Calling Coded UI Tests from Java using jni4net

[Tony Tonev]

Hi, I'm using this snapshot you posted in a different discussion post:
jni4net-0.8.5.0-snapshot20110711-bin and passing in a .NET 4.0 Coded
UI Test DLL into proxygen, and I get this:

It looks like there are dependencies in the DLL that it can't find?
Maybe dependent Coded UI libraries. Do you know how I can find out
more about what the dependencies are, and how to resolve them?

I have been able to get a simple example .NET DLL to work in Java
through jni4net, so I know that works.

I was able to get it working by adding dependencies in the proxygen
command using -dp. I found the dependencies under References in Visual
Studio (right click, properties, Path has the DLL location). The
command I used was:

proxygen E:\Dev\Java\jni4net\codedUI-test\TestProject2\bin\Release
\TestProject2.dll -wd E:\Dev\Java\jni4net\codedUI-test\working -dp "C:
\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE

\Microsoft.VisualStudio.QualityTools.CodedUITestFramework.dll";"C:

(x86)\Reference Assemblies\Microsoft\Framework\.NETFramework
\v4.0\UIAutomationTypes.dll";"C:\Program Files (x86)\Reference
Assemblies\Microsoft\Framework\.NETFramework\v4.0\WindowsBase.dll"

I probably added more than was needed (just to be safe). When I ran
the build.cmd, it said some of them were duplicate, so I removed those
from the command in the build.cmd, and it worked.

Now to try calling it from Java.

When I tried calling the method from Java, I had to load dependent
libraries like this:

try
{
Bridge.init();
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\
\PublicAssemblies\

\Microsoft.VisualStudio.QualityTools.CodedUITestFramework.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\
\PublicAssemblies\

\Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\
\PublicAssemblies\

\Microsoft.VisualStudio.TestTools.UITest.Common.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\
\PublicAssemblies\

\Microsoft.VisualStudio.TestTools.UITest.Extension.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\

\PublicAssemblies\\Microsoft.VisualStudio.TestTools.UITesting.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\

\PrivateAssemblies\
\Microsoft.VisualStudio.TestTools.UITest.Playback.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File("C:\\Program

Files (x86)\\Microsoft Visual Studio 10.0\\Common7\\IDE\

\PrivateAssemblies\
\Microsoft.VisualStudio.TestTools.UITest.Framework.dll"));
Bridge.LoadAndRegisterAssemblyFrom(new File(".\\lib\
\TestProject2.j4n.dll"));

CodedUITest1 codedUITest = new CodedUITest1();

System.out.println(codedUITest.hello());

codedUITest.CodedUITestMethod1();
}
catch (Exception e)
{
e.printStackTrace();
}

It does print out the hello() string, so I know it's able to call into
the Coded UI DLL. When it gets to "codedUITest.CodedUITestMethod1();"
it launches my application (which is the first step of my Coded UI
test), but then fails with:

Microsoft.VisualStudio.TestTools.UITest.Extension.FailedToLaunchApplicationException:
The following error occurred when this process was started: Object
reference not set to an instance of an object. File:

JniLocalHandle __obj)

at tmp.TempTest.main(TempTest.java:34)

So, it launches the app and then says it failed to launch. I keep
getting "Object reference not set to an instance of an object." Any
idea why this could be? It works fine when run from Visual Studio or
from mstest.exe.

Thanks,
Tony

Hi Tony,

it seems to me you are passing invalid handle. The code which fails is
below (dotPeek).

private UITestControl(IntPtr windowHandle)
: this()
{
if (windowHandle == IntPtr.Zero)
{
throw new ArgumentNullException("windowHandle");
}
else
{
EqtTrace.Verbose("AL : Constructing UITestControl from
windowHandle: {0}", new object[1]
{
(object) windowHandle
});
try
{
this.ScreenElement = ScreenElement.FindFromWindowHandle(windowHandle);
}
catch (SystemException ex)
{
Playback.MapAndThrowException(ex, false);
throw;
}
this.CacheQueryId();

[Tony Tonev]

Hey Pavel,

Thanks for your response. I think you're right, but I'm not sure what's causing it, since I'm not the one calling UITestControl and passing in a null handle. Coded UI does that, and it seems to do it correctly when run from Visual Studio, but from Java through jni4net, it fails. I'm not sure what is different. Any ideas?

Tony

At the second look it seems it starts another process ?
Such process would not contain jni4net of JVM ?
I'm just guessing.

[Tony Tonev]

Yes, it is starting another process to run UI tests on, but that process shouldn't need a JVM since we're only interacting with it through mouse clicks and keystrokes (Coded UI does this).

Thanks again for your response.
