gherkin-detailer

gherkin-detailer is a powerful tool designed to analyze and optimize your gherkin files within a project. It helps you maintain a clean and efficient codebase by providing an overview of your gherkin files and highlighting potential duplications.

Documentation

• Summary

Introduction

gherkin-detailer is a tool that generates comprehensive HTML reports for the gherkin files in your project. These reports help you manage and optimize your gherkin scenarios, ensuring a cleaner and more efficient codebase. The tool currently provides six detailed sections:

• Files List: Contains the entire list of all detailed scenarios.
• Features List: Provides a simple list of all the features.
• Scenarios List: Offers a simple list of all scenarios and scenario outlines.
• States List: Lists all the Given states.
• Actions List: Lists all the When actions.
• Outcomes List: Lists all the Then outcomes.

Each detail in these sections is color-coded to highlight potential similarities, helping you identify and address code duplication within your project.

Examples

Example: Files Section

The Files section lists all the gherkin scenarios across all *.feature files in your project. This page serves as a comprehensive documentation of your project, organized by file and detailing all specific use cases.

Color Coding

The color coding provides additional insights into the gherkin elements:

• Red: Indicates elements that are identical across all gherkins. These elements (actions, outcomes, scenarios, etc.) represent the same entity across different files, suggesting that there should be a single, specific piece of code associated with all of them. Developers should ensure that these red-highlighted elements are consistently implemented and do not require multiple definitions.

• Orange: Highlights elements that are similar across gherkins. These elements may represent different entities but with some common attributes. Developers should review these orange-highlighted elements to verify whether the similarities are accurate and whether they truly represent distinct entities with different code. This check helps prevent potential errors and code duplication.

Example: Actions Section

The Actions section lists all the actions (When steps) present in your gherkin files. This page helps developers quickly locate and review all the actions defined across the project.

Navigation Menu

The navigation menu allows developers to efficiently move between different sections of the report:

• Files: Provides a general overview of all gherkin files in the project.
• Features: Lists all the features present in your gherkin files.
• Scenarios: Displays all scenarios and scenario outlines.
• States: Shows all Given states.
• Actions: Lists all When actions (this section).
• Outcomes: Lists all Then outcomes.

This menu enables you to switch between sections to gain detailed insights into specific elements of your gherkin files, allowing for thorough analysis and easy navigation throughout the project.

Requirements

• node 10.12+
• npm 6.0+

Installation

gherkin-detailer can be installed as a global tool:

$ npm install -g gherkin-detailer

$ yarn global add gherkin-detailer

or as a devDependency:

$ npm install -D gherkin-detailer

$ yarn add --dev gherkin-detailer

Usage

If you’ve installed it as a devDependency, you need to add it in the script section of the package.json.

To execute it with all default options, so to let its analysis starts from the current folder, set this up:

"gherkin-detailer": "gherkin-detailer"

To customize the analysis folder, set this up:

"gherkin-detailer": "gherkin-detailer -a './src/'"

To customize the output folder, set this up:

"gherkin-detailer": "gherkin-detailer -o './report/'"

To customize the report theme, set this up:

"gherkin-detailer": "gherkin-detailer -t 'black'"

Then the gherkin-detailer can be executed in order to have a gherkins report created in a default folder ./report/gherkin-detailer/

$ npm run gherkin-detailer

$ yarn gherkin-detailer

Help

$ gherkin-detailer --help
