Test2::Tools::Exports - Tools for validating exporters.
These are tools for checking that symbols have been imported into your namespace.
use Test2::Tools::Exports use Data::Dumper; imported_ok qw/Dumper/; not_imported_ok qw/dumper/;
All subs are exported by default.
Check that the specified symbols exist in the current package. This will not find inherited subs. This will only find symbols in the current packages symbol table. This WILL NOT confirm that the symbols were defined outside of the package itself.
imported_ok( '$scalar', '@array', '%hash', '&sub', 'also_a_sub' );
@SYMBOLS can contain any number of symbols. Each item in the array must be a string. The string should be the name of a symbol. If a sigil is present then it will search for that specified type, if no sigil is specified it will be used as a sub name.
@SYMBOLS
Check that the specified symbols do not exist in the current package. This will not find inherited subs. This will only look at symbols in the current packages symbol table.
not_imported_ok( '$scalar', '@array', '%hash', '&sub', 'also_a_sub' );
Before perl 5.10 it is very difficult to distinguish between a package scalar that is undeclared vs declared and undefined. Currently imported_ok and not_imported_ok cannot see package scalars declared using our $var unless the variable has been assigned a defined value.
imported_ok
not_imported_ok
our $var
This will pass on recent perls, but fail on perls older than 5.10:
use Test2::Tools::Exports; our $foo; # Fails on perl onlder than 5.10 imported_ok(qw/$foo/);
If $foo is imported from another module, or imported using use vars qw/$foo/; then it will work on all supported perl versions.
$foo
use vars qw/$foo/;
use Test2::Tools::Exports; use vars qw/$foo/; use Some::Module qw/$bar/; # Always works imported_ok(qw/$foo $bar/);
