# Testers {#chap-testers}
This chapter describes several testing builders which are available in the testers namespace.
+## `hasPkgConfigModule` {#tester-hasPkgConfigModule}
+
+Checks whether a package exposes a certain `pkg-config` module.
+
+Example:
+
+```nix
+passthru.tests.pkg-config = testers.hasPkgConfigModule {
+ package = finalAttrs.finalPackage;
+ moduleName = "libfoo";
+}
+```
+
## `testVersion` {#tester-testVersion}
Checks the command output contains the specified version

+# pkg-config {#sec-pkg-config}
+
+*pkg-config* is a unified interface for declaring and querying built C/C++ libraries.
+
+Nixpkgs provides a couple of facilities for working with this tool.
+
+ - A [setup hook](#setup-hook-pkg-config) bundled with in the `pkg-config` package, to bring a derivation's declared build inputs into the environment.
+ - The [`validatePkgConfig` setup hook](https://nixos.org/manual/nixpkgs/stable/#validatepkgconfig), for packages that provide pkg-config modules.
+ - The `defaultPkgConfigPackages` package set: a set of aliases, named after the modules they provide. This is meant to be used by language-to-nix integrations. Hand-written packages should use the normal Nixpkgs attribute name instead.
