Changeset 54496 for trunk/tests/phpunit/tests/query.php

Timestamp:

Message:

Query: Avoid PHP notices when get_queried_object() returns null.

WP_Query methods assume that get_queried_object() would return a non-null value, which is not always the case.

This commit resolves various warnings in WP_Query along the lines of:

Attempt to read property "post_type" on null in wp-includes/class-wp-query.php on line 4338

Follow-up to [1728], [3639], [8807], [49119].

Fixes #29660.
