4. Test your app

Describe the problem
4 of the 19 tests faill

For 3 of the tests, they all fail for the same reason.
The test is not handling the string resources with variables.
This happens for age and hobbies

<string name="dog_age">Age: %1$s</string>
<string name="dog_hobbies">Hobbies: %1$s</string>

But in BaseTest.hasListItemContent() you have this:

    onView(withText(age))
        .check(matches(isDisplayed()))
    onView(withText(hobbies))
        .check(matches(isDisplayed()))

This won't work because the actual TextView will be a like "Age: 7" and you can calling withText("7")

So to fix you can just do this:

1. Add a private method so you don't duplicate your code (dry)

   private fun getResourceStringWithVariable(id: Int, variable: String): String? {
   val targetContext: Context = ApplicationProvider.getApplicationContext()
   return targetContext.getResources().getString(id, variable)
   }

2. Fix your tests to be this:

    onView(withText(getResourceStringWithVariable(R.string.dog_age, age)))
        .check(matches(isDisplayed()))
    onView(withText(getResourceStringWithVariable(R.string.dog_hobbies, hobbies)))
        .check(matches(isDisplayed()))
   

The fourth test HorizontalListTests.horizontal_scrolling() is failing, because at least on on my emulator (pixel 5 api 31) if you do a swipeLeft you actually go inbetween the third and fourth card so the nama showing is from the fourth card "Nox" not the third card "Frankie" So instead of

fun `horizontal_scrolling`() {
    onView(withId(R.id.horizontal_recycler_view))
        .perform(swipeLeft())
    onView(withText("Nox")).check(matches(isDisplayed()))
}

it should be

fun `horizontal_scrolling`() {
    onView(withId(R.id.horizontal_recycler_view))
        .perform(swipeLeft())
    onView(withText("Nox")).check(matches(isDisplayed()))
}

Steps to reproduce?

1. Run the tests and you can see 4 failing ones.
