To run the tests in your local machine

1. Clone the repo in your computer:

git clone https://github.com/Leninner/ioet-aplication.git

2. Install all the dependencies with:

To do this step, you need to have NodeJs in the last version: 16.13.1

npm install

3. In the path ./src/employeesInOffice.test.js, you will see:

const PATH = 'C:\\Users\\USUARIO\\Desktop\\ioet-aplication\\src\\data\\setsOfData.txt';

• You need to change the PATH const according the path of the setsOfData.txt file in your machine, then type in the terminal:

npm run test

If the last not run and you get an error, then comment the lines 3 to 5 and pause de first describe in the line seven and unpause the second describe in the line 50:

• The 3 lines for comment

const fs = require('fs');
const PATH = 'C:\\Users\\USUARIO\\Desktop\\ioet-aplication\\src\\data\\setsOfData.txt';
const arrayOfData = fs.readFileSync(PATH, 'utf8').split('\n');

• Pause the first describe in the line 7:

// From this

describe('some word', () => {
  /*some tests*/
});

// To this

xdescribe('some word', () => {
  /*some tests*/
});

• Unpause the second describe in the line 50:

// From this

xdescribe('some word', () => {
  /*some tests*/
});

// To this

describe('some word', () => {
  /*some tests*/
});

Then type in the terminal and see the results:

Synthesis of the solution

The goal of this challenge was to output the info containing pairs of employees and how often they have coincided in the office:

• Input:

• Output:

To solve this challenge I used Javascript, which is a multi-paradigm language and many paradigms that I used was:

• Imperative Paradigm: We tell the computer what I want step by step
• I divided the functions into modules for a better understanding of the problem
• I tried to use good practices like SOLID principles
• To do Test Driven Development I used Jest

Step By Step to solve the challenge

1. First of all, I need to know what data type I am receiving

   • I receive a string and the goal is to output an object with the result

/**
 * @param {String} value
 * @returns {Object}
 */

2. I need to structure the string in a way that I can work without any problem, to do that I need the Get Obj Structured function, that help me to structure the string as the following way:

// String
let data =
  'RENE=MO10:00-12:00,TU10:00-12:00,TH01:00-03:00,SA14:00-18:00,SU20:00-21:00|ASTRID=MO10:00-12:00,TH12:00-14:00,SU20:00-21:00|ANDRES=MO10:00-12:00,TH12:00-14:00,SU20:00-21:00';

let obj = {};

// Structured String

getObjStructured(obj, data);
/* {
    RENE: ['MO10-12', 'TU10-12', 'TH01-03', 'SA14-18', 'SU20-21'],
    ASTRID: ['MO10-12', 'TH12-14', 'SU20-21'],
    ANDRES: ['MO10-12', 'TH12-14', 'SU20-21'],
  };
*/

3. Next, I need the Get Final Result function that receive the structured object of the last step and help me to do a logical process and structure result object:

getFinalResult(obj): // { 'RENE-ASTRID': 2, 'RENE-ANDRES': 2, 'ASTRID-ANDRES': 3 }

This two functions:

getObjStructured(obj, value);
getFinalResult(obj);

Are use by the Employees in Office function for get the final Result

• Litle Synthesis:

1. Structure data
2. Getting final result

Test Results

Conclusions and Recommendations

This challenge was very useful for me. Was useful because I could improve my logical thinking and feel challenged to do the best I could, even though the exercise was complex for me.

After this problem, I am left with a huge desire to continue improving my development skills.

As recommendation:

• Specify which are the data type of the inputs and the outputs of the challenge.
