Ioet Acme Exercise

This projects consists on an simple application to solve a programming exercise.

Requirements

To run this project make sure you have installed on your os:

 python >= 3.8.10

Running the app

To actually run the project clone it in your desired folder

 https://github.com/mateusjs/ioet.git

Open the project, and a bash inside the root folder, then using the bash change to the app dir.

cd app

NOTE: Do not change the file name file.txt within data folder, it is the file to run the program correctly, so if you want to change the input, just edit the file.

Execute the file main.py file to run the application.

python main.py

After runit, a new file called employees_payment.txt will be generated on the data folder with the output. On your bash you can also check the output.

Tests

The project has a coverage of 100%, to run the tests you need to be inside the app dir.

Then run the following command.

python -m unittest discover test/

Exercise

The company ACME offers their employees the flexibility to work the hours they want. They will pay for the hours worked based on the day of the week and time of day, according to the following table:

Monday - Friday	Payment per hour	Saturday and Sunday	Payment per hour
00:01 - 09:00	25 USD	00:01 - 09:00	30 USD
09:01 - 18:00	15 USD	09:01 - 18:00	20 USD
18:01 - 00:00	20 USD	18:01 - 00:00	25 USD

The goal of this exercise is to calculate the total that the company has to pay an employee, based on the hours they worked and the times during which they worked. The following abbreviations will be used for entering data:


Day	MO: Monday	TU: Tuesday	WE: Wednesday	TH: Thursday	FR: Friday	SA: Saturday	SU: Sunday

Input: the name of an employee and the schedule they worked, indicating the time and hours. This should be a .txt file with at least five sets of data. You can include the data from our two examples below.

Output: indicate how much the employee has to be paid

For example:

Case 1 Input: RENE=MO10:00-12:00,TU10:00-12:00,TH01:00-03:00,SA14:00-18:00,SU20:00-21:00 Output: The amount to pay RENE is: 215 USD

Case 2 Input: MO10:00-12:00,TH12:00-14:00,SU20:00-21:00 Output: The amount to pay ASTRID is: 85 USD

Solution

For the solution first i tried to see what could be done with the data and requirements collected, so then i could create a simple structure that would be easy to understand and also to code.

Using a c4 model, i was able to create the mvp structure of the project

With that in mind became easy code, so i created a component to process the file (read and write), after that i start to developing the next steps, creating some objects to handle the input processed.

While coding was possible notice the lack of some helper functions, so i created it.

After finishing to code, and test, i start to improve the app with some actions and documentation.

The idea of the solution is to get the value of the multiplier for each hour worked on each day.

So i splitted the input by day, then for each hour i check the amount to pay and add it to the total.
