Learn how to use MSTest framework to configure and run your C# automation testing scripts on the LambdaTest platform

• Pre-requisites
• Run Your First Test
• Parallel Testing With MSTest
• Local Testing With MSTest

Before you can start performing MSTest automation testing with Selenium, you would need to:

• Download and Install Selenium WebDriver from its official website.
• Make sure you have latest version of C#.
• .Net framework to deliver guidelines while developing a range of application using C#.
• Download Selenium WebDriver Language Binding for C# and extract them to appropriate folder.
• A .NET Core SDK of 3.0.0.

Step 1: Clone the LambdaTest’s MSTest-Selenium-Sample repository and navigate to the code directory as shown below:

git clone https://github.com/LambdaTest/MSTest-Selenium-Sample
cd MSTest-Selenium-Sample

Make sure you have your LambdaTest credentials with you to run test automation scripts with C# on LambdaTest Selenium Grid. You can get these credentials from the LambdaTest Automation Dashboard or by your LambdaTest Profile.

Step 2: Set LambdaTest Username and Access Key in environment variables.

For Linux/macOS:

export LT_USERNAME="YOUR_USERNAME" export LT_ACCESS_KEY="YOUR ACCESS KEY"

For Windows:

set LT_USERNAME="YOUR_USERNAME" set LT_ACCESS_KEY="YOUR ACCESS KEY"

Test Scenario: This MSTest Selenium script tests a sample to-do list app by marking couple items as done, adding a new item to the list and finally displaying the count of pending items as output.

Step 3: Check out the LocalMSTest.cs file for sample test case.

Step 4: In the test script, you need to update your test capabilities. In this code, we are passing browser, browser version, and operating system information, along with LambdaTest Selenium grid capabilities via capabilities object. The capabilities object in the above code are defined as:

DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.SetCapability(CapabilityType.BrowserName, "Chrome");
            capabilities.SetCapability(CapabilityType.Version, "96");
            capabilities.SetCapability(CapabilityType.Platform, "Windows 10");

Note: You can generate capabilities for your test requirements with the help of Desired Capabilitiy Generator.

Step 5: Build the solution by clicking in Build > Build Solution.

Step 6: As shown below click on Test Explorer on your MS Visual Studio:

Step 7: Click on Run from the Test Explorer to run the sample test as shown below:

Executing in Linux/macOS:

dotnet test MS-Test-Cross-Browser.csproj

Your results would be displayed on the test console and on the LambdaTest Automation Dashboard.

To run parallel tests, open Visual Studio and go to Test Explorer and then click on Run All tests to execute the tests. Your results would be displayed on the test console and on the LambdaTest Automation Dashboard.

You can test your locally hosted or privately hosted projects with LambdaTest Selenium grid using LambdaTest Tunnel. All you would have to do is set up an SSH tunnel using tunnel and pass toggle tunnel = True via desired capabilities. LambdaTest Tunnel establishes a secure SSH protocol based tunnel that allows you in testing your locally hosted or privately hosted pages, even before they are live.

Refer our LambdaTest Tunnel documentation for more information.

Here’s how you can establish LambdaTest Tunnel.

Download the binary file of:

• LambdaTest Tunnel for Windows
• LambdaTest Tunnel for macOS
• LambdaTest Tunnel for Linux

Open command prompt and navigate to the binary folder.

Run the following command:

LT --user {user’s login email} --key {user’s access key}

So if your user name is [email protected] and key is 123456, the command would be:

LT --user [email protected] --key 123456

Once you are able to connect LambdaTest Tunnel successfully, you would just have to pass on tunnel capabilities in the code shown below :

Tunnel Capability

DesiredCapabilities capabilities = new DesiredCapabilities();        
        capabilities.setCapability("tunnel", true);
