Generates test results in the json formated needed to create Mochawesome reports.

There are breaking changes between WDIO v4 and v5 with how custom reporters work. The chart below shows the versions of this reporter and their WDIO compatibility version.

• NPM

npm install wdio-mochawesome-reporter --save-dev

• Yarn

yarn add wdio-mochawesome-reporter --dev

reporters: [
  'dot',
  ['mochawesome',{ stdout: true }]
],

reporters: [
  'dot',
  ['mochawesome',{
      outputDir: './Results'
  }]
],

reporters: [
  'dot',
  ['mochawesome',{
    outputDir: './Results',
    outputFileFormat: function(opts) { 
        return `results-${opts.cid}.${opts.capabilities}.json`
    }
  }]
],

With WDIO v5, 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 we are no longer able to get a single report for ALL test execution. Consider the following:

2 suites of tests configured to run in 2 browsers:

• WDIO v4: 1 json file with execution results
• WDIO v5: 4 json files with execution results

wdio-mochawesome-reporter provides a utility function to merge the multiple json files into a single file. You can Follow the steps below to take advantage of the utility.

1. Create a small node script

const mergeResults = require('wdio-mochawesome-reporter/mergeResults')
mergeResults()

2. Call node script from command line and pass 2 arguments

• <RESULTS_DIR>: Directory where results files are written
• <FILE_REGEX>: Regex pattern for finding wdio-mochawesome-reporter result files in <RESULTS_DIR>. This is necessary because multiple reporters produce json result files

Example:

node mergeResults.js ./Results "wdio-mochawesome-*"

The onComplete is a great place to call the mergeResults script. Usage this way requires passing in the results directory and the file pattern as arguments to the script.

// Located in your wdio.conf.js file
onComplete: function (exitCode, config, capabilities, results) {
  const mergeResults = require('wdio-mochawesome-reporter/mergeResults')
  mergeResults('./Results', "results-*")
}

Upon completion, the merge script will output a single json file named wdio-ma-merged.json in the provided <RESULTS_DIR>

• NPM

npm install wdio-mochawesome-reporter@^2.0.1 --save 

• Yarn

yarn add wdio-mochawesome-reporter@^2.0.1 --dev

Add mochawesome to the reporters array in your wdio config file.

// sample wdio.conf.js
module.exports = {
  // ...
  reporters: ['dot', 'mochawesome'],
  // ...
};

The following configuration options are supported:

To use a configuration option add a mochawesomeOpts section to your wdio config. Then add any options.

// sample wdio.conf.js
module.exports = {
  // ...
  reporters: ['dot', 'mochawesome'],
  mochawesomeOpts: {
      includeScreenshots:true,
      screenshotUseRelativePath:true
  },
  // ...
};

To convert the json generated by this package into a Mochawesome report you will need to use the Mochawesome Report Generator.

In summary...

• Add the package to your project

yarn add mochawesome-report-generator --dev

• Add a script to your package.json to generate the report

  "scripts": {
    "generateMochawesome":"marge path/to/results.json --reportTitle 'My Project Results'"
  },

1. path/to/results.json = path and name of json file
2. --reportTitle 'My Project Results' = unique report title
