   Here is an example:

   cat example_test.go

   package parser
   
   import (
   	"fmt"
   	. "github.com/pingcap/check"
   )
   
   var _ = Suite(&testExampleSuite{})
   
   type testExampleSuite struct {
   }
   
   func (s *testExampleSuite) TestExample(c *C) {
   	l := NewScanner("create table t (a int);")
   	var v yySymType
   	for {
   		result := l.Lex(&v)
   		if result == 0 || result == invalid {
   			break
   		}
   		fmt.Printf("%d\n", result)
   	}
   }

   go test -v github.com/pingcap/parser -check.f TestExample

   === RUN   TestT

   PASS: example_test.go:13: testExampleSuite.TestExample  0.001s

   The meaning of these numbers can be found in parser.go.
