Selenium with Rails -- The Working Case

Introduction

Just want to share my current working case, put all previous parts together, and more.

Online Demo

As you can see no diff image at second time since skipRealDiff is 'true'.

Pre-Request

Create Parameterized Test Service with Jenkins

Visual Testing with Selenium in Rails

Manage Image Files from Selenium Visual Testing

Steps to Apply This Project

1. Clone the WorkinCase/SeleniumTest

then you should be able to run

# run all test cases
rake test:fileset

or

# run all cases that quoted by single quote and separated by comma
cases="['simple_test']" rake test:fileset

in terminal

2. Create Jenkins Job with the content of Jenkins Job Settings at

README.rdoc


basically two parts, parameters and shell, then you can run it with Jenkins as the demo video shown above.

3. Regarding the Rails Web App, run it as your current user if you always run test cases from termnal, or run it by Jenkins as described in Manage Image Files from Selenium Visual Testing
if you usually run test cases with Jenkins

Modify test_helper.rb#L234 and Line 248 to your rails app url to change the url of output message


Different in Details

Add one more page '/vt/cases' to list all integration test cases (see routes.rb#L2 )

The working case postpone image processing by overriding MiniTest::CompositeReporter (see test_helper.rb#L200 ) so no need to read/write file.

Still override Rake::Task to rescue from rake aborted (see test.rake#L4 )
so Jenkins job will not be interrupted (since some operation needed after task finished)

Take care of Errors / Exceptions and Image diff to report summary of failed cases, see test_helper.rb
Line 35, 41, 240 ~ 256 and the if - fi block of Jenkins shell script

Take care of permission, see visual_testing_controller.rb#L66 , test_helper.rb#L259 and chmod command of Jenkins shell script
