 WP_Query is one of the most critical classes in WordPress. It holds a lot
 of features and complicated rules to generate the SQL queries to fetch
 posts from the databases.

 Working on bug fixes and new features for it is very tricky because one is
 always afraid that any change to it could silently break things and tear
 the world apart.

 One way to make us feel more secure when working with this class is to
 have better test coverage for it. Looking at the tests we currently have I
 found very few tests for this class.

 I've created this ticket to organize and receive patches to add tests to
 this class.

 Below I organized the WP_Query parameters we should, at first, create
 tests for. Once we have tests for them individually, we can think of a way
 to write tests that combine different parameters.


 * Author params
  * author
  * author_name
  * author__in
  * author__not_in

 * Category params
  * cat
  * category_name
  * category__and
  * category__in
  * category__not_in

 * Tag params
  * tag
  * tag_id
  * tag__and
  * tag__in
  * tag__not_in
  * tag_slug__and
  * tag_slug__in

 * Tax_query

 * Meta_query

 * date_query

 * post_mime_type

 * fields

 * name

 * page_id

 * pagename

 * post_parent

 * post_parent__in

 * post_parent__not_in

 * post__in

 * post__not_in

 * post_name__in

 * has_password

 * post_password

 * post_type

 * post_status

 * comment_count

 * nopaging

 * posts_per_page

 * offset

 * paged

 * ignore_sticky_posts

 * order and orderby paramaters


 PS - what motivated me to open this ticket (and start working on these
 tests) was #48556 and #44737
