Clicking run button causes exception if no test loaded

Michael Kremser — Wed, 21 Dec 2011 10:45:21 -0000

If you start nunit for example like this:
nunit.exe /run x:\doesnt_exists
and then click the "Run" button (which is enabled after the error message that states that the file could not be loaded), an exception is thrown:

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.
bei NUnit.Util.TestLoader.RunTests(ITestFilter filter)

It seems that the error is in file TestLoader.cs in line 618: Perhaps Services or Services.UserSettings is null. All other calls in RunTests(ITestFilter) don't look suspicious to me to raise that exception or would cause to happen the exception in a different place (like if filter was null - exception would be thrown somewhere in BeginRun or afterwards).

Full strack trace:

System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

Tests can't find their app.config

Andreas Öhlund — Sat, 17 Apr 2010 16:54:02 -0000

When running multiple assemblies or with /domain=multiple tests fails to load configuration settings. This only happens with 2.5.4.10098. With 2.5.3 and below all is fine. This happens regardless of what .net version the tests are using as runtime.

Registry entries and shortcuts remain after install

Jamie Cansdale — Thu, 13 Aug 2009 19:19:19 -0000

Repro:

1) Install NUnit 2.5.1
2) Install NUnit 2.5.2
3) Uninstall NUnit 2.5.1

Actual behaviour:

Registry key:
HKEY_CURRENT_USER\Software\nunit.org\Nunit\2.5.1
and start menu shortcuts are left behind.

Expected behaviour:
Registry entries and shortcuts should be removed.

I think we need to re-GUID all components for each release. With any luck there's an easy way to do this with recent versions of Wix. In the past this hasn't been fun!

Tests with legacy ExpectedException attributes always pass

Jamie Cansdale — Thu, 13 Aug 2009 18:49:13 -0000

Actual behaviour:

The following test when compiled against the NUnit 2.4 'nunit.framework' passes when executed with NUnit 2.5:

[Test, ExpectedException("UnknownException")]
public void ShouldFail()
{
throw new NullReferenceException();
}

Expected behaviour:

Test should fail.

TearDown always throw TargetInvocationException

Exception when click "Run" button

Michael J. Quinn — Wed, 05 Aug 2009 12:51:02 -0000

This was a one-time exception that I cannot reproduce. After closing NUnit GUI and immediately reopening and clicking "Run" again, it did not get an exception (same version of my test suite DLL both times):

Conditions when exception occurred:

1. Test suite had already been loaded and run and test results were showing in the Text Output tab.
2. Made a minor change in my own code.

When I clicked the "Run" button in the NUnit 2.5.1 GUI, I got the following .NET Exception dialog:

Title: "DocMan.NUnit.dll - NUnit"
(DocMan.NUnit.dll is, of course, my test suite DLL)

Message:
----------------
Unhandled exception has occured in your application... blah blah blah

Here are the details:

Assembly Not Loaded (from config dialog)

Michael J. Quinn — Wed, 05 Aug 2009 12:22:05 -0000

In version 2.5.1.9189, I consistently get the following error:

Title: Assembly Not Loaded
MessageBox text:
----------------------------------------------------------------------------------------------------
System.ArgumentException : The net-0.0 framework is not available
Parameter name: framework

For further information, use the Exception Details menu item.
----------------------------------------------------------------------------------------------------

The Exception Details menu shows the following:
----------------------------------------------------------------------------------------------------
System.ArgumentException...
at NUnit.Util.TestAgency.GetAgent(RuntimeFramework framework, Int32 waitTime)
at NUnit.Util.ProcessRunner.Load(TestPackage package)
at NUnit.Util.TestLoader.ReloadTest(RuntimeFramework framework)
----------------------------------------------------------------------------------------------------

This is triggered from the following action:
----------------------------------------------------------------------------------------------------
1. Open the "Project" Menu.
2. Chose "Edit".
3. In the Project Editor dialog box, do nothing other than click the "Close" button.

GUI check boxes out of sync

Michael J. Quinn — Wed, 05 Aug 2009 12:08:54 -0000

http://groups.google.com/group/nunit-discuss/browse_frm/thread/8f2ca046265625a2/fc234e5583ba62fb?lnk=gst&q=quinn#fc234e5583ba62fb

(The text below has been updated since the posting of the thread that is referenced above)...

On a fresh install of 2.5.1 (having 2.4.8 already installed), in the GUI, the check boxes were already visible, but the two buttons ("Clear All", and "Check Failed") were NOT displaying and the menu item (View/Tree/"Show Checkboxes") was not checked. When I selected the menu item, the check mark showed next to the menu item and the buttons showed up (no change on the check boxes since they were already there). Now, toggling the menu item hides or shows BOTH the buttons AND the check boxes together, correctly. Initially, the check boxes were out of sync with the buttons and the menu item.

nUnit Test assembly will not update

Anonymous — Tue, 04 Aug 2009 19:07:41 -0000

I'm running Visual Studio 2008 SP1 Standard Edition on a Windows XP Pro machine. I've created a test project as part of an ASP.Net MVC demo. I added one class to the project, which already had two classes. I ran nUnit and the tests were performed. I added another class to the project. This new class will not appear in the nUnit project. It doesn't matter what I do. I can delete the folders in the shadow copy cache. I can change the version of the assembly and rebuild. I can copy the dll to the shadow copy cache. I can disable shadow copy caching. It doesn't matter. These classes will not appear in the nUnit project. This bug renders the product useless after the first run of the test harness. I ran IL Disassembler, and it sees the new classes.
