1 of the Sprint, before we begin coding a particular user story, we start by reviewing the acceptance criteria and thinking about how we will verify via tests that this story is complete.
