Mocha

Mocha is commonly the name of a chocolate-flavored coffee beverage. In contemporary coffee culture, a mocha is usually an espresso-based drink with steamed milk and chocolate, sometimes prepared with cocoa powder or chocolate syrup and topped with whipped cream. The term is historically linked to the port Mokha on Yemen’s Red Sea coast, a major center of early coffee trade, and the word mocha is also used to describe a brown color resembling the beverage.

Mokha (also spelled Mocha) is a port city on Yemen’s Red Sea coast, known in world history as a major export hub for coffee beans from the 15th century onward. Coffee traders shipped Mokha beans to the Ottoman Empire and Europe, helping popularize coffee. In various sources the association spread to the flavor profile, yielding the term mocha to describe blends of coffee and chocolate.

Mocha is also the name of a JavaScript test framework for Node.js and for the browser. Mocha provides a simple API for writing asynchronous tests in either a BDD or TDD style; tests are run in a Node.js process or in a browser environment. It integrates with assertion libraries such as Chai or Node’s built-in assert, supports multiple reporters, and allows features like hooks and asynchronous test completion via callbacks, promises, or async functions. It is distributed as an npm package and is widely used for unit and integration testing in JavaScript projects.
