NAME

6       Test::Stream::Manual::Components - Categorization and overview of
7       Test::Stream components and modules.

DESCRIPTION

10       This document categorizes the modues included in the Test-Stream
11       distribution.  This document also gives basic information about each
12       component, and what modules they connect with. This document is
13       primarily useful for maintainers and test tool authors.
14

ESSENTIAL INFRASTRUCTURE

16       The modules in this section are the most critical. These modules are
17       the heart of Test::Stream.
18
19       Test::Stream::Capabilities
20           The Test::Stream::Capabilities module detects various capabilities
21           of the current system, this includes the ability to fork or use
22           threads.
23
24       Test::Stream::Context
25           The Test::Stream::Context module is easily the most important
26           module in Test::Stream. The context object is the primary interface
27           for tool authors. The context object ties everything together and
28           ensures events get to the correct hub. The context object also
29           makes it possible to report the filename and line numbers of
30           errors.
31
32       Test::Stream::DebugInfo
33           The Test::Stream::DebugInfo is used by the context object to track
34           filename, line numbers, todo status, and other information that is
35           important when reporting a test failure.
36
37       Test::Stream::Event
38           The Test::Stream::Event module is the base class for all events,
39           such as "Ok", "Diag", etc.
40
41       Test::Stream::Exporter
42           The Test::Stream::Exporter module is used by Test::Stream to
43           accomplish export behavior well beyond what Exporter is capable of.
44
45           The Test::Stream::Exporter::Meta module is a key component of
46           Test::Stream::Exporter.
47
48       Test::Stream::Formatter::TAP
49           Test::Stream::Formatter::TAP is the TAP output formatter. This
50           module is used whenever Test::Stream outputs TAP.
51
52       Test::Stream::HashBase
53           Test::Stream::HashBase is the object builder used in most
54           Test::Stream modules. It provides constructors and accessor
55           generators.
56
57       Test::Stream::Hub
58           Test::Stream::Hub is responsible for routing events to output
59           handlers. This module also provides several hooks for testing
60           tools.
61
62       Test::Stream::IPC
63           Test::Stream::IPC is responsible for sending events between
64           processes and threads. Test::Stream::IPC::Files is the default IPC
65           driver.
66
67       Test::Stream::Stack
68           The Test::Stream::Stack module manages a stack of hubs. In
69           Test::Stream there can be several hubs and they all live on a stack
70           like this. Events typically go to whichever hub is on top.
71
72       Test::Stream::State
73           Test::Stream::State tracks a tests state, this includes the number
74           of tests, the number of passes, and the number of failures.
75
76       Test::Stream::Sync
77           The Test::Stream::Sync module is where global shared state is
78           managed.
79
80       Test::Stream::Table
81           Test::Stream::Table is used to generate nicely formatted tables.
82           Test::Stream::Table::LineBreak breaks lines of text so that they
83           fit in a table.
84
85       Test::Stream::Util
86           Test::Stream::Util is a collection of general purpose functions
87           used in almost every component of Test::Stream.
88
89   ESSENTIAL EVENT TYPES
90       Test::Stream::Event::Bail
91           Test::Stream::Event::Bail is an event that is issued when there is
92           a catastrophic failure and all testing should end.
93
94       Test::Stream::Event::Diag
95           Test::Stream::Event::Diag is used to output a message that should
96           always be displayed.
97
98       Test::Stream::Event::Exception
99           Test::Stream::Event::Exception is used when an exception is cought
100           and needs to be reported.
101
102       Test::Stream::Event::Note
103           Test::Stream::Event::Note is used to output an informational
104           message that does not always need to be seen.
105
106       Test::Stream::Event::Ok
107           Test::Stream::Event::Ok is used to represent a single pass or
108           failure.
109
110       Test::Stream::Event::Plan
111           Test::Stream::Event::Plan is used when a plan is set.
112
113       Test::Stream::Event::Subtest
114           Test::Stream::Event::Subtest is used to run an isolated sub-group
115           of tests.
116
117       Test::Stream::Event::Waiting
118           Test::Stream::Event::Waiting is used by the IPC system to pass
119           along a note that the primary process/thread is finished.
120

242           events for testing purposes.
243
244           The Test::Stream::Hub::Interceptor and
245           Test::Stream::Hub::Interceptor::Terminator modules are used under
246           the hood to achieve this functionality.
247

249           Test::Stream::Plugin::LoadPlugin can be used to load plugins at
250           run-time, primarily useful when testing plugins.
251
252       Test::Stream::Plugin::Mock

257
258       Test::Stream::Plugin::SRand
259           Test::Stream::Plugin::SRand can be used to set the random seed to
260           the current date. This is useful for making a test run consistent
261           over any given day.
262
263       Test::Stream::Plugin::SkipWithout
264           Test::Stream::Plugin::SkipWithout can be used to skip test files

266
267       Test::Stream::Plugin::Spec
268           Experimental: This plugin is still considered experimental. It is
269           included in the dist because it is used heavily in the tests for
270           Test::Stream. This is still considered experimental because the API
271           is not completely finalized, but it does work well, is fully
272           tested, and will not be removed.
273
274           Test::Stream::Plugin::Spec provides RSPEC like functionality. This
275           is essentially a much more advanced form of subtests.
