+There were 3 PHPUnit test runner warnings:
+
+1) Function does_not_exist cannot be configured as a deprecation trigger because it is not declared
+
+2) invalid-string cannot be configured as a deprecation trigger because it is not in ClassName::methodName format
+
+3) Method DoesNotExist::doesNotExist cannot be configured as a deprecation trigger because it is not declared
+
+OK, but there were issues!
