# Test::API(3pm)

Test a list of subroutines provided by a module

## NAME

Test::API - Test a list of subroutines provided by a module

## VERSION

version 0.010

## SYNOPSIS

```
    use Test::More tests => 3;
    use Test::API;
    require_ok( 'My::Package' );
    public_ok ( 'My::Package', @names );
    import_ok ( 'My::Package',
        export    => [ 'foo', 'bar' ],
        export_ok => [ 'baz', 'bam' ],
    );
    class_api_ok( 'My::Class', @methods );
```

## DESCRIPTION

This simple test module checks the subroutines provided by a module.  This is useful for confirming a planned API in testing and ensuring that other functions aren't unintentionally included via import.

## USAGE

Note: Subroutines starting with an underscore are ignored, as are a number of other methods not intended to be called directly by end-users.

```
  import unimport bootstrap
  AUTOLOAD BUILD BUILDARGS CLONE CLONE_SKIP DESTROY DEMOLISH
  TIESCALAR TIEARRAY TIEHASH TIEHANDLE
  FETCH STORE UNTIE FETCHSIZE STORESIZE POP PUSH SHIFT UNSHIFT SPLICE
  DELETE EXISTS EXTEND CLEAR FIRSTKEY NEXTKEY PRINT PRINTF WRITE
  READLINE GETC READ CLOSE BINMODE OPEN EOF FILENO SEEK TELL SCALAR
  MODIFY_REF_ATTRIBUTES MODIFY_SCALAR_ATTRIBUTES MODIFY_ARRAY_ATTRIBUTES
  MODIFY_HASH_ATTRIBUTES MODIFY_CODE_ATTRIBUTES MODIFY_GLOB_ATTRIBUTES
  MODIFY_FORMAT_ATTRIBUTES MODIFY_IO_ATTRIBUTES
  FETCH_REF_ATTRIBUTES FETCH_SCALAR_ATTRIBUTES FETCH_ARRAY_ATTRIBUTES
  FETCH_HASH_ATTRIBUTES FETCH_CODE_ATTRIBUTES FETCH_GLOB_ATTRIBUTES
  FETCH_FORMAT_ATTRIBUTES FETCH_IO_ATTRIBUTES
```

Therefore, do not include any of these in a list of expected subroutines.

### public\_ok

```
  public_ok( $package, @names );
```

This function checks that all of the `@names` provided are available within the `$package` namespace and that \*only\* these subroutines are available.  This means that subroutines imported from other modules will cause this test to fail unless they are explicitly included in `@names`.

### class\_api\_ok

```
  class_api_ok( $class, @names );
```

A variation of `"public_ok"` for object-oriented modules. Allows superclasses to fill in "missing" subroutines, but "extra" methods provided by superclasses will not cause the test to fail.

### import\_ok

```
  import_ok ( $package, %spec );
```

This function checks that `$package` correctly exports an expected list of subroutines and \*only\* these subroutines.  The `%spec` generally follows the style used by \[Exporter\], but in lower case:

```
  %spec = (
    export    => [ 'foo', 'bar' ],  # exported automatically
    export_ok => [ 'baz', 'bam' ],  # optional exports
  );
```

For `"export_ok"`, the test will check for public functions not listed in `"export"` or `"export_ok"` that can be imported and will fail if any are found.
