161
|
|
|
|
|
|
|
|
162
|
|
|
|
|
|
|
I<This model is experimental, so take care!> The current version has different |
163
|
|
|
|
|
|
|
behaviour for C<test_daia> and C<test_daia_psgi>, that might get fixed. |
164
|
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
This module exports two methods for testing L<DAIA> servers. You must provide a |
166
|
|
|
|
|
|
|
DAIA server as code reference or as instance of L<Plack::App::DAIA> and a list |
167
|
|
|
|
|
|
|
of request identifiers and testing code. The testing code is passed a valid |
168
|
|
|
|
|
|
|
L<DAIA::Response> object on success (C<$_> is also set to this response). |
169

=head2 test_daia ( $app, $id1 => sub { }, $id2 => ... ) |
173
|
|
|
|
|
|
|
|
174
|
|
|
|
|
|
|
Calls a DAIA server C<$app>'s request method with one or more identifiers, |
175
|
|
|
|
|
|
|
each given a test function. |
176
|

|
|
|
|
|
|
=head2 test_daia_psgi ( $app, $id => sub { }, $id => ... ) |
178
|
|
|
|
|
|
|
|
179
|
|
|
|
|
|
|
Calls a DAIA server C<$app> as L<PSGI> application with one or more |
180
|
|
|
|
|
|
|
identifiers, each given a test function. |
181

183
|
|
|
|
|
|
|
|
184
|
|
|
|
|
|
|
Returns an instance of L<Plack::App::DAIA> or undef. Code references or URLs |
185
|
|
|
|
|
|
|
are wrapped. For wrapped URLs C<$@> is set on failure. This method may be removed |
186
|
|
|
|
|
|
|
to be used internally only! |
