Infosys Performance Tester Interview Questions and Answers

Run time setting parameters are values that can be set during test execution to control the behavior of the test.

• Run time setting parameters are used to modify the behavior of the test during execution.

• They can be used to simulate different user loads, network conditions, and other variables.

• Examples include setting the number of virtual users, the duration of the test, and the think time between requests.

Agile is an iterative and incremental approach to software development that emphasizes flexibility and customer satisfaction.

• Agile involves breaking down the project into smaller, manageable chunks called sprints.

• Each sprint involves planning, designing, coding, testing, and reviewing the work done.

• The team works closely with the customer to ensure that the product meets their needs.

• Agile encourages collaboration, comm...read more

The challenge I am facing while scripting is identifying and handling dynamic elements.

• Dynamic elements such as timestamps and session IDs require unique handling

• Identifying and correlating dynamic values across multiple requests can be time-consuming

• Using regular expressions and functions can help in handling dynamic elements

Parameters in result table are the values that are measured during performance testing.

• Parameters can include response time, throughput, error rate, and resource utilization.

• These values are used to analyze the performance of the system under test.

• They can be compared against performance requirements or industry benchmarks.

• Parameter values can be displayed in graphs or charts for easy analysis.

• Examples of parameter val...read more

Non-functional testing is the process of testing the performance, reliability, and usability of a system.

• Identify the non-functional requirements

• Design test scenarios and test cases

• Execute tests and collect data

• Analyze the results and report findings

• Repeat the process until the system meets the non-functional requirements
