A system sets new users' password to a temporary password

The temporary password is a random number based on the first sft: characters of the username.

If the username is shorter than 6 characters, the system displays an error message.

Which of the following is a possible representation of equivalence classes for the username string?

{Random number} {Error message}
{Random number} {Error message}
{Error message displayed} {Error message not displayed}
{Error message displayed} {Error message not displayed}
{Username shorter than 6 characters} {Username equal to or longer than 6 characters}
{Username shorter than 6 characters} {Username equal to or longer than 6 characters}
{Username with a permanent password} {Username with a temporary password}
{Username with a permanent password} {Username with a temporary password}
Suggested answer: C

Explanation:

The equivalence classes for the username string are based on the length of the string, not on the type of password or the error message. Therefore, option C is correct, as it divides the username string into two equivalence classes: shorter than 6 characters and equal to or longer than 6 characters. Option A is incorrect, as it does not consider the length of the username string. Option B is incorrect, as it does not specify the criteria for displaying or not displaying the error message. Option D is incorrect, as it confuses the username string with the password string.

A detailed description of a test case to enable its execution by non-expert tester.
A test environment comprised of stubs and drivers needed to execute a test.
A test environment comprised of stubs and drivers needed to execute a test.
Suggested answer: D

Explanation:

A test harness is a test environment comprised of stubs and drivers needed to execute a test, especially when testing components or interfaces. Therefore, option D is correct. Option A is incorrect, as a test harness is not a topic for the final Test Report. Option B is incorrect, as a test harness is not a general name for test data. Option C is incorrect, as a test harness is not a detailed description of a test case.

Which of the following statements correctly describe Black-Box Testing''

Test on an individual software component in isolation from other components, to avoid external influence
Test on an individual software component in isolation from other components, to avoid external influence
Tests that investigate the input vs. trfe output behavior of a software system.
Tests that investigate the input vs. trfe output behavior of a software system.
Test derived from the ability of the testers and their intuition and experience with similar applications and technologies (sometimes used to strengthen systematic techniques)
Test derived from the ability of the testers and their intuition and experience with similar applications and technologies (sometimes used to strengthen systematic techniques)
Test of the interfaces between components and of the interactions with different parts of a system
Test of the interfaces between components and of the interactions with different parts of a system
Suggested answer: B

Explanation:

Black-box testing is a test technique that investigates the input vs. output behavior of a software system, without considering its internal structure or implementation. Therefore, option B is correct. Option A is incorrect, as it describes white-box testing, which focuses on the internal structure or implementation of a software system. Option C is incorrect, as it describes exploratory testing, which relies on the testers' intuition and experience. Option D is incorrect, as it describes integration testing, which tests the interfaces and interactions between components or systems.

Which of the following are correct tasks during 'Test analysis and design'?

I, Designing and prioritizing test cases

II, Identifying any required infrastructure and tools

II,I, Reviewing the test basis

IV Creating test data and preparing test harnesses

V, Writing automated test scripts

II, II,I, IV, V
II, II,I, IV, V
l, II,I IV

Suggested answer: C

Explanation:

Test analysis and design is the phase of the test process where test cases and test data are designed and prioritized, based on the test basis and test objectives. Therefore, option C is correct, as it includes tasks I, II, and II,I, Option A is incorrect, as it includes tasks IV and V, which are part of test implementation and execution phase. Option B is incorrect, as it includes task IV, which is part of test implementation and execution phase. Option D is incorrect, as it does not include task II,I, which is part of test analysis and design phase.

Which of the following should be considered when purchasing a test execution tool?

The ability of the tool to trace tests to requirements and report coverage level
The ability of the tool to trace tests to requirements and report coverage level
The amount of effort required to achieve positive Return on Investment (ROI)
The amount of effort required to achieve positive Return on Investment (ROI)
The ability of the tool to track the output and productivity of each individual tester
The ability of the tool to track the output and productivity of each individual tester
The ability of the tool to run the unit-level tests for the developers
The ability of the tool to run the unit-level tests for the developers
Suggested answer: D

Explanation:

A test execution tool is a tool that executes tests on a software system and logs the outcomes of each test step. The ability of the tool to run the unit-level tests for the developers is one of the factors that should be considered when purchasing a test execution tool, as it can improve the efficiency and effectiveness of testing at this level. The other options are not relevant to test execution tools, but to other types of tools such as test management tools, test measurement tools, and requirements management tools.

Requirements for documentation
Requirements for documentation
Quality of the test basis Work
Quality of the test basis Work
Breakdown Structure
Breakdown Structure
Skills of the test team
Skills of the test team
Suggested answer: C

Explanation:

Work Breakdown Structure (WBS) is a project management technique that decomposes a project into smaller and manageable tasks. It is not a factor that is used as a basis for estimating testing effort, but rather an outcome of the estimation process. The other options are factors that can influence the testing effort, such as the quality of the test basis, the requirements for documentation, and the skills of the test team.

No The cost of testing cannot be measured effectively, so it is incorrect to use cost as an exit criteria
No The cost of testing cannot be measured effectively, so it is incorrect to use cost as an exit criteria
Suggested answer: B

Explanation:

Cost can be regarded as an exit criterion, as it is one of the factors that can influence the decision to stop testing. Spending too much money on testing will result in an unprofitable product, and having cost as an exit criterion helps avoid this. The other options are incorrect, as the financial value of product quality can be estimated, the cost of testing can be measured effectively, and having cost as an exit criterion does not necessarily constrain the testing project or help achieve the desired quality level.
