The Cypress plugin cypress-cucumber-preprocessor helps you write your end-to-end tests using Cucumber syntax, bridging the gap between behavior-driven development (BDD) and modern web testing frameworks. This approach allows you to write tests in the human-readable Gherkin format, enhancing communication between stakeholders, developers, and testers.
How does Cypress Cucumber Preprocessor Work?
The Cucumber preprocessor acts as an interpreter between Cucumber’s feature files and Cypress. It translates human-readable Gherkin syntax (Given-When-Then scenarios) into executable JavaScript code for Cypress. This behind-the-scenes process maintains Cucumber’s clarity while leveraging Cypress’s powerful browser automation capabilities. As developers and testers, we know that writing expressive tests is crucial, but optimizing test execution is equally important.
This is where HyperExecute comes in. It’s an AI-powered test orchestration cloud platform designed for speed and scalability. HyperExecute enables parallel execution of Cypress Cucumber tests across multiple environments, significantly reducing overall execution time.
In this blog post, we’ll guide you on how you can execute these tests efficiently on HyperExecute at unprecedented speeds and with a streamlined workflow setup.
Steps to execute your Cypress tests on HyperExecute
Prerequisites
- Node.js and npm
- Basic knowledge of Cypress and Cucumber
- Cypress version >= 10
- Create your free LambdaTest account
- Your LambdaTest Username and Access Key
Setting up the Project
Below are the steps to set your cypress project for execution in the HyperExecute platform
- Step 1: Create a folder and generate package.json.
- Create a project, naming it cypress-cucumber-preprocessor.
- Use the npm init command to create a package.json file
- Step 2: Write your testing scenarios in Gherkin syntax
- Create a folder named cypress > e2e
- Define your feature files
- Write the corresponding step definition
- Step 3: Download the HyperExeute CLI
- HyperExecute CLI is a command line interface that lets you trigger your tests on the HyperExecute platform.
- Download the CLI as per your respective operating system in the root folder of your project.
- Step 4: Create your HyperExecute YAML file.
- runson: In this flag, define the operating system where you want to spin up your test
- pre: In this flag, we pass all the commands required to run your test. In this case,

| Operating System | HyperExecute CLI Download URL |
|---|---|
| Linux | https://downloads.lambdatest.com/hyperexecute/linux/hyperexecute |
| Windows | https://downloads.lambdatest.com/hyperexecute/windows/hyperexecute.exe |
| macOS | https://downloads.lambdatest.com/hyperexecute/darwin/hyperexecute |
The YAML file allows you to define the configurations required for executing your tests on HyperExecute.
A sample YAML file is shown below for your reference:

NOTE: In the case of macOS, if you get a permission denied warning while executing CLI, simply run chmod u+x ./hyperexecute to allow permission. If you get a security popup, allow it from your System Preferences → Security & Privacy → General tab.
Run the below command in your terminal at the root folder of the project:
|

./hyperexecute --user YOUR_USERNAME --key YOUR_ACCESS_KEY --config RELATIVE_PATH_OF_YOUR_YAML_FILE |
Conclusion
Integrating Cypress Cucumber Preprocessor with HyperExecute provides an efficient and scalable BDD testing solution. This setup offers you:
- Enhanced readability through Gherkin syntax
- Improved team collaboration
- Robust automation with Cypress
- Scalability and speed via HyperExecute’s parallel execution
- A streamlined workflow for test setup and execution
This approach maintains BDD clarity while leveraging modern testing tools and cloud infrastructure. As your project grows, this flexible setup can adapt to your needs, whether you’re working on a small application or a large-scale project.
You can further explore this setup by integrating it into your CI/CD pipeline or expanding your test coverage. This foundation equips you to enhance your automated testing efforts and build more reliable software.
