How to start Performance Testing project? A practical guide to performance testers Author: NaveenKumar Namachivayam Writer at www.QAInsights.com

2.
● Send business proposal to the clients

3.
● Once your client agreed, start collecting Non-Functional Requirements

4.
● Non-Functional requirements such as Response Time, Throughput, Transactions per sec, CPU usage, Memory, Disk, Network etc.

5.
● Industry standards like Response Time < 5 seconds, CPU and Memory usage < 60%

6.
● Identify Critical Scenarios

7.
● If your client is not able to provide critical scenarios and workload models, we can derive it from the server logs.

8.
● Tools like 123loganalyzer, Deep Log Analyzer, AWstats, Analog etc.

9.
● If no server logs available, analyze the business applications and identify the critical scenarios.

10.
● E.g. Banking application.Critical Scenarios will be1. Login2. Check Balance3. Apply for Loans4. Pay Bills...etc...

11.
● Identify the performance testing tool

12.
● Record your critical scenarios

13.
● Enhance your scripts such as1. Inserting Transactions2. Correlations3. Think Time4. Run time settings5. Browser settings6. Cache settings... etc...then perform a unit test to baseline thescript

14.
● Create Scenarios to execute. Define following:1. Ramp-up period2. Steady State3. Ramp-down period4. Loops5. Mix of transactions6. IP Spoofing...etc...

15.
● Execute the scenario at least three cycles.1. Baseline Test Perform the test with 15-20% of target load2. Load Test Perform with actual load for three cycles. Steady State duration: min. 1 hr3. Stress Test Perform load test and then slowly ramp-up theload step-by-step. Disable Think time and Cachesettings Steady State duration: min. 2-3 hr4. Endurance Test Perform load test for 10-14 hours to identifymemory leaks

16.
● Collect metrics such as1. Response Time2. Throughput3. Transactions per second4. CPU Usage5. Memory6. Disk utilization● Prepare Report● Baseline the report● Compare with Benchmarks and previous results
