Question

我需要测试一些使用改造来调用某些远程API的方法。此方法从实用程序类内部调用静态方法，该实用程序类从firebase中检索字符串，如baseUrl和终结点。

这是在方法makeRequest中调用静态方法FirebaseManager.employeeURL的类

public  class EmployeeAPI extends DedalusHandlerApi<List<Employee>> {
    private String cf;

    public EmployeeAPI(String cf, DedalusApiCallbackListener<List<Employee>> listener) {
        super(listener);
        this.cf = cf;

        doRequest();
    }

    @NotNull
    @Override
    protected Call<List<Employee>> makeRequest() {
        String url = FirebaseManager.employeeURL(this.cf);
        return getApiServiceAuth().getEmployee(url);
    }
}

这是一个引起异常的测试类。

@PrepareForTest(FirebaseManager::class)
@RunWith(PowerMockRunner::class)
@PowerMockIgnore("*")
class WSManagerTest {

private val mockWebServer = MockWebServer()

@Before
fun init() {
    PowerMockito.mockStatic(FirebaseManager::class.java)
    PowerMockito.`when`(FirebaseManager.baseURL()).thenReturn("")
    PowerMockito.`when`(FirebaseManager.loginURL()).thenReturn("")

    mockWebServer.start()
}

这是个例外

和FirebaseManager类

public class FirebaseManager {

private static BaseApplication baseApplication;

private static String getValue(String key) {
    if (baseApplication == null) baseApplication = BaseApplication.getInstance();

    return baseApplication.getFirebaseRemoteConfig().getString(key);
}

public static String baseURL() {
    return getValue("WS_BASE_URL");
}

public static String loginURL() {
    return getValue("WS_API_LOGIN");
}

public static String employeeURL(String cf) {
    return String.format("%s/%s",
            getValue("WS_API_EMPLOYEE"),
            cf
    );
}
}

我不明白我什么时候错了。

有人可以帮助我吗？非常感谢。

PowerMockito不模拟静态类
