TestRender

func TestRender(root View, opts ...TestOption) *RenderedTree

TestRender mounts a component without opening a Fyne window. It resolves nested components (including Viewables and Define closures) and returns a tree you can query and interact with.

func TestCounterIncrements(t *testing.T) {
    tree := gova.TestRender(Counter{})
 
    if got := tree.FindText(0).Value; got != "count: 0" {
        t.Fatalf("unexpected initial text: %q", got)
    }
 
    tree.FindButtonByLabel("+1").Click()
 
    if got := tree.FindText(0).Value; got != "count: 1" {
        t.Fatalf("unexpected text after click: %q", got)
    }
}

Test options

type TestOption func(*Scope)
 
func WithStore[T any](key *StoreKey[T], value T) TestOption

WithStore pre-provides a store on the test scope so components that UseStore can read a known initial value.

tree := gova.TestRender(NotesView{},
    gova.WithStore(NotesStore, NotesModel{Notes: []Note{
        {ID: 1, Title: "example"},
    }}),
)
