## Testing
### Replit
Most of this project was developed using Replit and so testing was done as I was building the project step by step.
### Manual Testing
The following manual tests were conducted to ensure the application works as expected:
#### Test 1: Welcome Message
**Steps:**
1. Run the application.
2. Observe the welcome message displayed in the console.
**Expected Result:**
- The welcome message should be centered and displayed with appropriate colors.
**Actual Result:**
- The welcome message is displayed correctly.
**Screenshot:**

#### Test 2: High Scores Display
**Steps:**
1. Run the application.
2. Observe the high scores displayed after the welcome message.
**Expected Result:**
- The high scores should be displayed in a centered format with appropriate colors.
**Actual Result:**
- The high scores are displayed correctly.
**Screenshot:**
![High Scores](readme/welcome.jpg)
#### Test 3: Board Size Input
**Steps:**
1. Run the application.
2. Enter a valid board size (between 5 and 9).
**Expected Result:**
- The application should accept the input and proceed to the next step.
**Actual Result:**
- The application accepts valid inputs and proceeds correctly.
**Screenshot:**
![Board Size Input](readme/board_size.jpg)
#### Test 4: Invalid Board Size Input
**Steps:**
1. Run the application.
2. Enter an invalid board size (outside the range of 5 to 9).
**Expected Result:**
- The application should display an error message and prompt for input again.
**Actual Result:**
- The application displays an error message and prompts for input again.
**Screenshot:**
![Invalid Board Size Input](readme/board_size.jpg)
#### Test 5: Player Turn
**Steps:**
1. Run the application.
2. Enter valid coordinates for the player's turn.
**Expected Result:**
- The application should update the board and display the result (hit or miss).
**Actual Result:**
- The application updates the board and displays the result correctly.
**Screenshot:**
![Player Turn](readme/player_turn.jpg)
#### Test 6: Computer Turn
**Steps:**
1. Run the application.
2. Observe the computer's turn.
**Expected Result:**
- The application should update the board and display the result (hit or miss).
**Actual Result:**
- The application updates the board and displays the result correctly.
**Screenshot:**
![Computer Turn](readme/player_turn.jpg)
#### Test 7: Game Over
**Steps:**
1. Run the application.
2. Play the game until either the player or the computer wins.
**Expected Result:**
- The application should display the game over message and the final scores.
**Actual Result:**
- The application displays the game over message and the final scores correctly.
**Screenshot:**
![Game Over](readme/game_over.jpg)
#### Test 8: Save High Score
**Steps:**
1. Run the application.
2. Win the game and choose to save the high score.
3. Enter a name when prompted.
**Expected Result:**
The application should save the high score to the Google Sheets and display a success message.
**Actual Result:**
The application saves the high score and displays the success message correctly.
**Empty Username:** Players can intentionally leave the username field empty if they prefer not to submit a name. The high score will still be recorded on the leaderboard with a blank entry for the name.

### PEP 8 Compliance
The project's Python code has been refactored to improve adherence to PEP 8 style guidelines. This enhances readability and maintainability. Specific improvements include:
* **Reduced Branching:** Complex conditional logic, particularly in the `display_boards` function, has been simplified to reduce the number of branches, improving code clarity.
* **Modernized String Formatting:** F-strings (formatted string literals) have been adopted throughout the codebase for more concise and readable string formatting.
* **Removed Redundant Code:** Unnecessary `else` clauses following `return`, `break`, and `continue` statements have been eliminated.
* **Import Order:** Imports have been reorganized to follow PEP 8 recommendations (standard library imports first, followed by third-party and then local imports).
These changes were guided by feedback from the `pylint` static analysis tool.

## Future
### Potential Future Features
* **Player vs. Player:** Perhaps add functionality to allow for a 2 player turn-based mode
* **Various Ship Sizes:** It would be nice to add different dized ships more akin to traditional Battleships game, with a choice of orientation
* **Number of Ships:** The added functionality to not only choose the board size but to also choose how many ships on the board would also be an attractive addition to the game
* **Choose Ship Placement:** The option to decide where you would like to place your ships on the board would also be a nice future feature to incorporate

## Deployment
The site was deployed to Heroku. The steps to deploy are as follows:
- Set up a [Heroku](https://dashboard.heroku.com) Account and create a new App
- In Settings add the python and nodejs buildpacks
- In `Settings > Config Vars` Add the creds.json contents under the variable `CREDS`
- Link the [GitHub repository](https://github.com/hedgemonkey/battleships) to the Heroku app.
Heroku git URL
[https://git.heroku.com/battleships-hedgemonkey.git]
The live link can be found [here](https://battleships-hedgemonkey-131f157c44ae.herokuapp.com/)

### Google Docs
This project uses a `Google Sheets` spreadsheet hosted on `Google Docs` accessed by `Google Cloud API` this is to keep track of past scores.
In order to deploy this yourself you would have to get the correct credentials to access this file or specify your own spreadsheet and provide your own Google Cloud API Credentials
To do this you ned to save your own credentials to `creds.json` and change the line `SHEET = GSPREAD_CLIENT.open('battleship_scores').sheet1` replacing `battleship_scores` with your own spreadsheet filename
The spreadsheet can be access [HERE](https://docs.google.com/spreadsheets/d/1cUhnYhy8DuxIEW6_BLnj0OFL38dNoRqmyVvkgnQDai8/edit?usp=sharing)
