mocha-ctrf-json-reporter

Mocha JSON Reporter

A Mocha 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.

Features

• Generate JSON test reports that are CTRF compliant
• Straightforward integration with Mocha

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 mocha-ctrf-json-reporter

You can configure Mocha to use mocha-ctrf-json-reporter in several ways: through .mocharc.js, .mocharc.json, or via the command line. Below are the instructions for each method:

Update your .mocharc.js file as follows:

module.exports = {
  reporter: 'mocha-ctrf-json-reporter',
}

Using .mocharc.json, update your config file as follows:

{
  "reporter": "mocha-ctrf-json-reporter"
}

Run your tests as you normally would:

npx mocha

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

You can also specify the reporter from the command line:

mocha --reporter mocha-ctrf-json-reporter

Reporter Options

The reporter supports several configuration options, update your .mocharc.js

{
  reporter: "mocha-ctrf-json-reporter",
  reporterOptions: {
    outputFile: 'custom-name.json', // Optional: Output file name. Defaults to 'ctrf-report.json'.
    outputDir: 'custom-directory',  // Optional: Output directory path. Defaults to 'ctrf'.
    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.
  }
},

For .mocharc.json

{
  "reporter": "mocha-ctrf-json-reporter",
  "reporterOptions": {
    "outputFile": "custom-name.json"
  }
}

Alternatively, you can pass the reporter options via the command line when running your Mocha tests. Use the --reporter-options flag followed by the options in a key=value format, separated by commas:

npx mocha --reporter mocha-ctrf-json-reporter --reporter-options "outputFile=custom-name.json,outputDir=custom-directory,appName=MyApp,appVersion=1.0.0"
