NUnit Launcher (nunit.jar)

The NUnit launcher allows interfacing with .NET tests (C#, J#, C++/CLI, Managed C++, VisualBasic.NET).
It has been tested with NUnit 2.5.2


Configuration

The nunit.xml file is just a template and must NOT be edited. It's used by the system to build dynamically the form that the user will be able to fill in from the GUI when creating a custom execution configuration.

Parameter Description
General > Test root path This must indicate where are located all the Squish tests. This is a root path. Each test in XStudio has a canonical path that will be appended to this path.
This path MUST not include an ending slash.

Default value is: C:/Program Files/NUnit 2.5.2/bin/net-2.0/tests
General > Assembly dll Default value is: nunit.util.tests.dll
NUnit > NET version Default value is: 2.0
NUnit > NUnit console path Default value is: C:/Program Files/NUnit 2.5.2


These values can be changed while creating the campaign session from XStudio.


Process

The tests are executed by the launcher using this syntax:

<nunitConsolePath>/bin/net-<netVersion>/nunit-console.exe /run:<testPath>.<testName> <testRootPath>/<assemblyName>

And this is executed from the working directory <testRootPath>

The test will be marked as passed or failed depending on the log file generated by NUnit. The text file is parsed by the launcher. The log and the execution trace of the command are also attached to the testcase execution in XStudio.

Tutorial: Creating and executing NUnit tests

In this tutorial, we will learn to run some NUnit tests. We will use NUnit 2.5.2 but this can be applied to any version of NUnit. As an example, we will execute three sample tests provided with NUnit 2.5.2: PathUtilTests, ProjectConfigTests and TestAgencyTests


Prerequisites

Install NUnit 2.5.2 in the folder C:\\Program Files\\NUnit 2.5.2


Create a dedicated category for NUnit tests and create three tests

  • create a category NUnit associated to the launcher nunit.jar
  • under this category, create (somewhere in the tree) the three tests with the names PathUtilTests, ProjectConfigTests and TestAgencyTests and a canonical path set to NUnit.Util.Tests.



Creating a test campaign

  • create a campaign including the tests PathUtilTests, ProjectConfigTests and TestAgencyTests.
  • create a campaign session with the default configuration settings.


Run a campaign session

Run the campaign session





Permissions

WARNING: if you're running your tests on Windows, it may be required to run the tests as administrator.
Having an account with Administrators permissions may even not be enough in some cases (especially if you're using Windows 10) and you may need to disable completely the UAC (User Access Control) on your computer.

To do so:
  • Press the Windows + R key combination
  • Type in regedit
  • Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
  • In the right-side pane, look for EnableLUA and set the value 0
  • Close the registry editor
  • Restart your computer



Debug

If your tests are not executed correctly or are reporting only failures, this is very likely because your configuration is incorrect or because you used a wrong naming convention for your tests and test cases.


The best way to quickly find out what's wrong is to look at the traces generated by XStudio (or XAgent).
The traces always include the detailed description of what the launcher performs (command line execution, script execution, API calling etc.) to run a test case. So, if you experiment some problems, the first thing to do is to activate the traces and look at what's happening when you run your tests.


Then, try to execute manually in a cmd box the exact same commands.
This will normally fail the same way.
At this point, you needs to figure out what has to be changed in these commands in order to have them run properly.

When you have something working, compare these commands to what's described in the Process chapter above. This will tell you exactly what you need to change.


Most of the time, this is related to:
  • some incorrect values in some parameters of your configuration,
  • the name of your tests,
  • the name of your test cases,
  • the canonical path of your tests
