Allure Reporter
A WebdriverIO reporter plugin to create Allure Test Reports.

Installation
The easiest way is to keep @wdio/allure-reporter as a devDependency in your package.json.
{
  "devDependencies": {
    "@wdio/allure-reporter": "^5.0.0"
  }
}
You can simple do it by:
npm install @wdio/allure-reporter --save-dev
Configuration
Configure the output directory in your wdio.conf.js file:
exports.config = {
    // ...
    reporters: [['allure', {
        outputDir: 'allure-results',
        disableWebdriverStepsReporting: true,
        disableWebdriverScreenshotsReporting: true,
    }]],
    // ...
}
- outputDirdefaults to- ./allure-results. After a test run is complete, you will find that this directory has been populated with an- .xmlfile for each spec, plus a number of- .txtand- .pngfiles and other attachments.
- disableWebdriverStepsReporting- optional parameter(- falseby default), in order to log only custom steps to the reporter.
- issueLinkTemplate- optional parameter, in order to specify the issue link pattern. Reporter will replace- {}placeholder with value specified in- addIssue(value)call parameter. Example- https://example.org/issue/{}
- tmsLinkTemplate- optional parameter, in order to specify the tms link pattern. Reporter will replace- {}placeholder with value specified in- addTestId(value)call parameter. Example- https://example.org/tms/{}
- disableWebdriverScreenshotsReporting- optional parameter(- falseby default), in order to not attach screenshots to the reporter.
- useCucumberStepReporter- optional parameter (- falseby default), set it to true in order to change the report hierarchy when using cucumber. Try it for yourself and see how it looks.
- disableMochaHooks- optional parameter (- falseby default), set it to true in order to not fetch the- before/afterstacktrace/screenshot/result hooks into the Allure Reporter.
- addConsoleLogs- optional parameter(- falseby default), set to true in order to attach console logs from step to the reporter.

Usage
Allure Api can be accessed using:
ES5
const allureReporter = require('@wdio/allure-reporter').default
ES6
import allureReporter from '@wdio/allure-reporter'
Mocha example
describe('Suite', () => {
    it('Case', () => {
        allureReporter.addFeature('Feature')
    })
})
Displaying the report
The results can be consumed by any of the reporting tools offered by Allure. For example:
Command-line
Install the Allure command-line tool, and process the results directory:
allure generate [allure_output_dir] && allure open
This will generate a report (by default in ./allure-report), and open it in your browser.
Autogenerate Report
You can also auto generate the report by using the Allure command line tool programmatically. To do so install the package in your project by:
npm i allure-commandline
Then add or extend your onComplete hook or create a custom service for this:
// wdio.conf.js
const allure = require('allure-commandline')
exports.config = {
    // ...
    onComplete: function() {
        const reportError = new Error('Could not generate Allure report')
        const generation = allure(['generate', 'allure-results', '--clean'])
        return new Promise((resolve, reject) => {
            const generationTimeout = setTimeout(
                () => reject(reportError),
                5000)
            generation.on('exit', function(exitCode) {
                clearTimeout(generationTimeout)
                if (exitCode !== 0) {
                    return reject(reportError)
                }
                console.log('Allure report successfully generated')
                resolve()
            })
        })
    }
    // ...
}
Jenkins
Install and configure the Allure Jenkins plugin
Add Screenshots
Screenshots can be attached to the report by using the takeScreenshot function from WebDriverIO in the afterStep hook.
First set disableWebdriverScreenshotsReporting: false in reporter options, then add in afterStep hook:
afterStep: function (test, scenario, { error, duration, passed }) {
  if (error) {
    browser.takeScreenshot();
  }
}
As shown in the example above, when this function is called, a screenshot image will be attached to the allure report.
