“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.

Three different colored keys 3 Keys to Mastering Test-Driven Development

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.

Using Agile and DevOps to Achieve Quality by Design Using Agile and DevOps to Achieve Quality by Design

When software nears completion, it is the wrong time to focus on quality. Product delivery improves if you invest in a plan, validate in small increments, and focus on continuous testing.

Test-Driven Service Virtualization Test-Driven Service Virtualization

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.

STAREAST 2018 Integration and Functional Testing Using Dockerized Dependencies
Slideshow

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.
