Software Architecture, Testing, and Black Box

What’s the primary purpose of software architecture?

To describe the high-level structure of a system

Which of the following is a common software architectural pattern?

MVC (Model-View-Controller)

In the layered architecture, each layer typically:

Communicates only with the layer directly below it

Which quality attribute is most associated with good software architecture?

Scalability

Which of the following best describes modularity in software architecture?

Dividing a system into separate components/modules

What is the main goal of software testing?

To find defects in the software

Which testing level checks individual components or functions?

Unit Testing

Which type of testing verifies the interaction between modules?

Integration Testing

Regression testing is performed to:

Ensure new changes do not break existing functionality

Which of the following is NOT a testing level?

Compilation Testing

Black Box Testing focuses on:

Program input and output behavior

In Black Box Testing, the tester:

Tests based on system specifications only

Which technique is commonly used in Black Box Testing?

Equivalence Partitioning

Boundary Value Analysis is used to:

Test extreme input values

Example: A program accepts numbers 1–100. Which input is best for boundary testing?

1, 100, 0, 101

A tester checks if a login system accepts valid username/password combinations without looking at the code. This is:

Black Box Testing

A developer tests a single function that calculates a student's GPA. This is:

Unit Testing

A software team divides a system into presentation layer, business logic layer, and data layer. This is an example of:

Layered Architecture

Which testing technique divides input data into valid and invalid groups?

Equivalence Partitioning

Testing the complete application to verify that it meets requirements is called:

System Testing
