Test::Exit - Test that some code calls exit() without terminating testing


version 0.11


    use Test::More tests => 4;
    use Test::Exit;
    is exit_code { exit 75; }, 75, "procmail not found";
    exits_ok { exit 1; } "exiting exits";
    never_exits_ok { print "Hi!"; } "not exiting doesn't exit"l
    exits_zero { exit 0; } "exited with success";
    exits_nonzero { exit 42; } "exited with failure";


Test::Exit provides some simple tools for testing code that might call exit(), providing you with the status code without exiting the test file.

The only criterion tested is that the supplied code does or does not call exit(). If the code throws an exception, the exception will be propagated and you will have to catch it yourself. die()ing is not exiting for the purpose of these tests.

Unlike previous versions of this module, the current version doesn't use exceptions to do its work, so even if you call exit() inside of an eval, everything should work.



Runs the given code. If the code calls exit(), then exit_code will return a number, which is the status that exit() would have exited with. If the code never calls exit(), returns undef. This is the Test::Fatal-like interface. All of the other functions are wrappers for this one, retained for legacy purposes.


Tests that the supplied code calls exit() at some point.


Tests that the supplied code calls exit() with a nonzero value.


Tests that the supplied code calls exit() with a zero (successful) value.


Tests that the supplied code completes without calling exit().
