Jasmine TDD

#Directory structure and initialization

In the project root directory, run

jasmine init

This creates two directories and a file:

spec/support/jasmine.json

Next, create two files:

touch spec/spec.js
touch app.js

The directory should now look like:

spec/support/jasmine.json
spec/spec.js
app.js

#app.js app.js is an object of keys and methods. The name of the object is module.exports.

module.exports = {
  nameOfTest: function() {
    // code goes here;
    return anyName;
  },
  anotherTest: function() {
    // more code;
    // return somethingElse;
  }
};

#spec.js In spec.js:

var app = require('./../app.js');

var inputData = ['red', 'green', 'blue'];

describe('Test nameOfTest', function() {
  it('Description of code', function() {
    expect(app.nameOfTest(inputData)).toEqual(outputData);
  });
});

var moreInputData = [...]

describe('Test anotherTest', function() {
  it('Description of code', function() {
    expect(app.nameOfOtherTest(moreInputData)).toEqual(outputData);
  });
});

#Run jasmine Run the tests from the root directory with the command
