CAD Continuous Integration and Testing 3

Question 1

What distinguishes Behavior-Driven Development (BDD) from Test-Driven Development (TDD)?

Accepted Answer

BDD uses natural language specifications shared with stakeholders; TDD uses code-level tests written by developers

Answer

BDD extends TDD by expressing tests in human-readable language (e.g., Gherkin) to align developers, testers, and business stakeholders.

Question 2

In contract testing for microservices, what does the 'consumer' define?

Accepted Answer

The expectations about the provider's responses that it relies on

Answer

Consumer-driven contract testing lets each consumer specify exactly what it needs from a provider, enabling independent deployability.

Question 3

What is 'shift-left testing' in Agile development?

Accepted Answer

Moving testing activities earlier in the development lifecycle

Answer

Shift-left means catching defects as early as possible—during design and coding—rather than in late-stage QA phases.

Question 4

Which type of test verifies that independently developed modules work correctly together?

Accepted Answer

Integration test

Answer

Integration tests validate the interactions and data flow between two or more components or services.

Question 5

A CI pipeline runs static code analysis. What is the primary benefit?

Accepted Answer

It catches code quality issues, security vulnerabilities, and style violations automatically before merge

Answer

Static analysis tools scan code without executing it, catching bugs, code smells, and security issues early in the pipeline.
