DESCRIPTION

53       This module provides HTML output formatting for TAP::Harness (a
54       replacement for Test::Harness.  It is largely based on ideas from
55       TAP::Test::HTMLMatrix (which was built on Test::Harness and thus had a
56       few limitations - hence this module).  For sample output, see:
57
58       <http://www.spurkis.org/TAP-Formatter-HTML/test-output.html>
59
60       This module is targeted at all users of automated test suites.  It's
61       meant to make reading test results easier, giving you a visual summary
62       of your test suite and letting you drill down into individual failures
63       (which will hopefully make testing more likely to happen at your
64       organization ;-).
65
66       The design goals are:
67
68       ·   easy to use
69
70           Once you've got your test report, it should be obvious how to use
71           it.
72
73       ·   helpful
74
75           It should be helpful by pointing out where & why your test suite is
76           breaking.  If you've written your tests well, it should give you
77           enough info to start tracking down the issue.
78
79       ·   easy to install
80
81           Eg: should be a clean install from CPAN, and you shouldn't need to
82           modify your existing test suite to get up & running, though you
83           will need to stop using Test::Harness unfortunately.
84
85       ·   work out of the box
86
87           You shouldn't need to do any custom-coding to get it working - the
88           default configuration & templates should be enough to get started
89           with.  Once installed it should be a matter of running:
90
91            % prove -m -Q --formatter=TAP::Formatter::HTML >output.html
92
93           From your project's home dir, and opening the resulting file.
94
95       ·   easy to configure
96
97           You should be able to configure & customize it to suit your needs.
98           As such, css, javascript and templates are all configurable.

METHODS

101   CONSTRUCTOR
102       new
103
104         my $fmt = $class->new({ %args });
105
106   ACCESSORS
107       All chaining accessors:
108
109       verbosity
110
111         $fmt->verbosity( [ $v ] )
112
113       Verbosity level, as defined in "new" in TAP::Harness:
114
115            1   verbose        Print individual test results (and more) to STDOUT.
116            0   normal
117           -1   quiet          Suppress some test output (eg: test failures).
118           -2   really quiet   Suppress everything to STDOUT but the HTML report.
119           -3   silent         Suppress all output to STDOUT, including the HTML report.
120
121       Note that the report is also available via "html".  You can also
122       provide a custom "output_fh" (aka "output_file") that will be used
123       instead of "stdout", even if silent is on.
124
125       stdout
126
127         $fmt->stdout( [ \*FH ] );
128
129       An IO::Handle filehandle for catching standard output.  Defaults to
130       "STDOUT".
131
132       output_fh
133
134         $fmt->output_fh( [ \*FH ] );
135
136       An IO::Handle filehandle for printing the HTML report to.  Defaults to
137       the same object as "stdout".
138
139       Note: If "verbosity" is set to "silent", printing to "output_fh" will
140       still occur.  (that is, assuming you've opened a different file, not
141       "STDOUT").
142
143       output_file
144
145         $fmt->output_file( $file_name )
146
147       Not strictly an accessor - this is a shortcut for setting "output_fh",
148       equivalent to:
149
150         $fmt->output_fh( IO::File->new( $file_name, 'w' ) );
151
152       You can set this with the "TAP_FORMATTER_HTML_OUTFILE=/path/to/file"
153       environment variable
154
155       escape_output
156
157         $fmt->escape_output( [ $boolean ] );
158
159       If set, all output to "stdout" is escaped.  This is probably only
160       useful if you're testing the formatter.  Defaults to 0.
161
162       html
163
164         $fmt->html( [ \$html ] );
165
166       This is a reference to the scalar containing the html generated on the
167       last test run.  Useful if you have "verbosity" set to "silent", and
168       have not provided a custom "output_fh" to write the report to.
169
170       tests
171
172         $fmt->tests( [ \@test_files ] )
173
174       A list of test files we're running, set by TAP::Parser.
175
176       session_class
177
178         $fmt->session_class( [ $class ] )
179
180       Class to use for TAP::Parser test sessions.  You probably won't need to
181       use this unless you're hacking or sub-classing the formatter.  Defaults
182       to TAP::Formatter::HTML::Session.
183
184       sessions
185
186         $fmt->sessions( [ \@sessions ] )
187
188       Test sessions added by TAP::Parser.  You probably won't need to use
189       this unless you're hacking or sub-classing the formatter.
190
191       template_processor
192
193         $fmt->template_processor( [ $processor ] )
194
195       The template processor to use.  Defaults to a TT2 Template processor
196       with the following config:
197
198         COMPILE_DIR  => catdir( tempdir(), 'TAP-Formatter-HTML' ),
199         COMPILE_EXT  => '.ttc',
200         INCLUDE_PATH => parent directory TAP::Formatter::HTML was loaded from
201
202       Note: INCLUDE_PATH used to be set to: "join(':', @INC)" but this was
203       causing issues on systems with > 64 dirs in @INC.  See RT #74364 for
204       details.
205
206       template
207
208         $fmt->template( [ $file_name ] )
209
210       The template file to load.  Defaults to
211       "TAP/Formatter/HTML/default_report.tt2".
212
213       You can set this with the "TAP_FORMATTER_HTML_TEMPLATE=/path/to.tt"
214       environment variable.
215
216       css_uris
217
218         $fmt->css_uris( [ \@uris ] )
219
220       A list of URIs (or strings) to include as external stylesheets in
221       <style> tags in the head of the document.  Defaults to:
222
223         ['file:TAP/Formatter/HTML/default_report.css'];
224
225       You can set this with the
226       "TAP_FORMATTER_HTML_CSS_URIS=/path/to.css:/another/path.css"
227       environment variable.
228
229       If you're using Win32, please see "WIN32 URIS".
230
231       js_uris
232
233         $fmt->js_uris( [ \@uris ] )
234
235       A list of URIs (or strings) to include as external stylesheets in
236       <script> tags in the head of the document.  Defaults to:
237
238         ['file:TAP/Formatter/HTML/jquery-1.2.6.pack.js'];
239
240       You can set this with the
241       "TAP_FORMATTER_HTML_JS_URIS=/path/to.js:/another/path.js" environment
242       variable.
243
244       If you're using Win32, please see "WIN32 URIS".
245
246       inline_css
247
248         $fmt->inline_css( [ $css ] )
249
250       If set, the formatter will include the CSS code in a <style> tag in the
251       head of the document.
252
253       inline_js
254
255         $fmt->inline_js( [ $javascript ] )
256
257       If set, the formatter will include the JavaScript code in a <script>
258       tag in the head of the document.
259
260       minify
261
262         $fmt->minify( [ $boolean ] )
263
264       If set, the formatter will attempt to reduce the size of the generated
265       report, they can get pretty big if you're not careful!  Defaults to 1
266       (true).
267
268       Note: This currently just means... remove tabs at start of a line.  It
269       may be extended in the future.
270
271       abs_file_paths
272
273         $fmt->abs_file_paths( [ $ boolean ] )
274
275       If set, the formatter will attempt to convert any relative file JS &
276       css URI's listed in "css_uris" & "js_uris" to absolute paths.  This is
277       handy if you'll be sending moving the HTML output around on your
278       harddisk, (but not so handy if you move it to another machine - see
279       "force_inline_css").  Defaults to 1.
280
281       force_inline_css
282
283         $fmt->force_inline_css( [ $boolean ] )
284
285       If set, the formatter will attempt to slurp in any file css URI's
286       listed in "css_uris", and append them to "inline_css".  This is handy
287       if you'll be sending the output around - that way you don't have to
288       send a CSS file too.  Defaults to 1.
289
290       You can set this with the "TAP_FORMATTER_HTML_FORCE_INLINE_CSS=0|1"
291       environment variable.
292
293       force_inline_js( [ $boolean ] )
294
295       If set, the formatter will attempt to slurp in any file javascript
296       URI's listed in "js_uris", and append them to "inline_js".  This is
297       handy if you'll be sending the output around - that way you don't have
298       to send javascript files too.
299
300       Note that including jquery inline doesn't work with some browsers,
301       haven't investigated why.  Defaults to 0.
302
303       You can set this with the "TAP_FORMATTER_HTML_FORCE_INLINE_JS=0|1"
304       environment variable.
305
306       color
307
308       This method is for "TAP::Harness" API compatibility only.  It does
309       nothing.
310
311   API METHODS
312       summary
313
314         $html = $fmt->summary( $aggregator )
315
316       "summary" produces a summary report after all tests are run.
317       $aggregator should be a TAP::Parser::Aggregator.
318
319       This calls:
320
321         $fmt->template_processor->process( $params )
322
323       Where $params is a data structure containing:
324
325         report      => %test_report
326         js_uris     => @js_uris
327         css_uris    => @js_uris
328         inline_js   => $inline_js
329         inline_css  => $inline_css
330         formatter   => %formatter_info
331
332       The "report" is the most complicated data structure, and will sooner or
333       later be documented in "CUSTOMIZING".
334

CUSTOMIZING

336       This section is not yet written.  Please look through the code if you
337       want to customize the templates, or sub-class.
338
339       You can use environment variables to customize the behaviour of TFH:
340
341         TAP_FORMATTER_HTML_OUTFILE=/path/to/file
342         TAP_FORMATTER_HTML_FORCE_INLINE_CSS=0|1
343         TAP_FORMATTER_HTML_FORCE_INLINE_JS=0|1
344         TAP_FORMATTER_HTML_CSS_URIS=/path/to.css:/another/path.css
345         TAP_FORMATTER_HTML_JS_URIS=/path/to.js:/another/path.js
346         TAP_FORMATTER_HTML_TEMPLATE=/path/to.tt
347
348       This should save you from having to write custom code for simple cases.
349

WIN32 URIS

351       This module tries to do the right thing when fed Win32 File paths as
352       File URIs to both "css_uris" and "js_uris", eg:
353
354         C:\some\path
355         file:///C:\some\path
356
357       While I could lecture you what a valid file URI is and point you at:
358
359       http://blogs.msdn.com/ie/archive/2006/12/06/file-uris-in-windows.aspx
360
361       Which basically says the above are invalid URIs, and you should use:
362
363         file:///C:/some/path
364         # ie: no backslashes
365
366       I also realize it's convenient to chuck in a Win32 file path, as you
367       can on Unix.  So if you're running under Win32, "TAP::Formatter::HTML"
368       will look for a signature 'X:\', '\' or 'file:' at the start of each
369       URI to see if you are referring to a file or another type of URI.
370
371       Note that you must use '"file:///C:\blah"' with 3 slashes otherwie
372       '"C:"' will become your host, which is probably not what you want.  See
373       URI::file for more details.
374
375       I realize this is a pretty basic algorithm, but it should handle most
376       cases.  If it doesn't work for you, you can always construct a valid
377       File URI instead.
