How about DON’T EVER REFORMAT MY CODE!!!

If you take your functions from http://www.jds.net.au/tech-tips/scripting-sap-web-dynpro/, add them to a script, and then save the script with another file name, VuGen will reformat the code so that it looks stupid.

I found a bug with VuGen.

When the recording option for “generate web_reg_find functions for page titles” is enabled, and the page title is empty (i.e. “”), VuGen will generate a web_reg_find like this:

web_reg_find("Text=Untitled", 
	LAST);

…even though the word “Untitled” is not on the page.

VuGen 9.5 Recording doesn’t work on 64 bit windows. This sucks because my Controller and load generators are running on 64 bit windows. Analysis also fails. Get with the proram HP!!!

The Replay Log display is horrible. There have been many times I’ve needed to work with raw log data (e.g. identifying large, multi-line boundaries for web_reg_save_param) yet the Replay Log adds a lot of pretty useless meta-data to the display that just gets in the way (e.g. ‘Action.c(280): ‘). Sure that meta-data has its value, occasionally, but I’d really like to see some of the features and display found within the WebProxy tool that comes with HP WebInspect built into Vugen!
Also the highlighting of any line in the Replay Log that contains the word ‘error’ is naive, so many times I find red highlighting on JavaScript code that handles errors but does not actually indicate a manifested error.

Hi Aju, I like your idea of logs in XML format. I gave up on using the VTS a long time ago. Now I prefer to just read/write shared data from a MySQL database. It is much more robust and scalable. I have written some code here: Querying a MySQL database with LoadRunner and Nick has written some functions here: Persistent Data in VuGen with MySQL. Cheers, Stuart.

1. Regex support for web_reg_save_param and web_reg_find functions.
2. Out of the box VTS support.
3. Output logs in XML format.

I’m planning to release that library under an open source license for exactly that purpose.

As for callbacks – ah, I see what you mean there. No, that’s really something HP would have to solve ;-)

Floris, it would be great to share your LoadRunner function library and help all the junior load testers who don’t have an experienced person to write functions for them. :)

The point about allowing callback functions for Content Check rules also applies to the web_reg_global_verification() function. I would find it really useful to be able to write a function that is automatically called whenever the web_reg_global_verification() function matches a known error message.

Cheers,
Stuart.

Some of the problems with C can be mitigated by writing a ’safe to use’ function library. I’ve created something like that which contains common string handling functions but uses parameters to hide all the memory management stuff from the scripter. It also contains a function that will parse an existing parameter and process it as if you had used a web_reg_save_param() call on the original contents.

As for ContentCheck rules: You can use web_reg_global_verification() instead. That method is a lot more flexible too since it means you can turn rules on and off at will.

Having regexp support for web_reg_find() and friends has topped my list too for a while now though, it would simplify life so much ..

There appears to be a bug in LoadRunner 9.5, where if
Runtime Settings > Internet Protocol > Preferences > Options > DNS Caching is set to Yes, then the replay engine will cache the result of the DNS lookup between iterations when “New user on each iteration is selected”.

This is unexpected behaviour, as I would expect a “new user” to have to perform a DNS lookup rather than use the value retrieved by another user.

This can be tested by changing your hosts file halfway though a test.

Cheers,
Stu.
