Expectations for Go

expec

Expectations testing package for Go

Usage

Import expec package directly into test. Only exported function is Expec()

Docs

Expec is largely inspired by RSpec expectations, and made as close as possible. Docs are pending.

Example

import (
	"testing"
	_ "github.com/dmajkic/expec"
)

func TestMe(t *testing.T) {
	variable := "Some string"

	// Equality
	Expec(t, variable).To.Eql("Some string")
	Expec(t, variable).NotTo.Eql("Some other string")

	// Match regexp
	Expec(t, variable).To.Match("string$")

	// Nil testing
	Expec(t, variable).NotTo.BeNil()

	// Errors
	variable2, err := someCall()
	Expec(t, err).To.BeNil()

	// Errors expected
	Expec(t, err).NotTo.BeNil()
	Expec(t, err).To.RaiseErr()
	Expec(t, err).To.RaiseErr("Something went wrong")
	Expec(t, err).To.RaiseErr(os.ErrNotExist)

	// Interfaces
	Expec(t, errors.new("error")).To.Implement((*error)(nil))

	// Slices
	Expec(t, []int{1,2,3,4,5}).To.Include(3)

	// Chaining And
	v := 1
	Expec(t, v).To.Eq(1).And.NotTo.Eq(3)
}
