Allure Reporter

The Allure Reporter creates Allure test reports which is an HTML generated website with all necessary information to debug your test results and take a look on error screenshots. To use it just install it from NPM:

1

$ npm install wdio-allure-reporter --save-dev

Then add allure to the reporters array in your wdio.conf.js and define the output directory of the allure reports:

1

// wdio.conf.js
exports.config = {
    // ...
    reporters: ['dot', 'allure'],
    reporterOptions: {
        allure: {
            outputDir: 'allure-results'
        }
    },
    // ...
}

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.

Displaying the report

The results can be consumed by any of the reporting tools offered by Allure. For example:

Jenkins

Install the Allure Jenkins plugin, and configure it to read from the correct directory:

Jenkins will then offer a link to the results from the build status page:

Command-line

Install the Allure command-line tool, and process the results directory:

1

$ allure generate [allure_output_dir] && allure report open

This will generate a report (by default in ./allure-report), and open it in your browser:
