URL Parser

In this project we will learn a variety of topics that range from test driven development to object oriented programming, and take a look ahead to some of next weeks topics.

The Assignment

Before you go any further, take a look at the Url Parser Infographic to get a better grasp on the parts of a url.

The goal of the assignment is to be able to instantiate a new instance of the UrlParser class by passing it a string url, and then be able to access all of the parts of the url from that new object.

For example, I should be able to do the following:

Instantiate a new instance of a UrlParser

    github_url = UrlParser.new "https://github.com/search?q=ruby#stuff"

Calling the following methods on that instance should return the following results:

    github_url.scheme
    => "https"
    github_url.domain
    => "github.com"
    github_url.port
    => "443"
    github_url.path
    => "search"
    github.query_string
    => {"q" => "ruby"}
    github_url.fragment_id
    => "stuff"

Pass all the provided rspec tests.

Setting Up

From the the terminal cd into your wyncode folder
Once inside the wyncode folder, create the directory for your new project

    mkdir url_parser
    cd url_parser

Now that you have an empty directory for your new project, we are going to set up the proper file structure. Inside of the url_parser folder, create a file named url_parser.rb

    touch url_parser.rb

Great! Now lets create the spec folder for our test file, and touch the spec file inside that folder

    mkdir spec
    touch spec/url_parser_spec.rb

Boom! We should have the proper directory structure set up for our project. Let's open our app in our text editor

    atom .
    #or subl .

Next we need to copy the code from the file below into our spec/url_parser_spec.rb file.
URL Parser Spec

Getting Started

Now that we have the rspec tests in the proper place we need to require the url_parser.rb at the top of the spec file.
Great! Now in your terminal run the tests by executing the command :

    rspec -fd -c

This should throw us an error `Uninitialized constant UrlParser(nameError)`. That's because we haven't made the `UrlParser` class yet in the `url_parser.rb` file.

Create that class, run the spec again and we should see a bunch of failing tests!
We're off to the races, now go write the code to make all those tests pass!

Advice

Good luck! Remember our process of red, green, refactor. Work on one test at a time, get that spec to pass, then refactor. Then move on to the next test.

Oh, and do not change the tests!
