Auctus Advisors Test Engineer Interview Questions and Answers

White box testing is testing the internal structure of the system while black box testing is testing the external behavior of the system.

• White box testing is also known as clear box testing or structural testing.

• It involves testing the code, architecture, and design of the system.

• Examples include unit testing, integration testing, and code coverage analysis.

• Black box testing is also known as functional testing or behav...read more

Scripting challenges include dynamic parameters, correlation, and handling complex scenarios.

• Dynamic parameters require capturing and replacing values in scripts

• Correlation involves identifying and handling dynamic values in responses

• Complex scenarios require careful planning and scripting to ensure accurate simulation

• Debugging and troubleshooting can be time-consuming and require attention to detail

I have worked on various monitoring tools such as JMeter, LoadRunner, and Gatling.

• JMeter for load testing web applications

• LoadRunner for performance testing client-server applications

• Gatling for stress testing and real-time monitoring

A performance test plan is a document that outlines the objectives, scope, approach, and resources required for conducting performance testing.

Workload modeling involves designing a realistic simulation of user behavior and system usage.

• Identify user personas and their typical actions

• Determine the frequency and duration of each action

• Consider peak usage times and seasonal variations

• Use real-world data and historical trends to inform the model

• Validate the model through testing and iteration
