RepoItemInfo.WaitForExists() fails early despite long timeout

[rmathena]

I have a test which passes 90% of the time, but sometimes fails with an error I don't understand. I'm waiting for an item to exist. The timeout is 30s but it fails after 5s with an invocation error. I've checked the timeout for the individual Exists action in the recording, as well at the values associated with the repository item. Is there something else I should be checking? Or is this a bug?

This is Ranorex 9.1.1 on Windows 10 64-bit.

Attached screenshots show the report and the project in Ranorex Studio.

This is the generated code:

Code: Select all

            Report.Log(ReportLevel.Info, "Wait", "Waiting 30s to exist. Associated repository item: 'RootMainWindow.LicenseStatus'", repo.RootMainWindow.LicenseStatusInfo, new ActionTimeout(30000), new RecordItemIndex(15));
            repo.RootMainWindow.LicenseStatusInfo.WaitForExists(30000);

This is from the log:

Hi rmathena,

Try increasing the adapter.functionexecutiontimeout in the solution settings file. This settings is designed to help catch a non-responding/crashed AUT, but in your application, 5 seconds (the default value) may be to short and the application responds shortly after this. While this feature cannot be disabled, you can set it to a much higher value to avoid it from causing this exception (e.g. 60000ms).

Hope this helps!

Hi,

it's strange, because we still get this behaviuor after changing the settings from 5000ms to 120000ms.
Our solution was created with Ranorex 5.3 so we don't have a "Solution items"-folder in the Projects View - should we add it manually?
But we have a "Ranorex.rxsettings" file in the same location as the project-solution-file (*.rxsln). So we changed the value for "adapter.functionexecutiontimeout" and the test still fails after only 5 seconds of waiting, not 120 seconds as expected. Do we have to copy this file with the executionable binaries or are these values compiled in the binariers?

Sorry for this post, it should be easy to solve but I don't have a clue what's going wrong.

Regards,

Hi BcTest,

Since this is an older solution, you can add a solution settings file by clicking the button pictured below. This will generate it in the solution folder and will be copied to the output folder when the test is built.

As long as this settings file is in the same folder as the test executable, the settings from it will be used by the test. Otherwise, Ranorex will fallback on the machine settings file (found in %appdata%). If you prefer to only use a machine settings file, you can delete the solution settings file add the adapter.functionexecutiontimeout setting manually to the RanorexConfig#.xml file and it will be used the same as if it were in the solution settings file.

For more information on Ranorex settings, check out this section of our user guide.

I hope this clarifies everything!

Thanks a lot for the clarification, looks like it works now.
