nxus-tester

A test management framework for Nxus applications. The tester module provides some helper functions for funtionally testing a Nxus app.

Installation

> npm install nxus-tester --save-dev

Configuration

You will want to use mocha as your test runner in your application project, here's a standard npm test script for your package.json

"test": "NODE_ENV=test mocha --recursive --compilers js:babel-register -R spec modules/test/*",

Usage

Test Server startup

Any test suites that want to make requests to a running instance of your application should use startTestServer:

describe("My App", function() {
    before(function() {
        this.timeout(4000) // Depending on your apps startup speed
        startTestServer()
    })
    ... // Your tests
})

This is safe to call in multiple suites, only one test server will be started. You may pass an object as an optional second argument to startTestServer for command ENV variables, such as DEBUG or overriding test database names.

Running tests

> npm test

Requests

Requests to the test server can be made using helper methods for the requests-with-promises library.

import {request, requestRaw, requestLogin} from 'nxus-tester'

request returns the body of a successful response

let body = await request.get('/') // or request({url: '/', ...})
res.statusCode.should.equal(200)

or errors with a non-2XX response

let body = await request.get('/notHere')
 .catch(request.errors.StatusCodeError, (err) => {...})

requestRaw returns the response object, if you want to check statusCode, headers, etc let res = await requestRaw.get({url: '/admin', followRedirect: false}) res.statusCode.should.equal(302) res.headers.location.should.contain('/login')

requestLogin`` creates a new cookie jar and logs in as the requested username/password and returns a request object to use likerequest`. let req = await requestLogin('user@dev', 'test') let body = await req.get({url: '/admin'})

Fixtures

You can define fixtures (json or csv files with data to load during test startup) manually in your application modules: app.get('tester').fixture('modelName', 'path/to/fixture.json')

Or by creating a top-level application fixtures directory with files named for the models they contain fixture data for.

Use models and nxus modules in tests

The test server is started in the same process as your tests, so you may use e.g. storage.getModel() in your before() and test methods to create test data and assert that requests modify data.
