我试图为我的android项目实现检测测试。在我的主要项目中,我使用了 Dagger 和翻新版,并从我的模块中提供了翻新版。
这是我提供改造的模块:
@Module
public class NetModule {
@Provides
@Singleton
OkHttpClient.Builder provideOkHttpClientBuilder(){
OkHttpClient.Builder okHttp = new OkHttpClient.Builder();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
NoCacheInterceptor noCacheInterceptor = new NoCacheInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
if (!okHttp.interceptors().contains(interceptor))
okHttp.addInterceptor(interceptor);
if (!okHttp.interceptors().contains(noCacheInterceptor))
okHttp.addInterceptor(noCacheInterceptor);
return okHttp;
}
@Provides
Retrofit provideRetrofit(OkHttpClient.Builder httpClient){
return new Retrofit.Builder()
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(Constant.BASE_URL)
.client(httpClient.build()).build();
}
}
然后,在我的androidTest文件夹中,我创建了TestModule来对MockWebServer进行改造,如下所示:
@Module
public class TestNetModule {
private final MockWebServer mockWebServer;
public TestNetModule() {
mockWebServer = new MockWebServer();
}
@Provides
@Singleton
MockWebServer providerMockWebServer() {
return new MockWebServer();
}
@Provides
@Singleton
OkHttpClient.Builder provideOkHttpClientBuilder(){
OkHttpClient.Builder okHttp = new OkHttpClient.Builder();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
NoCacheInterceptor noCacheInterceptor = new NoCacheInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
if (!okHttp.interceptors().contains(interceptor))
okHttp.addInterceptor(interceptor);
if (!okHttp.interceptors().contains(noCacheInterceptor))
okHttp.addInterceptor(noCacheInterceptor);
return okHttp;
}
@Provides
Retrofit.Builder provideRetrofitBuilder(OkHttpClient.Builder httpClient, MockWebServer mockWebServer){
return new Retrofit.Builder()
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(mockWebServer.url("/").toString())
.client(httpClient.build()).build();
}
}
当我运行测试时,我总是在
android.os.NetworkOnMainThreadException
处收到错误.baseUrl(mockWebServer.url("/").toString())
。如何正确实现带有调试和 Dagger 的MockWebServer进行测试? 最佳答案
调用mockWebServer.url("/")
将启动服务器,这是无法在主线程上完成的操作。
我这样解决了这个问题:
@Provides
@Singleton
MockWebServer providerMockWebServer() {
MockWebServer mockWebServer = new MockWebServer()
Thread thread = new Thread() {
@Override
public void run() {
try {
mockWebServer.start();
} catch (IOException e) {
e.printStackTrace();
}
}
};
thread.start();
return mockWebServer;
}
