NAME
Test::Compile - Check whether Perl module files compile correctly
SYNOPSIS
#!perl -w
use strict;
use warnings;
use Test::Compile;
all_pm_files_ok();
DESCRIPTION
"Test::Compile" lets you check the validity of a Perl module file or Perl script file, and report its results in standard "Test::Simple" fashion.
BEGIN {
use Test::Compile tests => $num_tests;
pm_file_ok($file, "Valid Perl module file");
}
It's probably a good idea to run this in a BEGIN block. The examples below omit it for clarity.
Module authors can include the following in a t/00_compile.t file and have "Test::Compile" automatically find and check all Perl module files in a module distribution:
use Test::More;
eval "use Test::Compile 0.09";
Test::More->builder->BAIL_OUT(
"Test::Compile 0.09 required for testing compilation") if $@;
all_pm_files_ok();
You can also specify a list of files to check, using the "all_pm_files()" function supplied:
use strict;
use Test::More;
eval "use Test::Compile 0.09";
Test::More->builder->BAIL_OUT(
"Test::Compile 0.09 required for testing compilation") if $@;
my @pmdirs = qw(blib script);
all_pm_files_ok(all_pm_files(@pmdirs));
Or even (if you're running under Apache::Test):
use strict;
use Test::More;
eval "use Test::Compile 0.09";
Test::More->builder->BAIL_OUT(
"Test::Compile 0.09 required for testing compilation") if $@;
my @pmdirs = qw(blib script);
use File::Spec::Functions qw(catdir updir);
all_pm_files_ok(
all_pm_files(map { catdir updir, $_ } @pmdirs)
);
Why do the examples use "BAIL_OUT()" instead of "skip_all()"? Because testing whether a module compiles is important. "skip_all()" is ok to use with Test::Pod, because if the pod is malformed the program is still going to run. But checking whether a module even compiles is something else. Test::Compile should be mandatory, not optional.
FUNCTIONS
"pm_file_ok(FILENAME[, TESTNAME ])"
"pm_file_ok()" will okay the test if the Perl module compiles
correctly.
When it fails, "pm_file_ok()" will show any compilation errors as
diagnostics.
The optional second argument "TESTNAME" is the name of the test. If
it is omitted, "pm_file_ok()" chooses a default test name "Compile
test for FILENAME".
"pl_file_ok(FILENAME[, TESTNAME ])"
"pl_file_ok()" will okay the test if the Perl script compiles
correctly. You need to give the path to the script relative to this
distribution's base directory. So if you put your scripts in a
'top-level' directory called script the argument would be
"script/filename".
When it fails, "pl_file_ok()" will show any compilation errors as
diagnostics.
The optional second argument "TESTNAME" is the name of the test. If
it is omitted, "pl_file_ok()" chooses a default test name "Compile
test for FILENAME".
"all_pm_files_ok([@files/@directories])"
Checks all the files in @files for compilation. It runs
all_pm_files() on each file/directory, and calls the "plan()"
function for you (one test for each function), so you can't have
already called "plan".
If @files is empty or not passed, the function finds all Perl module
files in the blib directory if it exists, or the lib directory if
not. A Perl module file is one that ends with .pm.
If you're testing a module, just make a t/00_compile.t:
use Test::More;
eval "use Test::Compile 0.09";
plan skip_all => "Test::Compile 0.09 required for testing compilation"
if $@;
all_pm_files_ok();
Returns true if all Perl module files are ok, or false if any fail.
Or you could just let Module::Install::StandardTests do all the work
for you.
"all_pl_files_ok([@files])"
Checks all the files in @files for compilation. It runs pl_file_ok()
on each file, and calls the "plan()" function for you (one test for
each file), so you can't have already called "plan".
If @files is empty or not passed, the function uses all_pl_files()
to find scripts to test
If you're testing a module, just make a t/00_compile_scripts.t:
use Test::More;
eval "use Test::Compile 0.09";
plan skip_all => "Test::Compile 0.09 required for testing compilation"
if $@;
all_pl_files_ok();
Returns true if all Perl module files are ok, or false if any fail.
"all_pm_files([@dirs])"
Returns a list of all the perl module files - that is, files ending
in .pm - in $dir and in directories below. If no directories are
passed, it defaults to blib if blib exists, or else lib if not.
Skips any files in "CVS" or ".svn" directories.
The order of the files returned is machine-dependent. If you want
them sorted, you'll have to sort them yourself.
"all_pl_files([@files/@dirs])"
Returns a list of all the perl script files - that is, files ending
in .pl or with no extension. Directory arguments are searched
recursively . If arguments are passed, it defaults to script if
script exists, or else bin if bin exists. Skips any files in "CVS"
or ".svn" directories.
The order of the files returned is machine-dependent. If you want
them sorted, you'll have to sort them yourself.
