Can we do parallel execution in selenium?

Selenium parallel execution enables organizations to simultaneously run tests in parallel on different devices and browsers to significantly shrink testing times.

Can selenium be used with Visual Studio?

If you want to use selenium in Visual Studio 2019, you just need to download and install selenium NuGet packages. You can download them by right-clicking the project > Manage NuGet Packages… > Browse > select and install (note to choose the proper versions).

How does parallel execution work in selenium C #?

Parallel execution in Selenium is the starting point for speeding up the test execution, as tests can be run simultaneously against different ‘environments.’ SpecFlow, the .NET-based framework for BDD (Behavior Driven Development) and Acceptance-driven test development used by Selenium C# Automation testers also support parallel execution.

How to run parallel tests in Visual Studio?

So tests in the same test project will still run sequentially. Of course, with large test suites for several modules, proper structuring of code should almost automatically result in several projects. Another way to run in parallel is described here, in short: add the node to the node in your TestSettings.xml.

How does the parallel execution work in SpecFlow?

Here, each thread’s memory (e.g., static fields) is isolated, and each test execution thread is hosted in a separate AppDomain. The SpecFlow+ runner (or SpecRun) has to be used for executing SpecFlow tests in parallel, as the runner supports parallel test execution with AppDomain, SharedAppDomain, and Process Isolation.

Why is NUnit used for parallel test execution?

Parallel test execution using this approach helps in minimizing the initialization footprint, thereby lowering the memory requirements. The NUnit test runner lets you run SpecFlow tests in parallel without AppDomain isolation.
