LegacyLithoViewRule
Deprecated
Please use LithoViewRule and TestLithoView instead
This test utility allows clients to test assertion on the view hierarchy rendered by a Litho components. The utility has methods to override the default {@link LithoView}, {@link ComponentTree}, width, and height specs.
@RunWith(AndroidJUnit4::class)
class LithoSampleTest {
@Rule @JvmField val lithoViewRule = LegacyLithoViewRule()
@Test
fun test() {
lithoViewRule.render { TestComponent() }
// or you can use setRoot/measure/layout for more fine-grained control
val lithoViewTest = lithoViewRule.attachToWindow().setRoot(TestComponent()).measure().layout()
// Test your assertions on the litho view.
}

Types
Class which exposes interactions that can take place on a view. Exposing interactions in this class ensures that they are only accessible within act, where the proper threading is taken into account to properly update the components and views.
Properties
