Multiple choice technology testing

Which of the following are good candidates for manual static testing?

  1. Requirement specifications, test plan, code, memory leaks

  2. Requirement specifications, test cases, user guides.

  3. Requirement specifications, user guides, performance

  4. Requirement specifications, website, code, use cases
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

To answer this question, the user needs to understand the concept of static testing. Static testing is a form of software testing that involves reviewing documentation or code without executing the actual program. It is done manually and aims to find defects early in the development process.

Option A includes code and memory leaks, which are not good candidates for manual static testing. Code is typically tested through dynamic testing, while detecting memory leaks requires the use of specialized tools.

Option B is a good candidate for manual static testing. Requirement specifications, test cases, and user guides can all be reviewed manually to identify defects and improve the quality of the software.

Option C includes performance, which is not well-suited for manual static testing. Performance testing is typically done dynamically and requires the use of specialized tools to measure and analyze the software's behavior under different conditions.

Option D includes a website, which is not a good candidate for manual static testing. Websites are typically tested through dynamic testing, using specialized tools to simulate user interactions and test the website's functionality.

Therefore, the correct answer is:

The Answer is: B

Multiple choice technology testing

How does testing contribute to software quality?

  1. Testing ensures that the system under test will not error out in a production environment

  2. Testing identifies defects which ensures a successful product will be released to market

  3. Testing increases the quality of a software system by avoiding defects in the system under test.

  4. Testing through verification and validation of functionality identifies defects in the system under test.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Testing contributes to quality by identifying defects through verification (checking we built it right) and validation (checking we built the right thing). Options A, B, and C overstate testing's capabilities - testing cannot guarantee zero production errors or ensure market success, and it cannot avoid defects (it only finds them).

Multiple choice technology testing

Which of the statements about reviews are correct? I. Reviews are useful because, through their use, defects can be found early, resulting in cost savings. II. Reviews are useful because they help management understand the comparative skills of different developers. III. Testers should not get involved in specification reviews because it can bias them unfavorably. IV. Many early defects are found in reviews, lengthening the time needed for the development life cycle

  1. I

  2. IV

  3. I and IV

  4. I and III
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Statement I is correct: reviews find defects early, which is cost-effective. Statement II is incorrect - reviews are not designed for management to compare developer skills. Statement III is incorrect - testers SHOULD participate in specification reviews to provide early input. Statement IV is incorrect - reviews actually SHORTEN the lifecycle by catching defects before expensive rework.

Multiple choice technology testing

What is integration testing?

  1. Integration of automated software test suites with the application under test.

  2. Testing performed to expose faults in the interaction between components and systems.

  3. Testing to verify that a component is ready for integration with the rest of the system.

  4. Testing to verify that the test environment can be integrated with the product
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Integration testing is designed to detect defects in the interfaces and interactions between integrated components or systems. The distractors are incorrect as they refer to test suite automation integration, individual component readiness validation, or test environment configuration rather than interactive testing.

Multiple choice technology testing

A test case has which of the following elements?

  1. A test environment description and test instructions.

  2. A set of inputs, execution preconditions, and expected outcomes

  3. A test plan, test inputs, and logging instructions.

  4. Execution instructions and a function description to determine correct outcome.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is a duplicate of question 158656. A test case is formally defined as a set of inputs, execution preconditions, and expected outcomes. Option B is the only complete, accurate definition. Options A, C, and D either omit essential elements or include elements not part of the standard test case definition.

Multiple choice technology testing

Which of the following statements is TRUE?

  1. Component integration testing tests the interactions between different systems and is done after

  2. Component integration testing tests the interactions between different systems and may be done after

  3. Component integration testing tests the interactions between software components and is done during

  4. Component integration testing tests the interactions between software components and is done after
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Component integration testing evaluates the interfaces and interactions between software components and is executed after component testing has been completed. The distractor options incorrectly refer to interactions between different systems, which describes system integration testing rather than component-level integration.

Multiple choice technology testing

What is non-functional testing?

  1. Testing an integrated system to verify that it meets specified requirements

  2. Testing the internal structure of the system to ensure it’s built correctly

  3. Testing the way the system works without regard to the level of test

  4. Testing characteristics such as usability or reliability
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Non-functional testing verifies quality characteristics - how the system behaves rather than what it does. This includes attributes like usability, reliability, performance, security, and efficiency. Functional testing checks whether the system meets specified functional requirements (what features work), while non-functional testing evaluates the quality of those features (how well they work).

Multiple choice technology testing

Which activities are included in the Test Analysis and Design phase?

  1. Design of test cases that verify that user functions are correct.

  2. The design of test cases for testing the internal structure of the system.

  3. Test case design that is based on an analysis of the behavior of the component without reference to its

  4. The design of test cases to ensure that the organization has defined exactly what the customer wants.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Test Analysis and Design includes creating test cases based on black-box techniques that analyze component behavior without examining internal structure. Options A and B describe functional (specification-based) and structural (white-box) testing respectively, which are specific techniques. Option D suggests gathering requirements, which happens in earlier phases. The Test Analysis and Design phase creates test specifications through both black-box and white-box approaches.

  4. Incident Managers
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To solve this question, the user needs to know about the software development process and the roles of different team members involved in the process.

Debugging is a process of identifying and fixing errors or bugs in software code. It is an essential part of the software development process and is usually performed by developers who write the code.

Option A: Developers- This option is correct. Debugging is a task that developers usually perform. They are responsible for writing the code and testing it for errors. When an issue is identified, they need to debug the code to fix the problem.

Option B: Analysts- This option is incorrect. Analysts are responsible for understanding business requirements, creating functional specifications, and validating that the software meets the requirements. They are not directly involved in debugging activities.

Option C: Testers- This option is incorrect. Testers are responsible for verifying that the software meets the requirements and performs as expected. They are not responsible for identifying and fixing errors in the code.

Option D: Incident Managers- This option is incorrect. Incident managers are responsible for managing and resolving incidents that occur during the software development lifecycle. They are not responsible for identifying and fixing errors in the code.

The Answer is: A
