|
|
|
Run a DAIA test suite from a string or stream (GLOB or L<IO::File>). A DAIA |
145
|
|
|
|
|
|
|
test suite lists servers, identifiers, and DAIA/JSON response fragments to test |
146
|
|
|
|
|
|
|
DAIA servers. The command line client L<provedaia> is included in this |
147
|
|
|
|
|
|
|
distribution for convenience. |
148
|
|
|
|
|
|
|
|
149
|
|
|
|
|
|
|
Additional option supported so far are C<server> and C<ids>. The former is |
150
|
|
|
|
|
|
|
equivalent to an inital C<server=...> statement in you test suite and the |
151
|
|
|
|
|
|
|
latter is equivalent to an initial list of identifiers in you test suite. |
152
|
|
|
|
|
|
|
|
153
|
|
|
|
|
|
|
If the option C<end> is set, all lines before C<__END__> are ignored in the |
154
|
|
|
|
|
|
|
test suite script. The option C<verbose> adds more diagnostic messages. |
155

=head1 TEST SUITE FORMAT |
157
|
|
|
|
|
|
|
|
158
|
|
|
|
|
|
|
A test suite is defined in a text-based format that is parsed line by line. |
159
|
|
|
|
|
|
|
Empty lines are ignored. There are four kinds of statements: |
160
|
|
|
|
|
|
|
|
161
|
|
|
|
|
|
|
=over 4 |
162
|
|
|
|
|
|
|
|
163
|
|
|
|
|
|
|
=item comments |
164
|
|
|
|
|
|
|
|
165
|
|
|
|
|
|
|
All lines starting with C<#> are treated as comments. |
166
|
|
|
|
|
|
|
|
167
|
|
|
|
|
|
|
=item responses |
168
|
|
|
|
|
|
|
|
169
|
|
|
|
|
|
|
All lines starting with C<{>} begin a response (fragment) in JSON format. |
170
|
|
|
|
|
|
|
Following lines are treated as part of the JSON structure until an empty line |
171
|
|
|
|
|
|
|
or the end of the file. References to assigned variables, such as C<$server>, |
172
|
|
|
|
|
|
|
are replaced, including the special variable C<$id> for the current identifier. |
173
|
|
|
|
|
|
|
|
174
|
|
|
|
|
|
|
=item assignements |
175
|
|
|
|
|
|
|
|
176
|
|
|
|
|
|
|
All lines of the form C<key=value>, where C<key> contains of lowercase letters |
177
|
|
|
|
|
|
|
a-z only, are treated as variable assignements. In particular, the variable |
178
|
|
|
|
|
|
|
C<server> is used to set a server (an URL or a PSGI script) and the variable |
179
|
|
|
|
|
|
|
C<id> can be used to reset the list of identifiers. |
180
|
|
|
|
|
|
|
|
181
|
|
|
|
|
|
|
=item identifiers |
182
|
|
|
|
|
|
|
|
183
|
|
|
|
|
|
|
All other non-empty lines are treated as identifiers. Identifiers are not |
184
|
|
|
|
|
|
|
expected to be URI-encoded. |
185
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
188
|
|
|
|
|
|
|
Every time a response has been read, all preceding identifiers are used to |
189
|
|
|
|
|
|
|
query the current server and the response is compared with |
190
|
|
|
|
|
|
|
L<Test::JSON::Entails>. Here is an example of a test suite: |
