# Tests _for the testers_

    cd nixpkgs
    nix-build -A tests.testers

Tests generally derive their own correctness from simplicity, which in the
case of testers (themselves functions) does not always work out.
Hence the need for tests that test the testers.

Title: Testing the Testers in Nixpkgs

Summary

This section discusses the need for tests that specifically test the 'testers' within the Nixpkgs framework. Because testers are functions, their correctness isn't always self-evident through simplicity, thus necessitating dedicated tests to ensure they function as expected.
