protractor-fail-fast

protractor-fail-fast

Allow Protractor tests to "fail-fast", exiting on the first failure instead of running all tests no matter what. This can save a great deal of time as Protractor tests are typically slow and expensive.

This Protractor plugin is essentially a wrapper around jasmine-fail-fast, solving the problem of halting multiple Protractor instances once one of them has failed. Otherwise, a multi-capability Protractor test will take as long as the longest running test instance, potentially as long as if jasmine-fail-fast wasn't applied at all.

Install

npm install protractor-fail-fast

Usage

In the Protractor conf:

var failFast = require('protractor-fail-fast');

exports.config = {
  plugins: [{
    package: 'protractor-fail-fast'
  }],

  onPrepare: function() {
    jasmine.getEnv().addReporter(failFast.init());
  },
  
  afterLaunch: function() {
    failFast.clean(); // Cleans up the "fail file" (see below)
  }  
}

Fail file

In order to facilitate communication between the test instances (and for the lack of a better known option), protractor-fail-fast writes to an empty file, .protractor-failed, whenever a test fails. The presence of this file triggers all other test instances to skip the rest of their tests.

The init and clean methods will remove this file, but it may still remain if, for example, the afterLaunch Protractor hook isn't executed due to an aborted test run. For that reason, it's recommended to add .protractor-failed to .gitignore.

Changelog

1.0.2

Fixes

• Add protractor as a < 2.2.0 peerDependency to indicate that 1.x isn't compatible with protractor 2.2.0 and above.
