`TestCase::assertEquals(false, '0')` is failing

[mvorisek]

Q	A
PHPUnit version	9.5.10
PHP version	7.4
Installation Method	Composer

Summary

TestCase::assertEquals(false, '0')

currently produces:

Failed asserting that '0' matches expected false.

and does NOT match the php weak comparison: https://3v4l.org/qQkXC

also $this->assertEquals(false, 0) passes, so TestCase::assertEquals(false, '0') should pass too and be consistent

changing https://github.com/sebastianbergmann/comparator/blob/main/src/ScalarComparator.php#L61 to

-        if (is_string($expected) || is_string($actual)) {
+        if ((is_string($expected) && !is_bool($actual)) || (is_string($actual) && !is_bool($expected))) {

fixes the issue for me
