tdd.nvim is a Neovim plugin designed to streamline test-driven development for PHP projects. It allows you to quickly jump between a PHP class and its corresponding PHPUnit test, and will create the test file if it doesn't exist.

NOTE: This plugin is still under active development. In future versions, it is expected to handle namespaces and file paths more robustly.

• Detects matching test files based on PSR-4 mappings in composer.json
• Prompts to open an existing test in a vertical split
• Creates a new PHPUnit test class with the correct namespace and path
• Parses both autoload and autoload-dev sections from composer.json
• Automatically finds the project root

Using Lazy.nvim:

{
  "zkucekovic/tdd.nvim",
  config = function()
    require("tdd").setup()
  end,
}

Open any PHP class file and run the following command:

:GetTest

If a matching test file exists, the plugin will prompt you to open it in a vertical split. If it doesn't exist, it will offer to create one using a PHPUnit skeleton. The plugin uses the PSR-4 autoload mappings in your composer.json file to determine the correct file path and namespace.

Given a source file:

src/Article/src/Repository/Article.php

And the following composer.json mapping:

"autoload": {
  "psr-4": {
    "Content\\Article\\": "src/Article/src"
  }
},
"autoload-dev": {
  "psr-4": {
    "Test\\Content\\Article\\": "src/Article/tests/src"
  }
}

tdd.nvim will create or open:

src/Article/tests/src/Repository/ArticleTest.php

With the following namespace:

namespace Test\Content\Article\Repository;

Contributions are welcome. Please keep the code simple, modular, and testable. The plugin is in early development, so unit tests are not mandatory yet, but writing clean and reusable modules is encouraged.
