NAME

6       Test2::Tools::Exception - Test2 based tools for checking exceptions
7

DESCRIPTION

9       This is the Test2 implementation of code used to test exceptions. This
10       is similar to Test::Fatal, but it intentionally does much less.
11

SYNOPSIS

13           use Test2::Tools::Exception qw/dies lives/;
14
15           like(
16               dies { die 'xxx' },
17               qr/xxx/,
18               "Got exception"
19           );
20
21           ok(lives { ... }, "did not die") or note($@);
22

EXPORTS

24       All subs are exported by default.
25
26       $e = dies { ... }
27           This will trap any exception the codeblock throws. If no exception
28           is thrown the sub will return undef. If an exception is thrown it
29           will be returned. This function preserves $@, it will not be
30           altered from its value before the sub is called.
31
32       $bool = lives { ... }
33           This will trap any exception thrown in the codeblock. It will
34           return true when there is no exception, and false when there is. $@
35           is preserved from before the sub is called when there is no
36           exception. When an exception is trapped $@ will have the exception
37           so that you can look at it.
38
39       $bool = try_ok { ... }
40       $bool = try_ok { ... } "Test Description"
41           This will run the code block trapping any exception. If there is no
42           exception a passing event will be issued. If the test fails a
43           failing event will be issued, and the exception will be reported as
44           diagnostics.
45
46           Note: This function does not preserve $@ on failure, it will be set
47           to the exception the codeblock throws, this is by design so that
48           you can obtain the exception if desired.

DIFFERENCES FROM TEST::FATAL

51       Test::Fatal sets $Test::Builder::Level such that failing tests inside
52       the exception block will report to the line where "exception()" is
53       called. I disagree with this, and think the actual line of the failing
54       test is more important. Ultimately, though Test::Fatal cannot be
55       changed, people probably already depend on that behavior.
