Test on Internal Networks

BrowserStack enables you to run your C# automated tests on your internal development environments, on localhost, and from behind a corporate firewall. This feature is called “Local Testing.”

Local Testing establishes a secure connection between your machine and the BrowserStack cloud. Once you set up Local Testing, all URLs work out of the box, including HTTPS URLs and those behind a proxy or firewall.

In this section, you’ll learn:

Prerequisites

If you have already run your first test, you can skip the prerequisites.

Run your first Local test

Configure your C# tests for Local Testing using the following steps:

  1. Clone the sample csharp-selenium-browserstack repository using the following command:
     git clone https://github.com/browserstack/csharp-selenium-browserstack.git
    
  2. Open the csharp-selenium-browserstack.csproj file and verify the BrowserStackLocal and Selenium NuGet packages are added to it:
       <ItemGroup>
         <PackageReference Include="Selenium.WebDriver" Version="3.141.0" />
         <PackageReference Include="BrowserStackLocal" Version="2.0.0" />
       </ItemGroup>
    
  3. Set your BrowserStack credentials in the csharp-selenium-browserstack/LocalTest.cs file as follows:
     // set your Username and Access Key in the capabilities
     capability.AddAdditionalCapability("browserstack.user", "YOUR_USERNAME");
     capability.AddAdditionalCapability("browserstack.key", "YOUR_ACCESS_KEY");
    
  4. Verify that the browserstack.local capability is set to true in the csharp-selenium-browserstack/LocalTest.cs file:
     capability.AddAdditionalCapability("browserstack.local", "true");
    
  5. Run the C# test in your IDE. You can also run the test by using the Run functionality of Visual Studio.
  6. View the test result on your Automate Dashboard.
Protip: Check out our capability builder and select from a range of custom capabilities that BrowserStack supports.

Understand your Local test script

When you run the C# test script, the LocalTest.cs file is executed. When the test is triggered, it:

  • Starts Local Testing connection
  • Opens http://bs-local.com:45691/check
  • Checks whether the web page contains the Up and running text
  • Marks the test as passed or failed based on the availability of the text
  • Stops the Local Testing connection.
