Line 1182 in 2e52cf6

t.Fatal("len is not 2. got: %v", len(ares))

Got errors when building a package with jsonpath lib:
/github.com/oliveagle/jsonpath/jsonpath_test.go:1182: Fatal call has possible formatting directive %v
/github.com/oliveagle/jsonpath/jsonpath_test.go:1185: Fatal call has possible formatting directive %v
/github.com/oliveagle/jsonpath/jsonpath_test.go:1188: Fatal call has possible formatting directive %v
/github.com/oliveagle/jsonpath/jsonpath_test.go:1235: Fatal call has possible formatting directive %v

t.Fatal should be t.Fatalf for above lines.
My go version is 1.10.2 and it works fine with version 1.9.4.
