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.
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.
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.
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.
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.
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...

Test-driven development (TDD) is fundamental to agile, but to most of us caught up in projects, there's never enough time to commit to it. Erick Fleming shows how to use TDD to improve product quality and time to delivery.
