Performance test planning in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of performance test planning?

The main goal is to prepare a clear strategy to test how well a system performs under expected and peak loads, ensuring it meets speed, stability, and scalability requirements.

Name three key elements to include in a performance test plan.

1. Test objectives (what to measure)<br>2. Test environment setup<br>3. Load and stress scenarios

Why is defining realistic user load important in performance test planning?

Because it helps simulate real-world usage, making sure the system can handle actual user traffic without slowing down or crashing.

What role does the test environment play in performance testing?

The test environment should closely match the production setup to get accurate results that reflect real user experience.

How do you decide on performance test metrics to track?

Choose metrics like response time, throughput, error rate, and resource usage based on what matters most to the system’s users and business goals.

What is NOT typically part of performance test planning?

A Writing user interface design

B Defining test objectives

C Setting up test environment

D Choosing load scenarios

User interface design is unrelated to performance test planning, which focuses on testing system speed and stability.

Which metric measures how many requests a system can handle per second?

A CPU usage

B Response time

C Error rate

D Throughput

Throughput measures the number of requests processed per unit time, often per second.

Why should the test environment match production in performance testing?

A To save money

B To get accurate test results

C To test new features

D To reduce test time

Matching the production environment ensures test results reflect real user conditions.

What does a stress test check in performance testing?

A System behavior under peak or extreme load

B System behavior under normal load

C User interface usability

D Security vulnerabilities

Stress testing checks how the system behaves under extreme or peak loads beyond normal usage.

Which is a realistic user load scenario example?

A Testing without any users

B 1 user logging in once a day

C 1000 users logging in simultaneously during peak hours

D Random clicks with no pattern

Simulating peak user activity helps test system performance under real conditions.

Explain the steps you would take to create a performance test plan for a new web application.

Think about what you want to test, where, and how.

Describe why it is important to choose the right performance metrics and how they help in evaluating system performance.

Metrics are like measuring tools for system health.
