What is the difference between performance testing and load testing?
Performance testing is concerned with evaluating the overall system’s performance and collecting metrics such as availability, response time, and stability. Load testing is a technique that verifies whether the application can handle the expected load.
What is a difference between load tests and stress tests?
The key difference is the goal of each: Load tests help you understand how a system behaves under an expected load. Stress tests help you understand the upper limits of a system’s capacity using a load beyond the expected maximum.
What is the difference between test suite and test scenario?
Test Case is a set of actions executed to verify particular features or functionality whereas Test Scenario is any functionality that can be tested. Test Case includes test steps, data, expected results for testing whereas Test Scenario includes an end to end functionality to be tested.
What is meant by stress testing?
Stress testing is a computer-simulated technique to analyze how banks and investment portfolios fare in drastic economic scenarios. Stress testing helps gauge investment risk and the adequacy of assets, as well as to help evaluate internal processes and controls.
Which is better for performance testing JMeter or LoadRunner?
Apache Jmeter is the perfect performance testing tool for web application testing. It offers users various capabilities for performance testing and integration. Therefore, you cannot only evaluate the functional capabilities of web services and apps, but also measure load strength and compatibility across several platforms.
How many threads does JMeter run in Scenario 2?
If there are 30 threads and a ramp-up period of 120 seconds, then each successive thread will be delayed by 4 seconds. In Scenario 2 JMeter will run 1 thread, and after the completion of one thread, the next one will start, and so on 10 times.
What’s the difference between JMeter and loop count?
Most people are aware of the fact that a thread simulates a user and loop-count means the number of times the thread will make request. Let’s walk through the differences. In Scenario 1, 10 threads are used, and the ramp-up period is 10 seconds, so JMeter will take 10 seconds to get all 10 threads up and running.
What’s the difference between parallel and parallel threads in JMeter?
The difference is that in scenario 1, threads may work in parallel, and in scenario 2 each thread starts after the previous one stops. And there is no delay between threads unless you specify them.
