What is transaction instance in LoadRunner?
A LoadRunner transaction instance is used for performance analysis of an existing Transaction you declared in your script. You place the Transaction, by name, into a variable, that can later be used to analyze its status: Get its current duration, status, etc.
What are the parameter types in LoadRunner?
Following are the types of parameter in LoadRunner:
- Custom.
- File.
- Date/Time.
- Group Name.
- Iteration Number.
- Load Generator Name.
- Random Number.
- Unique Number.
What is transaction volume in LoadRunner?
In other words, it can be calculated based on how many transactions are executed over a certain duration of the test and then calculate it for a second. For example, if a vuser executes 6 transactions every minute, then the TPS would be 6 transactions/60 sec = 0.10 TPS.
What is parameterization in LoadRunner?
Parameterization is a method to replace the hardcoded value like application URL, User Name, Password etc. with a parameter which has different input values. Example: You recorded a login page of an application by providing the credentials USER1 and PASS1. When you replay the script, the same credentials are passed.
What is Web_reg_save_param_ex in LoadRunner?
‘web_reg_save_param’ function is used for web protocol (denoted by “web”). This function registers a request to find out the dynamic value based on the boundaries (denoted by “reg”). After registering the request, the next task is to save the dynamic value in a parameter (represented by “save_param” words).
What is LR Auto in LoadRunner?
Syntax: lr_end_transaction(“transaction name”, LR_AUTO/LR_PASS/LR_FAIL);This function stops recording the time between the client and server.
How do I check my VuGen response time?
Visit this group at http://groups.google.com/group/LR-LoadRunner.
…
steps to be followed:
- go to “Average Response time” graph.
- right click on the graph.
- select “set filter/Group by” option.
- suppose you want to see first userid response time, then type 1 in “Vuser ID” section.
- Click “OK” button.
What is transaction in performance testing?
A transaction is a group of requests belong to a particular page. Ideally, each user action has one separate transaction so that response time can be measured individually. Although one transaction can also have multiple user actions. It totally depends on what to measure.
What is block size in LoadRunner?
The size of the block (number of values) can be specified by us or left to VuGen to calculate. For Example, if we have 100 values and 5 Vusers, we can allocate ’20’ values per Vuser (as shown below).
What is transactions per second in performance testing?
It is the same concept that applies if we are testing a web application. If a web app receives 50 requests per second but can only handle 30 transactions per second, the other 20 requests end up waiting in a queue. In short, throughput in performance testing is often expressed as transactions per second or TPS.
What is the difference between Web_reg_find and Web_find?
Q #23) What is the difference between web_reg_find and web_find? Answer: web_reg_find function is processed before the request sent and is placed before the request in the VuGen script whereas a web_find function is processed after the response of the request comes and is placed after the request in VuGen script.
What is Web_set_sockets_option in LoadRunner?
The web_set_sockets_option function configures options for sockets on the client machine. This function supports socket-level replay. In the Web HTML protocol, it supports both HTML-based scripts (Mode=HTML) and URL-based scripts(Mode=HTTP modes).
What is difference between web_reg_save_param and Web_reg_save_param_ex?
‘web_reg_save_param_ex’ has wildcard option with ‘Content Type’ and ‘Request URL’ in the ‘Filters’ section whereas ‘web_reg_save_param’ has wildcard character or digit option in LB and RB attributes.
What are LR functions?
LoadRunner (LR) Functions. These functions are the general LoadRunner functions that are common for all protocols: 1) lr_eval_string(): As already seen, this function returns the input string after evaluating any embedded parameters.
How many types of graphs are available in LoadRunner?
There are 5 graphs on Load Runner.
How do I analyze my LoadRunner results?
Use LoadRunner Analysis to analyze performance test results
- Install Standalone Analysis. In LoadRunner Enterprise, click Open the navigation toolbar and select Download Applications > Standalone Analysis.
- Run a performance test in LoadRunner Enterprise.
- Open the session file for your performance test in Analysis.
What is LR save string in LoadRunner?
you use lr_save_string to convert c string to loadrunner string. If you declare order no in C and use it in your web function, it will not work, in order to work, you need to convert C string to LR string.
How is TPS calculated in load testing?
Calculating Average TPS and Peak TPS metrics Follow
Hourly Transactions Per Second is calculated by dividing total requests count by 3600.
What is throughput in LoadRunner?
What does a Throughput graph represent in LoadRunner? In LoadRunner, a throughput graph provides information about the amount of data (in Bytes or MB) that a Vuser received from the server at any given time. This graph helps to analyse the performance of the application in terms of server throughput.
Which type of a content check is used in LoadRunner?
To answer this question, LoadRunner has a provision called ‘Content Check’. ‘Content Check’ feature verifies the key content in the response of a webpage coming from the server. You can add these checks to the Vuser scripts to ensure the presence of a specific object (Text or Image) on a web page.
What is Threshold Level think time?
57 What is the Threshold level for think time and how can be this changed? The default value is 3. If the think time is less than 3 seconds, VuGen does not generate a think time statements. If you disable this option, VuGen will not generate any think times.
What is Web_url in LoadRunner?
The web_url function is an action function that loads the web page (GET request) specified by the URL argument. (Each Web Action Function in a script causes the browser to display a new web page or frame. All Web Action functions can be recorded by VuGen.) The web_url function does not require a context.
Why correlation is used in LoadRunner?
Correlation is done for the dynamic value or the value returned by server for any request. Parameterization differs from correlation in a way that former takes care of user input data whereas later takes care of data returned by server. Manual correlation and automated correlation follow the same steps.
What is timestamp in LoadRunner?
Timestamp is nothing but it is the number of milliseconds since midnight January 1st, 1970 (also known as Unix Epoch). Overall, we can say that it saves the current time in a parameter.
