6 WWW::Search::Test - utilities to aid in testing WWW::Search backends
7
9 $oTest = new WWW::Search::Test('HotBot,Yahoo,Excite');
10 $oTest->test('HotBot', 'Kingpin', 'one', $sQuery, $TEST_RANGE, 1, 10);

13 See file test.pl in the WWW-Search-HotBot distribution for a detailed
14 "real-world" example.
15
17 find_websearch
18 Returns the full path of an executable WebSearch program, or undef if
19 none can be found.
20 new
22 Create a new WWW::Search::Test object. All arguments are strings,
23 names of backends that this object will be able to test. If no
24 arguments are given, will be able to test all backends.
25 mode
27 Set / get the test mode of this object. If an argument is given, sets
28 the mode to that value. Returns the current (or newly set) value.
29 There are three test modes available. They are:
31 $MODE_INTERNAL: parse URLs out of saved pages (as a sanity check or regression test);
33 $MODE_EXTERNAL: send the query to the search engine "live", parse the results, and compare them to the previously saved results;
34 and
35 $MODE_UPDATE: send the query to the search engine "live", parse the results, and save them for future testing.
36 relevant_test
38 Given the name of a backend, returns true if this Test object is able
39 to test that backend.
40 eval_test
42 Given the name of a backend, grabs the $TEST_CASES variable from that
43 backend and evaluates it.
44 test
46 Run test(s) for a backend. Arguments are, in order: name of a backend
47 to test (string, required); name of backend maintainer (string, if
48 undef $backend::MAINTAINER will be used); filename for results
49 storage/comparison (string, required); query to be sent to backend
50 (string, required); test method (required, one of the following).
51 Several test methods are possible:
53 $TEST_EXACTLY: list of URLs must match exactly (line for line, in order);
55 $TEST_BY_COUNTING: test passes if number of resulting URLs is equal;
56 $TEST_GREATER_THAN: test passes if we get more than N result URLs;
57 and
58 $TEST_RANGE: like $TEST_GREATER_THAN but constrained on both ends.
59 no_test
61 Prints a message stating that this backend does not have a test suite.
62 Takes two arguments, the backend name and the name of the maintainer.
63 not_working
65 Prints a message stating that this backend is known to be broken.
66 Takes two arguments, the backend name and the name of the maintainer.
67 not_working_with_tests
69 Prints a message stating that this backend is known to be broken even
70 though it has a test suite. Takes two arguments, the backend name and
71 the name of the maintainer.
72 not_working_and_abandoned
74 Prints a message stating that this backend is known to be broken and is
75 not being actively maintained. Takes two arguments, the backend name
76 and the name of the maintainer.
77 reset_error_count
79 Reset the counter of errors to zero. You probably want to call this
80 before each call to test() or eval_test().
81 wc_l (private, not a method)
83 Given a filename, count the number of lines of text contained within
84 the file. (I.e. simulate running UNIX command "wc -l" on a file)
85 diff (private, not a method)
87 Given two files, returns TRUE if contents are line-by-line different,
88 or FALSE if contents are line-by-line same. (I.e. like the UNIX
89 command diff, but just reports true or false)
90 Shortcuts for running backend tests
92 WWW::Search::Test keeps its own count of test numbers, so if you want
93 to mix-and-match these functions with your own tests, use the
94 $WWW::Search::Test::iTest counter.
95 new_engine
97 One argument: the name of a backend suitable to be passed to
98 WWW::Search::new(). Prints 'ok' or 'not ok' and the test number.
99 Creates a WWW::Search object internally, to be used for all subsequent
100 calls to run_test and run_gui_test (see below).
101 tm_new_engine
103 Same as new_engine(), but uses Test::More instead of just printing
104 'ok'.
105 run_test
107 Three arguments: a query string, NOT escaped; a minimum number of
108 expected results; and a maximum number of expected results. Optional
109 fourth argument: integer value to be used as the search_debug.
110 Optional fifth argument: send any true value to dump the search
111 results. Optional sixth argument: reference to hash of search options
112 (see backend documentation). Optional seventh argument: send any true
113 value to NOT escape the query string.
114 If the minimum is undef, assumes zero. If the maximum is undef, does
116 not check.
117 Prints 'ok' or 'not ok' and the test number.
119 run_gui_test
121 Same as run_test(), but calls gui_query() instead of native_query().
122 tm_run_test
124 Same as run_test(), but uses Test::More rather than just printing 'ok'.
125 Note: If you use this function inside a TODO block, you must set global
127 variable $TODO rather than a local $TODO, and you must set the global
128 $TODO back to empty-string (or undef) at the end of your TODO block.
129 For example:
130 TODO:
132 {
133 $TODO = 'I have not fixed this yet';
134 tm_run_test(...);
135 $TODO = '';
136 } # end of TODO block
137 tm_run_test_no_approx
139 Same as tm_run_test, but does NOT check the approximate_result_count.
140 count_results
142 Run a query, and return the actual (not approximate) number of hits.
143 Required first argument determines which backend query method to call:
144 'gui' to call gui_query(), anything else to call native_query().
145 Remaining arguments are same as all the run_test() arguments.
146 skip_test
148 You can call this function instead of run_test() or run_gui_test() if
149 the current test must be skipped for any reason.
150 test_most_results
152 Given an arrayref of things to test, runs all those things against all
153 the results of the most-recently executed test search.
