QTP - Capturing tool tips of images
2008-06-01 13:27:00
In my previous post (QTP - How to capture tool tip?) I shown an example on capturing tool tip of Web page link.That solution uses FireEvent("onmouseover") and GetROProperty("text") to get tool tip of a link.Now, I'm going to show how to show how to capture tool tips of images located on a Web page.Actually, the solution is simple.To capture a tool tip of an image, we can get value of "alt" Run-time Object property with GetROProperty("alt") function:Browser("brw").Page("p-g").GetROProperty("alt")Let's verify this code in practice. For example, let's check tooltips from Wikipedia Main page:I've prepared QTP script, which gets all image from this page and checks their tooltips ("alt" property):Dim descImage, listImages, attrAltText, attrSrcTextBrowser("Main Page - Wikipedia,").SyncBrowser("Main- Page - Wikipedia,").Page("Main Page - Wikipedia,").Sync' Create description for all images on a Web page.' For that we use "html tag" property and its value "IMG"Set descImage = Description...

How to save parameter value to other parameter in LoadRunner?
2008-06-01 11:36:00
One my reader asked me - "How to save parameter value to other parameter in LoadRunner?". OK, there is a simple solution.To save parameter value to other parameter you have to:Evaluate value of initial parameterUse lr_eval_string LoadRunner function.Save the evaluated string to a second parameterUse lr_save_string LoadRunner function.Please, check the following code:// save string value to initial parameterlr_save_string("some string value", "prmStr1");lr_output_message(lr-_eval_string("Value of prmStr1: {prmStr1}"));// save the evaluated value to second parameterlr_save_string(lr_eval-_string("{prmStr1}"), "prmStr2");lr_output_message(lr-_eval_string("Value of prmStr2: {prmStr2}"));Let's execute this code and check the result:(click the image to enlarge it)As you can see, both parameters (prmStr1 & prmStr2) have the same values - "some string value".So, we assigned the parameter value to other parameter successfully.Related articles:How to perform basic operations on LoadRunner p...

How to get unique file name in LoadRunner?
2008-05-31 21:45:00
In my previous LoadRunner VIDEO post, I shown and explained how to record PDF file saving in LoadRunner.The provided code works correctly in LoadRunner VuGen or in LoadRunner Controller for one concurrent user. Here it is://Truncate to zero length or create file for writing.fp = fopen("c:\temp\_file.pdf","wb")-;//Process the data ... //Write the data to an output file.fwrite(bufData, nSize, 1, fp);If you try to run this code with several concurrent users, all of them will try to create the same file and write to it. As a result, this will led to the error.How to resolve this problem?Each user has to get unique file name and create a file with the unique name .Now, I'm going to show - how to generate unique file name in LoadRunner.The first step is to get a timestamp as a part of file name.The timestamp consists of:date (month, day, year)time (hours, minutes, seconds, milliseconds)You can use the following simple code to get a full timestamp without milliseconds:lr_save_datetime("-...

One LoadRunner user asked me - How to record PDF file saving in LoadRunner?Earlier, I explained that LoadRunner does not record client side activities!That means, that LoadRunner records PDF file transferring ('cause it is a network activity) and does not record PDF file saving (which does not generate any network traffic).In some case, we need to save PDF (or other) file on local disk and process it (edit, parse, or compare with 'etalon' file).The present LoadRunner video tutorial explains how to record PDF file saving in LoadRunner.How to record PDF file saving in LoadRunner?This is a first LoadRunner script from the above LoadRunner video tutorial.Note: this script is based on HP's article #11766 - How to verify download of a file in Web scripts (login to HP required to access).int fp;long i;web_url("writings.html","URL=-http://www.testing.com/writings-.html","TargetFrame=","Resource-=0","RecContentType=text/html",-"Referer=","Snapshot=t1.inf","M-ode=HTML",LAST);//Trunca...

LoadRunner regular expressions
2008-04-15 06:10:00
I have a real challenge for LoadRunner specialists, professionals, and gurus.I would like to start new public investigation on LoadRunner regexp (regular expressions).The reward is $52.25.As you know, LoadRunner supports limited and 'light' regular expressions. These are special text flags of web_reg_save_param function to support 'light' LoadRunner regular expressions:/DIG interprets the pound sign (#) as a wildcard for a single digit.For example, "te##xt" matches for "te23xt", and doesn't match for "text" and "te234xt"./ALNUM interprets the caret sign (^) as a wildcard for a single US?ASCII alphanumeric character.There are three syntaxes: ALNUMIC to ignore case, ALNUMLC to match only lower case, and ALNUMUC to match only upper case.For example, with ALNUMLC flag enabled, "te^^xt" matches for "tenext", and doesn't match for "teNext" and "teneoxt".The task is simple:How to use real regular expressions in LoadRunner with C language?Note: you can use real regexps with VBScript o...

Assume, you work and work in LoadRunner, create and create scripts.Eventually, you face the situation when your code is duplicated in many scripts. This is a wrong way! Take my word for it :)I will show - why it is and how to struggle against it.Duplicated code is an evil, because:If you fix/modify a duplicated code, you have to edit each occurrence of this code.It needs add debug messages into duplicated code, you have to add debug functions into each occurrence of this code.If you decide to change the algorithm, implemented in a duplicated code, you are reluctant to find and edit it in each occurrence of this code. If you have tens or hundreds VuGen tests, containing diplicated code, the support can become a nightmare. Rework will cost too much!!! You must avoid it from the beginning.Well, what to do?You have create a user-defined library.

LoadRunner - How to record a file saving, performed by user from browser pa
2007-10-13 23:22:00
The problem:This is a frequently asked question - why file downloading from a browser page (right mouse click, then "Save Target As...") was not recorded in LoadRunner VuGen script?The difference between functional and load testing:Actually, LoadRunner records a file transferring only, not downloading!This is the principal difference between functional and load testing! I will describe it.Functional testing is done from a user's viewpoint.What does a user see? It sees windows, dialogs, UI cotrols.For example, user can see downloaded html-page in a browser, or as plain text in a telnet session.In this case, data transferring is the same (HTTP protocol), while data representation varies (browser or telnet session).LoadRunner performs Load testing, i.e. it records and emulates data transferring between client and server. Data transferring only, not data displaying for user!For the above example, html-page can be downloaded directly from web-server. Another variant - page can be downlo...

Today, I will explain - what is LoadRunner correlation and how to perform it.In my humble opinion, correlation is the key concept of LoadRunner. So, strong understanding of correlation is mandatory requirement for any test engineer, if he plans to be LoadRunner professional or even guru :)Example from a real practice:I recorded LoadRunner script for a web server, which contained two special fields - timestamp and checksum:web_submit_data("rms.j-sp", "Action-=http://eprumossd0010:8400/RMS/-jsp/rms.jsp", "Method-=POST", "RecCon-tentType=text/html", "Refere-r=http://eprumossd0010:8400/RMS-/html/testFramework.html", "Snapsh-ot=t4.inf", "Mode=H-TML", ITEMDAT-A, "Name=T-IMESTAMP", "Value=1192177661211", ENDITEM, "Name=C-HECKSUM", "Value=715E19300D670ED77773BBF0-66DAAAE28...
