describe and specs

We have seen tests suites in many tools in the previous chapters. In Jasmine, we use describe to start a test suite. describe is a global function, which takes two parameters—a string and a function. The string is the title for the suite and function contains all of the tests implementations. A test in Jasmine is known as spec. The parameter function in the describe function contains one or more specs. A spec is also defined by calling a global function it, which takes two parameters just like describe.

Let's take a look at the following code:

describe("Title of a Suite", function() {
// variables available for all specs
    var amountToConvert;
    var rateOfConversion;

// the function 'it' defines a spec 
    it("Title of a Spec", function() {
       // do some testing here
    });
    it("Another spec", function() {
       // do some testing here
          });
});

As seen from the preceding code, describe defined a suite and specs were defined using it. To make these...
