Compatibility

This section describes how to run tests created in older versions of NUnit using NUnit 2.2 and highlights the most significant changes made in the last two releases of NUnit.

Using NUnit 2.0 Tests with NUnit 2.2

There are two options for running NUnit 2.0 tests with NUnit 2.2. The first option is to upgrade the 2.0 tests and recompile the test assemblies using the new nunit.framework assembly.

The second option allows you to run NUnit 2.0 tests with NUnit 2.2 without changing the NUnit 2.0 tests. Create the appropriate binding redirect in the test runner configuration file (nunit-gui.exe.config or nunit-console.exe.config).

Upgrading from NUnit 1.x to 2.2

You cannot run NUnit 1.x tests using NUnit 2.2—the only option is to upgrade the Version 1.x tests. The following points outline the changes you must make to ...
