Ticket #53363: 53363-11-custom-assertions-improve-assertDiscardWhitespace.patch

File 53363-11-custom-assertions-improve-assertDiscardWhitespace.patch, 2.0 KB (added by jrf, 2 years ago)

WP_UnitTestCase_Base::assertDiscardWhitespace(): stabilize the custom assertion The assertDiscardWhitespace() method uses assertEquals() under the hood, meaning that in reality any type of actual/expected value should be accepted by the function. Fixed the documentation to reflect that. At the same time, only strings can contain whitespace differences, so the whitespace replacement should only be done when string values are passed. This will prevent potential passing null to non-nullable errors on PHP 8.1, if either of the inputs would turn out to be null.

Subject: [PATCH] WP_UnitTestCase_Base::assertDiscardWhitespace(): stabilize
 the custom assertion

The `assertDiscardWhitespace()` method uses `assertEquals()` under the hood, meaning that in reality any type of actual/expected value should be accepted by the function.
Fixed the documentation to reflect that.

At the same time, only strings can contain whitespace differences, so the whitespace replacement should only be done when string values are passed.

This will prevent potential `passing null to non-nullable` errors on PHP 8.1, if either of the inputs would turn out to be `null`.
