Angular 2 Testing an Angular 2 App Installing the Jasmine testing framework
Example
The most common way to test Angular 2 apps is with the Jasmine test framework. Jasmine allows you to test your code in the browser.
Install
To get started, all you need is the jasmine-core package (not jasmine).
npm install jasmine-core --save-dev --save-exact
Verify
To verify that Jasmine is set up properly, create the file ./src/unit-tests.html with the following content and open it in the browser.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<title>Ng App Unit Tests</title>
<link rel="stylesheet" href="../node_modules/jasmine-core/lib/jasmine-core/jasmine.css">
<script src="../node_modules/jasmine-core/lib/jasmine-core/jasmine.js"></script>
<script src="../node_modules/jasmine-core/lib/jasmine-core/jasmine-html.js"></script>
<script src="../node_modules/jasmine-core/lib/jasmine-core/boot.js"></script>
</head>
<body>
<!-- Unit Testing Chapter #1: Proof of life. -->
<script>
it('true is true', function () {
expect(true).toEqual(true);
});
</script>
</body>
</html>
