The Visual Studio Test Platform is an open and extensible test platform that runs tests, collects diagnostics data, and reports results. The Test Platform supports running tests written in various test frameworks, and using a pluggable adapter model. Based on user-choice, the desired test framework and its corresponding adapter can be acquired as a vsix or as NuGet package as the case may be. Adapters can be written in terms of a public API exposed by the Test Platform.

The Test Platform currently ships as part Visual Studio 2019, and in the .NET Core Tools Preview 3.

IMPORTANT: We only accept PRs for which exists a previously discussed and approved issue.

There are many ways to contribute to VSTest

• Submit issues and help verify fixes as they are checked in.
• Review the open PRs.
• Contribute features and fixes.
• Contribute to the documentation.

NOTE: When adding a new public API, always add it directly to the PublicAPI.Shipped.txt file. This helps us ensure we are always considering potential breaking changes (even between successive commits of un-released version) and avoids the burden of the unshipped to shipped commit.
