Sugar is a simple wrapper around testing.T that clarifies and colorizes test output and and better organizes test funcs. For full documentation see the godoc. If you've got any questions, check the gitter or tweet @marksalpeter.
With sugar, your test output will look sexy, like this ;) :
and test code will be organized more clearly like this:
package main
import (
"github.com/marksalpeter/sugar"
"testing"
)
type Struct struct {
Field string
}
func TestStruct(t *testing.T) {
s := sugar.New(t)
s.Must("this must be true or t.FailNow() will be called", func(_ sugar.Log) bool {
return true
})
s.Warn("this won't cause a failure, it just prints a warning", func(_ sugar.Log) bool {
return false
})
s.Assert("this must be true or t.Fail() will be called!", func(_ sugar.Log) bool {
return false
})
s.Assert("and finally this is a full demonstration of the logger", func(log sugar.Log) bool {
log("by default, %s works like fmt.Printf", "sugar.Log")
log("but, if you just pass in structs, it will print them with their field names")
log(&Struct{Field: "1"}, &Struct{Field: "2"}, &Struct{Field: "3"})
nestedLogger := sugar.NewLogger()
nestedLogger.Log("it is also possible to nest logs by creating a new logger")
log(nestedLogger)
log("finally, log.Compare will compare any two interfaces and log the differences")
return log.Compare([]Struct{
Struct{Field: "this equals the other one"},
Struct{Field: "this does not"},
}, []Struct{
Struct{Field: "this equals the other one"},
Struct{Field: "equal this one"},
})
})
}
