"""
|
|
This file contains a minimal set of tests for compliance with the extension
|
|
array interface test suite, and should contain no other tests.
|
|
The test suite for the full functionality of the array is located in
|
|
`pandas/tests/arrays/`.
|
|
|
|
The tests in this file are inherited from the BaseExtensionTests, and only
|
|
minimal tweaks should be applied to get the tests passing (by overwriting a
|
|
parent method).
|
|
|
|
Additional tests should either be added to one of the BaseExtensionTests
|
|
classes (if they are relevant for the extension interface for all dtypes), or
|
|
be added to the array-specific tests in `pandas/tests/arrays/`.
