Testing Green Field Applications vs. Legacy Applications

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…

What is Acceptance Test Driven Development (ATTD)?

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. Typically, a single acceptance criteria might map…

What are Executable Specifications or Specifications by Example?

Requirements and tests are just two sides of the same coin. You can’t have a user story or requirement without an acceptance criteria (test). These two meld into executable specification. Using gherkin syntax (given,when,then) we can represent requirements using examples and create specifications by example. As a potential customer I want to collect books in a…

What is Test Driven Development (TDD)?

Test driven development is a programming approach where before the developer writes any code, she first writes an automated test. This test will fail at first because no code exists.

What does your task board say about your team? Many teams have a separate testing column. This indicates that we are still doing hand-offs from development to testing and that testing is an afterthought.
