Virtual Objects in QTP

What is Virtual Object?
 A virtual object is defined by user in QuickTest to recognize any area of your application as an object. Virtual objects enable you to record and run tests on objects that are not normally recognized by QuickTest.
 What is virtual Object Collection?
 A virtual object collection is a group of virtual objects that is stored in the Virtual Object Manager under a descriptive name.
 How to disable virtual Objects while recording?
 Go to Tools-->Options--> General Tab--> Disable Recognition of virtual objects while recording
Check and uncheck this option to disable or enable virtual objects while recording.
 What is the storage location of Virtual Objects?
 If you create any virtual objects automatically those objects will be stored in
QuickTest installation folder\ dat \ VoTemplate
 What is extension of virtual objects file?
 .VOT
 How to use virtual objects on different machines?
 After creation of virtual objects copy QuickTest installation folder\ dat \ VoTemplate Folder to other machines on which you want to use virtual objects.
 What are the limitations and drawbacks of Virtual Objects? 
·         QuickTest does not support virtual objects for analog or low-level recording.
·         Not possible to apply a checkpoint on a virtual object
·         Only by recording we can add virtual objects
·         Not possible to add virtual objects using Object Repository
·         Not possible to spy on a virtual object using object spy
·         Virtual Objects doesn’t support all objects and methods.
·         May not run perfectly on different screen resolutions if a test using Virtual Objects.
·         Virtual object uses the properties Name, Height, Width, X, Y which the properties are having maximum possibilities for frequent change.

JMeter Exceeded Maximum Number of Redirects Error Solution

While running performance test, JMeter allows maximum 5 redirects by default. However, if your system demands more than 5 redirects, it may result in JMeter exceeded maximum number of redirects error. In this post, we have listed down steps to overcome this error. Actual error in JMeter: Response code: “Non HTTP response code: java.io.IOException” Response message: “Non HTTP response message: Exceeded maximum number of redirects: 5” This error is noticed because  JMeter  allows maximum 5 redirects by default and your system may be using more than 5 redirects. You need to increase this count to more than 5 in jmeter.properties file. Follow below steps to achieve this. Navigate to /bin directory of your JMeter installation. Locate jmeter.properties file and open it in any editor. Search for “httpsampler.max_redirects” property in opened file. Uncomment the above property by removing # before it. Change to value to more than 5 Eg. 20. Save the file and restart JMet...

Performance Testing in the Cloud with JMeter & AWS

JMeter is a wonderful tool  to stress test your website and  your application architecture , however if you are trying to simulate many users (>1000) one JMeter instance (=pc) will not be sufficient. You will have to set up a JMeter cluster with multiple machines. JMeter is capable or running  distributed tests , but it comes with limitations. Since most of us don’t have multiple servers laying around somewhere, we usually go to cloud service providers like  AWS , spin up a couple of  EC2 instances  and turn them off whenever we’re done. Here is the problem, JMeter uses  Java RMI (Remote Method Invocation)  to communicate to its slaves, but these connections require all machines to be on the same subnet and this is not feasible with EC2 instances. Below, I explain how to get around this problem using a 3 node configuration in AWS to execute tests. I assume that you have a written the test already and have the .jmx file r...

Difference Between Redirect Automatically and Follow Redirects in JMeter

In this post, we will highlight important difference between Redirect Automatically and Follow Redirects options. These options are found in HTTP Request sampler of JMeter. Knowing the difference will help you decide your performance test strategy. When you check Redirect Automatically option, JMeter will not consider redirect as separate HTTP request. This in turn may result as lower response time in your overall performance test. Whereas Follow Redirect option will consider each redirection as separate requests. This may result in comparatively higher response time. This only has any effect if “Redirect Automatically” is not enabled. To see the difference between these two, record a sample script and run it by checking Redirect Automatically and Follow Redirects option. The second option will generate more requests in your result listener. As you can see from the above post, knowing the difference between Redirect Automatically and Follow Redirects option makes difference i...
