Behavior-driven development (BDD) concept in Testing Fundamentals - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Behavior-driven Development (BDD)?

BDD is a software development approach that encourages collaboration between developers, testers, and business people by writing tests in simple language that describes the behavior of the application.

beginner

What format is commonly used to write BDD scenarios?

BDD scenarios are often written in Gherkin language using Given-When-Then steps to describe the context, action, and expected outcome.

Why is collaboration important in BDD?

Collaboration ensures everyone understands the requirements clearly and agrees on the expected behavior, reducing misunderstandings and bugs.

How does BDD improve test automation?

BDD uses human-readable scenarios that can be automated as tests, making it easier to maintain and understand automated test suites.

beginner

Give an example of a simple BDD scenario.

Example: Given the user is logged in When the user clicks the logout button Then the user should be logged out and see the login page.

What does the 'Given' step in a BDD scenario describe?

A The initial context or state before an action

B The action the user takes

C The expected result after the action

D The code implementation details

'Given' sets up the starting point or context for the scenario.

Which language is commonly used to write BDD scenarios?

A SQL

B Python

C JavaScript

D Gherkin

Gherkin is a simple language used to write BDD scenarios in a readable format.

Who should be involved in writing BDD scenarios?

A Only developers

B Developers, testers, and business stakeholders

C Only testers

D Only project managers

BDD encourages collaboration among developers, testers, and business people.

What is the main benefit of BDD?

A Clear understanding of application behavior

B Faster coding

C Less documentation

D More complex tests

BDD helps everyone understand how the application should behave.

In BDD, what does the 'Then' step represent?

A The initial setup

B The user action

C The expected outcome or result

D The test code

'Then' describes what should happen after the action.

Explain the main idea behind Behavior-driven Development (BDD) and why it is useful.

Think about how BDD helps teams work together and understand requirements.

Describe the structure of a BDD scenario using Given-When-Then and what each part means.

Remember the three parts that tell a story about the feature.
