30 There are a number of different situations (like testing caching code)
31 where you want to want to do a number of tests, and then verify that
32 some underlying subroutine deep within the code was called a specific
33 number of times.
34
35 This module provides a number of functions for doing testing in this
36 way in association with your normal Test::More (or similar) test
37 scripts.
38
40 In the nature of test modules, all functions are exported by default.
41
42 sub_track $subname
43 The "sub_track" function creates a new call tracker for a named
44 function.
45
46 The sub to track must be provided by name, references to the function
47 itself are insufficient.
48
49 Returns true if added, or dies on error.
50
51 sub_calls $subname, $expected_calls [, $message ]
52 The "sub_calls" function is the primary (and only) testing function
53 provided by "Test::SubCalls". A single call will represent one test in
54 your plan.
55
56 It takes the subroutine name as originally provided to "sub_track", the
57 expected number of times the subroutine should have been called, and an
58 optional test message.
59
60 If no message is provided, a default message will be provided for you.
61
62 Test is ok if the number of times the sub has been called matches the
63 expected number, or not ok if not.
64
65 sub_reset $subname
66 To prevent repeat users from having to take before and after counts
67 when they start testing from after zero, the "sub_reset" function has
68 been provided to reset a sub call counter to zero.
69
70 Returns true or dies if the sub name is invalid or not currently
71 tracked.
72
73 sub_reset_all
74 Provided mainly as a convenience, the "sub_reset_all" function will
75 reset all the counters currently defined.
76
77 Returns true.
