Webdriverio JSON Test Results Report

Save Webdriverio test results as a JSON file

A WDIO 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.

It means a lot to us and helps us grow this open source library.

We need your help

We believe CTRF can save a lot of time for engineers, a single data serialisation report, well structured, community driven and works with any framework. For over 30s years software engineers have used a de facto data serialisation report, you know the one! But we feel it’s time to modernise.

The only way we can grow CTRF is with your help and the support of the software engineering community.

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 wdio-ctrf-json-reporter

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

reporters: [
  ['ctrf-json', {}]],

Run your tests:

npm run wdio

In the ctrf directory, you will find the JSON report files generated for each spec.

Reporter Options

The reporter supports several configuration options:

reporter: [
    ['wdio-ctrf-json-reporter', {
        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.
    }]
  ],

Merge reports

With WDIO v5 upwards, reporting has moved from a centralized process to one that is handled by each of the "sessions" spun up for parallel test execution. This change helped reduce the amount of chatter during WDIO test execution and thus improved performance. The downside is it is no longer possible to get a single report for all test execution.

merge-ctrf package provides a utility to merge the multiple json files into a single file.

After executing your tests, use the following command:

npx merge-ctrf <directory>

Replace directory with the path to the directory containing the CTRF reports you want to merge.

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.
`start`	Number	Optional	The start time of the test as a Unix epoch timestamp.
`stop`	Number	Optional	The end time of the test as a Unix epoch timestamp.
`suite`	String	Optional	The suite or group to which the test belongs.
`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 playwright 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.
