.SH NAME
Test::Exec \- Test that some code calls exec without terminating testing
.SH VERSION
.IX Header "VERSION"
version 0.07
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\& use Test::More;
\& use Test::Exec;
\& 
\& is_deeply exec_arrayref { exec \*(Aqfoo\*(Aq, \*(Aqbar\*(Aq, \*(Aqbaz\*(Aq }, [qw( foo bar baz )], \*(Aqfound exec!\*(Aq;
\& is exec_arrayref { }, undef, \*(Aqdid not exec!\*(Aq;
\& 
\& done_testing;
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Test::Exec provides the most simple possible tools for testing code that might call \f(CW\*(C`exec\*(C'\fR, which
would otherwise end your test by calling another program.  This code should detect and capture \f(CW\*(C`exec\*(C'\fR
calls, even if they are inside an \f(CW\*(C`eval\*(C'\fR.
.PP
The concept was implementation was based on Test::Exit, but applied to \f(CW\*(C`exec\*(C'\fR instead of \f(CW\*(C`exit\*(C'\fR.
.SH FUNCTIONS
.IX Header "FUNCTIONS"
.SS exec_arrayref
.IX Subsection "exec_arrayref"
.Vb 1
\& exec_arrayref { ... }
.Ve
.PP
runs the given code.  If the code calls \f(CW\*(C`exec\*(C'\fR, then this function will return an arrayref with its
arguments.  If the code never calls \f(CW\*(C`exec\*(C'\fR, it will return \f(CW\*(C`undef\*(C'\fR.
.SS never_exec_ok
.IX Subsection "never_exec_ok"
.Vb 1
\& never_exec_ok { ... }
.Ve
.PP
Runs the given code.  If the code calls \f(CW\*(C`exec\*(C'\fR, then the test will fail (but exec will be intercepted
and not performed).
.SH CAVEATS
.IX Header "CAVEATS"
This module installs its own version of \f(CW\*(C`exec\*(C'\fR in \f(CW\*(C`CORE::GLOBAL::exec\*(C'\fR,
and may interact badly with any other code that is also trying to do
such things.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
.IP Test::Exit 4
.IX Item "Test::Exit"
Very similar to (and inspired) this module, but for \f(CW\*(C`exit\*(C'\fR testing instead of \f(CW\*(C`exec\*(C'\fR.
.IP Test::Mock::Cmd 4
.IX Item "Test::Mock::Cmd"
Provides an interface to mocking \f(CW\*(C`system\*(C'\fR, \f(CW\*(C`qx\*(C'\fR and \f(CW\*(C`exec\*(C'\fR.
