ARC Group of Companies Interview Questions and Answers

Performance Testing includes Load Testing, Stress Testing, Endurance Testing, and Spike Testing.

• Load Testing: Evaluates system performance under expected load levels.

• Stress Testing: Tests system performance beyond normal capacity to identify breaking points.

• Endurance Testing: Checks system performance over an extended period to ensure stability.

• Spike Testing: Tests system's response to sudden spikes in load or traffic.

Parameters considered for Performance Testing

• Response time

• Throughput

• Concurrency

• Load

• Stress

Factors for selecting Performance Testing tools include compatibility, scalability, ease of use, cost, and support.

• Compatibility with the technology stack being used

• Scalability to handle the expected load

• Ease of use for testers to create and execute tests

• Cost of the tool compared to the budget

• Availability of support and documentation

• Integration capabilities with other testing tools

• Reporting and analysis features

• Community support and user reviews

Performance testing focuses on speed, scalability, and stability of the system, while functional testing checks if the system meets specified requirements.

• Performance testing evaluates the system's speed, scalability, and stability under various load conditions.

• Functional testing verifies if the system meets specified requirements and functions correctly.

• Performance testing helps identify bottlenecks and optimize system performance.

• Functional testing ensures that the system b...read more

LoadRunner is a performance testing tool used to simulate user traffic on a system to measure its performance under load.

• Allows for performance testing of applications under various load conditions

• Helps identify bottlenecks and performance issues in the system

• Provides detailed reports and analysis of system performance

• Supports a wide range of protocols for testing different types of applications

Endurance testing involves testing the system under sustained load to ensure stability, while spike testing involves testing the system's ability to handle sudden spikes in load.

• Endurance testing is performed to evaluate the system's performance over an extended period of time.

• Spike testing is conducted to assess how the system handles sudden increases in load or traffic.

• Endurance testing helps identify memory leaks, performance degradation, and other issues that may arise ov...read more
