Run Tests in Parallel

Run multiple MBUnit tests in parallel on BrowserStack Automate

Note: Code samples in this guide can be found in the mbunit-browserstack sample repo on GitHub

On BrowserStack, you can run multiple MBUnit tests at the same time across various browser, device and OS combinations. This is “Parallel Testing”. Parallel Testing gives you the same benefits as running a multi-threaded application helps you reduce the run time of your test suite, resulting in faster build times and faster releases.

To run tests on multiple browsers in parallel with MBUnit on BrowserStack Automate, follow the below steps:

  1. Clone the mbunit-browserstack repo on GitHub(if not already done):

     git clone https://github.com/browserstack/mbunit-browserstack.git
    
  2. Open the solution MBUnit-BrowserStack.sln in Visual Studio.

  3. Setup your credentials and browser/devices where you want to run your test, in the App.config file within mbunit-browserstack/MBUnit-BrowserStack/ directory as shown below:

     <?xml version="1.0" encoding="utf-8" ?>
     <configuration>
       <configSections>
         <sectionGroup name="capabilities">
           <section name="parallel" type="System.Configuration.AppSettingsSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
         </sectionGroup>
    
         <sectionGroup name="environments">
           <section name="chrome" type="System.Configuration.AppSettingsSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
           <section name="firefox" type="System.Configuration.AppSettingsSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
           <section name="safari" type="System.Configuration.AppSettingsSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
           <section name="ie" type="System.Configuration.AppSettingsSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
         </sectionGroup>
       </configSections>
    
       <appSettings>
         <add key="user" value="YOUR_USERNAME" />
         <add key="key" value="YOUR_ACCESS_KEY" />
         <add key="server" value="hub-cloud.browserstack.com" />
       </appSettings>
    
       <capabilities>
         <parallel>
           <add key="browserstack.debug" value="true" />
         </parallel>
       </capabilities>
    
       <environments>
         <chrome>
           <add key="browser" value="chrome" />
         </chrome>
         <firefox>
           <add key="browser" value="firefox" />
         </firefox>
         <safari>
           <add key="browser" value="safari" />
         </safari>
         <ie>
           <add key="browser" value="ie" />
         </ie>
       </environments>
     </configuration>
    
  4. You can now run your tests in parallel on BrowserStack using the following steps:

    1. Build the solution in Visual Studio
    2. Run tests with fixture parallel from Test Explorer
  5. You can add other capabilities under the environments option as shown below:

    <environments>
       <chrome>
         <add key="browser" value="chrome" />
         <add key="browser_version" value="latest" />
         <add key="os" value="Windows" />
         <add key="os_version" value="10" />
       </chrome>
    </environments>
    
Protip: You can use our capability builder and select from a wide range of custom capabilities that BrowserStack supports.
