The advantages of Behavior Driven Development are best realized when non-technical users such as Business Analysts use BDD to draft requirements and provide the same to the developers for implementation.
In Agile methodology, user stories can be written in the format of feature file and the same can be taken up for implementation by the developers.

We may execute a single test from a set of tests in the Cucumber framework using the tags idea. This is found in the TestRunner file's @CucumberOptions section. With the use of the @t<agname> keyword, we may tag a scenario in the feature file. A scenario can have one or more tags within the feature file. We can separate test scenarios with the assistance of tagging. We must pass the <tagname> value within the tags argument to execute a selected test in Cucumber, and we must pass the <~tagname> value within the tags parameter to exclude a test from running.

Despite the fact that Cucumber and JBehave have the same goal in mind, acceptance tests are two quite distinct frameworks:
* Cucumber is built on Ruby, while JBehave is a pure Java Framework.
* Cucumber is built on features, whereas JBehave is based on stories.

TDD is an abbreviation that stands for Test-Driven Development. This is a development practice in which the test cases are created first, followed by the code that underpins the test cases. TDD may also be used to construct automation testing. TDD takes longer to develop due to the fact that it finds fewer flaws. The TDD development practice has increased the quality of code, which is more reusable and flexible as a result. TDD also aids developers in achieving high test coverage, ranging from 90% to 100%. The sole disadvantage of TDD for developers is that they must build test cases before producing code.
The following is a list of the TDD methodology's basic six-step process:
First, all the test cases are written. Based on your requirements, you must create an automated test case.
Carry out all of the tests: Carry out these automated test cases on the code that has been developed so far.
Modify the code for that test case: You must develop the code to make that test casework as intended if it fails throughout this step.
Rerun the test cases: Now you must rerun the test cases to ensure that all of the previously developed test cases have been implemented.
Modularize your code as follows: This is a step that can be skipped. However, refactoring your code to make it more readable and reusable is recommended. That is why it is necessary.
For new test scenarios, repeat steps 1–5: This is the final phase in the process. You must now repeat the process for the remaining test cases till all of them have been implemented.

Hooks are code blocks that execute before or after each Cucumber scenario in the execution cycle. This enables us to better control the development workflow and decrease code redundancy. Setting up the web driver and terminating the web driver session resembles a test setup. When dealing with different scenarios, it's best to do the setup and clean up only once. Hooks are used to bringing optimization.
Certain preconditions, such as executing the program, creating a database connection, preparing the test data, and so on, may be required in some cases. There are also several postconditions to be fulfilled, such as ending the database connection, closing the browser, refreshing test data, and logging out of the program. Cucumber handles all of these situations with the use of hooks.

Following is an example of a feature file for the scenario ‘Login into the application’:
Feature: Login to the application under test.
Scenario: Login to the application.
* Open the Chrome browser and launch the application.
* When the user enters the username onto the UserName field.
* And User enters the password into the Password field.
* When the user clicks on the Login button.
* Then validate if the user login is successful.

A comment is a chunk of code that is intended for documentation rather than execution. To make it more legible and clear, whether it's a step definition file or a feature file. As a result, it's critical to use/insert comments in the right places throughout the file. This is also beneficial for troubleshooting the code. Comments can be added to Cucumber feature files at any time. To add comments, simply begin the statement with the “#†sign.
Different programming languages have different standards for commenting. Let's see how Cucumber handles the situation:
* For Step Definition File, if you're using Java as a platform, start your comments with "/."
* In the case of a feature file, we only need to type # before starting our comment.

A step definition file in Cucumber is used to segregate the feature files from the underlying code. Each step of the feature file can be mapped to a corresponding method on the Step Definition file.
While feature files are written in an easily understandable language like, Gherkin, Step Definition files are written in programming languages such as Java, .Net, Ruby, etc.

The following are the files required for a Cucumber framework:
<> Feature File: It has plain text descriptions of single or numerous test situations. Keywords like Then, When, Background, Scenario Outline, Feature, And, But, and so on are used in the tests. As a result, it's a file that keeps track of features and their descriptions.
<> Step Definition File: It has the extension .java. It essentially acts as a translator between the test scenario steps provided in the feature file and the automation code. Cucumber searches the step definition file and executes the relevant functions that are assigned to that step when it runs a step described in the feature file.
<> TestRunner: .java is the file extension for this file. It connects the feature file and the step definition file. It allows the user to run one or more feature files at the same time. It contains the locations of the step definition and feature files.
Posted Date:- 2021-10-16 08:01:55
Step definitions connect Gherkin steps to programming code. The mapping between each step of the scenario defined in the feature file and a code of the function to be executed is stored in the steps definition file. A step definition carries out the action that should be performed by the step. So step definitions hard-wire the specification to the implementation.

Step definition maps the test case steps in the feature files(introduced by Given/When/Then) to code which executes and checks the outcomes from the system under test.
A step definition is analogous to a method defined in any kind of Object Oriented programming language.
Step definition is defined in ruby files under features/step_definitions/*_steps.rb".

Consider the situation when we need to run a test scenario multiple times. Assume we need to ensure that the login feature is functional for all types of subscribers. This necessitates repeating the login functionality scenario. Copying and pasting the identical instructions to just re-run the code does not appear to be a good approach. Gherkin adds another framework, the scenario outline, to help with this. The scenario outline is similar to scenario, with the exception that several inputs are provided.
Example:-
Scenario Outline - Sign In Feature for a website.
Explanation: The website can have multiple users and so we need to consider all the users while implementing the sign-in functionality.

Scenario is a fundamental Gherkin structure. Every scenario begins with the keyword "Scenario:" (or a localized version of it) and ends with a scenario title. Every feature can have one or more scenarios, each of which has one or more steps.
As an example of a scenario, consider the following:
Scenario − Verify My Orders Functionality.
Explanation: When a user clicks on the My Orders option he/ she should be taken to the My Orders page.

Behaviour Driven Development (BDD) is a synthesis and refinement of practices stemming from Test Driven Development (TDD) and Acceptance Test-Driven Development (ATDD). BDD augments TDD and ATDD by
applying the “Five Why’s†principle to each proposed user story so that its purpose is clearly related to business outcomes. Five Why's is an iterative interrogative approach for uncovering the cause-and-effect links at the root of a problem. The main purpose of this technique is to uncover the core cause of a flaw or problem by asking "Why?" repeatedly. Each response serves as the foundation for the next question.

Cucumber is a behavior-driven development (BDD) testing tool. The BDD framework's major goal is to bring together a variety of project responsibilities, such as quality assurance, developers, and business analysts, to understand the application without diving too deeply into the technical components.
Testers use Cucumber to create test cases for evaluating program behaviour. It is an important tool to automate acceptance tests written in logical language that customers can understand. It's primarily used to develop acceptance tests for web apps based on their features' behaviour.
