cucumber-playwright

A starter repo for writing E2E tests based on Cucumber(7) with Playwright using Typescript.

The Why

Read or watch.

Can we use XXX from playwright in the playwright-cucumber project?

The playwright-cucumber project started when playwright was a browser automation library. It did not have a test runner, hence cucumber-js was used as the test runner and PW used for the automation. Since then PW added their amazing PW test library which is a test runner. But, sadly, it overlaps the functionality provided by cucumber-js. Therefore you need to make the decision now of which runner you want to run: cucumber for BDD style tests or PW test for “normal” tests. Some of the features provided by PW test are also available in cucumber-js, such as parallel run and different configurations (profiles in cucumber-js terms), but may require a different configuration.

Kudos

This repository is based on the Cucumber-typescript-starter repo.

What's inside

• Typescript setup for writing steps with eslint/typescript and prettier
• Launching of Playwright browser before running all tests
• Launching new context and page for each scenario
• Running feature with video recording option
• Report generated with last good image attached
• Allure reports
• Utilies function to help you with writing steps
• VScode configuration to debug a single feature or an only scenario (run when located on the feature file)

Usage

Create a repo based on this template and start writing your tests.

To run your tests

npm run test or npx cucumber-js runs all tests npm run test <feature name> or npx cucumber-js <feature name> run the single feature

Browser selection

By default we will use chromium. You can define an envrionment variable called BROWSER and set the name of the browser. Available options: chromium, firefox, webkit

On Linux and Mac you can write:

BROWSER=firefox npm run test or BROWSER=firefox npx cucumber-js runs all tests using Firefox

One Windows you need to write

set BROWSER=firefox
npm run test

Working with Page Objects

I am not fond of the Page Object Model (POM) for testing. It feels like a leftover from Java world, and I do not think it fits the Javascript world. However, you can check this PR to see POM implementation.

Debugging Features

From CLI

• npm run debug - headful mode with APIs enables both APIs and debug options
• npm run api - headless mode with debug apis
• npm run video - headless mode vith video

In Visual Studio Code

• Open the feature
• Select the debug options in the VSCode debugger
• Set breakpoints in the code

To stop the feature, you can add the Then debug step inside your feature. It will stop your debugger.

To choose a reporter

The last reporter/formatter found on the cucumber-js command-line wins:

--format summary --format @cucumber/pretty-formatter --format cucumber-console-formatter

In cucumber.mjs file, modify the options.

To use Allure reporting, you can run with env param: USE_ALLURE=1, and then use the npm run allure to show the report.

To ignore a scenario

• tag the scenario with @ignore

To check for typescript, linting and gherkin errors

• run the command npm run build.

To view the steps usage

• run the command npm run steps-usage.

To view the html report of the last run

• run the command npm run report.

At least in Lubuntu 20.04 to open the html report

• Modify the package.json in "report": "xdg-open reports/report.html"

To view allure report

• run the command npm run allure.
