JsGiven aims to bring BDD (Behavior-Driven Development) to plain (or typed) JavaScript.
It is a developer-friendly and pragmatic BDD tool for JavaScript.
Developers write scenarios in plain JavaScript using a fluent, domain-specific API, JsGiven generates reports that are readable by domain experts.
It's a JavaScript port of JGiven (written in Java). JsGiven keeps the JGiven philosophy, concepts and uses its html5 reporting tool.
You can have a look at JSGiven's own report
scenarios('recipes', RecipesStage, ({ given, when, then }) => ({
a_pancake_can_be_fried_out_of_an_egg_milk_and_flour: scenario({}, () => {
given()
.an_egg()
.and()
.some_milk()
.and()
.the_ingredient('flour');
when()
.the_cook_mangles_everything_to_a_dough()
.and()
.the_cook_fries_the_dough_in_a_pan();
then().the_resulting_meal_is_a_pan_cake();
}),
}));It can be used with any javascript test runner (like Jest, Ava, Mocha, Jasmine, or Protractor).
It can be used with your favorite assertion library (like ChaiJS, Jasmine), or your framework's assertion library.
It aims to provide the most comfortable developer experience with ES6 class syntax, and optional FlowType or TypeScript typings.
Some features are missing, but the folks at https://www.fluo.com are already using it daily.
