# Testers {#chap-testers}
|
||||
This chapter describes several testing builders which are available in the <literal>testers</literal> 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
