-  /* Checks that two packages produce the exact same build instructions.
-
-     This can be used to make sure that a certain difference of configuration,
-     such as the presence of an overlay does not cause a cache miss.
-
-     When the derivations are equal, the return value is an empty file.
-     Otherwise, the build log explains the difference via `nix-diff`.
-
-     Example:
-
-         testEqualDerivation
-           "The hello package must stay the same when enabling checks."
-           hello
-           (hello.overrideAttrs(o: { doCheck = true; }))

-  /* Checks the command output contains the specified version
-
-     Although simplistic, this test assures that the main program
-     can run. While there's no substitute for a real test case,
-     it does catch dynamic linking errors and such. It also provides
-     some protection against accidentally building the wrong version,
-     for example when using an 'old' hash in a fixed-output derivation.
-
-     Examples:
-
-       passthru.tests.version = testVersion { package = hello; };
-
-       passthru.tests.version = testVersion {
-         package = seaweedfs;
-         command = "weed version";
-       };
-
-       passthru.tests.version = testVersion {
-         package = key;
-         command = "KeY --help";
-         # Wrong '2.5' version in the code. Drop on next version.
-         version = "2.5";
-       };
