Performance Tester

Performance Tester

Experience: 7-10yrs

Skills: Loadrunner, Jmeter, Microsoft Dynamics d365 Technology (Azure Devops, CRM, AX)

Role and responsibility:

• Identifies performance test environment requirements and works with the infrastructure, network operations, environment and release teams to setup the environment for effective SLA measurements
• Works with the different project stakeholders to help define and document performance SLAs, requirements and expectations around critical factors such as response time, throughput, transactions/second, concurrent users, CPU utilization, memory, disk, network utilization, thread counts, connection pooling, hit ratios
• Learns the underlying architecture under the COTS products and Enterprise applications utilizing the blueprints and architectural diagrams available within the program
• Develops data driven test scripts and executes performance and load testing of the applications
• Designs and executes daily load tests large system level performance tests
• Collects, analyzes and reports performance testing results to the project, program and business stakeholders
• Reviews the performance test scripts created or modified by peers to ensure compliances with standards
• Collaborates with the test automation team to leverage reusability of existing scripts
• Creates knowledge management related deliverables such as tools related processes and procedures
• Be the performance test specialist

1. Initial Analysis and Presenting Strategy
   1. Capture business goals, critical workflows, and expectations.
   2. Align stakeholders on performance testing scope, goals, and deliverables.
2. Requirements and Planning documents
   1. Define performance metrics (like throughput, latency, error rates)
   2. Identify:
      1. Business-critical paths
      2. Peak transaction rates
      3. Processes for high business impact

1. Environment Setup : Ensure the test environment mimics production like in terms of Hardware, Software & Configuration
2. Script Development :  Using JMeter,  Record key business processes, Parameterize for real-world data, Correlate to handle session data and tokens
3. Workload Simulation : Integrate JMeter with Azure Load Testing to Distribute load across regions, Simulate user behavior at scale & Execute stress, steady load, and spike tests
4. Monitoring and Analysis
   1. Real-time monitoring of: Resource consumption, Latency & Error rates
   2. Collect metrics: Avg/max response times, Throughput & Resource utilization
   3. Diagnose issues: Database locks, Memory leaks & Inefficient code paths
5. Optimization (support developer) collaborate with dev teams to Fix performance bottlenecks, Re-run load tests after fixes & Validate improvements
6. Reporting
   1. Create detailed reports covering: Scenarios, Test environment, Load profiles & outcome
   2. Present findings to stakeholders with focus on: System strengths & Areas requiring improvement
