Advanced tools
Easy Sauce is a Node.js library that makes it easy to run JavaScript unit tests on the Sauce Labs cloud.
For a detailed explanation of how automated, cross-browser JavaScript unit testing works, and the motivation behind Easy Sauce, see the article Learning How to Set Up Automated, Cross-browser JavaScript Unit Testing.
Easy Sauce can be installed from npm by running the following command:
npm install easy-sauce
Note: running easy-sauce
requires at least Node.js version 6 (due to its use of es2015 code).
Easy Sauce comes with a command line interface (CLI) as well as a programatic API for use within Node.js.
The easy-sauce
command can be used as follows:
Usage: easy-sauce [options]
The easy-sauce command can by run by invoking the easy-sauce binary and passing
it a list of optional configuration options. The configuration options specified
will be merged with the the base configuration options set in either the
package.json file of the current working directory (under the "easySauce" key),
or, if the -c or --config option is specified, the JSON file at that location.
Options:
-c, --config A JSON config file to use instead of package.json.
-u, --username Your Sauce Labs username.
This defaults to the SAUCE_USERNAME environment variable.
-k, --key Your Sauce Labs access key.
This defaults to the SAUCE_ACCESS_KEY environment variable.
-P, --platforms An array of platform/browser/version capabilities.
This should be a JSON array of arrays, e.g.: '[["Windows
10", "chrome", "latest"], ["OS X 10.11", "safari", "9"]]'.
See https://goo.gl/tPnZDO for details.
-t, --test-path The URL path to the file that loads the tests.
Defaults to "/test/"
-p, --port The port to run the local server on.
Defaults to "8080"
-b, --build The build number to pass to Sauce Labs.
Defaults to the current time: $(date +%s)
-n, --name The name of the build to pass to Sauce Labs.
Defaults to "JS Unit Tests".
-f, --framework The test framework you're using. This can be "mocha",
"jasmine", "qunit", "YUI Test", or "custom".
Defaults to "mocha".
See https://goo.gl/5KfjDS for details.
-s, --service Service used to create the tunnel to localhost.
This can be "localtunnel", "ngrok", or "sauce-connect".
Defaults to "localtunnel".
See package details here:
https://www.npmjs.com/package/localtunnel
https://www.npmjs.com/package/ngrok
https://www.npmjs.com/package/sauce-connect-launcher
--service-options JSON configuration options to be passed to the tunnel
service. This is useful if you have a paid ngrok account
or need to specify additional sauce-connect options.
Example:
-s='sauce-connect' --service-options='{"verbose":true}'
-h, --help Displays this help message.
-V, --version Display the easy-sauce version number.
While all easy-sauce
options can be specified on the command line, it's usually easiest to declare the configuration options in an external JSON file that you reference via the -c
or --config
option.
easy-sauce -c path/to/config.json
If you're testing an npm package, you can skip the external configuration file and specify your configuration options directly in package.json
file under the "easySauce"
key:
{
"name": "my-package",
"version": "1.0.0",
"scripts": {
"test": "easy-sauce"
},
// ...
"easySauce": {
"port": "8080",
"testPath": "/test/runner.html",
"platforms": [
[
"Windows 10",
"chrome",
"latest"
],
[
"Linux",
"firefox",
"latest"
],
[
"OS X 10.11",
"safari",
"9"
]
],
"service": "sauce-connect",
"serviceOptions": {
"verbose": true
}
}
}
In the above example, the "tests"
command is also set to easy-sauce
, so now you can run your tests via npm:
npm test
This setup makes it very easy to integrate with services like Travis CI that use a lot of npm conventions as their default.
While it's possible to specify your Sauce Labs username and access key in your configuration file or package.json
, if you want to keep them secret you can assign them to the SAUCE_USERNAME
and SAUCE_ACCESS_KEY
environment variables, and the easy-sauce
CLI will automatically use those values.
To use Easy Sauce in Node.js, you can require('easy-sauce')
, which gives you a function that you invoke with a configuration options object corresponding to the CLI options listed above
The function returns an EventEmitter instance, which emits the following events that you can listen to and determine the progress of the tests.
Name | Arguments | Description |
---|---|---|
message | message (string) The message text. | Emitted when an event has occurred that may be useful for the user to know (e.g. the public URL of the tests after an ngrok tunnel has been created). |
update | job (Object) The updated JSON job data from Sauce Labs. | Emitted when the status of a job has changed. |
done |
passed (boolean) True if all tests passed.jobs (Object) The final JSON jobs data from Sauce Labs.
| Emitted when all test jobs have finished running. |
error | err (Error) The error object thrown.
| Emitted if an error occured while running the tests. |
Example Node.js usage:
const easySauce = require('easy-sauce');
easySauce({
username: process.env.SAUCE_USERNAME,
key: process.env.SAUCE_ACCESS_KEY,
platforms: [
[
'Windows 10',
'chrome',
'latest'
],
[
'Linux',
'firefox',
'latest'
],
[
'OS X 10.11',
'safari',
'9'
]
]
})
.on('message', function(message) {
// A message has been emitted, inform the user.
console.log(message);
})
.on('update', function(job) {
// A job's status has been updated
console.log(job.status);
})
.on('done', function(passed, jobs) {
// All tests have completed!
if (passed) {
console.log('All tests passed!');
}
else {
console.log('Oops, there were failures:\n' + jobs);
}
})
.on('error', function(err) {
// An error occurred at some point running the tests.
console.error(err.message);
});
If you'd like to contribute to the Easy Sauce library, make sure your changes pass the existing test suite. If your changes significantly alter the functionality of the library, make sure to update the tests in the /test
directory.
You can run the tests with the following command:
npm test
