Ticket #53363: 53363-10-custom-assertions-more-stabilizing.patch

File 53363-10-custom-assertions-more-stabilizing.patch, 4.0 KB (added by jrf, 2 years ago)

WP_UnitTestCase_Base: more improvements to custom assertions The assertEqualFields() method expects an object and a fields array as inputs and subsequently approaches the received parameters as such, but did not verify whether the received parameters are of the expected types. Along the same lines, the assertSameSets(), assertEqualSets(), assertSameSetsWithIndex() and the assertEqualSetsWithIndex() methods all expect arrays for both the actual as well as the expected values and uses the array function [k]sort() on both, but never verified that the received inputs were actually arrays, which could lead to PHP errors on the sorting function calls.

Subject: [PATCH] WP_UnitTestCase_Base: more improvements to custom assertions

The `assertEqualFields()` method expects an object and a fields array as inputs and subsequently approaches the received parameters as such, but did not verify whether the received parameters are of the expected types.

Along the same lines, the `assertSameSets()`, `assertEqualSets()`, `assertSameSetsWithIndex()` and the `assertEqualSetsWithIndex()` methods all expect arrays for both the actual as well as the expected values and uses the array function `[k]sort()` on both, but never verified that the received inputs were actually arrays, which could lead to PHP errors on the sorting function calls.
