Hello guys, In this video, we will explore how to use cucumber with TypeScript. Cucumber is a popular behavior-driven development (BDD) tool that allows developers and stakeholders to collaborate on defining and testing application requirements in a human-readable format. TypeScript is a powerful superset of JavaScript that adds optional static typing, making it easier to catch errors before runtime. By combining these two tools, we can create more reliable and maintainable tests.
In this tutorial, we learn how to integrate Playwright with Cucumber for test automation. The main steps involved in this integration are:
Setup project structure: In the project root, create a folder structure like SRC/test/features
for keeping all the feature files and a folder named steps
for keeping all the step definitions.
Create feature file: Create a feature file named login.feature
inside the features folder. This file contains our test scenarios written in the Cucumber Gherkin language that describe the expected behavior of our application.
Configure Cucumber: Create a cucumber.json
file in the project root to store the Cucumber configuration options. In this file, specify the path to the feature files and the step definitions.
Update package.json
: Add a script named test
in the package.json file with the command cucumber-js/test
, which will be used to run our test scenarios.
Implement step definitions: Create a TypeScript file named loginStep.ts
inside the steps folder, and implement the step definitions by importing the necessary dependencies from the @cucumber/cucumber
package. Make sure to use async and await syntax while writing the step definitions.
Configure VSCode settings: To resolve any issues with displaying undefined steps in the feature file, update the Cucumber settings in the VSCode user settings file by specifying the correct paths to the feature files and step definition files.
Run the test scenarios: Finally, run the test scenarios using the command npm test
in the terminal. This will execute the test scenarios specified in the login.feature
file using Playwright and Cucumber.
By following these steps, you can successfully integrate Playwright with Cucumber to create robust and maintainable test automation scripts in TypeScript.
