Hi guys, is using Modifier object to something like,
Copy code
Button(onClick = { state.counter++ }, modifier = Modifier.tag("testTag"))
but on my UiTests the method findByTag is not recognizing the button, any insights on this?

If this is a 
findByTag
that returns a 
View
it won't work with compose; different kinds of tags attached to different kinds of objects 🙂
Compose generates UI out of smaller subcomponents than Views so the view-based test APIs can't get to the right level of granularity

You need to use 
TestTag
instead for testing, 
Modifier.tag
is a mechanism used by layouts in a different context. We should probably clean this up 🙂

@Mihai Popa I was reading the documentation; this TestTag acts in a similar way as preview? that is a kind of utility?
Copy code
@Composable fun TestTag(
    tag: "acceptButton", 
    children: acceptButton()
): Unit
?? is like that how it is supposed to work?
you know what… nvm for some reason I needed to clear cache and restart in order to see the object
