Laravel Type Coverage

Laravel Type Coverage is a package that helps you ensure your codebase has proper type hints and PHPDoc coverage. It analyzes your PHP files for missing type hints and doc comments, generating a report with insights on which functions need improvement.

Features

• Analyze your codebase for functions without PHPDoc and missing type hints.
• Display detailed coverage information with suggestions for improvement.
• Export the results to a JSON file.
• Supports configurable paths and exclusions for scanning.
• Command-line interface for easy integration into your workflow.

Installation

1. Install via Composer

To install the package, run the following command in your Laravel project:

composer require filipefernandes/laravel-type-coverage --dev

2. Publish Configuration (Optional)

If you want to customize the default configuration for the paths to scan, exclusions, or export options, you can publish the configuration file:

php artisan vendor:publish --provider="Filipefernandes\LaravelTypeCoverage\LaravelTypeCoverageServiceProvider" --tag="config"

This will create a config/type-coverage.php file where you can adjust the settings.

Usage

Run the Command

You can run the coverage analysis command with:

php artisan laravel-type-coverage:run

This command will scan your project for PHP functions and check if they have both type hints and PHPDoc comments. It will display a report in the terminal, showing the missing type hints and PHPDoc, along with suggested improvements.

Command Options:

• --path: Comma-separated list of paths to scan (e.g., app,src). If not provided, it will default to app.
• --fail-under: Set the minimum coverage percentage required to pass (default: 80).
• --ignore: Comma-separated list of paths to ignore.
• --export: Export the report to a file (default is true).

Example Usage:

php artisan laravel-type-coverage:run --path=app,src --fail-under=90 --export

Output Example:

When you run the command, you’ll see output like this:

Running Laravel Type Coverage...
Scanning for PHP files...

--------------------------------------------------------------------------------------------
  File   app/Models/ZipCode.php
--------------------------------------------------------------------------------------------
  Line   Message
--------------------------------------------------------------------------------------------
  :83    ⚠️  Method getFullZipCodeAttribute is missing type hints.
         💡 Consider adding type declarations or PHPDoc for better coverage.
  :92    ⚠️  Method getFullZipCodeInfoAttribute is missing PHPDoc and missing type hints.
         💡 Consider adding type declarations or PHPDoc for better coverage.
--------------------------------------------------------------------------------------------

Coverage: 85%

Exporting Results:

By default, the tool will export the results to laravel-type-coverage.json in your project’s root directory. You can customize the export path in the configuration file.

Example Export:

If you want to specify a custom export path:

php artisan laravel-type-coverage:run --export=/path/to/export.json

Configuration

The configuration file config/type-coverage.php contains the following options:

• paths: Array of paths to scan (default: ['app']).
• ignore: Array of paths to ignore (default: []).
• fail_under: Minimum coverage percentage required to pass (default: 80).
• export: Whether to export the results to a JSON file (default: true).
• export_path: The directory or path to export the coverage report (default: current directory).

Example:

return [
    'paths' => ['app', 'src'],
    'ignore' => ['vendor', 'storage'],
    'fail_under' => 85,
    'export' => true,
    'export_path' => 'coverage_reports/',
];
