Comment (by pento):

 In [changeset:"45665" 45665]:
 {{{
 #!CommitTicketReference repository="" revision="45665"
 Coding Standards: Move the remaining PHPCS errors to report as warnings,
 and add Travis tests.

 The remaining error-level coding standards issues (specifically,
 associated with the sniffs `WordPress.PHP.YodaConditions.NotYoda`,
 `WordPress.NamingConventions.ValidVariableName.VariableNotSnakeCase`,
 `WordPress.DB.PreparedSQL.InterpolatedNotPrepared`,
 `WordPress.DB.PreparedSQL.NotPrepared`, and
 `WordPress.Files.FileName.InvalidClassFileName`) are marked as warnings,
 until they're all addressed.

 This change allows us to run linting on Travis across the entire codebase,
 ensuring no other error-level violations can be introduced.

 Additionally, PHPCS will now cache results locally, drastically improving
 performance for subsequent checks: scanning the entire codebase takes 1-2
 minutes the first time, and less than one second for subsequent checks.

 See #47632.
