Question 1

Which of the following is a reason for the Technical Test Analyst to take the time to prepare for a code review?

AAllows the reviewer time to consider the Interaction of the item being reviewed with other items In the system

BAllows time to prepare the test data

CAllows time to gather the test metrics for management review

DAllows time to plan the design and implementation of the item being reviewed

Answer : A

Preparing for a code review is essential for understanding how the specific item under review interacts with other system components. This preparation allows the reviewer to identify potential integration issues or dependencies that could affect system functionality or performance. Adequate preparation ensures that the review is thorough and considers the broader system context, which is critical for ensuring that the system operates cohesively and according to specifications.

Question 2

You are working on a complex systems integration project that will soon be deployed to the production environment. This system is replacing a system that was popular with the users and had no outstanding non-functional issues. There are multiple components that interact and these have been developed by various development and testing groups including some outsourced groups. You will be leading the performance testing effort. Although you would prefer to have a dedicated test system for this effort, you will have to use the production system. You can do this testing at a low usage time, but there will be some users on the system and you will be using real data for the tests. You are now planning your performance testing. Unfortunately, there are no requirements for the performance requirements of the system. How do you determine the acceptable performance levels for the various operational profiles?

AYou should check the performance of the legacy system and use that as a benchmark for the new system

BYou should ask the users what they expect to see for the performance

CYou should go back to the business analysts and require them to update the requirements to include the performance expectations

DYou should use industry standard performance benchmarks

Answer : A

Given the absence of defined performance requirements for the new system, a practical approach is to use the performance metrics of the legacy system as a benchmark. This method is beneficial as it provides a clear, historical baseline of what users are accustomed to and accept as satisfactory performance. Benchmarking against the legacy system ensures the new system meets or exceeds the performance levels that users already find acceptable, which can facilitate smoother acceptance and transition to the new system.

Question 3

Which of the following is a true statement regarding a continuous integration environment?

ABuilds are done regularly every night

BAutomation tools are used to verify the results of the build

CUnit testing is performed manually by the developers prior to code check in

DPerformance efficiency testing is conducted for every accepted build

Answer : B

In a continuous integration environment, it's true that automation tools are used to verify the results of the build. This practice ensures that as new code integrations occur, they do not disrupt existing functionality and that all tests pass successfully before further deployments.

Question 4

You are responsible for planning the non-functional testing for a new product. You will be responsible for the performance testing and you have determined that you will need a simulator to complete your work, Which of the following are considerations when purchasing a simulator?

1. Path testing of the tool

2. Time to test the tool

3. cost of hmng specialists

4. Susceptibility to the "probe effect"

5. Method and bme to upgrade and retest the tool as the software changes

6. Control flow analysis

A1,4,6

B2, 3, 5

C4, 5,6

D1,2, 3, 4, 6

Answer : B

When purchasing a simulator for performance testing, considerations should include:

Time to test the tool -- How long it will take to validate the simulator itself.

Cost of hiring specialists -- The financial aspect of requiring specialized knowledge to operate or customize the simulator.

Method and time to upgrade and retest the tool as the software changes -- How the simulator can be kept up-to-date with the software it is meant to simulate and the effort involved in retesting it after updates.

These points focus on practical and economic aspects of using a simulator in testing environments.

Question 5

Consider the following pseudocode segment:

set a = 1

while a < 12

display ''this is loop", a

if a > 10 then

display "loop is > 10'

set a = 5

else

display ''loop is < 11*

endif

end while

display ''Final value of a is", a

Which of the following issues should be detected in the code review?

ALoop termination is not achievable

BRounding errors on the loop counters could cause problems

CVariables are used before they are initialized

DSome of the code could be moved to re-usable functions

Answer : A

The pseudocode provided includes a while loop that adjusts the loop variable a within the loop's conditional code block. This adjustment, set a = 5, occurs when a > 10. Because the loop checks a < 12 as its continuation condition, and a is reset to 5 repeatedly once it exceeds 10, the loop will execute indefinitely, preventing termination. This creates an infinite loop situation since the condition a < 12 will perpetually remain true once a exceeds 10. This is a critical logic error needing correction for proper execution flow.

Question 6

In what circumstances should you use a simulator instead of an emulator when testing a mobile application?

AWhen a model of the runtime environment Is sufficient for testing

BWhen security is not a consideration

CWhen the hardware device and the runtime environment must be modeled

DWhen there is a need to assess the usability of the application

Answer : A

Simulators and emulators are tools used for testing mobile applications under different conditions. A simulator mimics the software environment but does not emulate hardware. Thus, it is suitable when the test objectives are focused on the application's internal behavior within the context of the software environment, not requiring an exact replica of the hardware conditions. This makes simulators particularly useful for scenarios where the primary concern is how the application runs in the software environment, rather than how it interacts with the underlying hardware.

Question 7

Which of the following best describes the reason why poorly written code is usually more difficult to maintain than well written code?

AIt tends to run more slowly, causing performance issues that may be difficult to fix

BIt tends to contain security issues that may require maintenance releases

CIt tends to be difficult for a developer to locate and accurately fix a problem

DIt tends to have a lot of internal documentation

Answer : C

Poorly written code often lacks clarity, consistency, and may not follow best practices, making it harder to understand and maintain. When code is not well-structured or logically organized, identifying the source of bugs or understanding how changes might affect system behavior becomes more difficult. This issue is compounded when developers other than the original author need to work on the code, as they may struggle to interpret the intended functionality and interdependencies without clear, readable code.
