technology testing

  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

Show answer
Correct Option: B
Explanation:

To answer this question, the user needs to know what a test case is and its elements. A test case is a set of steps or conditions that are used to test a specific aspect of a software program. It includes a set of inputs, execution preconditions, and expected outcomes.

Now, let's go through each option and explain why it is right or wrong:

A. A test environment description and test instructions: This option is incorrect. While a test case may include test instructions, it is not limited to only that. A test environment description is not an essential element of a test case.

B. A set of inputs, execution preconditions, and expected outcomes: This option is correct. A test case includes a set of inputs, execution preconditions, and expected outcomes. Inputs are the data that is entered into the system as part of the test case, execution preconditions are the conditions that must be met before the test case can be run, and expected outcomes are the results that are expected from the test case.

C. A test plan, test inputs, and logging instructions: This option is incorrect. A test case is a part of a test plan, but it is not the test plan itself. The test inputs are an essential element of a test case, but logging instructions are not necessary.

D. Execution instructions and a function description to determine correct outcome: This option is incorrect. While execution instructions are a part of a test case, they are not the only element. A function description to determine the correct outcome is not a necessary part of a test case.

Therefore, the answer is: B. A set of inputs, execution preconditions, and expected outcomes.

Which of the following provides the test group with the ability to reference all documents and software items unambiguously?

technology testing

  1. Agile testing methodology

  2. Effective use of tools

  3. Configuration management

  4. Requirements traceability matrix

Show answer
Correct Option: C

AI Explanation

To answer this question, you need to understand the concept of configuration management. Let's go through each option to understand why it is correct or incorrect:

Option A) Agile testing methodology - This option is incorrect because Agile testing methodology is a project management and development approach that focuses on iterative and incremental development. While it may provide benefits in terms of collaboration and flexibility, it does not specifically address the ability to reference all documents and software items unambiguously.

Option B) Effective use of tools - This option is incorrect because although the effective use of tools can enhance the testing process, it does not necessarily ensure the ability to reference all documents and software items unambiguously. Tools can help with tasks such as test management, defect tracking, and automation, but they do not provide a systematic approach for unambiguous referencing.

Option C) Configuration management - This option is correct because configuration management is a discipline that focuses on identifying, organizing, and controlling the configuration items (such as documents, software, hardware, etc.) throughout their lifecycle. It provides a systematic approach to managing changes, version control, and ensuring the integrity and traceability of configuration items. By implementing configuration management practices, the test group can ensure that all documents and software items are referenced unambiguously.

Option D) Requirements traceability matrix - This option is incorrect because a requirements traceability matrix is a tool used to trace requirements throughout the development and testing process. While it can facilitate traceability and help ensure that requirements are met, it does not provide the ability to reference all documents and software items unambiguously.

The correct answer is C) Configuration management. This option is correct because configuration management provides the test group with the ability to reference all documents and software items unambiguously by implementing systematic practices for managing changes, version control, and traceability.

Which of the following statements are TRUE for informal reviews? I. Easy to get started and have some benefit II. Have no or minimal formal process III. The process must be documented IV. May include “paired programming”

technology testing

  1. I, II and IV

  2. I and III

  3. III and IV

  4. I, III and IV

Show answer
Correct Option: A

AI Explanation

To answer this question, let's go through each statement and determine if it is true or false for informal reviews:

I. Easy to get started and have some benefit - This statement is true. Informal reviews are generally easier to initiate compared to formal reviews, and they can provide some benefits even without following a strict formal process.

II. Have no or minimal formal process - This statement is true. Informal reviews do not have a structured or formalized process like formal reviews. They are typically more flexible and less rigid in their approach.

III. The process must be documented - This statement is false. Informal reviews do not require a formal documentation process. They are often more casual and less structured, allowing for a more flexible and informal exchange of ideas.

IV. May include "paired programming" - This statement is true. Informal reviews can include activities like paired programming, where two individuals work together to review and improve code or other artifacts.

Based on the above analysis, the correct statements for informal reviews are:

A. I, II, and IV

Therefore, the correct answer is A.

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

technology 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

Show answer
Correct Option: B
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

Which of the following is a TRUE statement about the use of static analysis tools?

technology testing

  1. Static analysis tools can change the code to reduce complexity.

  2. Static analysis tools are intended to support developers only
