Jasmine is an open source unit testing framework for JavaScript.[3] It aims to run on any JavaScript-enabled platform, to not intrude on the application nor the IDE, and to have easy-to-read syntax. It is heavily influenced by other unit testing frameworks, such as ScrewUnit, JSSpec, JSpec, and RSpec.[4]
Usage
Jasmine aims to be easy to read. A simple hello world test looks like this:
describe('Hello world', function() {
it('says hello', function() {
expect(helloWorld()).toEqual("Hello world!");
});
});
Jasmine has a number of other features, such as custom matchers, spies, and support for asynchronous specifications.
Matchers
As of version 1.1, the Jasmine framework supports the following matchers, as well as the addition of other custom matchers. [5]
toEqual
it("converts inches to centimeters", function () {
expect(Convert(12, "in").to("cm")).toEqual(30.48);
});
toThrow
it("throws an error when passed an unknown to-unit", function () {
var testFn = function () {
Convert(1, "cm").to("furlongs");
}
expect(testFn).toThrow(new Error("unrecognized to-unit"));
});
toBeDefined / toBeUndefined
it("is defined", function () {
var name = "Andrew";
expect(name).toBeDefined();
})
it("is not defined", function () {
var name;
expect(name).toBeUndefined();
});
toBeTruthy / toBeFalsy
it("is true", function () {
expect(Lib.isAWeekDay()).toBeTruthy();
});
it("is false", function () {
expect(Lib.finishedQuiz).toBeFalsy();
});
toBeLessThan / toBeGreaterThan
it("is less than 10", function () {
expect(5).toBeLessThan(10);
});
it("is greater than 10", function () {
expect(20).toBeGreaterThan(10);
});
toMatch
it("outputs the right text", function () {
expect(cart.total()).toMatch(/\$\d*.\d\d/);
});
toContain
it("should contain oranges", function () {
expect(["apples", "oranges", "pears"]).toContain("oranges");
});
