espresso intent validation: 'matched 0 intents', but 'Recorded intents'

Question

I want to simpley stub an intent that asks the system to open the web brower at a specified url after the user clicks a button

Intents.init()
val expectedIntent = allOf(hasAction(Intent.ACTION_VIEW), hasData(url))
intending(expectedIntent).respondWith(ActivityResult(0, null))

// here text view with link is clicked which will 
// launch browser to show web site
onView(withId(id)).perform(click())

intended(expectedIntent)
Intents.release()

When test is run I get

junit.framework.AssertionFailedError: Wanted to match 1 intents. Actually matched 0 intents.

IntentMatcher: (has action: is "android.intent.action.VIEW" and has data: is <false>)

Matched intents:[]

Recorded intents:

so clearly the intent is launched but not stubbed, but why?

Maybe I need to use test rule? However, I am launching fragment in isolation

@Before
fun init() {
    scenario = launchFragmentInContainer(null, R.style.Theme_AppCompat) {}
}

edit

Is the test rule required?

Maybe I need a fragment test rule?

Answer 1

Intent validation for intent type Intent.ACTION_VIEW is working, it's the hasData method which is causing fault.

I do not need any test rules apparently.

Answer 2

Since you didn't specify what url is, I can only guess that this parameter was not matching the expected value.

If you launched the browser by something like:

val url = "https://stackoverflow.com"
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
startActivity(intent)

Then this works perfectly fine in the test:

val url = "https://stackoverflow.com"
val expectedIntent = allOf(hasAction(Intent.ACTION_VIEW), hasData(url))
intending(expectedIntent).respondWith(Instrumentation.ActivityResult(0, null))

// perform click...

intended(expectedIntent)
