These three tests create a 'test' folder under $MYSQL_TMP_DIR when they
specify CREATE TABLE ... DATA DIRECTORY='$MYSQL_TMP_DIR';

But did not remove it at the end with  --rmdir $MYSQL_TMP_DIR/test
When these tests happen to run just before innodb.create_tablespace.test
it will fail at line 248 which is;
--mkdir $MYSQL_TMP_DIR/test
