NUnit vs PHPUnit

NUnit is a unit-testing framework for .NET languages, with supported languages listed as C#, VB.NET, F#, and C++. NUnit 3 and later releases use the MIT license, which permits free use in commercial and noncommercial applications and libraries. NUnit 5 adds attributes for declaring dependencies between tests and fixtures. Its Repeat feature can set a required pass percentage from 1 to 100 and optionally stop once the outcome is determined. NUnit 5 ships builds targeting net462, net8.0, and net10.0. Installation options include project templates for Visual Studio, Visual Studio Code, and Rider, along with the dotnet new nunit command; release packages are available through NuGet and GitHub. The Visual Studio template references the NUnit Test Adapter, NUnit Analyzer, Microsoft Test SDK, and coverlet code coverage package. Documentation describes automated runs on clean machines, including Azure DevOps and GitHub Actions build agents. The project is supported by the .NET Foundation and maintained by a core team and community contributors.

PHPUnit is a free testing framework for PHP, with a command-line runner for running tests and selecting test suites. It covers assertions for return values, exceptions, side effects, output, files, JSON, XML, and error-log output. Tests can be organized through filesystem structure or XML configuration and can use data providers, dependencies, stubs, and mock objects. The framework documents code coverage reports in HTML and JSONL formats, plus JUnit and TeamCity logging configuration. For tests that fail intermittently, PHPUnit supports repeating and retrying runs through attributes and command-line options. Installation is available as a PHAR or as a Composer development dependency. PHPUnit 13 is the current stable major version and requires PHP 8.4 or later. Bug-fix support for that version runs through February 4, 2028; its end-of-life date is undetermined. Documentation is available for versions 8.5 through 13.4. PHPUnit supports Linux, macOS, Windows, and self-hosted use.
