3 years ago As mentioned in the other issue all Cucumber functions are globally available in the step files. So no need to import them as the plugin already does that when karma instantiates the cucumber plugin.
Can't seem to set a custom world for my tests - see error at bottom:
dev dependencies:
```js "devDependencies": { "chai": "4.2.0", "cucumber": "6.0.5", "karma": "4.4.1", "karma-chai": "0.1.0", "karma-chrome-launcher": "3.1.0", "karma-cucumber-js-latest": "1.0.5", "karma-mocha": "1.3.0", "mocha": "7.0.1", "puppeteer": "2.1.1" } ```
karma.conf.js:
```js process.env.CHROME_BIN = require('puppeteer').executablePath() module.exports = function(config) { config.set({ frameworks: ["mocha", "chai", "cucumber-js"], browsers: ["ChromeHeadless"], singleRun: true, files: [ "test/**/*.js", ... {pattern: "features/*.feature", included: false} ], plugins: [ "karma-mocha", "karma-chai", "karma-chrome-launcher", "karma-cucumber-js-latest" ] }) } ```
World.js:
```js const setWorldConstructor = Cucumber.setWorldConstructor class CustomWorld { constructor() { this.agents = new Map() this.results = new Map() } ... } setWorldConstructor(CustomWorld) ```
Error
