ExtUtils::MakeMaker::CUseraContributed Perl DoExtUtils::MakeMaker::Coverage(3)NAMEExtUtils::MakeMaker::Coverage - add a Makefile target to determine test
coverage using Devel::Cover
VERSION
Version 0.05
SYNOPSIS
This module adds an additional target to the Makefile generated by
"ExtUtils::MakeMaker". The target, "testcover", calls "cover", the
command-line script to generate test coverage statistics, to clean up
any data from a previous run. It then runs the tests, as if "make
test" was run, then calls "cover" again to generate the coverage
statistics.
# In Makefile.PL
use ExtUtils::MakeMaker;
use ExtUtils::MakeMaker::Coverage;
...
# if you already have a MY::postamble...
sub MY::postamble {
testcover();
...
}
# if you wish to tweak the testcover target that will be written,
# alter it's configuration.
$conf = ExtUtils::MakeMaker::Coverage->config;
In your shell
> perl Makefile.PL
> make
> make testcover
METHODS
testcover
This method is exported for use when there already is a MY::postamble
in the Makefile.PL. In that case, adding a call to the testcover
method will add the necessary Makefile steps.
config
This method returns the internal config object used by this package to
create the "testcover" target for the Makefile.
You can change parts of the "testcover" target by setting accessors of
this object
binary
The value to use for the "cover" binary. Defaults to "cover".
format
The output format to use for "cover -report". Defaults to none,
using "cover"'s default settings. Consult "perldoc cover" for
documentation on its "-report" switch.
ignore
An array ref of patterns to ignore when generating the coverage
report. Defaults to an empty list. Consult "perldoc cover" for
documentation on its "-ignore" switch.
files
An array ref of test files to run for this coverage reprort.
Defaults to the "$(TESTFILES)" variable as defined in your
"Makefile". Consult "perldoc ExtUtils::MakeMaker" for details.
cover_statement
Boolean indicating whether to run coverage on statements. Defaults
to true. Consult "perldoc cover" for documentation on its
"-coverage" switch.
cover_branch
Boolean indicating whether to run coverage on branches. Defaults to
true. Consult "perldoc cover" for documentation on its "-coverage"
switch.
cover_subroutine
Boolean indicating whether to run coverage on subroutines. Defaults
to true. Consult "perldoc cover" for documentation on its
"-coverage" switch.
cover_condition
Boolean indicating whether to run coverage on conditions. Defaults
to true. Consult "perldoc cover" for documentation on its
"-coverage" switch.
cover_pod
Boolean indicating whether to run coverage on POD. Defaults to
true. Consult "perldoc cover" for documentation on its "-coverage"
switch.
Example:
$config = ExtUtils::MakeMaker::Coverage->config;
$config->pod(0); # disable pod coverage
$config->files(['t/1.t', 't/2.t']); # use these test files only
$config->ignore(['SCCS']); # ignore files with these
# patterns in their path
NOTES
This is alpha quality code in terms of features. For this module to be
usable for as many modules as possible, the following additional
features are needed.
BSD make
From my testing, if you run the testcover step using a BSD make,
you will get coverage statistics for the test scripts. This is not
at all useful. gmake is suggested until this issue is resolved.
nmake
I have not tested this enough with nmake. I have done some initial
changes to make it work, but it requires more refactoring to get to
where I'd like to see it. Expect full support in a release or two.
