In Part 2 of the assessment, we're going to write JavaScript. Specifically, we're going to define a pair of custom objects: Student and Classroom. Each of these custom objects will have properties and behaviors specific to itself. Tests have been written to guide you through the development of each object.
The tests describing the behaviors of our custom objects have been written using Jasmine, which might be unfamiliar to you. That's perfectly fine. We won't be writing any Jasmine tests today—just reading them. Jasmine's syntax is very similar to RSpec's; we'll see describe() and it()—only in JavaScript, not Ruby. When we call either of these functions, instead of passing a block as we would in Ruby, we'll pass a function.
The files containing the tests are located within the spec/ directory; the files are named student-spec.js and classroom-spec.js. Read through them as you need to.
We won't run the tests from the command line. Instead we'll run them in the browser, by opening the file SpecRunner.html. This HTML file loads the Jasmine JavaScript library, the application code that we'll write, and the files containing the tests. It runs the tests and then displays the outcome of the tests in the browser.
We'll start by focusing on the tests describing our student (see spec/student_spec.js). To run the tests, open the file SpecRunner.html in a browser. On the command line navigate to the part-2 directory and then run ...
$ open SpecRunner.html
... this should open the HTML file in the default browser.
When the page loads, the tests will run—to begin, all of them will be failing. Writing code in the file student.js, work through the tests until all of the tests for the student pass.
Once the tests for the custom student object pass, move on to the classroom object type. Write the code for the custom classroom object in the file classroom.js. Work through the tests until all of the tests pass.
Once all the tests have passed, you have completed Part 2 of the assessment. If you haven't done so already, commit your changes and move on to Part 3.
