TestExecute Asynchron action fail on VM

Question

Running a DelphiScript test on TestComplete 14.30.3743.7 x64 is passing, while running the same script on TestExecute 14 and VM (Windows Server 2016 64-bit OS,16 GB RAM, 4 cores 2.10 GHz), test will failed with Asynchronous object call failed.

Any idea?

It was my mistake; the environments were different, having different databases, which lead to a different behavior of the tested application. So, I cannot assume anymore TesteExecute and TestComplete are acting different, except the play time, which is faster at TE.

With other words, this topic it has no point in my view, and for this specific environment which I mentioned above.

Hi,
&nbsp;
In addition to everything written by Robert:
&nbsp;
&gt;&nbsp;function aRunAsyncAction [...]
In a most cases human user works synchronously. Likewise do most of tests.
Actions like&nbsp;PerformClick, Keys,&nbsp;BringToFront are also synchronous.
Most of scripting languages (including DelphiScript) are synchronous. (Funny case with Javascript &amp;colon; while it was created as asynchronous one, practically all test frameworks force it to synchronous mode :) )
The primary reason for the&nbsp;.CallObjectMethodAsync() method in TestComplete is to handle cases when some object does not exit its event handler until this event is handled. E.g. when the modal window does not return control until it is closed, causing deadlock when been controlled by test automation software.&nbsp; .CallObjectMethodAsync() method is the only means in this case and this is practically the only case when it should be used.
So, unless you can provide a reason why you are trying to implement asynchronous code in synchronous environment I would recommend you to not use&nbsp;.CallObjectMethodAsync() method and replace it with regular synchronous calls.

Hi Alex,&nbsp;Unfortunately, TestComplete won't work without the asynchron method on that specific modal window. On the other hand TestExecute seems not to work with asynchron method for the same modal window. I should probably create different scripts for each testing tool, which if you ask me, is not reasonable.PerformClick is synchronous for as long as a modal window will not follow, when the case is changing, and an asychron method has to be use.However, I can understand Robert's explanation that TestExecute is faster than TestComplete at runtime, and this is a reason to "loose" the asynchron object.It is nothing wrong with the asynchron method I've posted here, since is running for years with TestComplete, with the same script, and on the same desktop application-the trouble is, we've just moved to TestExecute where it seems to be a different environment, and will take a bit more to get familiar with its behavior.

Without knowing what the code is, can't say for sure. Most likely, there's something different on the TestExecute VM that is not accounted for on the development machine, most likely something to do with timing where an object does not exist in time.

Please post the code where the error occured.

Here is the function. I don't think is something wrong with it, since on TestComplete is doing well.

function ExportDivision

begin
TerminateAction:=aRunAsyncAction(bExportaDiv, 2, '', false, ConfAc);
comboxFileNameExpDiv.SetFocus;
comboxFileNameExpDiv.keys(PathName);
bSaveExportFileDiv.keys(' ');
bConfirmYesReplaceFileDiv.keys(' '); --it will run this line and at the next line will fail
CheckAction(TerminateAction,true);
end;

CheckAction is not a TestComplete function I recognize so I'm guessing it's something custom written by you or someone on your team.&nbsp; can you share that code?&nbsp; I'm guessing it's something in there that's causing the failure.
