我通过扩展 @Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
Fragment selectedFragment = null;
switch (menuItem.getItemId()){
case R.id.navigation_map:
MapFragment mapFragment = new MapFragment();
mapFragment.show(getSupportFragmentManager(),"MapFragment");
break;
case R.id.navigation_search:
SearchFragment searchFragment = new SearchFragment();
searchFragment.show(getSupportFragmentManager(),"SearchFragment");
break;
}
return true;
}
};
来制作了一个自定义UI类EzCustomEditTextEmail，并在android（test）包中编写了相同的测试类（TextInputEditText）。我正在尝试实现Custom UI类的代码覆盖，并使用Mockito进行相同的处理。现在，我要写的是验证EmailUITest类的setMaxLines(1)方法中的inIt()行，并在EzCustomEditTextEmail的{{1}}获取 NullPointerException {1}}
