Consider the following section of pseudocode
Display "You exceeded the number of tries to enter a password. Your account is now locked. Call customer.
For this section of code, which of the following issues should be identified during a code review?
1. Variables have not been properly defined with meaningful names
2. There are unused variables defined
3. Divisors are not tested for zero
4. Loop counters are not properly initialized
5. There are endless loops
6. There are statements within the loop that should be outside the loop
- A. 1, 3, 4, 5
- B. 2, 3, 5, 6
- C. 7, 3, 4, 6
- D. 1, 2, 4, 6
正解：D
解説：
The pseudocode provided for review indicates a password entry system with a lockout mechanism after a certain number of failed attempts. The issues identified during the code review are:
* Variables have not been properly defined with meaningful names - the variables used in the pseudocode are not descriptive, which can make the code difficult to understand and maintain.
* There are unused variables defined - the pseudocode includes variables that are declared but not used, which is inefficient and can lead to confusion.
* Loop counters are not properly initialized - if a loop counter is used, it must be initialized correctly to ensure the loop functions as intended.
* There are statements within the loop that should be outside the loop - certain messages or actions may be repeated unnecessarily within a loop when they should be placed outside to execute only once.
References = ISTQB Advanced Level Agile Technical Tester documents and study resources emphasize the importance of clear, maintainable code, which includes using meaningful variable names, removing unused variables, proper initialization of loop counters, and correct placement of code statements to avoid redundancy and inefficiency in code execution. These principles are essential for agile technical testing to ensure that the code remains robust and adaptable to changes.

質問 # 22
You are testing a payment processing application that calls an external service at a bank to process the monetary transactions. The bank charges per transaction for the use of their service. You are creating an automation suite that will be used as part of continuous testing. How could service virtualization benefit the project if a virtualized service is created that will act in the same way as the bank application?
- A. The virtualized service will reduce the cost of testing as there will be no transaction fees charged by the bank to use their test service
- B. The virtualized service will be more secure than the bank transaction, reducing the need to security test the automation code.
- C. The virtualized service will reduce the need for data management
- D. The virtualized service will be faster and that will make the automation suite run faster
正解：A
解説：
Service virtualization can be highly beneficial in a continuous testing environment, especially when dealing with external services that incur costs per transaction. By creating a virtualized service that mimics the behavior of the bank's application, the project can avoid the transaction fees that would otherwise be charged for each test execution. This not only reduces the cost of testing but also allows for more frequent and comprehensive testing without the concern of incurring high expenses.
References = The ISTQB Advanced Level Agile Technical Tester syllabus outlines the importance of understanding service virtualization concepts as part of supporting test automation activities in an Agile project12. It is a key technique to ensure tests provide adequate coverage without the additional costs associated with using real services1.

Which statement correctly describes service virtualization''
SELECT ONE OPTION
- A. It is a shareable testing service that simulates the behavior, data and performance of a system or service to which the product or component under test would normally be connected
- B. it is a collection of mock objects such as stubs and drivers that will allow a product or component to run without some other product or component that it would normally need
- C. It is a service which automatically deploys new versions of the software into the production environment at regular and short intervals
- D. it is an integrated set of tools that will automatically compile, test and deliver into a virtual environment a new build of the product under test
正解：A
解説：
Service virtualization is a technique used in software testing where a virtualized service simulates the behavior of dependent components that are not available for testing. This allows testing to proceed without waiting for the actual components to be available or operational. It is particularly useful in Agile and continuous testing environments where components may be developed in parallel or where integration points may not yet be stable. Service virtualization helps to create a more controlled and deterministic testing environment, enabling more thorough testing of the product under development.
References = The ISTQB Advanced Level Agile Technical Tester syllabus includes service virtualization as one of the key concepts to understand in the context of Agile testing123.
質問 # 31
which statement about test automation is TRUE7
SELECT ONE OPTION
- A. Test automation will increase the intervals at which continuous deployment to production can be achieved
- B. Test automation levels can be influenced by and can constrain the frequency of code deployments
- C. When continuous deployment is fully implemented it will be necessary to automate only unit and integration tests
- D. When continuous deployment is fully implemented there will be no need for manual testing
正解：B
解説：
Test automation is a key component in Agile development, particularly in the context of continuous deployment and delivery. The level of test automation can indeed influence and potentially constrain the frequency of code deployments. This is because the extent and robustness of automated tests determine how quickly and reliably new code can be pushed to production. If the test automation is not comprehensive or reliable, it may require additional manual testing or cause delays in deployment. Conversely, a high level of test automation can support more frequent and confident deployments by ensuring that new changes do not break existing functionality.
References = The ISTQB Advanced Level Agile Technical Tester syllabus discusses the importance of test automation in Agile projects, including its impact on continuous deployment and delivery12.
