23 This module provides test helpers for testing Dancer apps.
24
25 Be careful, the module loading order in the example above is very
26 important. Make sure to use "Dancer::Test" after importing the
27 application package otherwise your appdir will be automatically set to
28 "lib" and your test script won't be able to find views, conffiles and
29 other application content.
30
31 For all test methods, the first argument can be either an array ref of
32 the method and route, or a scalar containing the route (in which case
33 the method is assumed to be "GET"), or a Dancer::Response object.
34
35 # all 3 are equivalent
36 response_status_is [ GET => '/' ], 200, 'GET / status is ok';
37
38 response_status_is '/', 200, 'GET / status is ok';
39
40 my $resp = dancer_response GET => '/';
41 response_status_is $resp => 200, 'GET / status is ok';
42
44 route_exists([$method, $path], $test_name)
45 Asserts that the given request matches a route handler in Dancer's
46 registry.
47
48 route_exists [GET => '/'], "GET / is handled";
49
50 route_doesnt_exist([$method, $path], $test_name)
51 Asserts that the given request does not match any route handler in
52 Dancer's registry.
53
54 route_doesnt_exist [GET => '/bogus_path'], "GET /bogus_path is not handled";
55
56 response_exists([$method, $path], $test_name)
57 Deprecated - Use response_status_isnt and check for status 404.
58
59 Asserts that a response is found for the given request (note that even
60 though a route for that path might not exist, a response can be found
61 during request processing, because of filters).
62
63 response_exists [GET => '/path_that_gets_redirected_to_home'],
64 "response found for unknown path";
65
66 response_doesnt_exist([$method, $path], $test_name)
67 Deprecated - Use response_status_is and check for status 404.
68
69 Asserts that no response is found when processing the given request.
70
71 response_doesnt_exist [GET => '/unknown_path'],
72 "response not found for unknown path";
73
74 response_status_is([$method, $path], $status, $test_name)
75 Asserts that Dancer's response for the given request has a status equal
76 to the one given.
77
78 response_status_is [GET => '/'], 200, "response for GET / is 200";
79
80 response_status_isnt([$method, $path], $status, $test_name)
81 Asserts that the status of Dancer's response is not equal to the one
82 given.
83
84 response_status_isnt [GET => '/'], 404, "response for GET / is not a 404";
85
86 response_content_is([$method, $path], $expected, $test_name)
87 Asserts that the response content is equal to the $expected string.
88
89 response_content_is [GET => '/'], "Hello, World",
90 "got expected response content for GET /";
91
92 response_content_isnt([$method, $path], $not_expected, $test_name)
93 Asserts that the response content is not equal to the $not_expected
94 string.
95
96 response_content_isnt [GET => '/'], "Hello, World",
97 "got expected response content for GET /";
98
99 response_content_is_deeply([$method, $path], $expected_struct, $test_name)
100 Similar to response_content_is(), except that if response content and
101 $expected_struct are references, it does a deep comparison walking each
102 data structure to see if they are equivalent.
103
104 If the two structures are different, it will display the place where
105 they start differing.
106
107 response_content_is_deeply [GET => '/complex_struct'],
108 { foo => 42, bar => 24},
109 "got expected response structure for GET /complex_struct";
110
111 response_content_like([$method, $path], $regexp, $test_name)
112 Asserts that the response content for the given request matches the
113 regexp given.
114
115 response_content_like [GET => '/'], qr/Hello, World/,
116 "response content looks good for GET /";
117
118 response_content_unlike([$method, $path], $regexp, $test_name)
119 Asserts that the response content for the given request does not match
120 the regexp given.
121
122 response_content_unlike [GET => '/'], qr/Page not found/,
123 "response content looks good for GET /";
124
125 response_headers_are_deeply([$method, $path], $expected, $test_name)
126 Asserts that the response headers data structure equals the one given.
127
128 response_headers_are_deeply [GET => '/'], [ 'X-Powered-By' => 'Dancer 1.150' ];
129
130 response_headers_include([$method, $path], $expected, $test_name)
131 Asserts that the response headers data structure includes some of the
132 defined ones.
133
134 response_headers_include [GET => '/'], [ 'Content-Type' => 'text/plain' ];
135
136 response_redirect_location_is([$method, $path], $expected, $test_name)
137 Asserts that the location header sent with a 302 redirect is equal to
138 the $expected location.
139
140 response_redirect_location_is [GET => '/'], 'http://localhost/index.html';
141
142 response_redirect_location_like([$method, $path], $regexp, $test_name)
143 Asserts that the location header sent with a 302 redirect matches the
144 $regexp provided. Useful if the redirect location includes a query
145 string.
146
147 response_redirect_location_like [GET => '/'], qr/some_pattern/;
148
149 dancer_response($method, $path, { params => $params, body => $body, headers
150 => $headers, files => [{filename => '/path/to/file', name =>
151 'my_file'}] })
152 Returns a Dancer::Response object for the given request.
153
154 Only $method and $path are required.
155
156 $params is a hashref, $body can be a string or a hashref and $headers
157 can be an arrayref or a HTTP::Headers object, $files is an arrayref of
158 hashref, containing some files to upload.
159
160 $params always populates the query string, even for POST requests.
161 $body always populates the request body.
162
163 Currently, Dancer::Test cannot cope with both body and files passed in
164 the same call.
165
166 A good reason to use this function is for testing POST requests. Since
167 POST requests may not be idempotent, it is necessary to capture the
168 content and status in one shot. Calling the response_status_is and
169 response_content_is functions in succession would make two requests,
170 each of which could alter the state of the application and cause
171 Schrodinger's cat to die.
172
173 my $response = dancer_response POST => '/widgets';
174 is $response->{status}, 202, "response for POST /widgets is 202";
175 is $response->{content}, "Widget #1 has been scheduled for creation",
176 "response content looks good for first POST /widgets";
177
178 $response = dancer_response POST => '/widgets';
179 is $response->{status}, 202, "response for POST /widgets is 202";
180 is $response->{content}, "Widget #2 has been scheduled for creation",
181 "response content looks good for second POST /widgets";
182
183 It's possible to test file uploads:
184
185 post '/upload' => sub { return upload('image')->content };
186
187 $response = dancer_response(POST => '/upload', {files => [{name => 'image', filename => '/path/to/image.jpg'}]});
188
189 In addition, you can supply the file contents as the "data" key:
190
191 my $data = 'A test string that will pretend to be file contents.';
192 $response = dancer_response(POST => '/upload', {
193 files => [{name => 'test', filename => "filename.ext", data => $data}]
194 });
195
196 read_logs
197 my $logs = read_logs;
198
199 Returns an array ref of all log messages issued by the app since the
200 last call to "read_logs".
201
202 For example:
203
204 warning "Danger! Warning!";
205 debug "I like pie.";
206
207 is_deeply read_logs, [
208 { level => "warning", message => "Danger! Warning!" },
209 { level => "debug", message => "I like pie.", }
210 ];
211
212 error "Put out the light.";
213
214 is_deeply read_logs, [
215 { level => "error", message => "Put out the light." },
216 ];
