Introduction

In Cucumber Framework, business requirements are specified in Feature files, which are written in the Gherkin Language. So it becomes very important for us to understand the power and usage of the Gherkin language to come up with efficient and optimized Feature files.

This chapter will cover the usage of the Gherkin language to write meaningful and smart Feature files. We will start with some simple recipes to create a Feature file with one Scenario and will gradually move to recipes that are more complex where we create Feature files with multiple Scenarios, Backgrounds, and Scenario Outlines. We will also cover concepts and keywords, such as Feature, Scenario, Steps, Background, Scenario Outline and Data Tables.

Note

In this chapter, we will only focus on Feature files. Step Definitions and automation libraries will be covered in later chapters. Initially, you may not understand everything about the concepts in this chapter, but things will become clearer as you read on.
