我尝试使用MockWebServer运行测试。
我想使用模拟响应进行 UI 测试,因此我可以测试有效\无效的 UI 更改,例如登录,或在登录 API 中显示错误。
但是,每次运行代码时,我都会遇到以下异常:
java.lang.IllegalStateException: start() already called
代码:
@RunWith(AndroidJUnit4.class)
public class UITestPlayground {
String testUrl = "http://testurl.com/";
MockWebServer server = new MockWebServer();
@Rule
public IntentsTestRule<LoginActivity> mIntentsRule = new IntentsTestRule<>(LoginActivity.class);
@Before
public void beforeHelper() throws IOException {
TestHelper.removeUserAndTokenIfAny(mIntentsRule.getActivity());
URLS.baseUrl = testUrl;
server.url(URLS.baseUrl);
//try to shutting down the server JUT IN CASE...
server.shutdown();
server.start();
}
@After
public void afterHelper() throws IOException {
server.shutdown();
}
@Test
public void invalidLoginDueNotValidJSONResponse() {
server.enqueue(new MockResponse().setBody("Something not valid JSON response"));
String emailToBeTyped = "tester@tester.com";
String passToBeTyped = "passtest";
ViewActions.closeSoftKeyboard();
// Type text and then press the button.
onView(withId(R.id.login_email_edit)).perform(typeText(emailToBeTyped));
ViewActions.closeSoftKeyboard();
onView(withId(R.id.login_pass_edit)).perform(typeText(passToBeTyped));
ViewActions.closeSoftKeyboard();
onView(withId(R.id.log_in_btn)).perform(click());
//TODO: check on valid error message appearing
}
}
我究竟做错了什么?.start() 只调用一次,我什至 .shutdown()以防万一......我不明白它怎么会调用不止一次。
提前致谢。
