6 Test::Stream::Plugin::Subtest - Tools for writing subtests
7
9 This package exports subs that let you write subtests.
10
11 There are 2 types of subtests, buffered and streamed. Streamed subtests
12 mimick subtest from Test::More in that they render all events as soon
13 as they are produced. Buffered subtests wait until the subtest
14 completes before rendering any results.
15
16 The main difference is that streamed subtests are unreadable when
17 combined with concurrency. Buffered subtests look fine with any number
18 of concurrent threads and processes.
19
21 This distribution is deprecated in favor of Test2, Test2::Suite, and
22 Test2::Workflow.
23
24 See Test::Stream::Manual::ToTest2 for a conversion guide.
25
27 use Test::Stream qw/Subtest/;
28
29 subtest foo => sub {
30 ...
31 };
32
33 STREAMED
34 The default option is 'buffered', use this if you want streamed, the
35 way Test::Builder does it.
36
37 # You can use either of the next 2 lines, they are both equivilent
38 use Test::Stream Subtest => ['streamed'];
39 use Test::Stream::Plugin::Subtest qw/streamed/;
40
41 subtest my_test => sub {
42 ok(1, "subtest event A");
43 ok(1, "subtest event B");
44 };
45
46 This will produce output like this:
47
48 # Subtest: my_test
49 ok 1 - subtest event A
50 ok 2 - subtest event B
51 1..2
52 ok 1 - Subtest: my_test
53
54 BUFFERED
55 # You can use either of the next 2 lines, they are both equivilent
56 use Test::Stream Subtest => ['buffered'];
57 use Test::Stream::Plugin::Subtest qw/buffered/;
58
59 subtest my_test => sub {
60 ok(1, "subtest event A");
61 ok(1, "subtest event B");
62 };
63
64 This will produce output like this:
65
66 ok 1 - my_test {
67 ok 1 - subtest event A
68 ok 2 - subtest event B
69 1..2
70 }
71
72 BOTH
73 use Test::Stream::Plugin::Subtest qw/subtest_streamed subtest_buffered/;
74
75 subtest_streamed my_streamed_test => sub {
76 ok(1, "subtest event A");
77 ok(1, "subtest event B");
78 };
79
80 subtest_buffered my_buffered_test => sub {
81 ok(1, "subtest event A");
82 ok(1, "subtest event B");
83 };
84
85 This will produce the following output:
86
87 # Subtest: my_test
88 ok 1 - subtest event A
89 ok 2 - subtest event B
90 1..2
91 ok 1 - Subtest: my_test
92
93 ok 2 - my_test {
94 ok 1 - subtest event A
95 ok 2 - subtest event B
96 1..2
97 }
98
100 You can use "bail_out" or "skip_all" in a subtest, but not in a BEGIN
101 block or use statement. This is due to the way flow control works
102 within a begin block. This is not normally an issue, but can happen in
103 rare conditions using eval, or script files as subtests.
104
106 subtest_streamed $name => $sub
107 subtest_streamed($name, $sub, @args)
108 Run subtest coderef, stream events as they happen.
109
110 subtest_buffered $name => $sub
111 subtest_buffered($name, $sub, @args)
112 Run subtest coderef, render events all at once when subtest is
113 complete.
