CAD CAD Test-Driven Development and Agile Testing

Question 1

In Test-Driven Development (TDD), what is the correct order of the development cycle?

Accepted Answer

Write test, write code, refactor

Answer

TDD follows the Red-Green-Refactor cycle: write a failing test first, then write just enough code to pass it, then refactor.

Question 2

What does a 'red' phase in TDD indicate?

Accepted Answer

A newly written test is failing because the feature doesn't exist yet

Answer

In TDD, 'red' means the test was just written and fails because the production code implementing that behavior has not yet been created.

Question 3

Which type of test validates interactions between multiple integrated components in an Agile project?

Accepted Answer

Integration test

Answer

Integration tests verify that multiple components or services work correctly together, catching interface and contract issues between units.

Question 4

What is the primary goal of Acceptance Test-Driven Development (ATDD)?

Accepted Answer

To define acceptance criteria as executable tests before development begins

Answer

ATDD involves the whole team — developers, testers, and business stakeholders — collaboratively writing acceptance tests before coding starts to clarify requirements.

Question 5

In Agile, what is 'exploratory testing'?

Accepted Answer

Simultaneously designing and executing tests based on tester intuition and learning

Answer

Exploratory testing is a simultaneous learning, test design, and execution approach where the tester adapts their strategy based on findings during the session.
