Im nächsten Schritt integriert man seine Quell- und Spec-Dateien, die den zu testenden Quellcode beziehungsweise die Tests enthalten. Looking at the code from the divide() function, I realize I can re-write that code in a single line using a JavaScript ternary operator. The first parameter is a name for the test "suite", and tells Jasmine (and yourself/other programmers) that everything inside this describe block is dealing with the calculator part of your application. Dieses Framework ist verhältnismäßig weit verbreitet, unterstützt den testgetriebenen Entwicklungsansatz, kann im Zusammenspiel mit jedem anderen Framework verwendet werden und hängt von keinem anderen Framework und keiner anderen Bibliothek ab. This file should be loaded after jasmine.js and jasmine_html.js, but before any project source files or spec files are loaded. This work is inspired by: Protractor Jasmine 2 Screenshot Reporter from @mslison; Jasmine Reporters from @larrymyers; Usage. Erfahren Sie, wie Sie Ihre korrekte Version von jasmine-html.js herunterladen und ersetzen sowie wie Sie diese ärgerlichen JS … However, without tests refactoring can be a huge pain because you'll need to manually check everything you've written to make sure everything else still works. Now your SpecRunner.html should look like this: and your src and spec folders should be empty. After it finished downloading, unzip the file and move it to a logical place in your computer. Jasmine is a little behavior-driven development (BDD) test framework created by the developers at Pivotal Labs, to allow you to write automated JavaScript unit tests. The jasmine-standalone files come with example JavaScript files and test specs called PlayerSpec.js, SpecHelper.js, Player.js, and Song.js. In diesem Artikel soll das Framework Jasmine zur Anwendung kommen. If we have an existing complex AngularJS single-page application, for example, we're not going to want to change around the location of all the Angular files and deal with all the errors that pop up because of it just so we can add unit tests. We named our project as Jasmine_Demo. Now just change the test to the correct value (expect(subtract(3, 2)).toBe(1);) and watch the tests pass: Let's add a multiplication and division test. Others include qUnit, jQuery's "unofficial official" testing framework, and YUI Test, which is part of Yahoo YUI library. If we were testing Angular, we might put all tests for a single Angular Service (perhaps a UserService, for example), inside one describe block. It provides utilities that can be used to run automated tests for both synchronous and asynchronous code. As jasmine-html has jasmine as a dependency it will then proceed to load jasmine.js, then jasmine-html.js and finally boot.js as it was doing on our original runner. In the calculator we only used the .toBe() matcher. Jasmin ist eine schen testing Framework für Javascript. For the Jasmine NPM module: https://github.com/jasmine/jasmine-npm For the Jasmine Ruby Gem: https://github.com/jasmine/jasmine-gem For the Jasmine Python Egg: https://github.com/jasmine/jasmine-py For the Jasmine headless browser gulp plugin: https://github.com/jasmine/gulp-jasmine-browser To install Jasmine standalone on your local box (where {#.#.#}below is substituted by the release number downloaded): 1. (expect(true).not.toBe(false) will run a passing test spec!). →, V School | Better Humans, Better Outcomes. Step 6. There are 3 very popular frameworks you can use for testing javascript: Jasmine, Mocha, and QUnit. Instead of repeating everything that's in the Jasmine introduction tutorial, you should take the time now to go check it out and see all the awesome matchers you have at your disposal. Jasmine can be used as a standalone application where you download the framework and put your JavaScript files inside the src folder. So let's go define it: Now you should have a failing expectation: "Expected 1 to be 3." We use matchers to do this. jquery backbone.js (1) . (This is like writing out if (true === true){... in JavaScript). However, Jasmine provides us with tons more to use. It's important to see your test fail before you make it work, so we'll make it fail again using the add() function from our calculator.js: You might wonder how this file knows about the add() function. In order to use Jasmine to test Node.js applications, a series of steps need to be followed. 2.4.1 is just the standalone version number used for this tutorial and thus it can vary. In our example below, we are going to define a module which adds 2 numbers which need to be tested. Also, open SpecRunner.html and delete the 4
