NUnit Support
There are multiple ways to run tests with NUnit to support TeamCity's test reporting ability:
for NAnt build: use standard
<nunit2>task in NAnt build (it is NUnit for NAnt build runner with TeamCity-capable task);for MSBuild build: use standard
<NUnit>task from the MSBuild Community tasks (it is NUnit for MSBuild with TeamCity-capable task);use TeamCity-provided TeamCity NUnit Test Launcher
use TeamCity addin for NUnit to turn on reporting on NUnit level without build procedure modifications;
for unsupported frameworks: manually report test results via Build Script Interaction with TeamCity.
For all supported NUnit versions TeamCity tracks the tests and reports all the information on-the-fly (both in the web UI and your IDE). In real-time mode TeamCity Tests Tab on every test run within a build: its status, name, package, duration, and statistics.
TeamCity informs user about tests failure immediately and provides details on occurred errors on the Overview tab of Build Results Home Page. For each failed or ignored test TeamCity web UI provides a direct link to open it in your IDE.
Besides, TeamCity relieves a headache of running your tests under x86 process on the x64 machine by introducing an explicit specification of the platform and run-time environment versions. You can define whether you use .NET 1.1 and MSIL, x64 or x86 platform to use for .NET 2.0 version in TeamCity NUnit Test Launcher, NUnit for NAnt Build Runner, NUnit for MSBuild, sln2003, sln2005, sln2008.
