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: [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");
});
