What is Performance Testing - Advanced Level

For advanced testers, performance testing goes beyond the basic validation of response times and throughput. It involves a more comprehensive and detailed approach to evaluate system performance under various conditions. 

Here are some aspects of performance testing that advanced testers typically focus on:

  1. Performance Test Planning: Advanced testers excel in creating well-defined performance test plans. They analyze the application architecture, identify critical scenarios, determine performance goals, and select appropriate performance testing techniques and tools.

  2. Performance Test Design: Advanced testers design complex and realistic performance test scenarios that accurately mimic real-world usage patterns. They incorporate various factors like user profiles, data volumes, transaction mix, and think creatively to cover different testing objectives.

  3. Performance Test Execution: Advanced testers execute performance tests with precision and accuracy. They monitor system resources, collect performance data, analyze metrics in real-time, and identify potential bottlenecks or performance issues early in the testing process.

  4. Advanced Performance Testing Techniques: Advanced testers are proficient in using advanced techniques such as stress testing, spike testing, endurance testing, and capacity testing. They leverage these techniques to uncover system limitations, assess scalability, and identify performance degradation points.

  5. Performance Test Analysis: Advanced testers possess strong analytical skills to interpret performance test results effectively. They perform in-depth analysis of metrics, pinpoint performance bottlenecks, and provide valuable insights and recommendations for optimization and improvement.

  6. Performance Tuning and Optimization: Advanced testers collaborate with development teams and system architects to optimize performance. They suggest code-level optimizations, database query tuning, caching strategies, and other techniques to enhance system performance.

  7. Non-Functional Testing: Advanced testers understand that performance testing is part of a broader non-functional testing landscape. They have expertise in related areas such as load testing, reliability testing, scalability testing, and security testing. They can incorporate these aspects into the performance testing process.

  8. Test Automation and Tooling: Advanced testers leverage automation frameworks and performance testing tools to streamline test execution, data collection, and result analysis. They have experience in scripting performance tests, integrating tools, and customizing test environments.

  9. Performance Monitoring and Profiling: Advanced testers are skilled in using performance monitoring and profiling tools to monitor system behavior during load tests or real-time production usage. They analyze performance metrics, identify performance hotspots, and suggest optimizations based on empirical data.

  10. Reporting and Communication: Advanced testers excel in creating comprehensive performance test reports that communicate findings, recommendations, and insights to stakeholders effectively. They understand how to present complex technical information in a clear and actionable manner.

In summary, advanced testers go beyond the basics of performance testing and bring a deep understanding of performance testing principles, techniques, tools, and methodologies. They have the expertise to conduct complex performance tests, identify critical performance issues, and provide valuable recommendations for optimizing system performance.

Pacing Time in LoadRunner

What is Pacing? Where and why to use it? -Pacing is the time which will hold/pause the script before it goes to next iteration. i.e Once the   Action   iteration is completed the script will wait for the specific time(pacing time) before it starts the next one. It works between two actions. eg, if we record a script there will be three default actions generated by the Load Runner:   vuser_init, Action   and   vuser_end,   the pacing will work after the   Action   block and hold the script before it goes to repeat it. The default blocks generated by LoadRunner is shown below: Actions marked in Red Now we know what is pacing and we use it between two iteration. The next question comes to mind is why we use pacing: Pacing is used to: To control the number of TPS generated by an user. To control number of hits on a application under test.     Types of Pacing: There are three options to control the pac...

How to troubleshoot high Memory utilization during performance testing

 When troubleshooting high memory utilization during performance testing, it's important to identify the underlying causes and take appropriate steps to address the issue.  Here are some steps to troubleshoot high memory utilization: Monitor Memory Usage: Use performance monitoring tools to track memory usage over time. Monitor both physical and virtual memory (RAM) to identify if memory consumption is exceeding available resources. Identify Memory-Intensive Processes: Identify the specific processes or components that are consuming a significant amount of memory. Performance monitoring tools can help you identify the memory-hungry processes. Look for any particular application, service, or module that stands out in terms of memory usage. Analyze Code and Memory Allocation: Review your application's code and algorithms to identify any memory leaks, inefficient memory allocation, or excessive object creation. Look for areas where large amounts of memory are being consumed unnec...
