Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Screenshot Reporter for Protractor

NPM version

Use the screenshot reporter to capture screenshots from your Selenium nodes after each executed Protractor test case.

Use meta data stored as JSON along with the screenshots to create extensive and human readable test reports.

Usage

The jasmine-screenshot-reporter is available via npm:

$ npm install jasmine-screenshot-reporter --save-dev

In your Protractor configuration file, register jasmine-screenshot-reporter in Jasmine:

var ScreenShotReporter = require('jasmine-screenshot-reporter');

exports.config = {
   // your config here ...

   onPrepare: function() {
      // Add a screenshot reporter and store screenshots to `/tmp/screnshots`:
      jasmine.getEnv().addReporter(new ScreenShotReporter({
         baseDirectory: '/tmp/screenshots'
      }));
   }
}

Configuration

Base Directory (mandatory)

You have to pass a directory path as parameter when creating a new instance of the screenshot reporter:

var reporter = new ScreenShotReporter({
   baseDirectory: '/tmp/screenshots'
});

If the given directory does not exists, it is created automatically as soon as a screenshot needs to be stored.

Path Builder (optional)

The function passed as second argument to the constructor is used to build up paths for screenshot files:

var path = require('path');

new ScreenShotReporter({
   baseDirectory: '/tmp/screenshots'
   , pathBuilder: function pathBuilder(spec, descriptions, results, capabilities) {
      // Return '<browser>/<specname>' as path for screenshots:
      // Example: 'firefox/list-should work'.
      return path.join(capabilities.caps_.browser, descriptions.join('-'));
   }
});

If you omit the path builder, a GUID is used by default instead.

Meta Data Builder (optional)

You can modify the contents of the JSON meta data file by passing a function metaDataBuilder function as third constructor parameter:

new ScreenShotReporter({
   baseDirectory: '/tmp/screenshots'
   , metaDataBuilder: function metaDataBuilder(spec, descriptions, results, capabilities) {
      // Return the description of the spec and if it has passed or not:
      return {
         description: descriptions.join(' ')
         , passed: results.passed()
      };
   }
});

If you omit the meta data builder, the default implementation is used (see https://github.com/swissmanu/protractor-screenshot-reporter/blob/master/index.js#L42).

Screenshots for skipped test cases (optional)

Since version 0.0.3, you can define if you want capture screenshots from skipped test cases using the takeScreenShotsForSkippedSpecs option:

new ScreenShotReporter({
   baseDirectory: '/tmp/screenshots'
   , takeScreenShotsForSkippedSpecs: true
});

Default is false.

Screenshots only for failed test cases (optional)

Also you can define if you want capture screenshots only from failed test cases using the takeScreenShotsOnlyForFailedSpecs: option:

new ScreenShotReporter({
   baseDirectory: '/tmp/screenshots'
   , takeScreenShotsOnlyForFailedSpecs: true
});

Default is false.

Postprocess Meta Data

A screenshot is saved as PNG image. Along with it, a JSON file with a matching filename is created.

By default, the JSON file contains the test outcome and further information about the Selenium machine which executed the test case:

{
   "description":"index.html header should fail",
   "passed":false,
   "os":"LINUX",
   "browser":{
      "name":"firefox",
      "version":"26.0"
   },
   "screenshot":"004200db-0032-005a-00f3-0072008c001c.png",
   "message":"TypeError: Cannot read property 'be' of undefined",
   "trace":"TypeError: Cannot read property 'be' of undefined\n    at null.<anonymous> etc."
}

By parsing these JSON files in a preprocessing step, you can generate a human readable test report.

Postprocessing is not a functionality of protractor-screenshot-reporter. Use Grunt or similar tools to integrate it into your test process.
