+### Fixed
+
+* Ignore the `IncorrectWhitespaceBeforeDeclare` error emitted by the `SlevomatCodingStandard.TypeHints.DeclareStrictTypes` sniff.
+
+  In my personal projects, I usually have 2 newlines before the `declare` statement. One before the file header comment and one after. However, in tests, I have no file header comment, so there is only 1 newline before the `declare` statement. Since I like my tests to follow the same coding standard as the rest of my source, it is easiest to ignore this error.
