CDA Agile Testing & Quality Practices 2

Question 1

In Disciplined Agile, what does the practice of 'test-driven development' (TDD) primarily aim to achieve?

Accepted Answer

Drive design through small, failing tests written before production code

Answer

TDD drives design by writing a failing test first, then writing minimal code to pass it, resulting in cleaner, more testable design.

Question 2

Which Agile testing quadrant focuses on technology-facing tests that critique the product, such as performance and security testing?

Accepted Answer

Quadrant 4

Answer

Agile Testing Quadrant 4 covers technology-facing tests that critique the product, including performance, load, security, and 'ility' testing.

Question 3

A DA team discovers that their automated test suite takes 45 minutes to run. What is the BEST approach according to Agile quality practices?

Accepted Answer

Parallelize tests and optimize to keep the suite under 10 minutes

Answer

Fast feedback is essential in Agile; teams should optimize and parallelize test suites so developers get results quickly, ideally within 10 minutes.

Question 4

What is 'exploratory testing' in the context of Disciplined Agile?

Accepted Answer

Unscripted, simultaneous learning, test design, and execution guided by tester judgment

Answer

Exploratory testing is a simultaneous process of learning, designing, and executing tests, driven by the tester's skill and curiosity rather than predefined scripts.

Question 5

In DA, which quality practice involves team members other than the author reviewing code changes before they are merged?

Accepted Answer

Code review / pull request review

Answer

Code reviews (often via pull requests) involve peers examining code changes for defects, style issues, and design concerns before merging.
