When specifying a software requirement, it is essential to consider how the requirement might be

validated. Validation ensures that the software meets the needs and requirements of the

stakeholders and functions as intended in the real-world environment. Without proper validation

criteria, it would be challenging to confirm whether the software fulfills its intended purpose.

A test plan should be changed after changes to the design specifications. This ensures that the tests

remain relevant and accurately reflect the new design and functionality of the software. Keeping the

test plan updated with design changes helps ensure comprehensive test coverage and alignment

with the project's requirements.

Reference: IEEE 829-2008 (IEEE Standard for Software and System Test Documentation), which

outlines the importance of maintaining an up-to-date test plan to reflect changes in design and

requirements.

Concurrently developing software, where multiple developers work on different parts of the

codebase simultaneously, requires more rigid version control. This is because:

Managing Changes: Ensuring that changes made by one developer do not conflict with changes

made by another.

Maintaining History: Keeping a detailed record of modifications to understand the evolution of the

codebase and to revert changes if necessary.

Robust version control systems (VCS) like Git facilitate concurrent development by managing

branches, merges, and conflict resolution effectively.

Test data requirements describe the specific data needed to execute test cases effectively. This

includes defining the characteristics and properties of data items, such as format, type, and values.

Properly describing test data ensures that tests can be executed accurately and consistently, which is

crucial for validating software functionality and performance.

A walk-through is a type of peer review where the author of a document or code presents their work

to a group for feedback.

Presenter Role:

Developer: The person who created the document or code typically presents it.

Objective: To explain their thought process and receive feedback on potential improvements or

defects.

Nature of Walk-Throughs:

Informal: Less formal than inspections, aiming to get early feedback.

Participation: Encourages participation from peers to improve the quality of the work.

Reference: Common practices in software development highlight that the author or developer is the

presenter in walk-through sessions to ensure accurate representation and understanding of the work

being reviewed.

Integration testing is a type of testing conducted to evaluate the interfaces and interactions between

different modules of source code. Here’s why integration testing is the correct choice:

Definition: Integration testing focuses on verifying that the modules or components of an application

work together as expected. It checks for data flow between modules and ensures that integrated

units function correctly.

Scope: Unlike system testing (which tests the entire system) or component testing (which tests

individual components), integration testing specifically targets the interactions and interfaces

between modules.

Purpose: The goal is to identify issues that arise when combining components, such as incorrect data

exchange, communication errors, and interface mismatches.

Reference: "Software Testing Techniques: Integration testing is crucial for ensuring that different

parts of an application work together correctly, focusing on the interfaces and interactions between

modules." (IEEE Software Testing Standards)

A Pareto chart should be used to identify the steps in the development process that are the source of

the most software defects. The Pareto chart is a bar graph that identifies the most significant factors

in a dataset and is based on the Pareto principle (80/20 rule), which suggests that 80% of problems

are often due to 20% of the causes. This tool helps in pinpointing the primary sources of defects so

that improvement efforts can be focused effectively.

In agile development, changes to requirements are a common and expected part of the process. The

product backlog, which is a prioritized list of tasks and requirements for the project, is the main tool

for managing these changes.

Requirement Identification: New requirements or changes are identified during various stages of the

development process, often during interactions with stakeholders or as the team gains a deeper

understanding of the project.

Product Backlog: These new requirements are then added to the product backlog. The product

backlog is managed by the product owner, who is responsible for maintaining its order of priority

based on the project's goals and stakeholder feedback.

Prioritization: The product owner prioritizes the backlog items to ensure that the most valuable and

important features are addressed first. This prioritization helps in managing scope and delivering

value incrementally.

Sprint Planning: During sprint planning, the team selects items from the top of the product backlog

to include in the next sprint, based on their capacity and the priority set by the product owner.

In software testing, a driver is a piece of code that replaces a higher-level module to test a lower-

level module by establishing a function and passing test data to that function. Drivers are used in

bottom-up integration testing to simulate the behavior of higher-level modules that have not yet

been developed or integrated.
