Chapter 1, Writing Feature Files, covers unique aspect of Cucumber – the Gherkin language and usage of Gherkin language to write meaningful and smart Feature files. This chapter will also cover different keywords, such as files Scenario, Steps, Scenario Outlines, and Data Tables.

Chapter 2, Creating Step Definitions, covers basic concepts and usage of Glue Code/Step Definitions, and regular expressions to come up with efficient and optimized Step Definitions. This chapter will also elaborate the concept of String and Data Table transformations.

Chapter 3, Enabling Fixtures, covers the advanced concepts of implementing fixtures by Tags and Hooks. Here not only the individual concepts of Tags and Hooks are explained, but practical example of using Tags and Hooks combination is also explained.

Chapter 4, Configuring Cucumber, deals with integration of Cucumber with JUnit and the concept of Cucumber Options. Here you will learn various practical examples of using Cucumber Options and different types of reports that can be generated with Cucumber.

Chapter 5, Running Cucumber, covers topics of running Cucumber from the Terminal and from Jenkins. You will learn Cucumber integration with Jenkins and GitHub to implement Continuous Integration and Continuous Deployment (CICD) pipelines. Then you will learn parallel execution to take full advantage of Cucumber.

Chapter 6, Building Cucumber Frameworks, covers detailed Steps to create robust test automation frameworks to automate web applications, mobile applications, and REST services.

Before starting with Cucumber, let's make sure that we have all the necessary software installed.

The pre-requisites for Cucumber are as follows:

This book is intended for business and development personnel who want to use Cucumber for behavior-driven development and test automation. Readers with some familiarity with Cucumber will find this book of most benefit.

Since the main objective of this book is to create test automation frameworks, previous experience in automation will be helpful.

In this book, you will find several headings that appear frequently (Getting ready, How to do it, How it works, There's more, and See also).

To give clear instructions on how to complete a recipe, we use these sections as follows:

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We can include other contexts through the use of the include directive."

A block of code is set as follows:

@When("^user enters \"(.*?)\" in username field$")
  public void user_enters_in_username_field(String userName) {
    //print the value of data passed from Feature file
    System.out.println(userName);
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

  Scenario: checking pre-condition, action and results
    Given user is on Application landing page
    When user clicks Sign in button
    Then user is on login screen

Any command-line input or output is written as follows:

mvn test -Dcucumber.options="--tags @sanity"

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the timestamp on the build. And then click on Console Output."
