cucumber-expression-extender

Prerequisites | Installation | Manual

Cucumber expression extender is a simple Cucumber's plugin to extend the tags expressions for easier feature files writings.

Why

It helps writing cleaner feature files without complex regular expressions.

Writing something like

Given 21-11-2015 is nice

can be translated by

Given('{dd-mm-yy} is nice '

Instead of:

Given(/^(\d+)\-(\d+)\-(\d+) is nice$/

Prerequisites

In order to use this plugin:

• Cucumber must be installed.

Installation

To install the plugin to your project please use:

npm install cucumber-expression-extender

Manual

Once Cucumber expression extender is installed,

you can require it in your project:

require('cucumber-expression-extender');

And that's it,

you can now integrate it in your step definitions:

Given('{dd-mm-yy} is a nice date', 
(dateObject) => {
    console.log('indeed nice date ',
        dateObject.toString());
});

And you can use the new step in feature file

Given 01-02-21 is a nice date
