Testing Language and Location APIs

Testing with the Location API
To write a test for a location-aware Instant Answer, you'll need to pass the test function an extra parameter - a DDG::Request object, with the location specified. To do this, you'll need to use DDG::Test::Location and use DDG::Request. Here is a working annotated example excerpted from the Spice::Snow Instant Answer test file. The same process should be used for Goodies.
Note that only a small set of locations are available to be simulated for testing. They are defined in DDG::Test::Location.pm.
#!/usr/bin/env perl
​
use strict;
use warnings;
use Test::More;
use DDG::Test::Spice;
​
# These two modules are only necessary when testing with the Location API.
use DDG::Test::Location;
use DDG::Request;
​
ddg_spice_test(
    [qw( DDG::Spice::Snow )],
    # This optional argument to ddg_spice_test is a DDG::Request object.
    # The object constructor takes two arguments of its own:
    # the query (usually specified in the test_zci),
    # and a location object - created by test_location (with a country code).
    DDG::Request->new(
        query_raw => "is it snowing?",
        location => test_location("de")
    ) => test_spice(
        '/js/spice/snow/'
        .'M%C3%B6nchengladbach%2C%20%20Nordrhein-Westfalen%2C%20%20Germany',
        call_type => 'include',
        caller => 'DDG::Spice::Snow',
    ),
    # The DDG::Request is used in place of a query string, and isn't necessary
    # to be used with every test passed to ddg_spice_test.
    'is it snowing in new york?' => test_spice(
        '/js/spice/snow/new%20york',
        call_type => 'include',
        caller => 'DDG::Spice::Snow',
    )
);
​
done_testing;
Testing with the Language API
To write a test for a locale-aware Instant Answer, you'll need to pass the test function an extra parameter - a DDG::Request object, with the location specified. To do this, you'll need to use DDG::Test::Language and use DDG::Request. Here is a quick annotated example testing the language detect feature of the Translate Instant Answer:
#!/usr/bin/env perl
​
use strict;
use warnings;
use Test::More;
use DDG::Test::Spice;
​
# These two modules are only necessary when testing with the Language API.
use DDG::Test::Language;
use DDG::Request;
​
ddg_spice_test(
    ["DDG::Spice::Translate::Detect"],
    # This optional argument to ddg_spice_test is a DDG::Request object.
    # The two arguments we pass to the constructor are:
    # the query we're testing against
    # language object, created by calling test_language with a country code
​
    # Note that the only supported values for test_language are:
    # "us" (US English), "de" (German) and "my" (Malay)
    DDG::Request->new(
        query_raw => "translate good",
        language => test_language("de"),
    ), test_spice(
        '/js/spice/translate/detect/good/de',
        caller => "DDG::Spice::Translate::Detect"
    )
);
​
done_testing;
