=head1 DESCRIPTION |
237
|
|
|
|
|
|
|
|
238
|
|
|
|
|
|
|
This module provides basic tools for testing a Kelp based web application. It |
239
|
|
|
|
|
|
|
is object oriented, and all methods return C<$self>, so they can be chained |
240
|
|
|
|
|
|
|
together. |
241
|
|
|
|
|
|
|
Testing is done by sending HTTP requests to an already built application and |
242
|
|
|
|
|
|
|
analyzing the response. Therefore, each test usually begins with the L</request> |
243
|
|
|
|
|
|
|
method, which takes a single L<HTTP::Request> parameter. It sends the request to |
244
|
|
|
|
|
|
|
the web app and saves the response as an L<HTTP::Response> object. |

This module sets the C<KELP_TESTING> environmental variable to a true value. |

|
|
|
|
|
The Kelp::Test object is instantiated with single attribute called C<app>. It |
257
|
|
|
|
|
|
|
is a reference to a Kelp based web app. |
258
|
|
|
|
|
|
|
|
259
|
|
|
|
|
|
|
my $myapp = MyApp->new; |
260
|
|
|
|
|
|
|
my $t = Kelp::Test->new( app => $myapp ); |
261
|
|
|
|
|
|
|
|
262
|
|
|
|
|
|
|
From this point on, all requests run with C<$t-E<gt>request> will be sent to C<$app>. |
263

=head2 res |
265
|
|
|
|
|
|
|
|
266
|
|
|
|
|
|
|
Each time C<$t-E<gt>request> is used to send a request, an HTTP::Response object is |
267
|
|
|
|
|
|
|
returned and saved in the C<res> attribute. You can use it to run tests, |
268
|
|
|
|
|
|
|
although as you will see, this module provides methods which make this a lot |
269
|
|
|
|
|
|
|
easier. It is recommended that you use the convenience methods rather than using |
270
|
|
|
|
|
|
|
C<res>. |

|
$t->request( GET '/path' ) |
273
|

276
|

277
|
|
|
|
|
|
|
An L<HTTP::Cookies> object containing the cookie jar for all tests. |

281

|

|
|
=head2 request |
282
|
|
|
|
|
|
|
|
283
|
|
|
|
|
|
|
C<request( $http_request )> |
284
|
|
|
|
|
|
|
|
285
|
|
|
|
|
|
|
Takes an L<HTTP::Request> object and sends it to the application. When the |
286
|
|
|
|
|
|
|
L<HTTP::Response> object is returned, it is initialized in the L</res> |
287
|
|
|
|
|
|
|
attribute. |
288
|
|
|
|
|
|
|
It is very convenient to use L<HTTP::Request::Common> in your test modules, so |
289
|
|
|
|
|
|
|
you can take advantage of the simplified syntax for creating an HTTP request. |
290
|
|
|
|
|
|
|
|
291
|
|
|
|
|
|
|
$t->request( POST '/api', [ user => 'jane' ] ); |
292
|
|
|
|
|
|
|
|
293
|
|
|
|
|
|
|
This method returns C<$self>, so other methods can be chained after it. |

Tests if the last response returned a status code equal or not equal to C<$code>. |

This tests for two things: If the returned C<content-type> is |
377
|
|
|
|
|
|
|
C<application-json>, and if the returned JSON structure matches the structure |
378
|
|
|
|
|
|
|
specified in C<$expected>. To compare the two structures this method uses |
379
|
|
|
|
|
|
|
C<cmp_deeply> from L<Test::Deep>, so you can use all the goodies from the |
380
|
|
|
|
|
|
|
C<SPECIAL-COMPARISONS-PROVIDED> section of the Test::Deep module. |
