Cucumber testing is a behavior-driven development technique. BDD is an approach to software development that focuses on defining the behavior of an application as concrete examples before writing the code. This helps developers to understand how the application should behave. It also helps developers to collaborate with stakeholders to build more correct and more accessible applications. All Cucumber feature files contain clearly structured Given When Then test scenarios.
We can use Cucumber along with Watir, Selenium, and Capybara, etc. It supports many other languages like PHP, Net, Python, Perl, etc. Framework can be used to test different aspects of the software.
- Screenshots can help debug purposes or for creating reports.
- I am looking to get started building a project and want to use CUCUMBER from day one.
- My Ruby background is Intermediate; however, I do have a good understanding of MVC and the structure within Ruby.
- Automation testing on a cloud-based Selenium Grid lets you run tests at an expedited pace across different browsers, platforms, and devices.
- Chapter 12 of The Cucumber Book deals with testing REST Web Services, as well as a wealth of useful advice on getting started with Cucumber in general.
- You may enter your suites and check test cases inside on the bird’s eye.
Additionally, it accrues technical disadvantages when working with text editors because they don’t read its syntax as a regular language. LearnAcademy Build ACCELQ skills for Agile testing From getting-started in ACCELQ to mastering the powerful capabilites of the platform. You may enter your suites and check test cases inside on the bird’s eye. This tutorial has all the information you need to work with BDD successfully. If you use another tool, change the testing tool you need.
We have successfully written our first test code with the Nightwatch.js. This will help you identify slow tests so that you can optimize them. Third, use a tool like Slack to receive notifications when your tests start and finish. Difficulty debugging failures can be caused by incorrect assumptions about how the application works or by insufficient specific tests. Another way to enhance your Cucumber tests is to take screenshots. Screenshots can help debug purposes or for creating reports.
Each method should be written in Gherkin syntax and include Given, When, and Then steps. Agile teams can use Cucumber to ramp up their application development projects since it helps them automate the testing and documentation processes. This is possible due to its ability to accommodate a wide range of stakeholders and create acceptance test cases most intuitively.
Second, use a tool like HeadSpin to run your tests on real devices or in the cloud. This will help ensure that your tests are running on fast enough devices to avoid flakiness. You can then schedule your tests to run at specific times or tag your scenarios so that they can be run together or separately. The HeadSpin platform will provide you with reports showing the results of your Cucumber tests. This keyword can be used to define steps that should be run before each scenario in a feature file. First, you’ll need to create a file with a .feature extension.

To use this library, you need to add it to your project’s dependencies. This command would generate an HTML report in the current directory. The report would contain information about the scenarios that were run and whether they passed or failed. The second and third rows contain the actual data that will be used in the test.
Flakiness can be caused by incorrect assumptions about how the application works or by tests that are too sensitive to changes in the application. Slow tests can be caused by inefficient test code or by running tests on devices that are too slow. For example, you could use a data table to test a login feature with a different username and password combinations. To use a data table, you must define the header row and the data rows in your .feature file. Using data tables is one way to make your Cucumber tests more robust.
Once you understand how Cucumber testing works, you can start writing your tests. Cucumber tests are written in a simple, natural language called Gherkin. You can learn more about Gherkin by reading the Cucumber documentation. Test code behind the Gherkin is written in proper programming languages for the project.
When this scenario is run, the login feature will be tested three times with different combinations of username and password. This can help avoid duplication and make your scenarios easier to read. It can also help you understand why a particular test might have failed. Use other tools to help write and run your Cucumber together as expected in the background keywords to avoid duplication. Let’s say you’re working on a project to create a new website.
Our teams will design, build and scale your ideas and make them a reality in the most efficient way. This can be achieved by building an in-house infrastructure or outsourcing to a third-party cloud platform like LambdaTest. Automation testing on a cloud-based Selenium Grid lets you run tests at an expedited pace across different browsers, platforms, and devices. Your automation tests can leverage the advantages of parallel testing in Selenium to run automation tests at a super-fast pace. In the previous section of this Cucumber test automation tutorial, we have created a “tests” folder.
Best practices for writing effective Cucumber tests
Enable screenshots in default settings of nightwatch.config.json file. You can enable HTML reporting in the framework by installing the required dependencies and minimal configurations. Reports in the HTML format are easy to read and understand.
Now, we will be creating test files inside this folder. Each file will be loaded as a test suite by the Nightwatch test runner. You may also create “nightwatch.conf.js” for configuration.

Another difference between Cucumber and traditional testing is that Cucumber tests are designed to be less likely to break when the code changes. This makes them more flexible and easier to maintain over time. Reduced development time, increased productivity, and more straightforward maintenance are all the positive outcomes of this.

By using Cucumber testing, teams can avoid misunderstandings and reduce the need for lengthy discussions about the code. Cucumber tests allow us to keep writing readable test code for humans to encourage collaboration than traditional code-based tests. Cucumber is also known as one of the best tools for agile development because it helps product managers and business analysts adjust the testable scenarios and the product accordingly. In that light, Cucumber helps reduce ambiguity in scope and design and enhance product quality before the final release.

How to Install and Configure Nightwatch.js
I am using Cucumber to automate the testing of services and controllers in my app. In addition, I am using the Cucumber Junit runner @RunWith(Cucumber.class)in the test steps. I need to instantiate my controller and was wondering if I could use Spring to autowire this.
Each scenario is a list of steps for Cucumber to work through. Cucumber verifies that the software conforms with the specification and generates a report indicating ✅ success or ❌ failure for each scenario. This tutorial is designed for testing professionals such as developers, analysts, and testers who are intending to learn the fundamentals http://maiki-tut.ru/default6898.htm of Cucumber and want to put it into practice. Cucumber test cases are written parallel with the code development of software. These test cases are called step in a Gherkin Language. But now, Cucumber supports a variety of different programming languages including Java, JavaScript, PHP, Net, Python, Perl, etc. with various implementations.
This makes it easier to reuse the code, speed up the testing process, and get the finished software product to market. The primary purpose of Cucumber testing is to help teams communicate better about the behavior of an application. By writing tests in a shared language, everyone on the team can understand them. This helps avoid misunderstandings and reduces the need for lengthy discussions about the code. In this post, we’ll look at Cucumber Framework and how it can help you and your team build better products. Cucumber tool plays a vital role in the development of acceptance test cases for automation testing.
To do this, select the Create Suite menu item, and in the window that opens – Create Test. You can create tests one at a time or use the Bulk function and write all the tests you need at once. The advantage of this approach is that Gherkin syntax is understandable to all team members, including specialists without technical knowledge e.g., Product Owner or Business Analyst. This meets one of the basic needs of modern Agile teams – technical and business team collaboration during the testing and development of digital solutions.
Collaboration Bridge the gap between business and technical people by collaborating on executable specifications.
This will help ensure that your tests are easy to understand and maintain. In this report, you can see which scenarios passed and which scenarios failed. You can also see the steps that were executed for each scenario. You can also use other tools to help write and run your Cucumber tests. For example, you can use a tool like Cucumber Studio to help manage your project’s Cucumber tests.
