NAME

6       "IO::Async::LoopTests" - acceptance testing for IO::Async::Loop
7       subclasses
8

SYNOPSIS

10          use IO::Async::LoopTests;
11          run_tests( 'IO::Async::Loop::Shiney', 'io' );
12

DESCRIPTION

14       This module contains a collection of test functions for running
15       acceptance tests on IO::Async::Loop subclasses. It is provided as a
16       facility for authors of such subclasses to ensure that the code
17       conforms to the Loop API required by IO::Async.
18

TIMING

20       Certain tests require the use of timers or timed delays. Normally these
21       are counted in units of seconds. By setting the environment variable
22       "TEST_QUICK_TIMERS" to some true value, these timers run 10 times
23       quicker, being measured in units of 0.1 seconds instead. This value may
24       be useful when running the tests interactively, to avoid them taking
25       too long. The slower timers are preferred on automated smoke-testing
26       machines, to help guard against false negatives reported simply because
27       of scheduling delays or high system load while testing.

FUNCTIONS

32   run_tests
33          run_tests( $class, @tests )
34
35       Runs a test or collection of tests against the loop subclass given. The
36       class being tested is loaded by this function; the containing script
37       does not need to "require" or "use" it first.
38
39       This function runs "Test::More::plan" to output its expected test
40       count; the containing script should not do this.
41

TEST SUITES

43       The following test suite names exist, to be passed as a name in the
44       @tests argument to "run_tests":
45
46   io
47       Tests the Loop's ability to watch filehandles for IO readiness
48
49   timer
50       Tests the Loop's ability to handle timer events
51
52   signal
53       Tests the Loop's ability to watch POSIX signals
54
55   idle
56       Tests the Loop's support for idle handlers
57
58   process
59       Tests the Loop's support for watching child processes by PID
60
61       (Previously called "child")
62
63   control
64       Tests that the "run", "stop", "loop_once" and "loop_forever" methods
65       behave correctly
66
67   metrics
68       Tests that metrics are generated appropriately using Metrics::Any.
