Testing a JSON PUT request in mojolicious

I am creating test cases for my app developed using Mojolicious framework. I am testing the routes for appropriate responses for the REST calls that are made. I use JSON as a means of communication between the server and client. To test GET, POST and DELETE requests I use the following functions

GET : get_ok()
POST: post_json_ok()
DELETE: delete_ok()

but for PUT I am not able to use put_ok(). And example of my usage of put_ok() would be

my $t = Test::Mojo->new;
$t->put_ok('this/is/url/to/resource'=>{ "element" => "modified value"})->status_is(204)

I get a bad request status every time(400) and so the test fails. I use Test::Mojo for testing my application.

Additional information:

$t->put_ok('http://localhost:3000/application/instances/system/test'=>{"model" => "testing put"})->status_is(204);

This is the exact test for PUT request that is attempted.
model is a property of resource test that is being attempted to be changed to testing put and the expected status response is 204.

The mapping to the controller is done by $r->route('/application/instances/system/:id, id => qr/[A-Za-z0-9 ]+/ -> via('put') ->to(controller => 'system', action => 'update_sys');
This route calls the update_sys method in the system controller and that is how the resource is located.

Actually, after discussions with SRI on IRC, he pointed me to an example almost identical you your needs in the documentation.

# Test custom transaction
my $tx = $t->ua->build_json_tx('/user/99' => {name => 'sri'});
$tx->req->method('PUT');
$t->tx($t->ua->start($tx))
  ->status_is(200)
  ->json_is('/message' => 'User has been replaced.');

So this should work for you!

Postscript:

You might be interested to know that this discussion has brought some progress: the next release of Mojolicious (version 3.66) will now have a cleaner syntax for this purpose, the new request_ok method. The above example can then be rewritten as

my $tx = $t->ua->build_json_tx('/user/99' => {name => 'sri'});
$tx->req->method('PUT');
$t->request_ok($tx)
  ->status_is(200)
  ->json_is('/message' => 'User has been replaced.');

Can you share the definition of your route for 'this/is/url/to/resource' ? the server is returning 400, so it appears Mojo::Controller in your app does not understand what you are sending ...
