ISTQB Certified Tester Advanced Level Technical Test Analyst Sample Questions (Q86-Q91):
NEW QUESTION # 86
Your team is now accountable for the support and enhancement of a payroll system that has been in production for many years and modified by many different developers. It has been noticed by management that small functional enhancements take much longer than equivalent changes on more recently developed systems. You have been tasked with implementing improved testing approaches that will help to identify the root cause of this problem.
Which of the following is the best technique to apply in this scenario?
- A. Data flow analysis
- B. Static analysis
- C. Exploratory analysis
- D. Orthogonal arrays
Answer: B
Explanation:
Static analysis is the best technique for identifying the root causes of issues in a legacy system where small functional enhancements take disproportionately long to implement. This technique involves examining the code without executing it to detect potential vulnerabilities, coding errors, and complexities. Static analysis can highlight problematic code segments and inefficient coding practices that may contribute to the increased time required for implementing changes, thereby assisting in addressing these systemic issues efficiently.
NEW QUESTION # 87
You are defining the test approach for an Agile project release focused on significantly overhauling the user interface of a golf club's booking system. Additional features will allow more flexible bookings across three courses. These changes are driven by numerous customer complaints about the current system's confusing design and limited options. The release will consist of six two-week sprints.
Stakeholders have performed a risk assessment and consider the impact of system failure as high due to potential customer loss. A regression-averse strategy is recommended due to the extensive changes expected in screen design and functionality.
Which option below represents the BEST test approach for this release? Please use the following symbols consistently:
* + (highly recommended)
* (recommended)
* o (neutral/optional)
* * (not recommended)
* - (not to be used)
SELECT ONE OPTION
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
In addressing the scenario described in the question, the primary considerations for choosing a test approach include the focus on overhauling the user interface, adding new features, and addressing customer complaints in a high-risk environment due to potential customer loss. A regression-averse strategy is also highlighted as critical due to significant changes in design and functionality.
Option D (2) is marked with + for Exploratory Testing (manual) and for Black-box Testing, with Test Automation marked as not to be used (). This selection aligns best with the project's needs for several reasons:
* Exploratory Testing (Highly Recommended): This type of testing is crucial in Agile projects, especially when dealing with UI changes and new functionalities. Exploratory testing allows testers to interact with the system in ways that typical scripted testing may not cover, making it ideal for catching unforeseen issues in new interfaces and features.
* Black-box Testing (Recommended): This testing focuses on the functionality of the application without needing to understand the internal workings. Given the UI overhaul and feature additions, ensuring that the system behaves as expected from an end-user's perspective is necessary.
* Avoidance of Test Automation (Not to be Used): While automation is valuable, focusing primarily on manual testing techniques like exploratory testing is suggested for this specific release due to the extensive UI changes and the need for creative and intuitive testing approaches that adapt quickly to newly developed features.
By using Option D, the test approach supports the dynamic and user-focused nature of the release, addressing both the technical aspects of functionality and the user experience enhancements that are central to this overhaul .
NEW QUESTION # 88
Consider the pseudo code provided below:
Given the following tests, what additional test(s) (if any) would be needed in order to achieve 100% statement coverage, with the minimum number of tests?
Test 1: A = 7, B = 7, Expected output: 7
Test 2: A = 7, B = 5, Expected output: 5
- A. A=6, B=12, Expected output: Bingo! and A=7, B=9, Expected output: 7
- B. No additional test cases are needed to achieve 100% statement coverage.
- C. A=7, B=9, Expected output: 7
- D. A=6, B=12, Expected output: Bingo!
Answer: B
Explanation:
100% statement coverage means that every line of code is executed at least once during testing. Based on the provided pseudo-code and the test cases given:
* Test 1 executes the MIN = B statement when A and B are equal.
* Test 2 executes the MIN = A statement and skips the inner IF since B is not equal to 2*A.
All statements within the code have been executed by these two tests, hence no additional test cases are needed to achieve 100% statement coverage.
