Managing state between steps
Posted Tuesday, February 21, 2012
Sometimes it's useful to be able to pass information between steps. For example, you might need to check that a client's details entered into a registration form appear correctly on a confirmation page later on. You could do this by passing values fromore »Faster Web Tests with Parallel Batches in Thucydides
Posted Saturday, December 24, 2011
Web tests are as a rule much slower than other types of tests, but they can be sped up significantly by running them in parallel. However, this is often harder to implement than it sounds. The latest version of Thucydides (version more »Some useful new Hamcrest matchers for collections
Posted Sunday, December 11, 2011
Hamcrest is a neat little library that lets you write more fluent and readable tests. For example, rather than writing: assertEquals("red", color); you would write: assertThat(color,is("red")); This makes for tests that express their intent muchmore »Code Coverage as a refactoring tool
Posted Sunday, May 15, 2011
Using code coverage to help with refactoring, when combined with TDD, is a powerful tool. This article discusses how. I am a big fan of using code coverage as a developer tool to promote more reliable, better tested codmore »Integration Test Driven Development - the Vietnam of TDD
Posted Monday, May 9, 2011
Sometimes, even if you are generally applying good Test Driven Development practices, you can find yourself slipping into what I call Integration-Test Driven Development, or ITDD. Essentially, this is when you use a high level integration or functional more »Code coverage metrics and Functional Test Coverage
Posted Tuesday, May 3, 2011
There have been some articles and tweets about code coverage recently, and it seems that many developers are still laboring under a few misconceptions in this area. Code coverage can be a very useful metric. However you need to know how, and whenmore »Presentations
Completing the circle - Automated web tests as a team communication tool

By John Smart
Acceptance Test Driven Development, or ATDD, has proven to be a very effective technique, both for driving and guiding development, and for enhancing communication between developers and other project stakeholders. But why stop there? Well designed Acceptance Tests can also act as a formidable documentation source and communication tool. Indeed, when written in a narrative, BDD-type style, Acceptance Tests have the potential to document in detail how the user interacts with the application.
In this talk we will look at the role of automated Acceptance Tests not only for testing, but also as part of the whole development lifecycle, from writing the user stories right through to deploying the application. We will also look at ways to make your automated acceptance tests more expressive and how to use them more effectively as a communication, reporting and documentation tool.
Finally, we will present and demonstrate a new open source library that helps developers and testers write automated acceptance tests for web applications using WebDriver/Selenium 2. This library also produces clean, narrative-style reports illustrated with screenshots that effectively describe the application's functionality and behaviour, as well as any regressions or pending features.
JUnit Kung Fu: Getting More Out of Your Unit Tests
By John Smart
JUnit is the de facto standard in Java testing. Yet many advanced JUnit features are little known and poorly understood. This session reviews some lesser-known features of JUnit, along with a few associated libraries, that can make your unit tests more powerful, expressive, and fun. The session is intended for Java developers, lead developers, and architects trying to introduce good testing practices into their teams.
Attendees will learn about the latest JUnit tips and tricks, including: - The fine art of naming your tests - Writing clearer and more expressive tests with Hamcrest and Mockito - Data-driven testing in JUnit with parameterized tests and theories - Using JUnit rules to extend your test cases and writing your own rules to customize JUnit - Extending JUnit by writing your own test runners
Jenkins Continuous Integration in Action
By John Smart
The team dynamics and agile process revolution of the last several years has taught us that continuous integration (CI) is a necessary part of a healthy agile team. Jenkins (formerly Hudson) is the idea and footprint leader in the CI space. A recent survey stated that over 70% of all CI installations have Jenkins in their DNA. What's so awesome about this particular CI tool?
Get on board with a ground-up survey of how to install, apply, upgrade, and leverage the free an open source Jenkins Continuous Integration server for your build, whether it be Ant, Maven, Gradle, JavaScript, Rake, or just shell scripts.
In this presentation, you'll learn how to add plugins for additional build and analysis phases, how to cluster Jenkins on a subnet for a swarm of CI servers that automatically load balance and collate reports, and lastly, how to manage Jenkins on a disparate set of OSes to natively test your unit and integration tests on all your supporter platforms.
