Test task for Sigma Software
============================

[](#test-task-for-sigma-software)

This library allows to create a POS Terminal and count a price for a shopping cart depending on different pricing strategies.

How to install
--------------

[](#how-to-install)

```
composer require "feriatos/sigma-test-task:*"

```

How to use
----------

[](#how-to-use)

First create pricing strategies and add products:

```
$pricing = new OneTierPricing();
$pricing->addProduct(new OneTierProduct('ZA', 2, 7, 4));
$pricing->addProduct(new OneTierProduct('YB', 12));
$pricing->addProduct(new OneTierProduct('FC', 1.25, 6, 6));
$pricing->addProduct(new OneTierProduct('GD', 0.15));
```

Then create a terminal and set pricing:

```
$terminal = new POSTerminal();
$terminal->setPricing($pricing);
```

Scan items:

```
$terminal->scanItem('ZA');
$terminal->scanItem('YB');
$terminal->scanItem('FC');
$terminal->scanItem('GD');
$terminal->scanItem('ZA');
$terminal->scanItem('YB');
$terminal->scanItem('ZA');
$terminal->scanItem('ZA');
```

And get a result:

```
$totalPrice = $terminal->getTotal();
```

To clean items call:

```
$terminal->resetItems();
```

How to extend
-------------

[](#how-to-extend)

This library utilizes Strategy design patter. You could extend it just implementing `PricingInterface` and `ProductInterface` and add your own pricing strategy (for example two or three tiers pricing strategy).
