Testing tools

Write high-quality code with comprehensive testing tools using the latest Visual Studio

IntelliTest

Dramatically reduce the effort to create and maintain unit tests for new or existing code. Generate interesting input-output values for your methods, and save them as a small test suite with high code coverage. Automatically evolve them as your code evolves.

Test Explorer

Code coverage analysis

Visualize and report on line level and block level code coverage for both managed and native applications.

Rich isolation framework that allows you to replace any .NET method with a delegate. The Fakes Framework in Visual Studio supports unit testing by providing isolation by way of detours and stubs.

Free, fully-featured IDE for students, open-source and individual developers.

Powerful developer tools, services, and subscription benefits for efficient small-team collaboration.

Advanced debugging, enterprise security, AI-assisted development—plus Azure Credits and Dev/Test pricing for the cloud.
