Functions

func CheckError

func CheckError(t *testing.T, e error)

CheckError calls Fatal if error is not nil.

func CompareFloats

func CompareFloats(t *testing.T, expected float64, actual float64, message string, tol float64)

CompareFloats compares floats using Comparef64.

func CompareSliceFloat

func CompareSliceFloat(t *testing.T, expected []float64, actual []float64, message string, tol float64)

CompareSliceFloat compares slices elementwise using Comparef64.

func CompareSliceInt

func CompareSliceInt(t *testing.T, expected []int, actual []int, message string)

CompareSliceInt compares two slices of ints elementwise.

func Comparef64

func Comparef64(f1, f2, tol float64) bool

Comparef64 returns true if |f2/f1-1| < tol.

func Fatal

func Fatal(err error)

Fatal logs a fatal errors and exits.

func PanicIf

func PanicIf(err error)

PanicIf panics if error is not nil.

func ReadResults

func ReadResults(fn string) (results map[string]*Result, e error)

Read a results file.

func WriteResults

func WriteResults(results map[string]*Result, fn string) error

Write a collection of results to a file.

Types

type Result

type Result struct {
	BatchID string   `json:"batchid"`
	Ref     []string `json:"ref,omitempty"`
	Hyp     []string `json:"hyp,omitempty"`
}
