Gherkin Language: Format, Syntax & Gherkin Test in Cucumber

What is Gherkin Language, and how does it work?
Gherkin is a business-readable language that allows you to describe business activity without having to get into the specifics of how it will be implemented. It is a domain specific language for defining tests in the Cucumber format for specifications, and it is used in the software industry. It describes use cases in plain English and lets users to omit logic details from behaviour tests, allowing them to be more concise.

The material written in the Gherkin programming language serves as documentation and the skeleton for your automated tests. The Gherkin format is based on TreeTop Grammar, which is used in more than 37 different languages. As a result, you can write your gherkin in any of the 37 or so spoken languages.

This script is intended to accomplish two key goals:

User scenarios are documented.
Making an automated test is a tedious task (BDD)
You will learn how to use Gherkin in this video.

Syntax of the Gherkin
Gherkin is a line-oriented programming language, similar to YAML and Python. Each line is referred to as a step, and it begins with the keyword and ends with the stop symbol. Indentation is accomplished with the use of a tab or a space.

A comment can be put anywhere in this script, but it must begin with a # symbol in order to be recognised. Ghrekin’s keywords such as given, when, and so on were removed from each line before the programme began reading them.
The following are typical Gherkin steps:
Gherkin Scripts: Gherkin Scripts bridge the gap between the human understanding of cause and effect and the software concept of input, processing, and output.

Gherkin Syntax: Feature: The Scenario’s title is provided [together with any preconditions or initial context].
If [Event or Trigger] occurs, then [anticipated output] occurs.
A Gherkin document has the extension.feature, and a test file with a fancy extension is simply a test file with a fancy extension. Cucumber reads a Gherkin document and then runs a test to ensure that the programme behaves in accordance with the syntax defined in the Gherkin document.

The feature name is given according to the naming convention. Cucumber, on the other hand, does not have any hard and fast rules when it comes to names.

Feature: The file should have the extension.feature, and each feature file should contain a single feature in total. It is necessary to start with the feature keyword and then add a space before writing the name of the feature.

Scenario: Each feature file may contain numerous scenarios, and each situation begins with the prefix Scenario: followed by the name of the scenario being discussed.

Background: Using the background keyword will allow you to provide some context to the situation. Some steps from the scenario can be included in this script, but the only difference is that it should be run before each scenario.

Provided: The purpose of using the Given keyword is to place the system in a familiar state before the user begins interacting with the system. Unless otherwise specified in the “Precondition” step, you may choose to skip writing user interactions in the Given phases.

Syntax:

Given Given – a test step that establishes the ‘context Given I am now on the “/” command line.
When: When the step’s purpose is to define the action taken by the user.

Syntax:

When A When is a test step that defines the ‘action’ that is done when I perform the action “Sign In.”
The use of the ‘then’ keyword is to examine what happens after the action in the when step has been completed. You may, however, only verify modifications that are immediately obvious.

Syntax:

Then Then is a test step that defines what is meant by the term ‘result.’
After that, I should watch “Welcome Tom.”
And & But It is possible to have many instances of when or then.

Syntax:

However, there is an additional test phase that defines the ‘action’ and ‘result.’
However, I should watch “Welcome Tom.”
Additionally, there is an additional test step that defines the ‘activity’ that was executed.
In addition, I type “EmailAddress” with the address “Tomjohn@gmail.com.”
The steps Given, When, Then, and, but are all tests. You can use them both in the same sentence. There are no errors displayed by the interpreter. When they are read, they will almost certainly not make any’sense.’
