Allure Reporter

A WebdriverIO reporter plugin to create Allure Test Reports.

Installation

The easiest way is to include @wdio/allure-reporter as a devDependency in your package.json.

{
  "devDependencies": {
    "@wdio/allure-reporter": "^7.0.0"
  }
}

You can simply do it by:

npm install @wdio/allure-reporter --save-dev

Configuration

Configure the output directory in your wdio.conf.js file:

export const config = {
    // ...
    reporters: [['allure', {
        outputDir: 'allure-results',
        disableWebdriverStepsReporting: true,
        disableWebdriverScreenshotsReporting: true,
    }]],
    // ...
}

• outputDir defaults to ./allure-results. After a test run is complete, you will find that this directory has been populated with an .xml file for each spec, plus a number of .txt and .png files and other attachments.
• disableWebdriverStepsReporting - optional parameter(false by 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. The same logic is applied if Cucumber is used and tag issue is set at any level, it will be converted to the link in the report. The parameter value example:

  https://example.org/issue/{}
• tmsLinkTemplate - optional parameter, in order to specify TMS (Test Management System) link pattern. Reporter will replace {} placeholder with value specified in addTestId(value) call parameter. The same logic is applied if Cucumber is used and tag testId is set at any level, it will be converted to the link in the report. The parameter value example:

  https://example.org/tms/{}
• disableWebdriverScreenshotsReporting - optional parameter(false by default), in order to not attach screenshots to the reporter.
• useCucumberStepReporter - optional parameter (false by 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 (false by default), set it to true in order to not fetch the before/after stacktrace/screenshot/result hooks into the Allure Reporter.
• addConsoleLogs - optional parameter(false by default), set to true in order to attach console logs from step to the reporter.
• reportedEnvironmentVars (type: Record<string, string>) - Set this option to display the environment variables in the report. Note that setting this, does not modify the actual environment variables.

Supported Allure API

• addLabel(name, value) - assign a custom label to test
• addFeature(featureName) – assign features to test
• addStory(storyName) – assign user story to test
• addSeverity(value) – assign severity to test, accepts one of these values: blocker, critical, normal, minor, trivial
• addTag(value) – assign a tag label to test
• addEpic(value) – assign an epic label to test
• addOwner(value) – assign an owner label to test
• addSuite(value) – assign a suite label to test
• addSubSuite(value) – assign a sub suite label to test
• addParentSuite(value) – assign a parent suite label to test
• addIssue(value) – assign issue id to test
• addAllureId(value) – assign allure test ops id label to test
• addTestId(value) – assign TMS test id to test
• ~~addEnvironment(name, value) ~~ – a deprecated function that no longer works. Use reportedEnvironmentVars instead
• addAttachment(name, content, [type]) – save attachment to test.
  • name (String) - attachment name.
  • content – attachment content.
  • type (String, optional) – attachment MIME-type, text/plain by default
• addArgument(name, value) - add an additional argument to test
• addDescription(description, [type]) – add description to test.
  • description (String) - description of the test.
  • type (String, optional) – description type, text by default. Values ['text', 'html','markdown']
• addStep(title, [{content, name = 'attachment'}], [status]) - add step to test.
  • title (String) - name of the step.
  • content (String, optional) - step attachment
  • name (String, optional) - step attachment name, attachment by default.
  • status (String, optional) - step status, passed by default. Must be "failed", "passed" or "broken"
• startStep(title) - start with a step
  • title (String) - name of the step.
• endStep(status) - end with a step
  • status (String, optional) - step status, passed by default. Must be "failed", "passed" or "broken"
• step(name, body) - starts step with content function inside. Allows to create steps with infinite hierarchy
  • body (Function) - the step body async function

Usage

Allure Api can be accessed using:

CJS

const allureReporter = require('@wdio/allure-reporter').default

ESM

import allureReporter from '@wdio/allure-reporter'

Mocha example

describe('Suite', () => {
    it('Case', () => {
        allureReporter.addFeature('Feature')
    })
})

Cucumber

Basic Cucumber example:

Given('I include feature and story name', () => {
    allureReporter.addFeature('Feature_name');
    allureReporter.addStory('Story_name');
})

Custom steps

step method simplifies dealing with steps because each step present as an async function with any content inside. The first argument of the function is the current step, that has most of the allure API methods (such as label, epic, attach etc):

allureReporter.step('my step name', async (s1) => {
    s1.label('foo', 'bar')
    await s1.step('my child step name', async (s2) => {
        // you can add any combination of steps in the body function
    })
})

Cucumber Tags

Cucumber tags with special names (issue and testId) are converted to the links (the corresponding link templates must be configured before):

@issue=BUG-1
@testId=TST-2
Feature: This is a feature with global tags that will be converted to Allure links

  @issue=BUG-3
  @testId=TST-4
  Scenario: This is a scenario with tags that will be converted to Allure links
    Given I do something

Cucumber tags with special names (feature) are mapped to Allure labels:

Feature: Test user role

  @feature=login
  Scenario: Login
    Given I test login

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')

export const 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 afterTest hook for Mocha and Jasmine or afterStep hook for Cucumber. First set disableWebdriverScreenshotsReporting: false in reporter options, then add in afterStep hook:

Mocha / Jasmine

wdio.conf.js

afterTest: async function(test, context, { error, result, duration, passed, retries }) {
    if (error) {
        await browser.takeScreenshot();
    }
}

Cucumber

wdio.conf.js

afterStep: async function (step, scenario, { error, duration, passed }, context) {
  if (error) {
    await browser.takeScreenshot();
  }
}

As shown in the example above, when this function is called, a screenshot image will be attached to the allure report.
