ISTQB CTAL-TTA Certified Tester Advanced Level Technical Test Analyst Exam Practice Test

Answer : B

Analysis:

When implementing a new performance test tool, it is crucial to consider the capabilities of the tool in relation to the system under test and the operational profiles.

B . The load generation suggested by the operational profiles of the users may exceed the available hardware and network bandwidth of the tool:

This is a key consideration because if the tool cannot generate the required load due to hardware or network limitations, it will not accurately simulate real-world conditions and may lead to invalid test results.

Explanation of Incorrect Options:

A . The lack of flexibility in the tool may mean that it is unable to generate incorrect inputs for all the different types of virtual user:

While flexibility is important, performance testing primarily focuses on load and stress, not on generating incorrect inputs.

C . The model used to describe the intended execution-time behavior of the system under test may not be compatible with the tool:

This is less likely to be a primary consideration compared to the tool's ability to handle the required load.

D . The language used for programming the system under test may be different from that used to develop the tool:

The programming language differences are typically not a critical issue for performance testing tools, as they interact with the system at a higher level.

The ISTQB CTAL-TTA syllabus discusses the considerations for selecting and implementing performance testing tools, highlighting the importance of ensuring the tool can handle the expected load.

Answer : B

Analysis:

Fault injection tools are used to introduce faults into a system to test its robustness and error-handling capabilities.

B . They deliberately introduce incorrect inputs to a system to ensure it can withstand and recover from error conditions:

This statement correctly describes the purpose of fault injection tools, which is to introduce faults or errors to evaluate how well the system can handle and recover from these conditions.

Explanation of Incorrect Options:

A . They modify the code under test in order to check the coverage achieved by specified tests:

This describes code coverage tools, not fault injection tools.

C . They inject defects into the SUT to test the error handling capabilities of test automation software:

Fault injection tools test the system under test (SUT) itself, not the test automation software.

D . They can detect memory leaks and wild pointers when a component is executing:

This describes dynamic analysis tools, not fault injection tools.

The ISTQB CTAL-TTA syllabus covers the use of fault injection tools and their role in testing the robustness of systems.

Answer : A

Analysis:

To determine the correct keyword-driven input table for testing the enhancement to the social media application, we need to ensure the table adequately covers the following scenarios:

Adding existing members to a group.

Attempting to add non-existing members to a group and handling the error.

Removing members from a group.

Deleting groups only if no members are attached.

A . (Image A) - Assuming Image A correctly represents these scenarios.

Adding Members: The table should include steps to add both valid (existing) and invalid (non-existing) members to a group, ensuring the application correctly handles both scenarios.

Removing Members: The table should include steps to remove members from a group.

Deleting Groups: The table should include a scenario where a group with no members is deleted successfully.

The ISTQB CTAL-TTA syllabus and standard keyword-driven testing practices emphasize the importance of comprehensive test coverage for new enhancements.

Answer : B

Analysis:

One of the common technical issues that can lead to the failure of an automation project is the improper management of test environments, particularly the failure to reset the system to a known state after tests are executed.

Key Technical Issue:

B . Not returning the system to a pre-defined state after completing the execution of a suite of automated tests:

Ensuring that the system is reset to a known state after each test run is crucial for maintaining test consistency and reliability. Without this, subsequent tests may produce unreliable results due to residual data or configurations from previous tests.

Explanation of Incorrect Options:

A . Technical Test Analysts not developing business domain expertise for keyword-driven testing:

While domain expertise is beneficial, the lack of it is not a primary technical issue that would cause an automation project to fail.

C . Having to manually plan how to handle software failures in a test automation design:

Manual planning for handling failures is part of test design and does not inherently cause project failure.

D . Automated tests uncovering a higher than expected rate of defects in the software under test:

Finding defects is the purpose of testing and does not represent a failure of the automation project.

The ISTQB CTAL-TTA syllabus and standard practices in test automation emphasize the importance of environment management and maintaining a consistent test state.

Answer : C

Analysis:

Understanding the characteristics of data-driven and keyword-driven automation is crucial for identifying the correct statements.

Correct Pairing:

C . Data Driven = a; Keyword-driven = c:

Data Driven = a: 'The data used for a test is held external to the automated script' is a key characteristic of data-driven testing, where test data is stored separately from the test scripts, allowing the same script to run with different data sets.

Keyword-driven = c: 'It uses a high-level language to separate the action to be performed on the test data from the test script' is characteristic of keyword-driven testing, where keywords representing actions are used to describe test steps, separating the business logic from the test scripts.

Explanation of Incorrect Options:

A . Data Driven = a; Keyword-driven = d: Statement d does not accurately describe keyword-driven testing.

B . Data Driven = b; Keyword-driven = c: Statement b does not accurately describe data-driven testing.

D . Data Driven = d; Keyword-driven = d: Statement d is not accurate for either data-driven or keyword-driven testing.

The ISTQB CTAL-TTA syllabus and standard practices in test automation clearly differentiate between data-driven and keyword-driven testing methodologies.

Answer : D

Analysis:

As a Technical Test Analyst involved in a test automation project, particularly one that uses keyword-driven testing, your responsibilities are primarily technical and related to the creation and management of test data and scripts.

Key Responsibility:

D . Creating and supplying the data to be accessed by keyword-driven automation scripts:

In keyword-driven testing, test data is often stored separately from the test scripts. The Technical Test Analyst is responsible for ensuring that this data is correctly created and managed so that the automation scripts can access and use it effectively.

Explanation of Incorrect Options:

A . Approving the estimated costs for implementing the test automation project:

This is typically a management responsibility rather than a technical task.

B . Determining who will execute the automated tests:

This is more of a project management or team lead responsibility.

C . Defining the business processes that will be used for keyword-driven testing:

While important, defining business processes is more likely to be done by business analysts or process experts rather than a Technical Test Analyst.

The ISTQB CTAL-TTA syllabus outlines the roles and responsibilities of Technical Test Analysts, particularly in the context of test automation projects.

Answer : D

Analysis:

The given pseudo code for solving quadratic equations includes operations that involve division. One of the critical issues in such operations is ensuring that the divisor is not zero, which would result in a division by zero error.

Checklist Item:

D . Are divisors tested for zero or noise?:

This checklist item addresses the potential problem of dividing by zero. In the pseudo code, the variable a is used as a divisor in the formula (-b sqrt(d)) / (2 * a). If a is zero, this will result in a division by zero error. Therefore, it is crucial to test whether a is zero before performing the division.

Explanation of Incorrect Options:

A . Does the code avoid comparing floating point numbers for equality?:

This is important but not directly relevant to the given pseudo code's primary issue.

B . Are all variables properly defined with meaningful, consistent and clear names?:

This is good practice but does not address the critical issue of division by zero.

C . Are there any redundant or unused variables?:

Identifying unused variables is helpful for code clarity but does not address the primary functional issue in the pseudo code.

The ISTQB CTAL-TTA syllabus and standard code review practices emphasize the importance of ensuring safe arithmetic operations, particularly avoiding division by zero.
