# Testing Javascript with Jasmine

### unit testing

Independent checking for proper operation of the smallest testable part of an application.

* Independent: isolated from the rest of the system.

* Smallest testable: means you have to approach the all of code development from this prospective.

* Should be repeatable.

### mocking

Technique where dependency and its behavior is imitated (or faked).

* Can be done by the developer or a mocking library.

### Steps for Jasmine-based Tests

* Download and unzip Jasmine standalone into a directory.

[https://github.com/jasmine/jasmine/releases]()

* Erase everything in src and spec directories.

* Place your application code into the src directory.

* Place test code or a spec into the spec directory.

* Update SpecRunner.thml

    * Replace references to erased src and spec files with yours.

* Start Browser-sync (or whatever you use for local server) and go to the `http://.../SpecRunner.html` to have your specs run.

### Writing a Spec (test)

```

describe("My Function", function(){

    var initValue;

    beforeEach(function(){

        initValue = "someVal";

    });

    it("should not return true", function(){

        var result = someFunc(initValue);

        expect(result).not.toBe(true);

    });

});

```

#### _Summary_

* Unit testing is an essential process in any software dev. Planning for unit testing changes how you write code (for the better).

* Mocks are used to fake the dependencies of target code.

* `describe("message", function(){})` is to used to group tests together.

* `beforeEach(function(){})` is used to initialize state before running each test.

* `it("message", function(){actual test})` is used to run the actual test code.
