import "code.pfad.fr/check"
package check is a very minimal Go assertion package, usage example:
obj, err := newObj()
check.Equal(t, nil, err).Fatal() // Fatal will stop the test on failure (by calling testing.FailNow)
check.Equal(t, "property", obj.Field) // if this fails, the test continue
check.Equal(t, 0, obj.Answer("")).Log("wrong answer") // you can add some context on failure
check.Equal(t, 42, obj.Answer("Ultimate Question")).
Logf("question: %q", "Ultimate Question") // context with a printf-like syntax if preferred
check.Equal(t, 42, obj.Answer("other question")).
Logf("question: %q", "other question").
Log("reference", "Hitchhiker's Guide to the Galaxy"). // Log(f) can be chained
Fatal()
For slices see [Equals]; for not comparable structs see [EqualDeep] (all assertions begin with Equal for ease of discovery using auto-completion).
To get a nice diff, use the output of go-cmp as a Log argument:
import "github.com/google/go-cmp/cmp" check.EqualDeep(t, expectedObj, obj). Log(cmp.Diff(expectedObj, obj))
type Failed struct {
// contains filtered or unexported fields
}
Failed can be used to conditionnally add more information in case of failure (all method calls will be no-op if the check succeeded).
func Equal[T comparable](t testing.TB, want, got T) Failed
Equal calls t.Errorf if want != got.
func EqualDeep[T any](t testing.TB, want, got T) Failed
EqualDeep calls t.Errorf if !reflect.DeepEqual(want, got).
func Equals[S ~[]E, E comparable](t testing.TB, want, got S) Failed
Equals is the slice version of [Equal]. Calls t.Errorf if want != got.
func (f Failed) Fatal()
Fatal stops the test execution if the check failed (no-op otherwise), see [testing.T.FailNow].
func (f Failed) Log(args ...any) Failed
Log formats its arguments using default formatting, analogous to Println, and records the text in the error log if the check failed (no-op otherwise).
func (f Failed) Logf(format string, args ...any) Failed
Logf formats its arguments according to the format, analogous to Printf, and records the text in the error log if the check failed (no-op otherwise)
