Updating Cypress Tests to Output in JUnit XML Format

In this article, we'll walk through the steps to update your Cypress tests to output in JUnit XML format and how to upload them to Testery for automated analysis.

Prerequisites

Before we get started, ensure you have the following prerequisites in place:

1. Cypress Installed: You should have Cypress installed in your project. If it's not already installed, you can do so by running npm install cypress --save-dev.

2. Node.js: Make sure you have Node.js installed on your machine.

3. A Cypress Test Suite: You should have a Cypress test suite already set up and running.

4. Testery CLI. You should have the Testery CLI installed. If you don't have it already, run pip install testery.

Step 1: Install Cypress JUnit Reporter

To generate JUnit XML reports, we'll need to install the cypress-junit-reporter package. This package provides a custom reporter for Cypress that converts test results into JUnit XML format.

Open your project's terminal and run the following command to install the package:

npm install cypress-junit-reporter --save-dev

Step 2: Update Your Cypress Configuration

Now that you have the JUnit reporter installed, you need to update your Cypress configuration to use it.

1. Open your Cypress configuration file, usually named cypress.json.

2. Add a "reporter" option to specify the reporter you want to use. Set it to "junit":

{
  "reporter": "junit"
}

1. Optionally, you can also configure the reporter with additional options. For example, you can specify the output folder for the JUnit XML files:

{
  "reporter": "junit",
  "reporterOptions": {
    "mochaFile": "cypress/reports/junit/test-results.xml"
  }
}

This configuration will save the JUnit XML reports in a cypress/reports/junit folder with filenames that include a hash to ensure uniqueness.

Step 3: Run Your Cypress Tests

Now that your Cypress configuration is updated, you can run your Cypress tests as usual. Cypress will automatically use the JUnit reporter to generate XML reports.

To run your tests, use the following command:

npx cypress run

After running the tests, you should see JUnit XML files generated in the specified output folder.

Step 4: Upload Your Test Results to Testery

The final step is to upload the generated JUnit XML files into your CI/CD pipeline. The specific steps for doing this will depend on your CI/CD platform. Here's a general outline of what you'll need to do:

testery upload-results \
  --environment develop \
  --project name \
  --file cypress/reports/junit/test-results.xml
