Luckily, we can share the good vibes on social media. Often working on the other side of the world from each other. Much of this was a collaborative effort of developers contributing to the open source test frameworks NUnit, xUnit, and MSTest. The intent is to make that the default from 15.5 Preview 4.
This is presently shipped behind a feature flag. Test Discoveryīefore = VS 15.2 After = VS 15.5 Preview 2 + NUnit Adapter v3.9.0, published on + xUnit v2.3.1 published on Test Discovery performance improvements include the gains due to the new Source Information Provider implementation. You can find the links to the solutions in the table. These were timed using benchmark solutions of 10,000 tests. In the table below, you can see the before and after times of the most popular test frameworks and the percentage improvement per test runner. NUnit has also markedly improved performance. xUnit 2.3.0 has gone RTM bringing great performance improvements. MSTest v2 has experienced great adoption reaching 1.8 million downloads before even becoming the default option in MSTest projects. In Visual Studio 2017, unit test projects reference the MSTest Version 2 test framework by default. Test Platform and Test Adapter ImprovementsĮach of the top testing frameworks have made great accomplishments that make the whole experience better. The performance improvements are thanks to work in a few different areas, namely, Test Platform and Test Adapter improvements and a new feature called Real Time Test Discovery. These improvements are best shown in a side-by-side comparison of Visual Studio 2017 15.4 and Visual Studio 2017 15.5 Preview 2 with the Real Time Test Discovery feature flag turned on. NET and C++, but all had a common goal: make testing with our developer tools a great experience.NET Side-by-side Performance Comparison These efforts involved frameworks and tooling for both. There have been several significant improvements to the test experience that range across Visual Studio and Visual Studio Team Services.
