Unit Testing Costs and Benefits

March 10, 2015 0

There is always a lot of discussions about the costs and benefits of unit testing. The opposition was exacerbated by the adoption of Test-Driven Development (TDD), a technique that recommends writing unit tests before you write the code. In this blog post, Steven Sanderson discusses unit testing with a costs and benefits perspective.

Test, Transform and Refactor

November 27, 2014 1

Let’s have a close look into the Red-Green-Refactor cycle and understand the subtleties of each step. When we go down the rabbit hole of Test Driven Design (TDD), we sometimes take too big steps leading us to many failed tests we just can bring back to green without writing a lot of code. We need to take a step back and take the shrinking potion of baby steps again.

November 24, 2014 0

This presentation looks at the chasm-crossing potential of Test-Driven Development (TDD) and some related technologies. The aim is that you will still be able to get a good software development job in 2024.

Strict Test-Driven Development

June 10, 2014 1

Agile testing and test automation are almost mandatory for projects that demand high quality as well as short release cycles like Scrum. It acts as a safety net in order to protect existing functionality against bugs resulting from unintended side-effects of recent changes. Software developers “in the trenches” often automate their tests but don’t practice strict Test-Driven Development (TDD).

TDD: Tell, Don’t Ask

March 13, 2014 0

Test driven development follow this pattern: Setup – Execute – Verify the new state. Asking the system under test for its new state has traditionally been done to check the new state. This can create problems with the Law of Demeter. The system under test knows unnecessary much about the objects it is collaborating with.

Outward-in Development, Unit Tests and Fixture Data

Test-Driven Development (TDD) can be difficult to practice as features increase in complexity. Testing is often skipped when developers feel uncomfortable with TDD or have not yet seen certain approaches in practice. This video describes specific techniques used in TDD which touch on: Integration testing with RSpec+Capybara, Model Associations and Data Validations, Asynchronous Jobs, Emails, 3rd Party Services, and JSON API endpoints.

Adopting Test-First Development

December 9, 2013 0

This presentation incrementally demonstrates the concepts of Unit Testing, Test-Driven Development (TDD) and then Behavior-Driven Development (BDD) that enable us not just to create robust regression tests, but also clean and maintainable code.
