Introduction to Jasmine framework

Jasmine is a behavior-driven development framework for testing JavaScript code. This is how the official site explains Jasmine:

Jasmine is a behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks. It does not require a DOM. And it has a clean, obvious syntax so that you can easily write tests.

The general syntax of a Jasmine test suite is given as follows:

describe("Sample Test Suite", function() {
 it("This is a spec that defines test", function() {
   expect statement // asserts the logic etc
 });
});

Let's analyze the preceding code snippet to understand the test suite syntax. The following steps have been followed:

1. Every Jasmine test suite will have a describe statement, where we can give a name.
2. Inside the test suite, we create smaller tests cases using the it statement; each test case will have two parameters, a name and a function, which will have our application logic that needs be tested...
