Interview Questions on Katalon Studio

Katalon Studio is a popular test automation platform that offers a range of features for efficient testing and debugging. In this article, we will explore some common interview questions related to Katalon Studio, along with their answers.

Q #8) Explain the difference between Gaussian and Poisson Timers.

Both Gaussian and Poisson Timers work on a mathematical formula with some constant delay and additional offset. The number of config elements or processors and it also depends on whether you are using GUI/Non-GUI Mode. Other factors that impact thread count are the number of components in your test plan, i.e., the complexity of your application.

Q #7) What are the maximum recommended threads on a single system?

It depends on the hardware configuration of your system, which includes a processor, JVM, allocated memory (-Xmx), etc. The number of threads that can be handled by a system is limited and varies based on the system's specifications.

Q #6) What are the different ways of Data Parameterization in JMeter?

Data Parametrization makes the scripts reusable where values are not required to be hardcoded for the same request with different parameters. Below is the data parametrization that is supported in JMeter:

* They can be used to extract some fields from the server response and store them in variables.

* Pre-Processors execute before the main sampler and can change the scope of the sampler, whereas Post Processors execute after the main sampler and are applicable to all samplers in the same scope of Test Plan.

Q #5) What are the types of processors in JMeter?

Basically, there are two types of processors in JMeter, namely Pre-Processor and Post Processor. Regular Expression is used in both Pre-Processors as well as Post Processors.

Q #4) What is the use of Regular Expression in JMeter?

Regular Expression is used for extracting some values dynamically from responses. These values can be used in the subsequent request or can be saved for reporting purposes.

Q #2) Does JMeter simulate actual browser behavior?

No, JMeter does not support actual browser behavior. Unlike any browser, JMeter works on levels of protocols and does not execute JavaScript present in HTML web pages.

Q #1) Explain the architecture of JMeter.

Jmeter is a Java-based open-source application that is basically designed for the purpose of Load Testing. It supports all major protocols that are supported in Load Runner.

In conclusion, Katalon Studio is a powerful test automation platform that offers a range of features for efficient testing and debugging. Understanding these interview questions will help you prepare for your next job interview and demonstrate your knowledge of Katalon Studio.
