Cypress JSON Test Results Report

Save Cypress test results as a JSON file

A Cypress JSON test reporter to create test reports that follow the CTRF standard.

Common Test Report Format ensures the generation of uniform JSON test reports, independent of programming languages or test framework in use.

What is CTRF?

CTRF is a universal JSON test report schema that addresses the lack of a standardized format for JSON test reports.

Consistency Across Tools: Different testing tools and frameworks often produce reports in varied formats. CTRF ensures a uniform structure, making it easier to understand and compare reports, regardless of the testing tool used.

Language and Framework Agnostic: It provides a universal reporting schema that works seamlessly with any programming language and testing framework.

Facilitates Better Analysis: With a standardized format, programatically analyzing test outcomes across multiple platforms becomes more straightforward.

Installation

npm install --save-dev cypress-ctrf-json-reporter

Add the reporter to your cypress.config.js/ts file:

const { defineConfig } = require('cypress')
const { GenerateCtrfReport } = require('cypress-ctrf-json-reporter')

module.exports = defineConfig({
  e2e: {
    setupNodeEvents(on, config) {
      // Implement node event listeners here
      new GenerateCtrfReport({
        on,
      })
    },
  },
})

Run your tests:

npx cypress run

You'll find a JSON file named ctrf-report.json in the ctrf directory.

Installation for Cypress versions below v10

Add the reporter to your cypress/plugins/index.js/ts

const { GenerateCtrfReport } = require('cypress-ctrf-json-reporter')

/// <reference types="cypress" />

/**
 * @type {Cypress.PluginConfig}
 */
// eslint-disable-next-line no-unused-vars
module.exports = (on, config) => {
  new GenerateCtrfReport({
    on,
  })
}

Reporter Options

The reporter supports several configuration options:

new GenerateCtrfReport({
  on,
  outputFile: 'custom-name.json', // Optional: Output file name. Defaults to 'ctrf-report.json'.
  outputDir: 'custom-directory', // Optional: Output directory path. Defaults to 'ctrf'.
  minimal: true, // Optional: Generate a minimal report. Defaults to 'false'. Overrides screenshot and testType when set to true
  testType: 'e2e', // Optional: Specify the test type (e.g., 'api', 'e2e'). Defaults to 'e2e'.
  appName: 'MyApp', // Optional: Specify the name of the application under test.
  appVersion: '1.0.0', // Optional: Specify the version of the application under test.
  osPlatform: 'linux', // Optional: Specify the OS platform.
  osRelease: '18.04', // Optional: Specify the OS release version.
  osVersion: '5.4.0', // Optional: Specify the OS version.
  buildName: 'MyApp Build', // Optional: Specify the build name.
  buildNumber: '100', // Optional: Specify the build number.
  buildUrl: 'https://ctrf.io', // Optional: Specify the build url.
  repositoryName: 'ctrf-json', // Optional: Specify the repository name.
  repositoryUrl: 'https://gh.io', // Optional: Specify the repository url.
  branchName: 'main', // Optional: Specify the branch name.
  testEnvironment: 'staging', // Optional: Specify the test environment (e.g. staging, production).
})

Handling Multiple Plugins in Cypress

Cypress's plugin system allows you to extend its functionality by adding event listeners to various lifecycle events like before:run, after:run, etc. However, a limitation in the Cypress plugin system is that it only supports one listener per event. This means that if you register multiple plugins that listen to the same event, the last registered plugin will override any previous ones.

This can cause issues when using multiple reporting plugins with cypress-ctrf-json-reporter as only one of them will actually execute its event handler.

To overcome this limitation, you can use a custom function to manage multiple event listeners for the same event, ensuring that all plugins work together seamlessly.

Follow the steps below to ensure that cypress-ctrf-json-reporter and other plugins work together without conflict.

Step 1: Create a Custom initPlugins Function

In your Cypress configuration file (usually cypress.config.js), create a utility function to handle multiple plugins:

function initPlugins(on, plugins) {
  const eventCallbacks = {}

  const customOn = (eventName, callback) => {
    if (!eventCallbacks[eventName]) {
      eventCallbacks[eventName] = []
      // Register a single handler for each event that will execute all registered callbacks
      on(eventName, async (...args) => {
        for (const cb of eventCallbacks[eventName]) {
          await cb(...args)
        }
      })
    }
    eventCallbacks[eventName].push(callback)
  }

  // Initialize each plugin with the custom `on` handler
  plugins.forEach((plugin) => plugin(customOn))
}

This function ensures that multiple event listeners for the same event are preserved and called in sequence, allowing multiple plugins to function together.

Step 2: Modify Your Cypress Configuration

Use the initPlugins function to initialize your plugins, including cypress-ctrf-json-reporter. Here is an example using CTRF and the popular mochaawesome plugin:

const { defineConfig } = require('cypress')
const { GenerateCtrfReport } = require('cypress-ctrf-json-reporter')
const mochawesome = require('cypress-mochawesome-reporter/plugin')

module.exports = defineConfig({
  reporter: 'cypress-mochawesome-reporter',
  e2e: {
    setupNodeEvents(on, config) {
      // Initialize both plugins with the custom `on` handler
      initPlugins(on, [
        (on) => mochawesome(on),
        (on) => new GenerateCtrfReport({ on }),
      ])
    },
  },
})

Test Object Properties

The test object in the report includes the following CTRF properties:

Name	Type	Required	Details
name	String	Required	The name of the test.
status	String	Required	The outcome of the test. One of: passed, failed, skipped, pending, other.
duration	Number	Required	The time taken for the test execution, in milliseconds.
message	String	Optional	The failure message if the test failed.
trace	String	Optional	The stack trace captured if the test failed.
rawStatus	String	Optional	The original cypress status of the test before mapping to CTRF status.
type	String	Optional	The type of test (e.g., api, e2e).
filepath	String	Optional	The file path where the test is located in the project.
retries	Number	Optional	The number of retries attempted for the test.
flaky	Boolean	Optional	Indicates whether the test result is flaky.
browser	String	Optional	The browser used for the test.
