CDA Agile Testing & Quality Practices 3

Question 1

In Disciplined Agile, 'behavior-driven development' (BDD) primarily uses which format to express acceptance criteria?

Accepted Answer

Given-When-Then scenarios

Answer

BDD uses Given-When-Then format to express acceptance criteria in plain language that both business stakeholders and developers can understand and automate.

Question 2

A DA team consistently finds bugs in production that were not caught in testing. Which practice would MOST directly address this issue?

Accepted Answer

Implementing risk-based testing to prioritize high-impact areas

Answer

Risk-based testing focuses effort on the areas most likely to fail and most critical to the business, reducing the chance of high-impact bugs reaching production.

Question 3

What does 'continuous testing' mean in a Disciplined Agile context?

Accepted Answer

Automated tests run as an integral part of the CI/CD pipeline after every code commit

Answer

Continuous testing integrates automated tests into the CI/CD pipeline so every commit triggers a test run, providing immediate feedback on code quality.

Question 4

Which metric is MOST useful for a DA team tracking the effectiveness of their test automation suite?

Accepted Answer

Defect escape rate (bugs found in production vs. total bugs found)

Answer

Defect escape rate measures how many defects slip past testing into production, directly reflecting the suite's effectiveness at catching real issues.

Question 5

In the DA toolkit, what is the key difference between 'validation' and 'verification' in testing?

Accepted Answer

Verification ensures we built the product right; validation ensures we built the right product

Answer

Verification confirms the product meets its specifications, while validation confirms the product meets the actual needs and expectations of the customer.
