Our verdict

  • Highest scoreMSTest · 8.8/10
  • Free planonly NUnit

MSTest scores higher on our rubric for unit testing: 8.8 against 8.7 out of 10; our editors rank them #7 and #8.

MSTest is the better fit for .NET teams using Microsoft's test tooling. NUnit is the better fit for .NET teams needing parameterized, parallel tests.
