私はログインフラグメントを持っています。ユーザーが資格情報を入力すると、ユーザーはボタンをクリックして新しいアクティビティを開始します。ここにコードがあります。ShadowIntentがnull - Robolectric 3.0
public class LoginFragment extends Fragment {
Button loginButton;
EditText etName,etPass;
String login_name;
String login_pass;
private SessionManager session;
TextView forgotPassBtn;
public LoginFragment() {
// 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_login, container, false);
Toolbar myToolbar = (Toolbar) v.findViewById(R.id.toolbar);
((AppCompatActivity)getActivity()).setSupportActionBar(myToolbar);
setHasOptionsMenu(true);
etName = (EditText)v.findViewById(R.id.user_name);
etPass = (EditText)v.findViewById(R.id.user_pass);
loginButton = (Button) v.findViewById(R.id.loginButton);
login_name = etName.getText().toString();
login_pass = etName.getText().toString();
forgotPassBtn = (TextView) v.findViewById(R.id.forgotPass);
session = new SessionManager(getActivity());
if (session.isLoggedIn()) {
// User is already logged in. Take him to main activity
Intent intent = new Intent(getActivity(), Welcome.class);
startActivity(intent);
getActivity().finish();
}
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
login_name = etName.getText().toString();
login_pass = etPass.getText().toString();
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(getActivity());
SharedPreferences.Editor editor = settings.edit();
if(login_name.isEmpty() && login_pass.isEmpty()) {
Toast.makeText(getActivity(),"Username η κωδικός είναι κενό",Toast.LENGTH_SHORT).show();
}else {
editor.putString("id", "");
editor.putString("user_name", login_name);
editor.putString("user_pass", login_pass);
editor.commit();
loginUser(login_name, login_pass);
}
}
});
return v;
}
private void loginUser(final String userName,
final String password) {
/*
Tag used to cancel the request
HttpsTrustManager.sssMethod();
*/
String tag_string_req = "req_register";
StringRequest strReq = new StringRequest(Request.Method.POST,
Config.URL_LOGIN, 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")) {
session.setLogin(true);
Toast.makeText(getActivity(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
startActivity(Welcome.newIntent(getActivity()));
}
else if (jsonObject.getString("result").equals("fail")) {
Toast.makeText(getActivity(),jsonObject.getString("message"), Toast.LENGTH_LONG).show();
}
}catch(JSONException e){
e.printStackTrace();
}
// Launch login activity
//Toast.makeText(getApplicationContext(), "User successfully registered. Try login now!", Toast.LENGTH_LONG).show();
}
}, 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("user_name", userName);
params.put("user_pass", password);
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
}
}
新しい活動は、私はそれをテストしたようなコードは、正常に動作し
ここ
if (jsonObject.getString("result").equals("success")) {
session.setLogin(true);
Toast.makeText(getActivity(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
startActivity(Welcome.newIntent(getActivity()));
}
else if (jsonObject.getString("result").equals("fail")) {
Toast.makeText(getActivity(),jsonObject.getString("message"), Toast.LENGTH_LONG).show();
}
@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,sdk = 21)
public class LoginFragmentTest {
MainActivity activity;
Button loginButton;
@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();
ShadowActivity shadowActivity = shadowOf(activity);
Intent intent = shadowActivity.getNextStartedActivity();
ShadowIntent shadowIntent = shadowOf(intent);
//assertEquals(shadowIntent.getComponent().getClassName(),Welcome.class.getName());
}
}
テスト
loginFragmentShouldNotBeNull
shouldHaveUserNameEntry
shouldHavePasswordEntry
が渡されます。
しかし、私はここで
shouldHaveLoginButton
と例外を得ることである：
