Karma-Chromium-Edge-Launcher

Launcher for Chromium Edge Canary, Dev, Beta and Stable channels for Windows OS, Mac OS and Linux OS

Available in NPM Registry

Installation

Install the package as dev-dependency

npm i -D @chiragrupani/karma-chromium-edge-launcher

Configuration

Update Karma.conf.js replace or append to array of browsers and add require plugin as below:

// karma.conf.js
module.exports = function (config) {
  config.set({
-     browsers: ['Chrome'],
+     browsers: ['Edge'],
    plugins: [
-      require('karma-chrome-launcher'),
+      require('@chiragrupani/karma-chromium-edge-launcher'),
    ],
  });
};

Following browser channels are supported, add corresponding string in browsers:

• "Edge"
• "EdgeDev"
• "EdgeBeta"
• "EdgeCanary"

If you want to launch browser in headless mode, below is correspondling list:

• "EdgeHeadless"
• "EdgeDevHeadless"
• "EdgeBetaHeadless"
• "EdgeCanaryHeadless"

If you want to explicity specify the path for browser installation, set environment variable from this list, corresponding to release channel:

EDGE_BIN, EDGE_BETA_BIN, EDGE_DEV_BIN, EDGE_CANARY_BIN

Example:

# Add at top of karma.conf.js
process.env.EDGE_DEV_BIN =
  "C:\\Program Files (x86)\\Microsoft\\Edge Dev\\Application\\msedge.exe";

That's all is required to use Karma with Chromium Edge browser.

The browser can also be specified with npm test commmand like below:

 "coverage": "ng t --no-watch --code-coverage --reporters=junit,coverage-istanbul --browsers=EdgeHeadless --progress=false"

Build from Source

In case if you want to build package from github source

# Clone/download the package

# Run in clonned directory to install dependencies
npm install

# Run in clonned directory
npm run package  # Generates package in tgz format

# Run in angular project
# Provide path to tgz file generated in earlier step
npm install -g <path/to/tgz>

The project is based on karma-chrome-launcher as most of flags/configs for Chromium Edge are similar to Chrome browser
