Run Selenium tests in multiple browsers one after another from C# NUnit

Question

I\'m looking for the recommended/nicest way to make Selenium tests execute in several browsers one after another. The website I\'m testing isn\'t big, so I don\'t need a par

Answer 1

This is a recurring question and is solved a couple ways:

1. Factory method produces your ISelenium object - You have a helper class with a static getSelenium method. That method reads in some external config, which has a property that defines the browser you want as a string. In your getSelenium you then configure the browser accordingly. here's a handy post on using config files with NUnit http://blog.coryfoy.com/2005/08/nunit-app-config-files-its-all-about-the-nunit-file/

2. Others have success with injecting the browser via an IoC container. I really like this because TestNG works really well with Guice in Java land, but I'm not sure how easy it is to mix NUnit and Ninject, MEF, etc...

Answer 2

Ok, one solution is to have wrapper tests that set-up the ISelenium object with different browsers. Then they pass that object to all the other tests which use it instead of setting up a new one themselves like they did previously.

The disadvantage is, I end up with one big test for each browser. Not the best solution either. Still looking...

EDIT:

Spent some more time on this. The solution I came up with is to have a text file in the solution that specifies the browser to use for testing. NUnit picks up the setting when instantiating a Selenium object.

I'm using CruiseControl.NET to run automatic builds and tests. And instead of just running the test once, I configured it to run them twice. But before each test I run a command line command that changes the browser in the configuration text file.
