Matchers is simple package to allow go programmers write java like tests. It is compatible with go test, self described and self tested (see matchers_test.go).
package main
import (
"testing"
. "github.com/aandryashin/matchers"
)
func TestSample(t *testing.T) {
// Assertion
AssertThat(t, true, Is{true})
// Expectation
AssertThat(t, Expect{true, Not{true}}, Fails{})
}It is easy to implement your own custom matcher and combine it with others.
package main
import (
"fmt"
"testing"
. "github.com/aandryashin/matchers"
)
type Contains struct {
S string
}
func (m Contains) Match(i interface{}) bool {
for _, v := range i.([]string) {
if v == m.S {
return true
}
}
return false
}
func (m Contains) String() string {
return fmt.Sprintf("contains %v", m.S)
}
func TestContains(t *testing.T) {
AssertThat(t, []string{"one", "two", "three"}, Contains{"two"})
AssertThat(t, Expect{[]string{"one", "two", "three"}, Contains{"four"}}, Fails{})
}
