Phpunit Printer Laravel Package

Getting Started

Install via Composer: composer require --dev tflori/phpunit-printer. Configure PHPUnit to use one of its custom printers by adding a <printer> element in phpunit.xml—for example: <printer class="Tflori\PHPUnitPrinter\DebugPrinter" />. Start with the DebugPrinter to see detailed test execution flow, including method calls, assertions, and now assertion counts (new in v2.1.0). The ProgressPrinter also now conditionally renders colored status icons only when TTY output is detected, improving CI compatibility.

Implementation Patterns

Developers integrate this package to customize test output formatting—e.g., using CompactPrinter for CI environments where minimal noise is desired, or ProgressPrinter to show real-time progress with assertion counts (new in v2.1.0). Printers are stateful and implement PHPUnit\TextUI\ResultPrinter, so they can be extended or reused across projects. A common pattern is to swap printers dynamically via environment variables (e.g., PHPUnit_Printer=compact), allowing local development with verbose feedback while keeping CI output clean. The new assertion count feature is particularly useful for tracking test granularity without cluttering output.

Gotchas and Tips

• Printer class names must be fully qualified and match PSR-4 autoloading; misconfigured phpunit.xml paths cause silent "class not found" errors.
• The ProgressPrinter now conditionally renders colored status icons only when TTY output is detected (v2.1.0), reducing CI output issues, but verify behavior in non-TTY environments if customizing further.
• The package’s minimal stars and 2022 release date suggest limited active maintenance; verify compatibility with your PHPUnit version (tested up to PHPUnit 9.x, may fail on 10+).
• For custom logic, extend the base ResultPrinter class instead of relying solely on included printers—this ensures future-proofing if built-in printers are deprecated.
• Assertion counts (new in v2.1.0) are additive and may impact performance in large test suites; test in your environment to confirm acceptable overhead.
