Getting started with Cucumber in Java A 10 minute tutorial by Marit van Dijk

Automation Testing accelerates the software development lifecycle. Update your class to implement the step definition. We now have one undefined scenario and three undefined steps. Luckily, Cucumber has given us examples, or snippets, that we can use to define the steps. In this file, we integrated Cucumber with BDD framework in Selenium. The code of developed software must correspond with the BDD defined test scripts.

In order for Cucumber to understand the scenarios, they must follow some basic syntax rules, called Gherkin. The step ‘today is Sunday’ and 2 other step are undefined. Cucumber does not execute this line because it’s documentation.

Cucumber vs Selenium vs ALM

This is possible due to its ability to accommodate a wide range of stakeholders and create acceptance test cases most intuitively. After translating your business needs into clear, concise sentences, you can go through the files of test scenarios and see what the product owners need. They, in turn, will be able to make modifications and enhancements. This means that the business analysts can take the scenarios and turn them into testable requirements. Cucumber testing tool is a framework whose goal is to help unify the development, testing, and documentation of feature specifications for engineers, testers, and analysts alike. In this post, we’ll look at Cucumber Framework and how it can help you and your team build better products.

This is precisely what also makes it an end-to-end testing option, especially for complex projects. It can be used not just for the user interface but also for the non-UI parts of your project. Essentially, this means that Gherkin helps construct a standard, understandable test script.


The above command will run only those scenarios that contain the word ‘logout’. Cucumber comes with a built-in command line interface that covers a comprehensive list of instructions. Like most command line tools, cucumber provides the –help option that provides a summary of arguments the command accepts. Syntax is centered around a line-oriented design, similar to that of Python. The structure of a file is defined using whitespace and other control characters.

Mention what has to be done at each step under the relevant method. You will be prompted to restart eclipse after installation. Representational State Transfer in short-form as REST defines a set of constraints for creating Web Services. Rest API is the most-used web service technology nowadays, and it’s an almost meaningless description. A REST API is a way to communicate for two computer systems over HTTP, which is similar to web browsers and servers. Following that, we will start focusing on the advanced level concepts like sharing states and dependency injection.

Set options from the command line using “-Dcucumber.options” – it will work for any java or mvn command. To see all available options, set the options to “–help”, or check the official Cucumber-JVM doc page. Page objects, file readers, and data processors also count as support classes. Test machines must have the Java Development Kit installed to build and run Cucumber-JVM tests. They should also have the desired build tool installed .

  • Most of the organizations use Selenium for functional testing.
  • Below output gets repeated for the number of data sets, i.e., 3 sets.
  • Затем.ЗатемsAllows the use of multiple ‘Затем’s on a single method.
  • They provide features for linking steps to definitions, generating definition stubs, and running tests with various options.
  • But, it can increase complexity by working against succinctly conveying what needs to be conveyed.

But, it can increase complexity by working against succinctly conveying what needs to be conveyed. For something very specific, the generic Gherkin language can be cumbersome and superfluous. Additionally, it accrues technical disadvantages when working with text editors because they don’t read its syntax as a regular language.

To make this step compile we also need to implement a class Belly with a method eat(). As we can see, our tests have run, but have not actually done anything — because they are not yet defined. You can do so by right-clicking the class file and selecting RunCucumberTest from the context menu. Open the project in your IDE and right-click on the src/test/resources/ folder. To make sure everything works together correctly, open a terminal and navigate to your project directory (the one containing the pom.xml file) and enter mvn clean test. Below is the screenshot of the ‘’ script and project tree, how it looks like.
