probe

plugin 'Test::Mock' => (
  probe => $probe,
);

Override the probe behavior by one of the following:

share

For a "share" build.

system

For a "system" build.

die

To throw an exception in the probe hook. This will usually cause Alien::Build to try the next probe hook, if available, or to assume a "share" install.

download

plugin 'Test::Mock' => (
  download => \%fs_spec,
);

plugin 'Test::Mock' => (
  download => 1,
);

Mock out a download. The %fs_spec is a hash where the hash values are directories and the string values are files. This a spec like this:

plugin 'Test::Mock' => (
  download => {
    'foo-1.00' => {
      'README.txt' => "something to read",
      'foo.c' => "#include <stdio.h>\n",
                 "int main() {\n",
                 "  printf(\"hello world\\n\");\n",
                 "}\n",
    }
  },
);

Would generate two files in the directory 'foo-1.00', a "README.txt" and a C file named "foo.c". The default, if you provide a true non-hash value is to generate a single tarball with the name "foo-1.00.tar.gz".

extract

plugin 'Test::Mock' => (
  extract => \%fs_spec,
);

plugin 'Test::Mock' => (
  extract => 1,
);

Similar to "download" above, but for the "extract" phase.

build

plugin 'Test::Mock' => (
  build => [ \%fs_spec_build, \%fs_spec_install ],
);

plugin 'Test::Mock' => (
  build => 1,
);

gather

plugin 'Test::Mock' => (
  gather => \%runtime_prop,
);

plugin 'Test::Mock' => (
  gather => 1,
);

This adds a gather hook (for both "share" and "system") that adds the given runtime properties, or if a true non-hash value is provided, some reasonable runtime properties for testing.

check_digest

plugin 'Test::Mock' => (
  check_digest => 1,  # the default
);

This adds a check_digest hook that uses fake algorithm FAKE that hashes everything to "deadbeaf". The mock download above will set the digest for download_details so that this will pass the signature check.

plugin 'Test::Mock' => (
  check_digest => sub {
    my($build, $file, $algo, $digest) = @_;
    ...
  },
);

If you give it a code reference then you can write your own faux digest. See the check_digest hook in Alien::Build::Manual::PluginAuthor for details.
