PHP_Testability

Analyses and produces a report with testability issues of a php codebase.

Installation

PHP_Testability requires at least PHP 7.0 to run.

Composer

Add edsonmedina/php_testability as a dependency to your project's composer.json file if you use Composer to manage the dependencies of your project.

{
    "require-dev": {
        "edsonmedina/php_testability": "dev-master"
    }
}

And run composer update.

Or alternatively, just run:

composer require edsonmedina/php_testability "dev-master"

Usage

Analyse the current directory and generate an HTML report into report/

vendor/bin/testability . -o report

Exclude some directories

vendor/bin/testability . -x vendor,tmp,upload,config -o report

Check all the available options.

vendor/bin/testability --help

Results

Open report/index.html on your browser. You shoule see something like this:

If you click on a file with issues, it'll show you a code browser and will highlight the lines with issues.

These are issues that hinder testability, such as:

references to global variables, super globals, etc
calls to functions that can't be mocked (like static methods or global functions)
new instances of objects (tight coupling - can't be mocked/injected)
...and much more

Kudos to the brilliant PHP-Parser (by nikic) on which PHP_Testability relies heavily.
