我的应用程序中有两个片段。我想测试每一个中的所有视图。
所以这是第一个片段的代码。
@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,sdk = 21)
public class LoginFragmentTest {
MainActivity activity;
Button loginButton;
Welcome welcomeActivity;
@Before
public void setUp() throws Exception {
activity = Robolectric.setupActivity(MainActivity.class);
loginButton = getButton(activity,R.id.loginButton);
}
@Test
public void loginFragmentShouldNotBeNull(){
LoginFragment loginFragment = new LoginFragment();
startFragment(loginFragment, AppCompatActivity.class);
assertNotNull(loginFragment);
}
@Test
public void shouldHaveUserNameEntry() throws Exception{
EditText nameEntry = getEditText(activity,R.id.user_name);
assertViewIsVisible(nameEntry);
}
@Test
public void shouldHavePasswordEntry() throws Exception
{
EditText passEntry = getEditText(activity,R.id.user_pass);
assertViewIsVisible(passEntry);
}
@Test
public void shouldHaveLoginButton() throws Exception{
assertNotNull(loginButton);
assertViewIsVisible(loginButton);
}
@Test
public void shouldStartNewActivityWhenLoginButtonClicked() throws Exception
{
loginButton.performClick();
Intent intent = new Intent(Intent.ACTION_VIEW);
welcomeActivity = Robolectric.buildActivity(Welcome.class).withIntent(intent).create().get();
}
}
所有测试都通过。现在我将对第二个片段做同样的事情。
@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,sdk = 21)
public class RegisterFragmentTest {
MainActivity activity;
Button loginButton;
Welcome welcomeActivity;
EditText emailEntry;
@Before
public void setUp() throws Exception {
activity = Robolectric.setupActivity(MainActivity.class);
loginButton = getButton(activity,R.id.registerBtn);
emailEntry = getEditText(activity,R.id.email);
}
@Test
public void registerFragmentShouldNotBeNull(){
RegisterFragment registerFragment = new RegisterFragment();
startFragment(registerFragment, AppCompatActivity.class);
assertNotNull(registerFragment);
}
@Test
public void shouldHaveEmailEntry(){
assertViewIsVisible(emailEntry);
}
然而测试shouldHaveEmailEntry没有通过！

assertViewIsVisible（...）方法来自这个类。
public class Assert {
public static void assertViewIsVisible(View view){
assertNotNull(view);
assertThat(view.getVisibility(),equalTo(View.VISIBLE));
}
}
这是如何附加我的碎片。
public class MainActivity extends AppCompatActivity {
public static final String LOGIN_FRAGMENT = "LOGIN_FRAGMENT";
public static final String REGISTER_FRAGMENT = "REGISTER_FRAGMENT";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setTitle(R.string.login_toolbar_title);
LoginFragment loginFragment = new LoginFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(android.R.id.content,loginFragment,LOGIN_FRAGMENT);
fragmentTransaction.commit();
}
public void userReg(View view){
RegisterFragment regFragment = new RegisterFragment();
FragmentManager fragmentManager1 = getSupportFragmentManager();
FragmentTransaction fragmentTransaction1 = fragmentManager1.beginTransaction();
fragmentTransaction1.addToBackStack("added");
fragmentTransaction1.replace(android.R.id.content,regFragment,REGISTER_FRAGMENT);
fragmentTransaction1.commit();
}
}
我的RegisterFragment如下所示。
public class RegisterFragment extends Fragment {
private SessionManager session;
EditText etEmail, etUsername, etPassword,etConfirmPassword;
String email, userName, userPass,confirmPassword;
Button registerButton;
SqliteHandler sql;
public RegisterFragment() {
// Required empty public constructor
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_register, container, false);
Toolbar myToolbar = (Toolbar) v.findViewById(R.id.toolbar);
((AppCompatActivity)getActivity()).setSupportActionBar(myToolbar);
setHasOptionsMenu(true);
etEmail = (EditText)v.findViewById(R.id.email);
etUsername = (EditText)v.findViewById(R.id.user_name);
etPassword = (EditText)v.findViewById(R.id.user_pass);
etConfirmPassword = (EditText)v.findViewById(R.id.confirm_pass);
registerButton = (Button)v.findViewById(R.id.registerBtn);
session = new SessionManager(getActivity());
if (session.isLoggedIn()) {
// User ites already logged in. Take him to main activity
Intent intent = new Intent(getActivity(), Welcome.class);
startActivity(intent);
}
registerButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
email = etEmail.getText().toString();
userName = etUsername.getText().toString();
userPass = etPassword.getText().toString();
confirmPassword = etConfirmPassword.getText().toString();
if(userPass.equals(confirmPassword)){
registerUser(email, userName, userPass, confirmPassword);
getUserId();
}else{
Toast.makeText(getActivity(),"Passwords don't match",Toast.LENGTH_SHORT).show();
}
}
});
return v;
}
private void registerUser(final String email, final String userName,
final String password,final String confirmPassword) {
String tag_string_req = "req_register";
StringRequest strReq = new StringRequest(Request.Method.POST,
Config.URL_REGISTER, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.d("Response", "Register Response: " + response.toString());
try {
JSONObject jsonObject = new JSONObject(response);
if (jsonObject.getString("result").equals("success")) {
Toast.makeText(getActivity(),jsonObject.getString("message"), Toast.LENGTH_LONG).show();
//int id = jsonObject.getInt("message");
//Log.d("Theo", id);
//$don = array('result' =>"success","message"=>mysqli_insert_id($con));
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getActivity());
SharedPreferences.Editor editor = settings.edit();
//editor.putString("id", String.valueOf(id));
editor.putString("email", email);
editor.putString("user_name", userName);
editor.putString("user_pass", password);
editor.putString("confirm_pass", confirmPassword);
editor.commit();
}
else if (jsonObject.getString("result").equals("fail")) {
Toast.makeText(getActivity(),jsonObject.getString("message"), Toast.LENGTH_LONG).show();
}
}catch(JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("Error", "Registration Error: " + error.getMessage());
Toast.makeText(getActivity(),
error.getMessage(), Toast.LENGTH_LONG).show();
}
}) {
@Override
protected Map<String, String> getParams() {
// Posting params to register url
Map<String, String> params = new HashMap<String, String>();
params.put("id", "");
params.put("email", email);
params.put("user_name", userName);
params.put("user_pass", password);
params.put("confirm_pass", confirmPassword);
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
}
public void getUserId(){
JsonArrayRequest jsonObjReq = new JsonArrayRequest(Request.Method.GET,
URL.GET_PLAYER_ID,
new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
Log.d("TAG", response.toString());
try {
for(int i = 0; i<response.length(); i++){
JSONObject jsonObject = response.getJSONObject(i);
int userId = jsonObject.getInt("id");
Log.v("Theo", String.valueOf(userId));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq);
}
}
为什么我的junit没有通过的任何想法？
谢谢，

答案 0 :(得分：0)
第一个测试类启动MainActivity并进行一些测试。第二个测试类再次测试MainActivity。这两个活动都是使用LoginFragment启动的。
我猜你错过了userReg(View view)来启动RegFragment的电话。
您的测试方法*FragmentShouldNotBeNull没有多大意义，因为它们可以简化为：
RegisterFragment registerFragment = new RegisterFragment();
assertNotNull(registerFragment);
Robolectric不支持从现有活动开始新活动。它捕获所有意图并使它们可用但不执行它们。因此，跟随线在robolectric中没有实际效果。
if (session.isLoggedIn()) {
...
startActivity(intent);
}
