mocha-nightmare v0.1.2

mocha-nightmare

Caution

This is very early days concept :| You shouldn't expect too much out otf it. Created for a specific purpose which is far more important then the tool itself.

Motivation

Because javascript UI tests should be run in the browser :] This is a different idea of running UI tests: instead of using API that allows you to manipulate the browser like nightwatch, selenium or nightmare it lets you run your tests directly in the browser.

How it works

It's very simple :] mocha-nightmare does the following things:

• launches nightmare (headless or headfull)
• sets up mocha test environment
• opens tested webpage
• injects you js files to the tested webpage context
• runs tests
• returns test results in xunit XML format

Usage

You might want to install it globally

npm i mocha-nightmare -g

prepare json configuration file

{
  "testResources": [
    "<path_to_js_file_you_want_be_injected_to_the_browser>"
  ]
}

run tests

mocha-nightmare -u http://<tested_page_url> -r <json_configuration_file_path>

check output (example printout)

<testsuite name="Mocha Tests" tests="1" failures="0" errors="0" skipped="0" timestamp="Tue, 22 Nov 2016 13:14:01 GMT" time="0.035">
  <testcase classname="example test suite" name="example test" time="0"/>
</testsuite>
