JMeter Interview Questions for Freshers
1. How requests are sent to the server in JMeter?
JMeter Interview Questions for Freshers : Basically, this is done with the help of Samplers. There are several samplers that are present in the JMeter and a few of them that are used commonly are:
- Junit request
- JDBC request
- HTTP request
2. What do you know about JMeter features?
Extensibility, portability as well as robustness are some of its key features. It is a Java-based approach, and thus it supports all applications based on the same. It is possible for the users to have a final outcome in graphical or tabular form. Test scripts can be created very fast and this is because of the playback feature that JMeter is equipped with. Also, a user needs not to worry about the protocols that can be tested through this tool.
3. Explain the Process of Parameterization?
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.
4. 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 requests 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.
5. Tell something about configuration elements?
Customizing the requests that often come 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 the CSV file.
6. What exactly do you know about a Workbench in Jmeter?
Many times while handling the tasks in Jmeter, the need for storing the test elements is felt. Workbench stores them all on a temporary basis. In addition to the testing elements, there are certain nontest elements that are also present in it. There is a browser in this tool that helps in configuring these elements simply. Keeping anything on the Workbench doesn’t actually mean it is stored in the memory permanently.
7. Name an element in the JMeter that is powerful in representing a group of virtual users that are responsible for performing different operations.
The name of this element is Thread Group
8. Explain the Ramp-up period?
When it comes to testing the loading of an app, only a few users are considered then all for effectively studying the behavior of the app. This also derives a lot of useful information to know the overall performance of the app. Of course, it takes some time in making all the users in the running state. This time period is generally called the Ramp uptime. It is different from different apps depending on the overall number of users, data, and several other factors.
9. What are the benefits of using JMeter?
It is a very reliable told that always makes sure of error-free results. Its compatibility with all the apps makes it the best in performing its task. JMeter is an open-source tool and thus users need not worry about the cost. Learning and using this tool is not at all a big deal. In addition to this, customization of the JMeter tool to fit the exact needs is not at all a big deal. There are several tutorials and online communities to help that can help to eliminate any problem that declares its presence during the process.
10. What are the roles of Listeners in JMeter. Can you name a few of them?
Well, the prime role of listeners in the JMeter is to save the outcomes of tests after viewing the same. Basically, they are also very useful when it comes to graphical analysis as well as tabular analysis of the outcomes. A few of the commonly used Listeners are:
- Aggregate Graph
- View results tree
- Aggregate report
11. Name a few timers in JMeter. For what purpose they are considered?
Some of the common timers used in the JMeter are:
- Synchronizing timer
- Uniform random timer
- Gaussian random timer
- Constant timer
Many times test gassing of a thread needs to be stopped for a specific time. Timers are used for the same purpose. They are capable to simply simulate the real user thinking time.
12. What do you mean by the Rendezvous point?
Spike testing is a very common approach in Jmeter. Actually, there are certain tasks that are associated with it. The prime task of the rendezvous point is to managing spike testing without creating any issue. Actually, the synchronizing timer is considered along with it to perform this task. You need to wait for the time till all the active users reach a value that is assigned during the load test.
