Parallel execution is a great way to speed up almost any test suite, but for a long time, running tests in parallel with Cucumber has been challenging. But there is great news on this front: Cucumber 6 supports parallel execution of features in JUnit natively. And if you are using Serenity BDD with Maven, this…
A guest post from Andreas Worm (source: https://www.linkedin.com/pulse/atdd-all-things-andreas-worm) Why would you test the frontend, if you are not confident that the backend is performing correctly? In this article we utilize Serenity BDD and the screenplay pattern. Due to the added level of abstraction, it allows for defining "given-when-then" type scripts to be implemented on the…
Modern web applications are asynchronous by nature. So knowing how to wait for elements, before trying to interact with them, is an essential skill in modern test automation. Many testers pepper their web tests with Thread.sleep() statements, but this is the sub-optimal at best. It slows down the tests, makes them more brittle, and can…
Cucumber 4 has a lot of new features which can help make our Cucumber test automation code cleaner and more expressive. But there are also some big changes under the hood! Fortunately, Serenity BDD is here to help. The Serenity BDD Book has a brand new and very detailed guide on working with Cucumber 4,…
When we write automated acceptance tests we often need to perform some initial tasks to prepare test data or set up the test environment. Likewise, when a test finishes, we often need to tidy up the database or put the environment into a clean state. With Serenity BDD and Cucumber, there are several ways to…
Assertions are an important part of any test automation framework, and Serenity gives us many options. You can of course use standard JUnit, Hamcrest or AssertJ assertions at any point in a Screenplay test. But more recent versions of Serenity Screenplay provide an alternative approach, which many developers find easier to use and faster to…
Serenity is primarily designed to report the results of automated acceptance tests. However, there are times when some tests need to be done manually. And it is useful to report these tests in the overall test reports, to get a broader picture of test coverage. To make this easier, Serenity with Cucumber provides some support…
Executable specification written in Gherkin are a great way both to document an application’s behaviour, and to demonstrate that it works. QA folk can use the generated living documentation to verify both that the feature does what the business expects of it, and that the feature actually works. Because of this, BDD living documentation plays…
Running parallel tests in Cucumber with Serenity BDD has always been tricky. Until now. People often ask me how to run their Cucumber/Serenity BDD test suites faster. Fast feedback is key to a smooth build pipeline and to an effective test suite. A quick-running test suite means we can know when something goes wrong, and…
When we are working with BDD test automation tools such as Cucumber and JBehave, it often comes in handy to run an individual scenario in isolation. In this article, we look at how to do this using Serenity BDD. JBehave In JBehave, you need to use tags to identify the scenario you want to run….
IntelliJ provides excellent integrated support for Cucumber feature files. You can even run features simply by right-clicking on the feature file. But this won’t work when you are using Cucumber with Serenity, as Serenity needs to instrument the feature file before execution. Fortunately, this is easy to fix. Here’s how: Click on the feature file you…
Whether you are using Cucumber, JBehave or just JUnit, Serenity BDD encourages a layered, structured approach to automation. The reason for this is simply that it makes the tests easier to understand and maintain, and faster to write in the medium term. But people often wonder what is the best approach to share information between…
So you have Page Objects in your test automation suite? That’s great! But it’s not enough! Page Objects are a great start, but you need to go further if you want truly sustainable, high quality test automation. The Page Objects origin story Page Objects are a popular automated web testing pattern first implemented for Selenium by Simon…
Serenity BDD is an open source library that makes it easier to write high quality, maintainable automated acceptance tests. Serenity BDD has strong WebDriver integration, and manages the WebDriver instances for you. You almost never need to create or close your own WebDriver instance. Chrome gives WebDriver developers a great deal of control, with many…
Too often, our acceptance tests end up as sequences of “click”s and “select”s running against a web application. This makes our tests hard to understand and hard to maintain. User-centric, task-driven test automation shows us a better way. When we learn something new, it is easy to get stuck in a low-level, details-focused way of…
