# qt: quicker Go tests `go get github.com/go-quicktest/qt` Package qt provides a collection of Go helpers for writing tests. It uses generics, so requires Go 1.19 at least. For a complete API reference, see the [package documentation](https://pkg.go.dev/github.com/go-quicktest/qt). Quicktest helpers can be easily integrated inside regular Go tests, for instance: import "github.com/go-quicktest/qt" func TestFoo(t *testing.T) { t.Run("numbers", func(t *testing.T) { numbers, err := somepackage.Numbers() qt.Assert(t, qt.DeepEquals(numbers, []int{42, 47}) qt.Assert(t, qt.ErrorMatches(err, "bad wolf")) }) t.Run("nil", func(t *testing.T) { got := somepackage.MaybeNil() qt.Assert(t, qt.IsNil(got), qt.Commentf("value: %v", somepackage.Value)) }) } ### Assertions An assertion looks like this, where `qt.Equals` could be replaced by any available checker. If the assertion fails, the underlying `t.Fatal` method is called to describe the error and abort the test. qt.Assert(t, qt.Equals(someValue, wantValue)) If you don’t want to abort on failure, use `Check` instead, which calls `Error` instead of `Fatal`: qt.Check(t, qt.Equals(someValue, wantValue)) The library provides some base checkers like `Equals`, `DeepEquals`, `Matches`, `ErrorMatches`, `IsNil` and others. More can be added by implementing the Checker interface. ### Other helpers The `Patch` helper makes it a little more convenient to change a global or other variable for the duration of a test.
