Angular 2 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>
