Writing Automated UI tests in NET using Playwright and SpecFlow by Ivan Stoev

To help folks improve their Gherkin skills, Gojko Adzic and SpecFlow are running a series of #GivenWhenThenWithStyle challenges. I love reading each new challenge, and in this article, I provide my answer to one of them. Third, continuous testing boosts customer confidence in PrecisionLender. Customers trust the software quality because they know that PrecisionLender thoroughly tests every release.

Some editors like Visual Studio Code and similar IDEs work great for engineers but aren’t suitable for product owners and non-programmer Amigos who want to contribute. Other editors like Notepad++ and Atom are lighter in weight but still require extensions and a little expertise. Fancy BDD tools like CucumberStudio and Cucumber for Jira provide Gherkin editors together with a bunch of other nifty features, but they require paid licenses. Let’s break down the example scenario given above to see how to write Gherkin with style for user interface tests. Good Gherkin means good behavior specification, which results in better features, better tests, and ultimately better software.

Integration With Visual Studio

About a dozen different tests fail every night, and Jeremy spends a lot of time each morning triaging the failures. Whenever he reruns failed tests individually on his laptop, they almost always pass. If someone is manually running the test, then they will pause and poke around to learn more about the problem. However, when an automated test fails, the rest of the suite keeps running. Testers won’t get to view results until the suite is complete, and the automation won’t perform any extra exploration at the time of failure.

In October 2020, Q2 released Boa Constrictor as an open-source project so that anyone can use it. It is fully compatible with SpecFlow and other .NET test frameworks, and it provides rich interactions for Selenium WebDriver and RestSharp out of the box.

GitHub Repositories

I have some example projects on GitHub in Python and Java with some basic unit, integration, and end-to-end tests, but I don’t have any large-scale examples that I can share publicly. Try doing Example Mapping on one or two stories to start. The first time is always rough, but as you iterate on it, you’ll get better as a team. The team won’t suffer through the inefficiencies of miscommunication and poor planning. You may even want to replace planning meeting with Example Mapping meetings.

In this SpecFlow tutorial for using SpecFlow Selenium C#, we will be using SpecFlow as the BDD interpreter. Once the feature file is parsed, the automation code corresponding to that particular Scenario is called. As we pointed out earlier in this SpecFlow tutorial, BDD is not a tool but a process that is an extension of TDD. It also brings the best practices of Agile software development and can be used even if your team is making use of the Waterfall model. The above example makes use of the most frequently used keywords in Gherkin i.e.

ChatGPT is Useless for Real Test Automation

They are thorough in their level of coverage for these small behaviors. However, not all behaviors may be equally important to cover. Some behaviors are simply more important than others, and thus some tests are more valuable than others.

This new feature file eliminates the first two scenarios and uses a Background section to cover the setup steps. It also eliminates the need for special Given steps in each scenario to set unique starting points. Implicitly, if the “Upload what is specflow Files” or “Spreadsheet Formats” links fail to display the expected elements, then those steps would fail. The four new scenarios I wrote each covers an independent, individual behavior of the fictitious Example site’s user interface.

This is a useful extension method in C# that can be used to check if a string contains only numeric characters

What makes it special is that it is designed especially for .Net projects. The DeviQA team has rich expertise in using this framework and can help you implement a decent QA process as well as gain desired results. Scoping functionality is available in Specflow which is not present in Cucumber. By defining the Scope, the same test definition can be used for executing multiple test scripts for automated software testing with SpecFlow.

• Before adding automated retries to the test suite, Jeremy was already manually retrying tests and disregarding flaky failures.
• Nevertheless, I strongly recommend using custom tags to denote manual tests, since there are many reasons why a test may be ignored .
• Other editors like Notepad++ and Atom are lighter in weight but still require extensions and a little expertise.
• Or, perhaps features in the web app itself are behaving unexpectedly.
• Scenarios are written in CycleScript, a Gherkin-ese language with additions like variables and sub-scenario calls.
• More than that, you can test in real user conditions with network simulation and geolocation testing for uncompromising quality.

Selenium and must also install Selenium on your system. In this SpecFlow tutorial, Selenium will help in automating our SpecFlow tests. The approach of this technique is to use language that could be easily understood even by a non-technical personality.

I will also review the automation code to make sure there are no unhandled race conditions. I might even need to rerun the test multiple times to measure a more accurate failure rate. Testers love to find consistent, reproducible failures because those are easy to explain. Other developers can’t push back against hard evidence. However, intermittent failures take much more time to isolate. They might be triggered by environmental factors or awkward timings.

PrecisionLender’s SETs developed Boa Constrictor, a .NET implementation of the Screenplay Pattern, to make better interactions for better automation. In Screenplay, actors use abilities to perform interactions. For example, an ability could be using Selenium WebDriver, and an interaction could be clicking an element.
