Cordova Paramedic (Test Automation)

Android Testsuite iOS Testsuite Chrome Testsuite

Paramedic • noun provides advanced levels of care at the point of illness or injury, including out of hospital treatment, and diagnostic services

cordova-paramedic is a tool to automate execution of Cordova plugins tests (via cordova-plugin-test-framework).

You can use Paramedic to build and run a Cordova app with plugin tests, run these tests on local and remote emulators on Sauce Labs, and report the results. It can be used on a local or Continuous Integration environment.

Cordova Paramedic is currently used to automatically run all plugin tests on CI.

(See this workshop instructions for some additional explanation.)

Supported Cordova Platforms

What does it do?

A full Paramedic run will:

  1. <details> <summary>Create and prepare the app</summary>
    1. Create a temporary Cordova project with cordova create
    2. Install various plugins with cordova plugin add %local_path% (e.g. cordova plugin add ../cordova-plugin-inappbrowser):
      • the plugin to be tested (e.g. ../cordova-plugin-inappbrowser)
      • the tests of this plugin (e.g. ../cordova-plugin-inappbrowser/tests)
      • cordova-plugin-test-framework (from npm)
      • local paramedic-plugin
    3. Update the app start page to the test page at cdvtests/index.html (provided by cordova-plugin-test-framework and the plugin tests)
    4. Add the platform to be tested with cordova platform add ...
    5. Confirm the requirements for that platform are met with cordova requirements ...
    6. Start a local socket server for communication between the app running on a device/emulator and paramedic
    7. Make the server address known to the app
    </details>

  2. Run the tests <!-- 2-99 -->

Configuration file

Configuration file is used when no parameters are passed to cordova-paramedic call or explicitly specified via --config parameter:

cordova-paramedic           <- paramedic will attempt to find .paramedic.config.js in working directory
cordova-paramedic --config ./sample-config/.paramedic.config.js

Example configuration file is showed below.

module.exports = {
    // "externalServerUrl": "http://10.0.8.254",
    "useTunnel": true,
    "plugins": [
        "https://github.com/apache/cordova-plugin-inappbrowser"
    ],
    "platform": "windows",
    "action": "run",
    "args": "--archs=x64 -- --appx=uap"
}

More configuration file examples could be found in sample-config folder.

API Interface

You can also use cordova-paramedic as a module directly:

var paramedic = require('cordova-paramedic');
paramedic.run(config);

Quirks

Windows

For Paramedic to work correctly for Windows apps you'll need to allow the loopback for "HelloCordova" app using Windows Loopback Exemption Manager (download).
