Robolectric: Robolectric 4.1 + Espresso, Wrap_Content error

[Aetherna]

Description

Having a TextView with text value filled out and height set to WRAP_CONTENT
Then Espresso doesn't find a TextView claiming it's height is 0.
Important: Setting a padding or fixed height fixes the problem.

androidx.test.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'is displayed on the screen to the user' doesn't match the selected view.
Expected: is displayed on the screen to the user
Got: "AppCompatTextView{id=2131230876, res-name=intro_register, visibility=VISIBLE, width=320, height=0, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=true, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, layout-params=android.widget.LinearLayout$LayoutParams@1b791dca, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=50.0, text=Register, input-type=0, ime-target=false, has-links=false}"

Steps to Reproduce

I have a very simple layout in a fragment: FrameLayout with LinearLayout inside with 2 TextViews:

My TextView has a height= "wrap_content" (no padding - important) and text value "Register"

    <import type="android.view.View" />
</data>

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".intro.ui.IntroFragment"
    android:id="@+id/intro_screen">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:text="I AR BLANK!"
        android:textColor="#f00" />

    <LinearLayout
        android:id="@+id/intro_login_options"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:layout_gravity="bottom"
        android:alpha="0"
        android:background="#b2b2b2"
        android:elevation="3dp"
        android:orientation="vertical"
        android:paddingTop="50dp"
        android:visibility="gone"
        tools:alpha="1"
        tools:visibility="visible">

        <TextView
            android:id="@+id/intro_register"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="@string/register_button_label" />

        <TextView
            android:id="@+id/intro_login"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="@string/login_button_label" />

    </LinearLayout>

</FrameLayout>

`

And a basic test:

`
@RunWith(AndroidJUnit4::class)
class IntroActivityTest {

@get:Rule
val rule = ActivityTestRule(IntroActivity::class.java, false, false)

@Test
fun `Registration flow`() {
    rule.launchActivity(null)

    onView(withId(R.id.intro_register)).check(matches(isDisplayed()))

}

}`

Thanks for the report. I suspect this is related to #4153 but we'll take a closer look to confirm

I was having the same problem on a EditText.

Digging a bit i've discovered that, even thought both width and height were set as WRAP_CONTENT, the actual width value was 0 while the height value was 48dp

After some tests removing a few properties from my EditText, i've noticed that the issue was related to the ems property from EditText.

Removing that property fixed the problem (at least in this case)

I don't know but maybe this info can be useful on solving this

Can you try on 4.3-alpha-2 with @LooperMode(PAUSED) + @TextLayoutMode(REALISTIC) and let us know if that fixes your issue? Please reopen if not.
