Background and Challenges

Performance testing involves simulating massive user concurrency to evaluate system capacity, load handling capability, and high-concurrency processing performance, as well as determine the required hardware and software configurations to meet performance requirements.

Performance Testing Process

The performance testing process includes:

Develop a test plan based on the system's actual architecture and current performance characteristics.

Define a test model according to specific requirements, analyzing key parameters such as data volume, concurrent users, response time, and configuration settings of the target system.

Design test scenarios for peak business periods based on real-world usage patterns and transaction loads.

Create test scripts based on specific protocols (e.g., HTTP, HTTPS, Socket) and application interfaces (APIs).

Execute load tests using designed scenarios; monitor system behavior and analyze any anomalies during test execution.

Analyze performance metrics and generate a comprehensive performance test report.

Analyze the system topology and establish a monitoring model.

Identify monitoring sampling points and define data collection metrics based on the system topology diagram.

Enable effective data sampling and analysis during load injection phases.

Define Performance Requirements

Determine stress testing objectives based on historical transaction volumes and projected future business growth

Identify Peak Loads:

Identify peak scenarios and critical business functions by analyzing transaction volume rankings.

Detect peak loads by monitoring CPU utilization, I/O operations, and network throughput

Business Scenario Analysis

Identify distinct business scenarios through comprehensive analysis of user workflows and transaction patterns.

Apply load to each business scenario to uncover performance bottlenecks and mitigate potential risks.

Define the System Data Model

Generate representative test data based on current and forecasted business data volumes to ensure test accuracy and realism.

Record or Author Performance Scripts

Use performance testing tools such as PerformanceRunner to record or manually develop test scripts.

Script recording is supported for common protocols including HTTP, HTTPS, and Socket.

Create Test Scenarios

Build test scenarios using test scripts based on prior business scenario analysis.

Execute test scenarios and monitor test data in real time.
