Responsibilities

Conduct non-functional requirement gathering, assess software application architecture, and formulate a software performance testing strategy.

Utilize user behavior analysis tools, including Adobe Analytics, Splunk, Dynatrace, and Grafana Loki to examine production behavior, generating test use cases for scripting and creating workload models.

Establish the test schedule, identify dependencies, assess risks, and develop mitigation plans.

Specify performance tools, test data, access requirements, and database volume needs.

Craft performance test scripts using JMeter and Load Runner tools to replicate user traversal flows.

Set up monitoring to collect operating system statistics, application metrics, and garbage collection logs, interpreting Java heap memory usage to pinpoint performance bottlenecks.

Execute various performance tests, including baseline, load, stress, volume, and failover, ensuring alignment with business and non-functional requirements.

Monitor application components, servers, and databases using tools: perfmon, vmstat, dstat, nmon, Jvisualvm, Jconsole, and GCViewer during test execution to assess application system health.

Analyze key performance metrics, including Response Time, Throughput, JVM usage, CPU, Memory, and Disk, through monitoring tools Dynatrace, AppDynamics, GCeasy, HeapHero, and fastThread.

Conduct production synthetic load testing using Blazemeter and create micro-services snapshots with the Speedscale tool to automate performance testing within the Kubernetes containerized platform.

Collaborate with application partners to schedule continuous performance testing as part of the Continuous Integration and Delivery (CI/CD) pipeline, automating performance results for prompt SLA deviation resolution.
