Args:
provider_types: A list of provider types to include. If None, all providers are considered
*fields: Names of keys in an individual provider dict whose values will be returned when
used as test function arguments
**options: Explained below
The ``**options`` available are defined below:
* ``require_fields``: when fields passed are not present, skip them, boolean
* ``template_location``: Specification where a required tempalte lies in the yaml, If not
found in the provider, warning is printed and the test not collected. The spec
is a tuple or list where each item is a key to the next field (str or int).
The following test function arguments are special:
``provider``
the provider's CRUD object, either a :py:class:`cfme.cloud.provider.Provider`
or a :py:class:`cfme.infrastructure.provider.Provider`
Returns:
An tuple of ``(argnames, argvalues, idlist)`` for use in a pytest_generate_tests hook, or

Note:
Using the default 'function' scope, each test will be run individually for each provider
before moving on to the next test. To group all tests related to single provider together,
parametrize tests in the 'module' scope.
Note:
testgen for providers now requires the usage of test_flags for collection to work.

Args:
provider_types: A list of provider types to include. If None, all providers are considered
*fields: Names of keys in an individual provider dict whose values will be returned when
used as test function arguments
**options: Explained below
The ``**options`` available are defined below:
* ``required_fields``: when fields passed are not present, skip them
* ``choose_random``: choose a single provider from the list
* ``template_location``: Specification where a required tempalte lies in the yaml, If not
found in the provider, warning is printed and the test not collected. The spec
is a tuple or list where each item is a key to the next field (str or int).
The following test function arguments are special:
``provider``
the provider's CRUD object, either a :py:class:`cfme.cloud.provider.Provider`
or a :py:class:`cfme.infrastructure.provider.Provider`
Returns:
An tuple of ``(argnames, argvalues, idlist)`` for use in a pytest_generate_tests hook, or

Usage:

Note:
Using the default 'function' scope, each test will be run individually for each provider
before moving on to the next test. To group all tests related to single provider together,
parametrize tests in the 'module' scope.
Note:
testgen for providers now requires the usage of test_flags for collection to work.

Note:
Using the default 'function' scope, each test will be run individually for each provider

parametrize tests in the 'module' scope.

testgen for providers now requires the usage of test_flags for collection to work.
