NAME

6       Test::Exec - Test that some code calls exec without terminating testing
7

VERSION

9       version 0.06

SYNOPSIS

12        use Test::More;
13        use Test::Exec;
14
15        is_deeply exec_arrayref { exec 'foo', 'bar', 'baz' }, [qw( foo bar baz )], 'found exec!';
16        is exec_arrayref { }, undef, 'did not exec!';
17
18        done_testing;
19

DESCRIPTION

21       Test::Exec provides the most simple possible tools for testing code
22       that might call "exec", which would otherwise end your test by calling
23       another program.  This code should detect and capture "exec" calls,
24       even if they are inside an "eval".
25
26       The concept was implementation was based on Test::Exit, but applied to
27       "exec" instead of "exit".
28

FUNCTIONS

30   exec_arrayref
31        exec_arrayref { ... }
32
33       runs the given code.  If the code calls "exec", then this function will
34       return an arrayref with its arguments.  If the code never calls "exec",
35       it will return "undef".
36
37   never_exec_ok
38        never_exec_ok { ... }
39
40       Runs the given code.  If the code calls "exec", then the test will fail
41       (but exec will be intercepted and not performed).
42

CAVEATS

44       This module installs its own version of "exec" in "CORE::GLOBAL::exec",
45       and may interact badly with any other code that is also trying to do
46       such things.

SEE ALSO

49       Test::Exit
50           Very similar to (and inspired) this module, but for "exit" testing
51           instead of "exec".
52
53       Test::Mock::Cmd
54           Provides an interface to mocking "system", "qx" and "exec".
