Mocha Stress


Stress-test inconsistent parts of your Mocha test suite to identify and correct flaky tests.

Installation

mocha-stress requires node.js >= 4.

``sh


Install the package from npm

$ npm install --save-dev mocha-stress

Add this argument to your Mocha command-line arguments:

$ jq .scripts package.json
{
"test": "mocha -r mocha-stress"
}

Or to your ./test/mocha.opts file:

$ cat ./test/mocha.opts
--require mocha-stress
`

Usage

To run a specific spec a fixed number of iterations:

`js
it.stress(100, 'is failing sometimes for some reason??', function () {
expect(Math.random()).to.be.below(0.5)
})
`

It can also be used on an entire describe suite:

`js
describe.stress(100, 'inconsistent', function () {
// ..
})
`

This implies .only()`.
