Concurrency testing in Testcomplete

Hi,  Can Testcomplete handle concurrency testing? An application in my company could be opened as more than one instance, and I need to test that doing some actions on one instance will ...

    Hi Kai,



    Definitely, I did not have an idea to remap everything for one of the DataFlows. :) The idea was to change namemapping for just DataFlow1 so it used not only process name, but also ProcessIndex set to 1.



    Hovewer, if you are saying that you may have more than two dataFlow processes running and do not mix their usage in the test code, but do something with first instance and than do something with another instance, I think that your idea should work and be even better.

    In order to implement it, you should:

    a) Make a backup of the current NameMapping.tcNM file;

    b) Delete one of the namemapped DataFlow processes with all its children;

    c) For the remained DataFlow process, select it in the namemapping tree and for the ProcessIndex row on the right click the ellipsis button (the button with three dots);

    d) In the endsuing dialog select Project Variable for the Mode field and select ApplicationIndex variable from the Variable drop-down;

    e) Save NameMapping changes.



    Now, I believe that TestComplete will select correct process instance after you set proper value to the Project.Variables.ApplicationInstance variable in your test code.

Hi, robert



Thanks for the reply.



I made some research on Distributed Testing and LoadUIWeb, but neither of them is what I wanted.



I put the hurdle as follows in a more detailed manner:

In Object Browser in TC, I have the following structure

Sys

     Process("PalantirDataflow", 2) (let's call it Dataflow 2)

     Process("PalantirDataflow") (let's call it Dataflow 1)



PalantirDataflow is a product in my company, I mapped loads of controls in this product, and functions are all based on the mapped name.



Now I need to do a concurrency test, e.g. Action A: delete a document in Dataflow 1.  Action B: check the document is deleted in Dataflow 2. These two actions are executed in the respective instance on one computer, and the two instances of Dataflow in the computer keep open all the time.



The issue is when I do the Action A, TestComplete gives me a warning message: ambiguous recognition of the tested object. It makes sense since there are two instances opened. So, is there a way that I could specify which instance I am going to deal with?



I tried a method that, since the only difference between the two instances is the index, so I set the index of the instance as a project variable. The exploratory test is as follows:




Project.Variables.applicationIndex = 1

Sys.refreshmappinginfo (also tried dataflow.refreshmappinginfo, neither works)


Do Action A


Project.Variables.applicationIndex = 2

Sys.refreshmappinginfo (also tried dataflow.refreshmappinginfo, neither works)


Do Action B



Is there a method could overcome this hurdle?



Cheers.

Kai
