This PR:

• [x] Adds a @covers annotation.
• [x] Renames the test class to be compliant with standards.

Adds a test class for wp_script_is() and moves existing tests into this class.

There is a test in WP_Dependencies_jQuery that covers wp_script_is(). The coverage is incomplete. This PR relocates that test to the new Tests_Dependencies_WpScriptIs test class.

Includes @covers for wp_script_is() which is a wrapper around WP_Scripts::query.

In 55562:

Tests: Use the data_ prefix for various data provider methods.

This aims to bring more consistency to the test suite, as the vast majority of data providers already use that prefix.

Includes moving some data providers next to the tests they are used in.

Follow-up to [55464].

See #57841.

[SergeyBiryukov]

In 55563:

Tests: Improve documentation and variable names in some formatting tests.

Includes documenting data provider values using hash notation in the tests for:

• convert_smilies()
• get_url_in_content()
• links_add_target()
• normalize_whitespace()

Follow-up to [26191], [26327], [26328], [26972], [55562].

See #57841.

In 55565:

Tests: Add test class for wp_script_is().

Changes:

• Adds a test class for wp_script_is().
• Moves WP_Dependencies_jQuery::test_wp_script_is_dep_enqueued() into this test class and splits it into 2 separate tests, happy and unhappy paths.
• Adds WP_Scripts::query @covers, as wp_script_is() is helper function for it.
• Relocates the global resetting from the test method to the clean_up_global_scope() method.

Follow-up to [52010], [29252].

Props hellofromTonya, antonvlasenko.
See #57841, #57958.

Thank you @anton-vlasenko! Committed via https://core.trac.wordpress.org/changeset/55565.

Tests: Add test class for wp_enqueue_stored_styles().

[54214] added tests and global reset for wp_enqueue_stored_styles() into the Tests_Theme_wpGetGlobalStylesheet. This changeset adds a new test case for the function and relocates its tests to it.

Follow-up to [54214].

Props costdev.

In 55567:

Tests: Add test class for wp_enqueue_stored_styles().

[54214] added the wp_enqueue_stored_styles() tests and clean_up_global_scope() reset global method to Tests_Theme_wpGetGlobalStylesheet.

This changeset relocates those tests a new test class specifically for wp_enqueue_stored_styles() and removes Tests_Theme_wpGetGlobalStylesheet::clean_up_global_scope() method.

Why not relocate the clean_up_global_scope() method to the new test class?
The test class extends from WP_Theme_UnitTestCase which includes this method.

Follow-up to [54214], [54703].

Props costdev.
See #57841.

Committed via https://core.trac.wordpress.org/changeset/55567.

[hellofromTonya]

In 55572:

Tests: Rename test class and improve tests for wp_get_global_stylesheet().

Changes include:

• Renames the test class to be compliant with test coding standards.
• Converts the test class to extend WP_Theme_UnitTestCase to reuse test fixtures.
• Implements data providers to encapsulate datasets and reduce code repetition.
• Adds a @covers annotation.
• Improves assertion messages to help with diagnosing failed tests.

Follow-up to [55567], [55148], [52682], [53916], [52675-52677].

In 55581:

Tests: Consistently sanitize expiration in the test suite's Memcached implementation.

In a previous commit, the ::sanitize_expiration() call in the ::add() method was moved closer to where the value is used.

This commit does the same for the other methods:

• ::cas()
• ::replace()
• ::set()
• ::setMulti()

Follow-up to [40561], [55577].

See #57841, #57963.

In 55583:

Tests: Improve get_pages() tests organization.

Includes:

• Renaming some tests for clarity.
• Moving some tests to a more appropriate place.
• Moving the @covers tag to the top of the class.
• Using consistent formatting for assertion messages.

Follow-up to [27767], [41849], [44587], [55569].

See #57841.

[SergeyBiryukov]

In 55588:

Tests: Move the wp_list_pages() test for CSS classes to a more appropriate place.

Back when this test was introduced, wp_list_pages() did not have its own test class.

It does now, so the test can be moved there, instead of being hidden among get_pages() tests.

Includes:

• Updating the test name for clarity.
• Adding an unique message for each assertion.

Follow-up to [27755], [28400].

See #57841.

[SergeyBiryukov]

In 55589:

Tests: Add a @ticket reference for wp_list_pages() CSS classes test.

Follow-up to [55588].

See #57841.

[SergeyBiryukov]

In 55590:

Tests: Move wp_dropdown_pages() tests to their own file.

This aims to make the tests more discoverable and easier to expand.

Includes removing a basic test hidden among get_pages() tests, as there is already a more comprehensive set of tests available.

Follow-up to [1279/tests], [28399], [31338].

See #57841.

[SergeyBiryukov]

In 55591:

Tests: Split the tests from post/template.php into individual test classes.

This aims to bring some consistency to the location of post template function tests, as well as to make the tests more discoverable and easier to expand.

Includes:

• Adding @covers tags.
• Renaming get_post_parent() and has_post_parent() tests to match the names of the functions.

Follow-up to [28398], [31522], [34654], [34950], [50127], [50396], [54717], [54726], [55590].

In 55742:

Tests: Move wp_cache_flush_runtime() next to wp_cache_flush().

This matches the function's placement in wp-includes/cache.php and brings more consistency.

Follow-up to [52772], [55741].

See #57841.

In 55745:

Tests: Use the function get_num_queries across all unit tests.

Replace use of $wpdb->num_queries with a function call to get_num_queries. This improves readability and consistency between tests.

Props SergeyBiryukov, peterwilsoncc, spacedmonkey.
See #57841.

In 55746:

Tests: Partial revert of r55745

Props mukesh27.

Committed.

In 55754:

Tests: Split the tests from user/author.php into individual test classes.

This aims to make get_the_author_*() tests more discoverable and easier to expand.

Follow-up to [691/tests], [692/tests], [695/tests], [28362], [31098], [34687], [53147], [54717], [54726], [55591].

Tests/Build tools: Various term related test improvements.

Modifies the tests for get_tag_link(), get_term() and get_term_field() to:

• use shared fixtures as possible
• improves variable names
• add @covers annotation as required

Props peterwilsoncc, costdev.
See #57841.

Adds a unit test to validate printing of @font-face declarations in a classic theme with a custom font defined in theme.json. Also updates test_font_face_generated_from_themejson() to use a data provider to include the new theme (webfonts-theme-classic).

Previously, only a block theme (webfonts-theme) was subject to this test.
