Tag: espresso

I'm trying to write a test with Espresso for my SearchView.
Normally, the search works correctly, but when it is tested RecyclerView is not updated when writing text.

Here is my test method:

@Test
public void searchText () launches Throwable {
Fragment of MyFragment = activity.getActivity (). GetFragment ();
fragment.getPresenter (). isTesting ();
List < Product > data = new ArrayList < > ();

for (int i = 0; i <10; i ++) {
Product product = new product ();
String product_name = "Product" + i;
product.setProduct_name (product_name);

data.add (product);
}

runOnUiThread (new Runnable () {
@Cancel
public void run () {
fragment.showData (data);

}
});

ViewInteraction recycler = Espresso.onView (withId (R.id.my_recycler_view));

// check size
recycler.check (matches (recyclerViewSizeMatcher (10, null)));

onView (withId (R.id.search)). perform (click ());

onView (isAssignableFrom (EditText.class)). perform (typeText ("Product 1"), press Key (KeyEvent.KEYCODE_ENTER));

// check size
recycler.check (matches (recyclerViewSizeMatcher (1, null)));

}

Returns an error in the last line, when it verifies the size of the recyclerview:

androidx.test.espresso.base.DefaultFailureHandler $ AssertionFailedWithCauseError:
& # 39; with list size: 1 & # 39; does not match the selected view.

Expected: with list size: 1
