Practice task: Fixtures for CoffeeCart tests

Preparation:

1. Open the forked repo in VSCode.
2. Create a new branch: git checkout -b added_article_test
3. Run the installation commands npm ci & npx playwright install.

Main task:

1. Create fixtures.ts file under the ./tests/fixtures folder.
2. Create fixtures for the page classes initialization:

• menuPage
• cartPage

3. Create constants.js file under the ./src folder:

• This file should export a constant object of coffee prices, example: { espresso: 10, cappucino: 19}.

4. Create helper method getPriceForQuantity under src/common/helpers/getPriceForQuantity.ts folder. This file should have three functions: unitPriceFormatStr, priceFormatStr, totalPriceFormatStr

• First: get as input unitPrice and unitsNumber, return a formatted price, example of output: 10.00 x 1.
• Second: get as input unitPrice, return a formatted price, example of output: $10.00.
• Third: get as input unitsNumber, return a formatted price, example of output: Total: $10.00.

5. Update all the tests to use corresponiding fixtures for classes initialization.
6. Update all the tests to use prices from constants and price formatting methods instead of hard-coded prices.
7. Re-run all your tests and make sure they pass after the updates.

Task Reporting:

1. Add and commit all your updates.
2. Push the code to the origin.
