Unit-testing for those hard to reach places.
Uses Electron to provide a Mocha unit-testing environment which can be run headlessly or to debugged with DevTools. This was largely inspired by the electron-mocha and mocha-electron projects but didn't quite have the debugging features needed to develop tests.
Install globally:
npm install -g floss electronInstall locally within a project:
npm install floss electron --save-devOpen tests in an Electron window where test can can be debugged with debugger and dev tools.
await floss({
path: 'test/*.js',
debug: true
});The reporter and reporterOptions are pass-through options for Mocha to specify a different reporter when running Floss in non-debug mode.
await floss({
path: 'test/*.js',
reporter: 'xunit',
reporterOptions: {
filename: 'report.xml'
}
});Additional properties can be passed to the test code by adding more values to the run options.
await floss({
path: 'test/*.js',
customUrl: 'http://localhost:8080' // <- custom
});The test code and use the global options property to have access to the run options.
console.log(options.customUrl); // logs: http://localhost:8080Commandline arguments can be passed to Electron directly by using args. In the example below, you may wan to disable Electron's user-gesture policy if you are testing HTML video or audio playback.
await floss({
path: 'test/index.js',
args: ['--autoplay-policy=no-user-gesture-required']
});- --path or -p (String) Path to the file to test
- --debug or -d (Boolean) Enable to run in headful mode, default
false. - --quiet or -q (Boolean) Prevent console[log/info/error/warn/dir] messages from appearing in
stdout. - --electron or -e (String) Path to the electron to use.
- --reporter or -R (String) Mocha reporter type, default
spec. - --reporterOptions or -O (String) Mocha reporter options.
- --require or -r (String) Module to require (e.g.,
ts-node/register). - -- [args] Additional arguments can be passed to Electron after
--
Command Line usage when installed globally:
floss --path "test/*.js"Or installed locally:
node node_modules/.bin/floss --path "test/*.js"Alernatively, within the package.json's' scripts:
{
"scripts": {
"test": "floss --path \"test/*.js\""
}
}Open tests in an Electron window where test can can be debugged with debugger and dev tools.
floss --path "test/*.js" --debugSupport can easily be added for writing tests in TypeScript using ts-node.
floss --path "test/*.ts" --require ts-node/registerFloss supports nyc. To use it, just use floss as you would mocha:
nyc floss --path "test/*.js"Can use the same reporter options as the API mentioned above. The reporterOptions are expressed as a querystring, for instance varname=foo&another=bar.
floss --path "test/*.js" \
--reporter=xunit \
--reporterOptions output=report.xmlSupports passing additional arguments to Electron after --.
floss --path "test/*.js" -- --autoplay-policy=no-user-gesture-requiredSome application may require a specific version of Electron. Floss uses Electron 10.0.0+, but you can specific the path to your own version. The custom version can be used either through the commandline argument --electron, by setting the Node environmental variable ELECTRON_PATH or by setting the run option electron.
floss --path "test/.js" \
