在Symfony2中生成Phpunit骨架测试类

I got my phpunit test in symfony though I am trying to use PhpUnit skelgen to generate skeleton for my test classes. I had a look at the PhpUnit documentation

phpunit-skelgen --test -- "project\Calculator" Calculator.php

My path for the file i want to generate skeleton is:

Boltmail\UserBundle\BoltmailFactory\UserLoginFactory.php

and following the documentation i have inserted the following:

./bin/phpunit-skelgen --test -- "Boltmail\UserBundle\BoltmailFactory\UserLoginFactory" UserLoginFactory.php

And this keeps on throwing InvalidArgumentException:

 [InvalidArgumentException]                                                      
  Command "Boltmail\UserBundle\BoltmailFactory\UserLoginFactory" is not defined.

Any idea guys where i am going wrong with all the before you ask yes i have installed phpunit and phpunit-skelgen through my composer.json

OK After a suggestion in a below answer i changed my terminal command to this:

./bin/phpunit-skelgen --bootstrap app\bootstrap.php.cache --test -- "Boltmail\UserBundle\BoltmailFactory\UserLoginFactory"

Now I get this error:

[InvalidArgumentException]                        
  Command "appbootstrap.php.cache" is not defined.

Before all these i did:

composer update which installed bootstrap/php/cache under app/ dir

You need to add

--bootstrap app\bootstrap.php.cache to arguments for phpunit-skelgen
