Я создал приложение для Android, в котором есть EditText и пароль EditText для входа в систему с условием, что если оба содержимого в EditText и пароль EditText для входа в систему совпадают, тогда его true, иначе false.Как проверить это с помощью Espresso Unit Testing
Я использовал приведенный ниже код.
@Test
public void validLogin() {
onView(withId(R.id.edtUserId))
.perform(typeText(mStringToBetyped), closeSoftKeyboard());
onView(withId(R.id.edtPass))
.perform(typeText(mValidPass), closeSoftKeyboard());
onView(withId(R.id.loginBtn)).perform(click());
// onView(allOf(withId(R.id.edtUserId))).check(matches(withText(String.valueOf(allOf(withId(R.id.edtPass))))));
onView(withId(R.id.edtUserId)).check(matches(isEditTextValueEqualTo(R.id.edtPass, mStringToBetyped)));
/* onView(allOf(withId(R.id.edtUserId)))
.check(matches(withText(String.valueOf(withId(R.id.edtPass)))));*/
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
Matcher<View> isEditTextValueEqualTo(final int viewId, final String content) {
return new TypeSafeMatcher<View>() {
@Override
public void describeTo(Description description) {
description.appendText("Match Edit Text Value with View ID Value : : " + content);
}
@Override
public boolean matchesSafely(View view) {
if (view != null) {
String editTextValue = ((EditText) view.findViewById(viewId)).getText().toString();
if (editTextValue.equalsIgnoreCase(content)) {
return true;
}
}
return false;
}
};
}
Но это дает мне ошибку для Matcher, как показано ниже
java.lang.NullPointerException: Attempt to invoke virtual method 'android.text.Editable android.widget.EditText.getText()' on a null object reference
