Description
Performance testing is used to evaluate the performance, response time, and stability of software applications under load. It helps identify bottlenecks and weaknesses in the system and ensures that the application meets the required standards.
✔Benefits
- Increased system stability.
- Optimized user experience.
- Reduced costs through prevention.
✖Limitations
- Not all load conditions can be simulated.
- Limitations of the testing environment.
- Lack of realistic user data.
Trade-offs
Metrics
- Response Time
The time taken by an application to respond to user requests.
- Throughput
The number of transactions that can be processed within a given timeframe.
- System Utilization
The percentage of system resources being utilized during a test.
Examples & implementations
Load Testing for E-commerce Website
An e-commerce company conducted load testing to ensure their website could handle high traffic during sales events.
Stress Testing for a Mobile Banking App
A bank performed stress testing on their mobile application to identify performance weaknesses before a new update.
Performance Monitoring for Streaming Service
A streaming service implemented monitoring solutions to track performance in real time during broadcasts.
Implementation steps
Define the testing goals.
Create testing plans.
Conduct the tests and evaluate the results.
⚠️ Technical debt & bottlenecks
Technical debt
- Outdated testing methods
- Lack of automation
- Infrastructure issues in the testing environment
Known bottlenecks
Misuse examples
- Using insufficient testing resources.
- Incorrect use of testing scenarios.
- Not including databases in the tests.
Typical traps
- Underestimating testing complexity.
- Confusing load and stress testing.
- Focusing only on technical results, not on user experiences.
