[Solved] Exception when executing a simple test

[Espen Harlinn]

After deciding to split the larger test mentioned in a previous thread into a number of smaller tests I've built a small test consisting of 88 steps - At step 10, while executing a SelectDropDownActionDescriptor 'ByText' with a text string that exists as a choice in the DropDown I get the following:

ArtOfTest.WebAii.Design.Exceptions.ExecutionException: Unhandled exception thrown during automation step execution ---> System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.
   ved System.Text.RegularExpressions.GroupCollection.GetGroupImpl(Int32 groupnum)

Hello Espen Harlinn,

I am suspicious that Windows is running out of virtual memory in its pagefile. Windows automatically starts swapping data to disk when it runs out of physical memory to use. If the disk gets full then you will get out of memory exceptions. Or if the pagefile has filled up to some preset limit then you will get the same out of memory exception.

Can you check the amount of free hard drive space you have? Also can you check your virtual memory settings? To do this follow these steps (these are for Vista):

1. Click on Start
2. Right click on Computer
3. Click on Properties
4. Click on Advances system settings
5. Click the Advanced tab
6. In the Performance group box, click Settings
7. Click the Advanced tab
8. Click Change

Please tell me what the settings are in this Virtual Memory dialog box.

BTW, too little memory and/or too small of a pagefile (which can also be caused by lack of disk space) can cause general slowness in your computer, including the behavior of WebUI Test Studio.
