Dockerfile for Nightwatch test execution
Based on caltha/protractor, this image contains a fully configured environment for running Nightwatch tests under the Chromium browser.
Installed software
- Xvfb The headless X server, for running browsers inside Docker
- node.js The runtime platform for running JavaScript on the server side, including Nightwatch tests
- npm Node.js package manager used to install Nightwatch and any specific node.js modules the tests may need
- Selenium webdriver Browser instrumentation agent used by Nightwatch to execute the tests
- OpenJDK 8 JRE Needed by Selenium
- Chromium The OSS core part of Google Chrome browser
- Nightwatch An end-to-end test framework for web applications
- Supervisor Process controll system used to manage Xvfb and Selenium background processes needed by Nightwatch
Running
In order to run tests from a CI system, execute the following:
docker build -t docker-nightwatch .
docker run --rm -v <test project location>:/project <docker id>
The container will terminate automatically after the tests are completed.
Your nightwatch.json must specify the no-sandbox option for Chrome to cleanly run inside Docker :
exports.config = {
// ...
"test_settings": {
// ...
"desiredCapabilities": {
"browserName": "chrome",
"marionette": true,
"chromeOptions": {
"args": [
"no-sandbox"
]
}
}
// ...
}
// ...
};
