How do I add dependency injection to a cucumber test?
Adding dependency injection to Cucumber tests The piece of code that brings dependency injection to our Cucumber tests is the CucumberSpringConfiguration class. The @CucumberContextConfiguration annotation tells Cucumber to use this class as the test context configuration for Spring.
How to use picocontainer with BDD cucumber?
In BDD Cucumber, we can use this technique by simply adding a dependency in our POM.XML file. And the name of that dependency is “Cucumber-Picocontainer” Important: Cucumber Version and Picocontainer version must be the same.
Is it possible to use inheritance in cucumber?
Cucumber does not support inheritance, so interfaces or Dependency Injection (Pico Container) is the way to go. I do not know how to do this, and I have studied online, I just cannot wrap my poor brain around it all.
How to do dependency injection in selenium with WebDriver?
At the initial step, you need to add the following dependency. There are three main classes which are involved in the dependency injection. Here we introduce them one by one. BaseUtil is the class which has an attribute for WebDriverof Selenium. The class is quite simple: The Hook class contains @Before, @After.
What is dependency injection in BDD?
Dependency injection (DI) is one of the design patterns and implementations of the IoC. DI takes the dependent object creation outside of the class and provides required objects in different ways. Using DI, you move the creation and binding of the dependent objects outside of the class that depends on them.

What is feature file in Cucumber?
A Feature File is an entry point to the Cucumber tests. This is a file where you will describe your tests in Descriptive language (Like English). It is an essential part of Cucumber, as it serves as an automation test script as well as live documents.
What is TestContext in Cucumber?
Scenario Context in Cucumber Just to keep things simple, we can say that the TestContext is the parent class and the medium to share the information between the different steps in a test. It can have many class objects in it.
What are Cucumber hooks?
Hooks. Hooks are blocks of code that can run at various points in the Cucumber execution cycle. They are typically used for setup and teardown of the environment before and after each scenario. Where a hook is defined has no impact on what scenarios or steps it is run for.
What is scenario Context in Cucumber?
Scenario Context class holds the test data information explicitly. It helps you store values in a key-value pair between the steps. Moreover, it helps in organizing step definitions better rather than using private variables in step definition classes.

Organize Your Test Steps
Keep it DRY, “Don’t Repeat Yourself.” You’ll hear this a lot when writing code, and guess what, your glue code is code! So, what does this mean for our Cucumber tests? Ensuring you have one test step for each action that you are trying to accomplish, and that the information contained within, has the appropriate flexibility.
What is a Dependency Injector
At their core, Dependency Injectors (DIs) are about being able to extend an object’s behavior at runtime by injecting business logic. While this allows you to do a lot of awesome things, for this post, we’re going to discuss one particular capability that DIs allow: passing objects from one class to another, instead of hardcoding values or steps.
The Spring Boot sample project
Updated (Feb 17th, 2021): This guide uses now Cucumber 6. If you want to check the changes needed to upgrade from Cucumber Spring version 4 to 6, have a look at the Pull Request
Required Libraries
We want to use Dependency Injection in our tests with Spring, so we’ll add the cucumber-spring dependency on top of the common cucumber-java and cucumber-junit, needed when you want to write Cucumber tests with Java and JUnit.
How Cucumber-Spring works
The key part of this post: how to make DI work with Spring Boot? It’s simple but not really intuitive. Let’s see the steps.
State
It’s important to prevent state created by one scenario from leaking into others. Leaking state makes your scenarios brittle, and difficult to run in isolation.
How to use DI
When using a DI framework all your step definitions, hooks, transformers, etc. will be created by the frameworks instance injector.
Databases
There are several options to remove state from your database, to prevent leaking state between scenarios.
Browser Automation and Transactions
If you’re using a browser automation tool that talks to your application over HTTP, the transactional approach will not work if your step definitions and the web application serving HTTP request each have their own database connection.

Required Libraries
- We want to use Dependency Injection in our tests with Spring, so we’ll add the cucumber-spring dependency on top of the common cucumber-java and cucumber-junit, needed when you want to write Cucumber tests with Java and JUnit. As you see in the pom.xmlfile, this post has been updated to use Cucumber 6.8.
How cucumber-spring Works
- Overview
The key part of this post: how to make DI work with Spring Boot? It’s simple but not really intuitive. Let’s see the steps. Even though the sample application has only one controller, BagController, I split the tests into two different Cucumber Features in a way they also make use of two separat… - Entry Point: @RunWith Cucumber
First, let’s have a simple class to configure each Cucumber test. This is just a shell that serves as an entry point for the test, together with its configuration. We’ll annotate it with @RunWith(Cucumber.class)to instruct JUnit to use this runner so we have all the Cucumber fun…
Running The Application
- You can now run the tests from your favorite IDE or using Maven: You’ll see how Cucumber prints the steps and the logs in between them: That will only happen if you set the plugin “pretty” in @CucumberOptions (like we did in this example). Since we also set the option to generate HTML reports, we’ll have them available in the target/cucumberfolder. Don’t expect fancy reports, it’s ve…
