What is ramp up period in JMeter?
Ramp-Up Period (in seconds): Tells JMeter how long to take ramp-up to the full number of threads chosen. For Example: If you set “Number of Threads” to “20”, and “Ramp-Up Period to 40 seconds”, then JMeter will wait till 40 seconds to make all threads up and running.
How do you handle errors in JMeter?
JMeter – Error Handling
- Thread Group: Set Continue on error as we would be handling error logic.
- IF Controller (Try): This verifies if there is failure in requests placed under it, in case of any failure, request flow is stopped and continued to next IF Controller on 4.

What is thread duration in JMeter?
The ramp-up period tells JMeter how long to take to “ramp-up” to the full number of threads chosen. If 10 threads are used, and the ramp-up period is 100 seconds, then JMeter will take 100 seconds to get all 10 threads up and running. Each thread will start 10 (100/10) seconds after the previous thread was begun.

Which is easy to learn LoadRunner or JMeter?
In addition to easier configuration of elements, JMeter doesn’t require adding beginning or ending transaction elements, which LoadRunner does. In LoadRunner, arranging scripts takes up more time and resources, and it is more complex because it requires managing different agents.
What is compare assertion in JMeter?
The Compare Assertion checks the response content or confirms that the response time of all samplers under the assertion scope are equal. The requests and the assertion should be on the same level in the test plan. If TRUE, content of all affected samplers will be checked to confirm it is identical.

What is JMeter sampler?
Samplers in JMeter allows JMeter to send different types of requests to a server. Samplers are the actual requests, JMeter sends to the web server under test. Each sampler (except Test Action) generates one or more sample results. The sample results have various attributes (success/fail, elapsed time, data size etc.)
