@lambdatesting is fantastic. Cross browser and device testingtesting frustration is minimized. You can’t get rid of clients that need ie11 nor can you own every device but lambda test bridge that gap.

Frequently Asked Questions

What is difference between MSTest and Selenium?
Selenium is a free and open-source framework for testing websites and webapps. It is used primarily for end-to-end automation of browser based web testing. It supports testing on all browsers, all operating systems and support all programming languages including C#. MSTest on the other hand, is a complete test automation framework that can used for unit tests, end-to-end tests, integration tests and basically complete test suites. It uses selenium webdriver in the backend and therefore in most practical use cases developers and testers use both frameworks together.
What are the benefits of MSTest for automation?
MSTest brings best of both worlds, cross browser versatility of Selenium, as well as added advanced capabilities of a full framework like reporting, running tests in parallel, annotations and much more. It makes the life of a tester easier.
Can MSTest be used to run parallel tests?
MSTest comes with out-of-the-box capabilities for running tests in parallel. With MSTest, you can use the same test case to run parallelly across more than one browser at a time.
How can I automate with MSTest using LambdaTest?
The LambdaTest Selenium Automation Grid allows you to run end-to-end MSTest automation tests on a secure, robust, and scalable Selenium infrastructure. With LambdaTest you can run your tests at scale across 3000+ different environments in parallel, resulting in higher test coverage and much shorter build times. Refer to our MSTest documentation.
