Test2::Plugin::SourceDiag - Output the lines of code that resulted in a failure.
This plugin injects diagnostics messages that include the lines of source that executed to produce the test failure. This is a less magical answer to Damian Conway's Test::Expr module, that has the benefit of working on any Test2 based test.
This test:
use Test2::V0;
use Test2::Plugin::SourceDiag;
ok(0, "fail");
done_testing;
Produces the output:
not ok 1 - fail
Failure source code:
# ------------
# 4: ok(0, "fail");
# ------------
# Failed test 'fail'
# at test.pl line 4.
use Test2::Plugin::SourceDiag show_source => $bool;
show_source is set to on by default. You can specify 0 if you want to
turn it off.
Source output:
not ok 1 - fail
Failure source code:
# ------------
# 4: ok(0, "fail");
# ------------
# Failed test 'fail'
# at test.pl line 4.
use Test2::Plugin::SourceDiag show_args => $bool
show_args is set to off by default. You can turn it on with a true value.
Args output:
not ok 1 - fail
Failure source code:
# ------------
# 4: ok($x, "fail");
# ------------
# Failure Arguments: (0, 'fail') <----- here
# Failed test 'fail'
# at test.pl line 4.
use Test2::Plugin::SourceDiag inject_name => $bool
inject_name is off by default. You may turn it on if desired.
This feature will inject the source as the name of your assertion if the name has not already been set. When this happens the failure source diag will not be seen as the name is sufficient.
not ok 1 - ok($x eq $y);
# Failed test 'ok($x eq $y);'
# at test.pl line 4.
note: This works perfectly fine with multi-line statements.
