## NAME
    [Test::use::ok](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3Ause%3A%3Aok/markdown) - Alternative to [Test::More::use_ok](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3AMore%3A%3Auseok/markdown)

## SYNOPSIS
        use ok '[Some::Module](https://www.chedong.com/phpMan.php/perldoc/Some%3A%3AModule/markdown)';

## DESCRIPTION
    According to the [Test::More](https://www.chedong.com/phpMan.php/perldoc/Test%3A%3AMore/markdown) documentation, it is recommended to run "use_ok()" inside a "BEGIN"
    block, so functions are exported at compile-time and prototypes are properly honored.

    That is, instead of writing this:

        use_ok( '[Some::Module](https://www.chedong.com/phpMan.php/perldoc/Some%3A%3AModule/markdown)' );
        use_ok( '[Other::Module](https://www.chedong.com/phpMan.php/perldoc/Other%3A%3AModule/markdown)' );

    One should write this:

        BEGIN { use_ok( '[Some::Module](https://www.chedong.com/phpMan.php/perldoc/Some%3A%3AModule/markdown)' ); }
        BEGIN { use_ok( '[Other::Module](https://www.chedong.com/phpMan.php/perldoc/Other%3A%3AModule/markdown)' ); }

    However, people often either forget to add "BEGIN", or mistakenly group "use_ok" with other
    tests in a single "BEGIN" block, which can create subtle differences in execution order.

    With this module, simply change all "use_ok" in test scripts to "use ok", and they will be
    executed at "BEGIN" time. The explicit space after "use" makes it clear that this is a single
    compile-time action.
