NAME

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

VERSION

9       version 0.04
10

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

DESCRIPTION

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

FUNCTIONS

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

CAVEATS

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

SEE ALSO

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