Fishtape

Written entirely in Fish with zero external dependencies, ensuring native integration and minimal setup for Fish users, as emphasized in the README's philosophy.

Produces standard TAP output that integrates seamlessly with CI systems and reporters, allowing for flexible reporting options as listed in the documentation.

Each test file runs in its own shell instance, preventing environment pollution and test interference, which is highlighted as a key feature for reliable testing.

Uses the @test function with Fish's built-in test operators, making assertions intuitive and expressive for developers familiar with Fish shell commands.
