CodeceptJS Nightmare Test Harness

The following repository provides a basic structure for testers to quickly spin up their own automation projects using CodeceptJS and Nightmare.

Setup Info

First, to install the necessary packages run npm install. This will install the following packages:

  • CodeceptJS
  • CodeceptJS-Nightmare
  • Nightmare
  • Nightmare-upload
  • Mochawesome

Tip: If you run into SyntaxError: Unexpected token ), you can follow the suggestions on this issue to clear things up.

This repo has already initialized a codeceptjs-nightmare project. However, if you want to initialize a new project, simply delete codecept.json, run codeceptjs init, and follow the prompts.

Additional Test Setup

CodeceptJS provides generators for different parts of your tests. We have already provided a few samples you can use as templates. To generate any new files, you can run the following:

  • Test Scenarios: codeceptjs gt
  • Page Objects: codeceptjs gpo
  • Page Fragments (modals or widgets, for example): codeceptjs go --type fragment
  • Step Objects: codeceptjs go --type step

Each generator will update the includes section of codecept.json.

Running Tests

Once everything is installed, you can simply execute npm tests to run the existing test. The codecept.json file houses the configurations needed to run tests. Here is a portion of that file with notes on important features:

{
  "output": "./output", // screenshots for failures
  "helpers": {
    "Nightmare": {
      "url": "https://moduscreate.com/",
      "show": true, // tests run in a window
      "restart": false // uses a single browser instance
    }
  },
  "include": { // set up by codeceptjs generators
    "modusHomePage": "./pages/modusHomePage.js",
    "modusEmailModalFragment": "./fragments/modusEmailModal.js",
    "navigateHomePageStep": "./steps/navigateHomePageStep.js"
  }
}

Tags

CodeceptJS offers the ability to group scenarios using tags. This gives you greater flexibility in how you organize tests.

Scenario('Navigate to Home Page @home', () => {});

To run based on tags, execute codeceptjs run --grep @tagName. CodeceptJS also provides more advanced regex filtering.

  • --grep (?=.*@smoke2)(?=.*@smoke3) - run tests with @smoke2 and @smoke3 in name
  • --grep @smoke2|@smoke3 - run tests with @smoke2 or @smoke3 in name
  • --grep ((?=.*@smoke2)(?=.*@smoke3))|@smoke4 - run tests with (@smoke2 and @smoke3) or @smoke4 in name
  • --grep (?=.*@smoke2)^(?!.*@smoke3) - run tests with @smoke2 but without @smoke3 in name

Reporters

CodeceptJS offers a few different reporter options. This repo is set up with mochawesome, a tool for generating HTML reports.

Docker-Compose

This project comes with the ability to run tests in a Docker container via docker-compose. It uses the Docker image from the Codeception team, and provides all of the necessary dependencies to run tests.

Run docker-compose up -d codeceptjs then docker-compose run --rm codeceptjs.

You can’t perform that action at this time.
