ISTQB CT-PT 認定試験の出題範囲：

トピック
出題範囲

トピック 1

The Concept of Load Generation: This section of the exam measures the skills of Software Test Analysts and discusses how representative loads are modeled and produced to simulate user or process behavior. It explores methods such as user interface inputs, crowdsourcing, API-based calls, or protocol capture and playback, emphasizing the need for repeatable loads that accurately reflect real-world conditions.

トピック 2

Common Failures in Performance Testing and Their Causes: This section of the exam measures the skills of Performance Engineers and outlines frequent failure modes, including slow responses at various load levels, degraded performance over time, and system crashes under peak conditions. It provides examples of underlying causes such as resource leaks, insufficient capacity, and poor handling of spikes or concurrency, illustrating why robust planning and monitoring are crucial for reliable performance.

トピック 3

Types of Performance Testing: This section of the exam measures the skills of Software Test Analysts and covers various approaches such as load, stress, scalability, spike, endurance, concurrency, and capacity testing. It explains how each type evaluates system behavior under different conditions, helping testers and stakeholders understand how the system handles both expected and extreme usage scenarios.

トピック 4

Testing Types in Performance Testing: This section of the exam introduces the distinction between static and dynamic performance testing. It shows how reviews of requirements, architecture, and code can identify risks before coding is complete, and how runtime checks of resource utilization and response times reveal issues that only appear when the system is in operation.

ISTQB Certified Tester - Performance Testing 認定 CT-PT 試験問題 (Q14-Q19):

質問 # 14
Which of the following is considered a characteristic of stress testing?

A. It focuses on the system's ability to handle transactions over a specific timeframe.
B. It determines the maximum number of transactions a system can handle.
C. It evaluates the system's ability to handle loads beyond its design limits.
D. Considers the system's ability to recover from a sudden increase of loads within the system's limits.

正解：C

解説：
Stress testing is designed to evaluate how a system behaves under extreme conditions, often exceeding its design limitations. The goal is to identify bottlenecks, memory leaks, and failures that occur beyond normal operating conditions.
Option A is incorrect because it refers to resilience testing, which focuses on recovery rather than stress beyond limits.
Option B is incorrect as it describes load testing, which measures performance under expected loads.
Option C is incorrect since determining the maximum transactions is a feature of capacity testing, not stress testing.

質問 # 15
You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.
Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?

A. Preferably during system integration testing
B. Preferably during each phase in the lifecycle
C. Preferably at the end of unit testing
D. Preferably at the end of system testing

正解：B

解説：
Performance testing should be integrated into every phase of the software lifecycle to ensure that critical performance requirements (such as thrust-to-noise ratio) are met early and continuously validated.
Option B (End of system testing) is too late, as issues may be costly to fix at that stage.
Option C (During system integration testing) is useful but not comprehensive enough.
Option D (At the end of unit testing) is incorrect because unit tests do not assess overall system performance.

質問 # 16
Which of the following is the most economical solution to minimize costs and time for performance testing for a high-end production client-server platform?

A. No environment
B. Cloud-based environment
C. Isolated lab environment
D. Mainframe environment

正解：B

解説：
A cloud-based environment is the most cost-effective solution for performance testing. It offers scalability, pay-per-use models, and flexibility, allowing testers to simulate large workloads without expensive infrastructure investments.
Option A (Isolated lab environment) is costly due to hardware maintenance and infrastructure costs.
Option C (Mainframe environment) is expensive and impractical for performance testing.
Option D (No environment) is not a viable option.

質問 # 17
You have run a load test. When examining the metrics, you see that the virtual users experienced many timeouts and excessive wait times. The system throughput metrics exceeded expected results, even during peak times.
Based on your analysis, what conclusion should you draw?

A. Processing speed is too slow.
B. New test data is needed.
C. Network infrastructure should be investigated.
D. Virtual users are exhibiting impatient behavior.

正解：A

解説：
If timeouts and excessive wait times occur, but throughput is high, this suggests that the system is unable to process requests fast enough. This points to slow processing speed due to CPU bottlenecks, memory limitations, or inefficient database queries.
Option A (Network infrastructure investigation) would be relevant if throughput was low or variable.
Option C (Impatient virtual users) is irrelevant; virtual users follow scripted behaviors.
Option D (New test data) does not address the core issue.

質問 # 18
You are managing the testing efforts of an existing distributed system that manages inventories of automobile and light truck tires from multiple warehouses across the country. The system is being enhanced to track incoming restocking shipments at the point of entry to the warehouse and outbound sales shipments at the point of shipment from the warehouse, all of which are executed in real-time. System loads traditionally peak on Mondays due to built-up demand from the previous weekend.
You are preparing a presentation to the business stakeholders, outlining your performance testing strategy.
Which of the following is appropriate to present to this audience?

A. A test plan that includes specific technical specifications for the computing hardware to be used for performance testing
B. Established HTTP response per second goals that will have acceptable minimum, maximum, and average response times
C. A comprehensive list of support staff to be available during performance testing, including key members of the application development team
D. The risks that may exist due to platform differences between the test environment and the production environment

正解：D

解説：
Business stakeholders are most concerned with risks that affect deployment and production stability. The primary risk in performance testing is that the test environment may differ from production, leading to misleading test results.
Option A (HTTP response goals) is too technical for a business stakeholder audience.
Option B (Hardware specifications) is relevant for technical teams, not business stakeholders.
Option C (Support staff details) is a logistical aspect, not a key performance testing risk for business decision-makers.
