Grunt task to run Cucumber.js. Outputs results in various HTML themes. Runs Cucumber.js in Parallel
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-cucumberjs --save-devNote:
- Install grunt-cucumberjs@1.0.2 for cucumber version < Cucumber@2
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-cucumberjs');
In your project's Gruntfile, add a section named cucumberjs to the data object passed into grunt.initConfig().
grunt.initConfig({
cucumberjs: {
options: {
format: 'html',
output: 'my_report.html',
theme: 'bootstrap'
},
my_features: ['features/feature1.feature', 'features/feature2.feature'],
other_features: {
options: {
output: 'other_report.html'
},
src: ['other_features/feature1.feature', 'other_features/feature2.feature']
}
}
});If all your feature files are located in the default location of features/ then just leave the feature configuation as an empty array. See following:
cucumberjs: {
options: {
format: 'html',
output: './public/report.html',
theme: 'foundation'
},
features : []
}
#runs all features specified in task
$ grunt cucumberjs
#you can override options via the cli
$ grunt cucumberjs --require=test/functional/step_definitions/ --features=features/myFeature.feature --format=prettyType: String
Default: ''

Use if step_definitions and hooks are NOT in default location of features/step_definitions
Type: String|Array
Default: ''
Passes the value as --tags parameter to cucumber. If an array, each item is passed as a separate --tags parameter.
We've seen issues in cucumberjs using the old style of negative tag expression such as '~@ignore'. Suggest that you use the expanded syntax 'not @ignore' instead.

Rerun the failed scenarios recorded in the @rerun.txt file.
To Re-run failed scenarios:
- Set the cucumber-js task format to
rerun:@rerun.txt
options: {
format: 'rerun:@rerun.txt',
.....
....
}
It will record all the failed scenarios to @rerun.txt.
Take a look at options.formats to generate html report
- Run failed scenarios by passing
--rerun=path/to/@rerun.txtgrunt option
N.B.: If @rerun.txt file does not exists or if file is empty, the grunt task will return success.
