mocha-plugin-highland
A mocha plugin to enable Highland stream (using highland) support.
Installation
npm install --save-dev mocha-plugin-highland
- just add
-r mocha-plugin-highland
in your mocha command line npm script inpackage.json
{
"scripts" : {
"test": "node node_modules/mocha/bin/_mocha -r mocha-plugin-highland",
"coverage": "node node_modules/istanbul/lib/cli.js cover node_modules/mocha/bin/_mocha -- -r mocha-plugin-highland"
}
}
Example Usage
require('should');
var fs = require('fs');
var _ = require('highland');
var readFile = _.wrapCallback(fs.readFile);
describe('sometest', function () {
it('should read file and output a collection of names', () =>
readFile('myfile.txt')
.map(toUpperCase)
.map(function (x) {
return {name: x};
})
.collect()
.tap(arr => {
arr.should.containDeep([
{ name: 'Joe' },
{ name: 'Emma' },
{ name: 'Harry' },
{ name: 'Rachel' }
]);
})
);
it('does not change classical usage', function (done) {
setTimeout(done, 2000);
console.log('All good');
});
});
How It Works
The module monkey patches the Runnable.prototype.run
method of mocha
to enable the usage of Highland streams. In contrast to other npm packages, this is a plugin and extends mocha
at runtime - allowing you to use any compatible mocha version.
