This commit introduces a new test file `test/test_server_automation.py` containing `TestVARIANTEnumerator`. This test class verifies the functionality by creating and enumerating `IDispatch` objects and asserting the correct behavior of the `Next` method of `IEnumVARIANT`.
Refactored `test_Next` to `test_Next_single_item` and added `test_Next_multiple_items` to `TestVARIANTEnumerator` in `test_server_automation.py`. This new test verifies that `IEnumVARIANT.Next` can correctly fetch multiple items at once, ensuring proper handling of the `celt` parameter.
This commit introduces a new test method `test_Skip` to `TestVARIANTEnumerator` in `test_server_automation.py`. This test verifies the functionality of `IEnumVARIANT.Skip` by testing various skip scenarios, including skipping zero items, a single item, and more items than available, asserting correct return values for `Skip` and subsequent `Next` calls.
This commit introduces a new test method `test_Reset` to `TestVARIANTEnumerator` in `test/test_server_automation.py`. This test verifies the functionality of `IEnumVARIANT.Reset` by advancing the enumerator, resetting it, and then asserting that subsequent `Next` calls return items from the beginning of the enumeration.
This commit introduces a new test method `test_Clone` to `TestVARIANTEnumerator` in `test_server_automation.py`. This test verifies that calling `IEnumVARIANT.Clone` on a `VARIANTEnumerator` raises a `COMError` with `hresult.E_NOTIMPL`, as the `Clone` method is not implemented.
This commit introduces new test methods `test_dunder_iter` and `test_dunder_getitem` to `TestVARIANTEnumerator` in `test/test_server_automation.py`. `test_dunder_iter` verifies iteration support for `IEnumVARIANT` through `VARIANTEnumerator`. `test_dunder_getitem` confirms indexed access support and proper `IndexError` handling for out-of-bounds access.

Overview
This pull request introduces a new test module,
test_server_automation.py, dedicated to thoroughly testingserver.automation.VARIANTEnumerator.It includes tests for all essential methods of the
IEnumVARIANTinterface and ensures proper support for Python's iteration and indexing protocols (__iter__and__getitem__).Enhanced Test Coverage and Reliability
Ensures
IEnumVARIANTComplianceThe new tests verify the behavior of
Next(for both single and multiple item fetches),Skip,Reset, andClone(confirmingE_NOTIMPLwhere appropriate).This guarantees that
VARIANTEnumeratorcorrectly implements the standard COM enumeration contract, making it a reliable component for COM automation.Improves Pythonic Integration
By adding tests for
__iter__and__getitem__, this change ensures thatVARIANTEnumeratorseamlessly integrates with Python's native iterable and sequence protocols.
