NUnit-Console Command Line Options

The console interface has a few additional options compared to the forms interface. The command line must always specify one or more file names. The console interface always creates an XML representation of the test results. This file by default is called TestResult.xml and is placed in the working directory.

Note: By default the nunit-console program is not added to your path. You must do this manually if this is the desired behavior.

Note: Under the Windows operating system, options may be prefixed by either a forward slash or a hyphen. Under Linux, a hyphen must be used. Options that take values may use an equal sign, a colon or a space to separate the option from its value.

Specifying an Assembly

The console program must always have an assembly or project specified. To run the tests contained in the nunit.tests.dll use the following command:
        nunit-console nunit.tests.dll

To run the tests in nunit.tests.dll through the Visual Studio project, use:

        nunit-console nunit.tests.csproj

To run the same tests through an NUnit test project you have defined, use:

        nunit-console nunit.tests.nunit

Specifying an Assembly and a Fixture

When specifying a fixture, you must give the full name of the test fixture along with the containing assembly. For example, to run the NUnit.Tests.AssertionTests in the nunit.tests.dll assembly use the following command:

        nunit-console /fixture:NUnit.Tests.AssertionTests nunit.tests.dll

The name specified after the /fixture option may be that of a TestFixture class, a legacy suite (using the Suite property ) or a namespace. If a namespace is given, then all fixtures under that namespace are run. This option may be used with Visual Studio or NUnit projects as well.

Specifying the Version of the CLR

Most applications are written to run under a specific version of the CLR. A few are designed to operate correctly under multiple versions. In either case, it is important to be able to specify the CLR version to be used for testing.

When only one version of the CLR is used, the config files for nunit-gui and nunit-console may be set up to specify that version. As a more convenient alternative when switching CLRs, you may use the provided clr.bat command to specify the version under which NUnit should run.

For example, to run the tests in nunit.tests.dll under the RTM version of the .Net 2.0 framework, use:

       clr net-2.0 nunit-console nunit.tests.dll

The clr.bat file is located in the NUnit bin directory. You may put this on your path, or copy it to a convenient location. Enter clr /? for a list of options.

Note: If you use a <startup> section in the config file, it takes precedence over this option.

Note: This command is specific to the Microsoft .Net framework. The Mono framework provides other means to specify the version to be used when running a command.

Specifying Test Categories to Include or Exclude

NUnit provides CategoryAttribute for use in marking tests as belonging to one or more categories. Categories may be included or excluded in a test run using the /include and /exclude options. The following command runs only the tests in the BaseLine category:

        nunit-console myassembly.dll /include:BaseLine

The following command runs all tests except those in the Database category:

        nunit-console myassembly.dll /exclude:Database

Multiple categories may be specified on either option, by using commas to separate them.

Note: Beginning with NUnit 2.4, the /include and /exclude options may be combined on the command line. When both are used, all tests with the included categories are run except for those with the excluded categories.

For a clear understanding of how category selection works, review the documentation for both the Category Attribute and the Explicit Attribute.

Redirecting Output

The output that is normally shown on the console may be redirected to a file. This includes output created by the test program as well as what NUnit itself creates. The following command redirects standard output to the TestResult.txt file:

        nunit-console nunit.tests.dll /out:TestResult.txt

The following command redirects standard error output to the StdErr.txt file.

        nunit-console nunit.tests.dll /err:StdErr.txt

Labeling Test Output

The output from each test normally follows right after that of the preceding test. You may use the /labels option to cause an identifying label to be displayed at the start of each test case.

Specifying the XML file name

As stated above, the console program always creates an XML representation of the test results. To change the name of the output file to "console-test.xml" use the following command line option:

        nunit-console /xml:console-test.xml nunit.tests.dll

Specifying the Transform file

The console interface uses XSLT to transform the test results from the XML file to what is printed to the screen when the program executes. The console interface has a default transformation that is part of the executable. To specify your own transformation named "myTransform.xslt" use the following command line option:

        nunit-console /transform:myTransform.xslt nunit.tests.dll

Note: For additional information see the XML schema for the test results. This file is in the same directory as the executable and is called Results.xsd. The default transform Summary.xslt is located in the core source directory.

Specifying which Configuration to run

When running tests from a Visual Studio or NUnit project, the first configuration found will be loaded by default. Usually this is Debug. The configuration loaded may be controlled by using the /config switch. The following will load and run tests for the Release configuration of nunit.tests.dll.

        nunit-console nunit.tests.csproj /config:Release

Note: This option has no effect when loading an assembly directly.

Specifying Multiple Assemblies

You may run tests from multiple assemblies in one run using the console interface even if you have not defined an NUnit test project file. The following command would run a suite of tests contained in assembly1.dll, assembly2.dll and assembly3.dll.

        nunit-console assembly1.dll assembly2.dll assembly3.dll

Notes: You may specify multiple assemblies, but not multiple NUnit or Visual Studio projects on the command line. Further, you may not specify an NUnit or Visual Studio project together with a list of assemblies.

Beginning with NUnit 2.4, the console loads multiple assemblies specified in this way into separate AppDomains by default. You may provide a separate config file for each assembly. You may override the default by use of the /domain option.

Beginning with NUnit 2.4, the /fixture option, when used with multiple assemblies, will run tests matching the fixture name in all the assemblies. In earlier versions, only the first test found was executed.

Controlling the Use of AppDomains

The /domain option controls of the creation of AppDomains for running tests. The following values are recognized:

No domain is created - the tests are run in the primary domain. This normally requires copying the NUnit assemblies into the same directory as your tests.
A test domain is created - this is how NUnit worked prior to version 2.4
A separate test domain is created for each assembly

The default is to use multiple domains if multiple assemblies are listed on the command line. Otherwise a single domain is used.

Other Options

The /noshadow option disables shadow copying of the assembly in order to provide improved performance.

The /nothread option suppresses use of a separate thread for running the tests and uses the main thread instead.

The /wait option causes the program to wait for user input before exiting. This is useful when running nunit-console from a shortcut.

The /xmlconsole option displays raw XML output on the console rather than transforming it. This is useful when debugging problems with the XML format.

The /nologo option disables display of the copyright information at the start of the program.

The /help or /? option displays a brief help message
