Question 1

Which statement about test automation is TRUE?

SELECT ONE OPTION



Answer : C

The true statement about test automation, particularly in contexts aiming for continuous deployment, is that increasing automation levels is generally pursued to increase deployment frequency. Automated tests can be executed faster and more frequently than manual tests, thereby supporting rapid iterative development and continuous integration practices. This accelerates the overall software development process, allowing for quicker deployments to production .


Question 2

Your Agile team is developing a web-based system that will allow users to browse and buy online from a store's shopping catalogue. Continuous Integration has been implemented and technically it is working well, running several times per day, but each run is taking almost as much time as the team is prepared to allow. It is clear that after a few more iterations, as the number of tests needed grows with the product, it will be taking too much time.

Which of the four options contains a pair of solutions that will BOTH help to solve this problem?

a. Only include unit and component integration tests in the automated Cl runs.

b. Schedule low priority tests to be the first ones executed in each run, in order to provide rapid build verification.

c. Reduce the extent to which the automated tests go through the user interface, using technical interfaces instead.

d. Reduce the number of Cl cycles run each day.

e. Select a subset of automated tests for the daytime Cl runs, and run as many of the other tests as possible in an overnight cycle.

SELECT ONE OPTION



Answer : C

The correct option for addressing the issue of increasing test run times in a Continuous Integration (CI) environment is option C: reducing the extent to which automated tests go through the user interface, and selecting a subset of automated tests for the daytime CI runs while running many of the other tests in an overnight cycle.

Reducing User Interface Tests: By reducing the extent of tests that go through the user interface (UI) and using technical interfaces instead, you can significantly decrease the time each test takes. UI tests are generally slower due to rendering and user interaction simulations.

Optimizing Test Scheduling: By selecting only a subset of tests for daytime CI runs and scheduling extensive testing for overnight runs, the team can manage the test load better without compromising the frequency of integration, thus ensuring continuous testing does not become a bottleneck.

This dual approach effectively manages both the execution time of individual tests and the overall test process across the development cycle, maintaining the agility of the CI process without sacrificing the breadth of testing necessary for quality assurance .


Question 3

The following characteristics were identified during an early product risk-assessment for a software system:

* the software system needs to manage synchronization between various processes

* microcontrollers will be used that will limit product performance

* the hardware that will be used will make use of timeslots

* the number of tasks supported in parallel by the software system is large and are often highly complex.

Based on the information provided, which of the following non-functional test types is MOST appropriate to be performed?



Answer : C

The characteristics listed in the question point towards the need to manage synchronization between processes and make efficient use of limited hardware resources, such as microcontrollers and timeslots. Additionally, the complexity and concurrency of tasks highlight the importance of the software's performance over time. Time-behaviour testing is the most appropriate non-functional test type to perform in this scenario as it focuses on evaluating the timing aspects of the system, such as response times, processing times, and throughput rates. It ensures that the system meets its time-related requirements, which is critical for systems reliant on synchronization and limited by hardware performance constraints.


Question 4

A new application for planning journeys on public transport is being developed that will work on mobile devices. Why would you MOST likely include Portability testing in the test plan?



Answer : C

Analysis:

Portability testing evaluates the ease with which software can be transferred from one environment to another. For a mobile application, portability testing ensures that the application functions correctly across different devices and operating systems.

Key Aspect:

C . To evaluate the effectiveness and efficiency in which it can be successfully uninstalled in a specified environment:

This is an aspect of portability testing that checks whether the application can be correctly and completely removed from a device, ensuring no residual data or configuration is left behind. This is critical for mobile applications that need to be installed and uninstalled on various devices.

Explanation of Incorrect Options:

A . To evaluate the degree to which it is easy to operate and control:

This pertains to usability rather than portability.

B . To evaluate the degree to which its components can be used in other systems:

This is related to reusability, not portability.

D . To evaluate the degree to which the system is operational and accessible when required for use:

This relates more to reliability and availability, not specifically portability.


The ISTQB CTAL-TTA syllabus and standard practices in portability testing emphasize the importance of installation and uninstallation processes for ensuring software can be effectively managed across different environments.

Question 5

A new application for planning journeys on public transport is being developed that will work on mobile devices. Why would you MOST likely include Compatibility testing in the test plan?



Answer : C

Analysis:

Compatibility testing is essential for applications that are designed to work across various hardware and software environments, particularly for mobile devices which can have diverse specifications and operating systems.

C . To evaluate the degree to which it can effectively and efficiently be adapted for different or evolving hardware environments:

This option addresses the core purpose of compatibility testing for a mobile application. It ensures that the application works as intended across different mobile devices and operating systems, which is crucial for public transport applications that must function reliably on various devices used by the public.

Explanation of Incorrect Options:

A . To evaluate the degree to which it is operational and accessible when required for use:

This is more related to availability and reliability rather than compatibility.

B . To evaluate the degree to which its functions facilitate the accomplishment of specified tasks and objectives:

This pertains to functionality testing, not compatibility.

D . To evaluate the degree to which the system is operational and accessible when required for use:

This duplicates option A and is not directly related to compatibility.


The ISTQB CTAL-TTA syllabus covers compatibility testing and its relevance in ensuring applications function correctly across different environments and hardware configurations.

Question 6

You are part of an agile team creating a user story.

Which of the following requirements engineering techniques would you use to provide a visual representation of the system and help to see the 'overall* story with the functional flow?

SELECT ONE OPTION



Answer : C

Story Mapping is an effective requirements engineering technique used in Agile environments to provide a visual representation of the system. It helps in understanding the 'overall' story and functional flow by mapping user stories along a timeline or process steps, laying them out in a two-dimensional structure that represents the product backlog. This technique is particularly useful for visualizing the scope of large features or entire systems, making it easier to plan releases and improve understanding among the team .


Question 7

At which test level would reliability testing most likely be performed?



Answer : C

Reliability testing is aimed at verifying the software's ability to function under expected conditions for a specified period of time. It is typically conducted during system testing, where the software is tested in its entirety to ensure that all components work together as expected in an environment that closely simulates the production environment. Reliability testing is not typically associated with static testing, component testing, or functional acceptance testing, as these levels of testing do not address the overall behavior of the system over time.
