PHPUnit 13.1.8

Fixed

• #6595: Crash when before-class or after-class method fails with assertion failure
• #6599: TeamCity logger does not wrap failures in before-test methods with testStarted and testFinished
• #6601: Anonymous classes are not rejected with a clear error when creating a test double
• #6603: assertArrays*IgnoringOrder() fails on mixed scalar types and on reordered nested associative arrays
• MockBuilder::setMockClassName() and TestStubBuilder::setStubClassName() now reject values that are not valid unqualified PHP class identifiers, throwing the new InvalidClassNameException
• The regular expression used by Generator::ensureValidMethods() to validate method names passed to MockBuilder::onlyMethods() and addMethods() was not anchored, so any string containing a valid identifier substring (including strings with parentheses, braces, comments, or newlines) was accepted
