The scope of performance testing is established during the test planning phase. During this phase, testers define the objectives, resources, schedule, and scope of the testing activities. This includes identifying the specific performance requirements, determining the test environment, and outlining the test strategy. According to ISTQB guidelines, effective test planning ensures that the performance testing efforts are aligned with the project goals and stakeholder expectations, setting a clear direction for subsequent testing activities.

To calculate the number of departing passengers accessing the front-end only once to check in per hour, we follow these steps:

Total Departing Passengers in January:

465,000 passengers transported throughout January.

Duration of Operations in January:

Operating hours: 07:00 to 23:00, which equals 16 hours per day.

Total days in January: 31 days.

Total operating hours in January: 31 days * 16 hours/day = 496 hours.

Passengers Per Hour:

Total passengers: 465,000.

Total hours of operation: 496 hours.

Passengers per hour: 465,000 passengers / 496 hours = 937.5 passengers/hour.

Passengers Accessing Only Once for Check-In:

30% of departing passengers reconnect for a boarding pass, which means 70% access only once.

Passengers accessing only once: 70% of 937.5 passengers/hour = 0.70 * 937.5 = 656.25 passengers/hour.

Given the available options, the closest correct value isC. 625.00 departing passengers / hour.

Generating load through the User Interface (UI) is essential to replicate a real production environment accurately. This approach simulates real user interactions with the system, providing a more realistic assessment of how the system performs under actual usage conditions. According to ISTQB standards, using the UI to generate load helps identify performance issues that users might experience, ensuring that the test results are relevant and actionable.

To determine how many departing passengers access the front-end per hour, including those reconnecting:

Total Departing Passengers in January:

465,000 passengers transported throughout January.

Duration of Operations in January:

Operating hours: 07:00 to 23:00, which equals 16 hours per day.

Total days in January: 31 days.

Total operating hours in January: 31 days * 16 hours/day = 496 hours.

Passengers Per Hour:

Total passengers: 465,000.

Total hours of operation: 496 hours.

Passengers per hour: 465,000 passengers / 496 hours = 937.5 passengers/hour.

Including Reconnecting Passengers:

30% of departing passengers reconnect for a boarding pass.

Reconnecting passengers: 30% of 937.5 passengers/hour = 0.30 * 937.5 = 281.25 passengers/hour.

Total front-end accesses per hour: 937.5 + 281.25 = 1,218.75 passengers/hour.

Given the available options, the closest correct value isA. 1,425.00 departing passengers / hour.

Ramp-up in performance testing refers to the phase where the number of virtual users is gradually increased to simulate the increase in load on the system. This is essential for determining how the system behaves under varying levels of stress. The correct description of the ramp-up concept aligns with option C, which involves increasing the number of concurrent users to simulate a transition from a steady state to a higher load scenario.

When presenting to technical stakeholders, it is crucial to provide detailed information about the setup, preparation, and execution of the performance test.

Option Atalks about the test environment and passenger data logistics, which, while technical, is not as focused on the specific setup for the spike test.

Option Bdetails the specific environment setup by the systems manager and the preparation steps, which are highly relevant to technical stakeholders who will be involved in or overseeing the technical aspects of the test.

Option Cagain focuses on budget and timeline, not technical details.

Option Dis more high-level about the purpose of the test, which is not as relevant for technical stakeholders who need the specifics of the test setup.

Thus, Option B is the best fit as it provides the necessary technical details for the spike test environment and preparation steps.

In the testing process, specific test conditions for performance testing are identified during the Test Analysis phase. This phase involves reviewing and analyzing the test basis, such as requirements, architecture, and design, to identify the test conditions, which are the items or events of a component or system that could be verified by one or more test cases.

In an Agile, iterative, and incremental development model:

III: The performance test may be conducted by a specific team. This is true as dedicated performance testing teams often handle complex performance testing tasks.

IV: A performance test cycle must be performed in each iteration by the development team (Agile). This ensures that performance testing is integrated into each iteration to catch performance issues early.

Statements I and II are not necessarily true:

I: While possible, it is not always the case that there will be a dedicated iteration for performance testing.

II: Performance testing in a cloud-based environment is beneficial but not mandatory.
