withFixtures

A test helper to make sure fixtures are torn down and error messages are retained

Summary

function withFixtures([Fixture, Fixture, ...], Fn -> Promise<Any>) -> Promise<Any>

Example

const withFixtures = require('with-fixtures');

withFixtures([
  fixture1,
  fixture2
], () => {
  // Do test here and return a promise
}).then(() => console.log("Test passed"), err => cosole.warn("test failed"));

Notes

A Fixture is an object with a done() method. Any errors thrown while tearing down the fixture in the done method will be captured, and the first will be reported as a rejection of the promise chain, if the test itself did not reject.

All of the fixtures will have their done() method called.

For compatibility with sinon, if there is no done() method on a fixture but there is a restore() method, that will be called instead.

The promise will resolve to one of the following:

1. The rejection of the lifted function, if it exists
2. The first rejection while tearing down a fixture, if any
3. The value returned by the lifted function.
