karma-cucumber-js-latest

In contrast to other adapters this one supports the latest version of Cucumber.js (6.0.5). The minimum supported Karma is 1.3.0. The minimum Supported Cucumber.js is 3.0.5. This adapter does not include Cucumber.js or Karma.js, because they are peer dependencies.

Getting Started

npm install cucumber --save-dev
npm install karma --save-dev
npm install karma-cucumber-js-latest --save-dev

Step Definitions

step definitions are written like this (no need to re-import cucumber methods, as shown in official documentation, as the karma adapter does this for your already):

Given(/^there is a test step$/, function () { });
When(/^it is executed$/, function () { });
When(/^step is pending$/, function (callback) { callback(null, 'pending'); });
Then(/^test succeeds$/, function () { });
Then(/^test fails$/, function (callback) { callback(new Error('Step failed')); });
