4. Endurance testing
5. Stress testing
These techniques measure the behavior of applications, their working conditions, handle apps with large records and ensure functionality in case the overall number of users increases rapidly.
Q2) Explain Performance Testing?
The process of evaluating the performance of applications under greater load is known as Performance Testing. Basically it’s a non functional testing and is generally done prior to the categorizing the app on production. Actually, this ensures that the app will work fine under all the circumstances and don’t face issues like crashing during the real load. Performance monitoring is a very essential task.

A number of testing related to performance of the apps can simply be handled with this tool. It really doesn’t matter whether its web services or web based apps. Moreover it is capable to handle databases as well as FTP servers.
Q5) How requests are sent to the server in JMeter?
Basically this is done with the help of Samplers. There are several samplers which are present in the JMeter and a few of them that are used commonly are:

Basically it is a very simple process that parameterizes the different types of inputs. This is helpful in using the distinct values for the users.
Q8) What do you know about the correlation?
It is basically a process of enticing the data from the previous calls and then sending it to consecutive request in the form of parameters. It is very helpful in making the scripting easy and the good this is it cut a lot of complexity from the process of handling sessions.
Q9) Tell something about configuration elements?
Customizing the requests that often comes from samplers is an important task in JMeter. The same is performed with the help of configuration elements. They can also be used when it comes to integrating the sampler requests with the data obtained from CSV file.
Q10) What exactly do you know about a Workbench in Jmeter?
Many times while handling the tasks in Jmeter, the need of storing the test elements is felt. Workbench stores them all on temporary basis. In addition to the testing elements, there are certain non test elements which are also present in it. There is a browser in this tool which helps in configuring these elements simply. Keeping anything on the Workbench doesn’t actually mean it is stored in the memory permanently.
