“Shift left” is one of the latest buzz terms in software testing. Movements like agile and DevOps recommend that testers shift left, but what does that mean, exactly? Here's how one tester became a believer in the shift-left movement; how he got his team's developers, analysts, designers, and managers on board; and how his entire organization has benefited from the shift.
From his decade of teaching thousands of professional software developers how to be effective with test-driven development, David Bernstein has learned that there are three key ingredients for mastering TDD: understanding what it really is, making code reliably testable, and getting hands-on experience. Let’s look at each of these factors to see what it takes to use TDD effectively on your projects.
You may feel you don't have time to write unit tests, but you really don't have time not to. Steve Poling makes the case that writing tests first not only will yield better code, but will help you get that code working right sooner. Here's how using a test-first approach changes your thinking about coding, lets you see mistakes immediately, and helps you create more testable code.
A decade ago, continuous integration became a key practice to support the agile process. Now, the hot topic is continuous delivery, and Pini Reznik has noticed many similarities between the adoption of CD today and the implementation of CI. You can learn a lot from past experiences.
Because enterprise applications are highly interconnected, development in stages puts a strain on the implementation and execution of automated testing. Service virtualization can be introduced to validate work in progress while reducing the dependencies on components and third-party technologies still under development.

In this interview, Alex Martins, the CTO of continuous quality at CA Technologies, explains how continuous testing, continuous integration, and open source testing tools can help modern software teams keep up with the speed and demands of agile.
Steve Berczuk is a regular contributor to TechWell and StickyMinds and a principal engineer and ScrumMaster at Fitbit in Boston. In this interview, Steve discusses configuration management and agile, helpful tools, and how testing has evolved over the years with the rise of agile.
Hans Buwalda's experience covers being a developer, manager, and principal consultant for companies and organizations worldwide. In this interview, Hans talks about using keywords effectively, tests that have too many details, and the changing testing industry.
To emulate production-like conditions that cannot be tested on the unit level, many integration and functional tests need a realistic environment. However, performing these tests in a production-like environment is fraught with problems—test data management issues, tests that are difficult to execute repeatedly, and network traffic that causes long-running test execution times. Instead of having to deal with these problems and others, Irene Dhong employs Docker to simulate dependencies. Learn how you can take advantage of Dockerized dependencies for quick test writing, reusability of common development code, and the ability to test early and often on a very low functional level. Irene describes how her development team is using Docker to implement more effective TDD and unit testing environments because Docker utilizes similar infrastructure both on the development and DevOps side. Join in to get Dockerized, too.
As IT systems increase in both scale and complexity, delivering quality applications becomes more challenging. In addition to creating and executing test scenarios, testers need to create and maintain the test data that enables test execution. Test data management (TDM) creates and...

In chess, the word blunder means a very bad move by someone who should know better. Even though functional test automation has been around for a long time, people still make some very bad moves and serious blunders. The most common misconception in automation is thinking that manual...
We can all learn valuable lessons from game development where, in addition to functional performance, overall experiential quality—user experience (UX)—is of critical importance. Blockbuster game development presents particular challenges with regard to scale, rapid iteration, and fuzzy...
