Method AssertRenderScreen

core/testing.go:42–55

AssertRenderScreen is the same as [Body.AssertRender] except that it asserts the rendered image of the entire screen, not just this body. It should be used for multi-scene tests like those of snackbars and dialogs.

(t imagex.TestingT, filename string, fun ...func())

// rendered image of the entire screen, not just this body. It should be used for
// multi-scene tests like those of snackbars and dialogs.
func (b *Body) AssertRenderScreen(t imagex.TestingT, filename string, fun ...func()) {
	b.runAndShowNewWindow()
	for i := 0; i < len(fun); i++ {
		fun[i]()
		b.waitNoEvents()
	}
	if len(fun) == 0 {
		// we didn't get it above
		b.waitNoEvents()
	}

	system.AssertCapture(t, filename)
	b.Close()
}

// runAndShowNewWindow runs a new window and waits for it to be shown.
func (b *Body) runAndShowNewWindow() {
