Dinosaur Museum Project

The Dinosaur Museum is opening! You've been tasked with building some challenging functionality for the automated systems recently installed at the museum.

To complete this project, you will need to write several difficult functions that will support attendees in finding out information about dinosaurs, finding the dinosaur's location, and calculating their entry fees.

51 unit tests need to pass. Each passing test will be worth 1 point.

A minimum of 36 points must be attained to pass this assessment.

There is no partial credit for the tests.

Project setup

Getting started

  1. Fork and clone this repository.

  2. Navigate to the cloned repository's directory on your command line. Then, run the following command:

    npm install

    This will install the libraries needed to run the tests.

  3. Open up the repository in VSCode. Follow the instructions below to complete the Lab.

Tests

To run the tests, you can run the following command from the command line. You will need to be in the root directory of your local directory.

npm test

This will run the test output once.

Test watcher

If you'd like, you can have the tests run constantly. This means that each time you save your file, your tests will be re-run. To do so, you can run the following:

npm run watch

Follow the on-screen prompts to exit out of the constant runner.

Run test files individually

There are a lot of tests that are contained in this project. You can run a single test file individually by putting the name of the file after npm test. You can even only put part of the file name.

npm test facts

Keep in mind that the testing framework, Jest, will attempt to match as many files as possible. So, for example, the following command will run all of the tests because all of the tests are inside of the dinosaur-museum-project/ folder.

npm test dinosaur

Run tests individually

After choosing a specific file to run, you can also specify which test you want to run. To do so, add .only after either test or describe.

test.only("should return an array of everyone's name who is in the line, in order", () => {

This will either run the specific test or, in the case of adding .only to a describe block, all of the tests for a specific function.

NOTE: Don't forget to remove this after you get the test to pass!

Run file

If you want to manually test out your file, you can do so by running the following command.

node index.js

The output will be printed to your terminal.

Instructions

Project overview

Each file under the src/ directory contains two or three functions that you will need to complete. Follow the JSDoc comments and tests to understand what needs to be completed.

Each of these functions is quite challenging. You will need to apply everything you've learned to solve each one.

Before you start coding, remember Polya's problem-solving methodology; begin by understanding the problem, then devise a plan. Only after accomplishing those two steps should you start writing your code.

Tips

  • \n represents a new line in text. For example, take a look at the following code.

    console.log("Each\nNew\nLine!");

    This will output in the following way:

    Each
New
Line!

  • Start small for each of the functions. Many of the functions require you to solve some edge cases. First, design a function that works for a single case and then expand outwards. Likely, you will incrementally have more and more tests passing, as opposed to all of them passing at once.
