Testing Hello World of Dancer
The fastest and cheapest way to do this to write tests. Unit-, integration-, acceptance tests, name them as you like, the important part is that they verify that the code works (and fails) as expected.
As this is such an integral part of writing code, we won't delay writing tests to the end of the project. We jump in right now.
Next to our app.psgi we create a file called test.t with the following content.
use strict; use warnings; use Test::More; use Plack::Test; use Plack::Util; use HTTP::Request::Common; my $app = Plack::Util::load_psgi './app.psgi'; my $test = Plack::Test->create($app); my $res = $test->request(GET '/'); is $res->status_line, '200 OK', 'Status'; is $res->content, 'Hello World!', 'Content'; done_testing();
prove -v test.t
test.t .. ok 1 - Status ok 2 - Content 1..2 ok All tests successful. Files=1, Tests=2, 0 wallclock secs ( 0.02 usr 0.01 sys + 0.28 cusr 0.01 csys = 0.32 CPU) Result: PASS
