How to get LoadRunner iteration number - using global variable? 2008-02-26 13:28:52 I continue explaning about LoadRunner iteration number.Well, how to determine the current iteration number?The first way is to use LoadRunner parameter od 'Iteration Number' type.It is described hereThe second way is to use a LoadRunner global variable.I will explain this approach now. Also, you will see how to define and use global variables.Define a global variableYou can add a new variable definition into vuser_init section of LoadRunner script:Then we will add a variable incrementation and usage into Action section of LoadRunner script. For example, like this:Please, note that LoadRunner does not require using of "extern" keyword.And last step is to open LoadRunner Run-time Settings and to set the desired total iteration count. In my example I set it to 3:That's all! Let's start
LoadRunner web_reg_find function - How to verify web page content? 2008-02-25 05:39:13 When you perform load testing, you have to be fully confident, that your application works correctly. It may be very usefull to check UI of application - is it shown correctly or not.This verification can be performed with 2 ways:Using LoadRunner content verification with web_reg_find function
Running LoadRunner GUI Vusers (QTP or WR scripts)The present LoadRunner tutorial describes content verifications with web_reg_find function. I will explain and show a usage of web_reg_find function, its attributes and result.To get additional information about the seconds approach (running LoadRunner GUI Vusers), please read the article How to execute QTP script from LoadRunner?How to add LoadRunner content verification?Let's start with LoadRunner demo Web application - Web Tours.I will show how Read more:verify
How to minimize/maximize QTP window before the QTP script execution? 2007-12-09 14:41:52 This is very useful feature - minimize QTP window before script
execution. It allows to observe a desktop or an application under test wholly.I will show and describe how to minimize (or maximize) QTP window programmatically - i.e. from QTP script.Also, provided approach can be applied to minimize (maximize) any required window - Browser, Notepad, MS Word or Excel, and so on.There are two ways to minimize QTP window: Using Minimize method of Window objectUsing QTP Application object - QuickTest.Application These methods will contain several lines only and I hope that my explanations will be understandable.So, let's explore! Using Minimize method of Window objectYou can use Minimize method of Window object to minimize QTP window (or any other).Let's see two cases - when a wi
QTP - How to get font size/color, background color and other attributes of controls 2007-12-09 14:37:59 Hello,Today I faced with the following task with QTP (QuickTest Professional) - how to get some attributes (such as: font size, font color, background
color and so on) for any control on a web page?Piece of cake! :)Let's see ways how it can be done.The task: get font size, font color, background color and others possible parameters from the gmail.com start page:The solution:First of all, I tried to use GetROProperty method.I selected "Welcome to Gmail" label with QTP object spy and added them to Object Repository:Well, now I know the class of web control - WebElement.Then, I open QuickTest Professional Help, search for "WebElement Identification Properties" and see that there are not needed properties (font name, font color, size, ...).Help reading shown that it is possible to get needed p
QTP - How to set/get system time and date? 2007-12-09 14:35:15 QTP allows running different types of test. And sometimes, it needs perform time and date manipulations on a computer. In this article, I will show and explain - how to get system time/date and change them.Actually, today's lecture consists of two questions:How to get system time and date?How to set system time and date? Let start training right now :)So, the first section is:How to get system time and date?Actually, this is not difficult task! Use the following functions:Now - function returns the current date and time according to the setting of your computer's system date and time.Date - function returns the current system date.Time - function returns a Variant of subtype Date indicating the current system time.So, the code is very simple. I provide it with a screen shot containin
How to get LoadRunner iteration number - using LoadRunner parameter? 2007-12-09 09:27:02 In some cases, you have to know the current iteration number, which is being executed.It would be great to have something like lr_iteration_number() function. Unfortunately, LoadRunner does not provide that function...In the present article, I will describe how to get a current iteration nunber, which is being executed in LoadRunner VuGen or Controller. Actually, I know two ways how to get current LoadRunner iteration number:LoadRunner parameter of 'Iteration Number' typeGlobal variable, which should be incremented each iterationToday, I will describe and explain first approach (parameter of 'Iteration Number' type). The second one (global variable) I will describe in the next article.Well, we are starting:LoadRunner parameter of 'Iteration Number' typeTo insert new parameter into Lo
Using parameters in Loadrunner VuGen script 2007-12-09 09:25:43 Parameterizing is a powerful thing in LoadRunner!Now, I'm going to demonstrate some tips and uses of them.Well, imagine the following situation...Let's we have created VuGen script
, which emulates the one user:The problem: script runs correctly in VuGen for one user, but it fails for several concurrent users. This happens since we recorded the VuGen script for the specific user:I marked "username" and "password" parameters
and values with red lines.Application under test (AUT) does not allow several sessions of the same user.So, if second concurrent VuGen user logs in to application, he gets an error:The solution: to parameterize the VuGen script.Implementation:Right click on a value we want to parameterize (in our case this is a username - "load1") and select "Replace with a parameter" me
How to perform basic operations on LoadRunner parameters? 2007-12-09 09:25:19 LoadRunner functions and scripts, containing in the present article, will be interested for LoadRunner beginners in the first place.I will describe - how to perform
basic mathematical operations on LoadRunner parameters
:How to convert LoadRunner parameter's value to integer number?How to save integer number to LoadRunner parameter?How to perform mathematical operations on LoadRunner parameter?You can use this article as a LoadRunner tutorial on LoadRunner parameter operations.Well... May I start? :) How to convert LoadRunner parameter's value to integer number?Actually, this is not a difficult task. We have to use 'atoi' function.'atoi' function converts a string to an integer value.Please, see the following code:lr_save_string("543210", "prmCounter");lr_output_message("String value
What are LoadRunner parameter and parameterization? 2007-12-09 09:24:31 This is a simple question - what is LoadRunner parameter? I've reread LoadRunner VuGen User's Guide v9, trying to find the exact definition of LoadRunner parameter. That's strange, but LoadRunner Help does not contain the exact answer on this question.In this article, I will answer basic questions, connected to LoadRunner parameters.I think, LR beginners should study this article carefully :)So, I recommend to read it, if you want to know:the definition of LoadRunner parameterLoadRunner parameter functionshow to create parameter in LoadRunner VuGen scriptwhich types of LoadRunner parameter are availablehow LoadRunner processes parameters - gets and sets their valuesother key concepts, connected to LR parameters OK, let's start.I've recorded Web (HTTP/HTML) simple script on Web Tours
LoadRunner Correlation - How to capture an array of dynamic data with web_reg_save_param function 2007-11-28 07:35:14 Imagine, that server returns the following response:(since blogspot.com doesn't show tags correctly, I'm reluctant to show server response as image) .And we have to capture
dynamic values of all IDs (underlined with green lines). These values can be used later - say, for LoadRunner script correlation.As usual, several solutions exist :) Let's see them:Insert five web_reg_save_param function
s using "Ord=1" (2, 3, ...) attribute:web_reg_save_param ("ID1Value", "LB= value=\"", "RB=\"", "Ord=1", LAST);web_reg_save_param ("ID2Value", "LB= value=\"", "RB=\"", "Ord=2", LAST);web_reg_save_param ("ID3Value", "LB= value=\"", "RB=\"", "Ord=3", LAST);web_reg_save_param ("ID4Value", "LB= value=\"", "RB=\"", "Ord=4", LAST);web_reg_save_param ("ID5Value", "LB= value=\"", "RB=\"", "Ord=5", LAST);Tips: Ple
Using Correlation in LoadRunner scripts - visual tutorial 2007-11-24 17:08:24 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.jsp", "Action=", "Method=POST", "RecContentType=text/html", "Referer=", "Snapshot=t4.inf", "Mode=HTML", ITEMDATA, "Name=TIMESTAMP", "Value=1192177
How to select correct boundaries for web_reg_save_param LoadRunner function? 2007-11-24 16:54:22 I will explain and show - how to select correct boundaries for web_reg_save_param LoadRunner function
.web_reg_save_param is used for LoadRunner script correlation. That's why every load tester should study this function thoroughly, if you wish your scripts work correctly.Imagine that the server returns the following part of HTML page:Note: I will refer to this example later.What boundaries should be used in web_reg_save_param LoadRunner function to capture value of "ID1" (abcde)?The correct left boundary for web_reg_save_param function should be: ID1" value="And right boundary for web_reg_save_param is: "See the solution:Do you know why it is? I will explain in details.To find out the boundaries, we have to see texts located on the left and on the right.What is the text located

LoadRunner - How to record a file saving, performed by user from browser page? 2007-11-01 13:22:45 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 transferr
How to execute QTP script from LoadRunner? 2007-11-01 11:08:29 I'm a big fan of LoadRunner! Really. This is a wonderful tool for load and performance testing.Also, I like QTP. Not love it, just like :) It's powerful enough.That's why I decided to use them together - i.e. execute QTP script
from LoadRunner.I recorded simple QTP script - it just opens Google, performs search, then it clicks 'Next' button, and closes browser:QTP script is quite clear, I hope :)But I faced the questions:Should QTP be installed or not?Can several QTP scripts be executed simultaneously on one computer?Is it required special license for QTP and/or LoadRunner?How to do that - hotw to execute QTP script from LoadRunner?and others questions...It's OK :) I will share my experience and help you to answer these questions!Let's sort them out one after another...Should QTP be
LoadRunner - how to convert a plain text to URL format 2007-11-01 04:32:14 The task - How to convert a plain text string to URL-format
in LoadRunner?Several days ago I faced with a simple task - it was needed to convert a passed parameter (which was in a plain text form) to URL-format. In other words, I had to convert:string "ab" to the same string "ab"string "a b" to the string "a%20b"string "a b_c%" to "a%20b%5Fc%25"and so on ...The cause - Why it was needed?LoadRunner script contained parameters, which should be passed to URL directly. Some my parameters contained special characters like spaces (" "), quotes ("), percentage ("%"), asterisks ("*") and others. To be processed correctly by a browser and a web server, these characters should be translated and passed as their hex-codes.For example:a space character (" ") has hex-code 0x20, so it should be passed as
How to organize user-defined functions into LoadRunner library? 2007-10-26 14:19:05 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.Wel Read more:defined

LoadRunner VuGen scripting - How to automatically download file from server and save it to local disk? 2007-10-19 04:09:57 In my previous article, "How to record a file saving, performed by user from browser page?", I shown that user's activities are not recorded by LoadRunner. This is a rule!LoadRunner records file transferring from server
and does not record file saving.What to do, if you have to save transferred file to local disk?Continue reading, and you will get the solution :)So, Let's start.You can download file from a server with the web_url function.See an example:Image downloading:web_url("logo.gif", "URL=", "Resource=1", "RecContentType=image/gif", "Snapshot=t1.inf", LAST);This code downloads Google's logo image:To save this image as file to local disk, we have to perform these ste Read more:scripting

LoadRunner regular expressions 2008-04-14 02:39:31 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" match
[My money] - March 2008 - $52.25 2008-04-13 23:59:00 As you can see, I use AdSense on my blog.Note: AdSense is an ad serving program run by Google.My readers help me to earn money (not so much as I would wish :) ).That's why I think, that I must share the statistics on money I earned on blog.I plan to share the statistics on monthly basis.Please, see the statistics on last month - March
2008:(click to enlarge the image)As you can see, I earned $52.25 during March 2008.How to spend them?I promise to pay this money to person who will be ready to share how to use regular expressions in LoadRunner. So, investigate this question and will earn $52.25!Do you have others ideas on how to use this money? I'm interested to hear your opinion.Please, post your comments to this blog.Thank you in advance--Dmitry Motevich
