JSON TestCafé Reporter

This is the JSON reporter plugin for TestCafé.

This TestCafé reporter generates JSON files that can be merged and converted to a nice and searchable html report by using multiple-cucumber-html-reporter.

JSON files generated by this reporter have the same schema than those generated by the Cucumber JSON reporter: this is why fixture is translated to Feature and test to Scenario in the final HTML report.

To install this TestCafé Reporter

• run the command:

  npm install --save testcafe-reporter-cucumber-json

Usage

• add to the TestCafé command-line the following options:

  testcafe chrome ./path-to-tests/*(.js|.testcafe|.ts) --reporter cucumber-json

JSON files will be automatically created in a folder named cucumber-json-reports at the root of your project.

If you need to change this folder, add this option on the TestCafé command-line:

--reporter-json-folder='my-custom-folder'

or add/edit the args section inside the testcafe-reporter-cucumber-json.json configuration file:

  "args": {
    "reportFolder": "my-custom-folder"
  }

or set the environment variable --reporter-json-folder (in this case this variable will take precedence over the command-line option and the configuration file):

process.env['--reporter-json-folder'] = 'my-custom-folder';

At each TestCafé run, this reporter will create a separate JSON file for each browser started by TestCafé.

Each JSON file will be named : [browser name][browser platform][date and time of execution].json.

Examples:

  cucumber-json-reports
  |- Chrome_83_0_4103_116_macOS_10_15_5-2020-07-04T19-44-58-493Z.json
  |- Firefox_78_0_macOS_10_15-2020-07-04T19-44-58-493Z.json
  |- Microsoft_Edge_83_0_478_58_macOS_10_15_5-2020-07-04T19-38-05-688Z.json
  |- Microsoft_Edge_83_0_478_58_macOS_10_15_5-2020-07-04T19-44-58-493Z.json
  |- Safari_13_1_1_macOS_10_15_5-2020-07-04T19-44-58-493Z.json
  |- ...

If you would like to show in the report the App name targeted by your tests, add this option on the TestCafé command-line:

--reporter-app-name='My App'

or add/edit the args section inside the testcafe-reporter-cucumber-json.json configuration file:

  "args": {
    "appName": "My App",
  }

or set the environment variable --reporter-app-name (in this case this variable will take precedence over the command-line option and the configuration file):

process.env['--reporter-app-name'] = 'My App';

And if you need to also show the App version, add this option on the TestCafé command-line:

--reporter-app-version='x.y.z'

or add/edit the args section inside the testcafe-reporter-cucumber-json.json configuration file:

  "args": {
    "appVersion": "x.y.z",
  }

or set the environment variable --reporter-app-version (in this case this variable will take precedence over the command-line option and the configuration file):

process.env['--reporter-app-version'] = 'x.y.z';

To generate the HTML report

The HTML report will merge all the JSON files inside folder cucumber-json-reports into a single HTML file.

• install multiple-cucumber-html-reporter:

  npm install --save-dev multiple-cucumber-html-reporter (>= v1.18.0)

• Create a report-generator.js file at the project root:

  const report = require('multiple-cucumber-html-reporter');
  const path = require('path');
  const projectName = path.basename(__dirname);
  const projectVersion = process.env.npm_package_version;
  const reportGenerationTime = new Date().toISOString();
  report.generate({
    reportName: 'TestCafé Report',
    jsonDir: 'cucumber-json-reports',
    reportPath: 'cucumber-json-reports/html',
    openReportInBrowser: true,
    disableLog: true,
    displayDuration: true,
    displayReportTime: true,
    durationInMS: true,
    customData: {
      title: 'Run info',
      data: [
        { label: 'Project', value: `${projectName}` },
        { label: 'Release', value: `${projectVersion}` },
        { label: 'Report Generation Time', value: `${reportGenerationTime}` },
      ],
    },
  });

• insert the following script in the package.json file:

  "report": "node report-generator.js",

• run the command npm run report

Tagging

• Tags enables to filter the html report;
• Tags are generated dynamically from the:
  • fixture description
  • test description
  • fixture file name (TBD)
  • fixture folder hierarchy (TBD)
  • new t.meta() syntax (TBD)

Tags managment

• Tags can be managed through the configuration file testcafe-reporter-cucumber-json.json
  • this json file will be created on the first reporter run
• To discard a tag, add this tag to the noisyTags section of the json configuration file.

Error rendering

• this reporter will report multiple code frames, one for each file reported in the stacktrace

1) The specified selector does not match any element in the DOM tree.
