When trying to open the generated .aiiresult file with Test Studio Result Viewer, I encounter deserialization error. There is also OutOfMemory exception in the Test Studio application log.
I can open the file with a text editor and it is 2 904 185 lines long, which might be causing the issue.
Another related issue is observed when the test list execution tries to generate the .aiiresult file, but it is too large. As a result the file is not created at all.
As a workaround, you can split the test list into two or more test lists to reduce the size of the result file.
