Run your Coded UI tests against different browsers using the Selenium components

Run your coded ui tests against the different browsers using the

selenium components.

If we have a dedicated agent machines with browser to run the 

coded ui test with out modifying the code.

For this i am using the system variables. In each machine i will 

create a system variable name:browser and value is like "IE" 

or "Chrome" or "Firefox" ect 

Ex: Agent-1 should run with IE browser and Agent-2 should run

 with Chrome browser...

Download the Selenium components from below link

Right click on the downloaded zip files.

Select "properties".

Setting Environment Variables for Coded UI

Create environment variable on each agent machine and set its value

 as the desired browser name (IE8/IE9/Chrome/Firefox) against which

 you want to run your automated tests.

1.Go to “My Computer” Right click and select “Properties”

2.Click on “Advance System Settings”

3.Go to “Advance Tab” and the click on “Environment Variables” 

4.Under “system variables” section click on “New”

5.Give the “Variable Name” and “Variable Value”

6.Click on “ok” and again click on “ok” and again click on “ok”.

7.Create a Test Initialize method and read the value of the                               environment variable before test starts on each agent machine.

   This will return the name of the browser that needs to be used 

   for playing back automation.

String browser;

        [TestInitialize]

        public void Init()

        {

            browser                            = Environment.GetEnvironmentVariable("LaunchBrowser");

        }

8.Inside your test method, set “BrowserWindow.CurrentBrowser”

   value as “browser” which holds the browser name stored in 

   environment variable

Sample code…

[TestMethod]

public void CodedUITestMethod1()

{

    BrowserWindow.CurrentBrowser = browser;

    this.UIMap.RecordedMethod1();

    this.UIMap.AssertMethod1();

}

Depending on the value stored in the environment variable, Coded UI launches the browser and runs the test against launched browser.
