任何人都知道错误是什么意思?或者也许错过了什么?
试图从这个样本开始,
添加了依赖项:testImplementation 'com.squareup.okhttp3:mockwebserver:3.11.0'
代码只是findMessage_receivesAScriptedResponseFromMockBackend
在 AndroidStudio 的示例单元测试中添加了一个 @Test:
public class ExampleUnitTest {
@Test
public void addition_isCorrect() {
assertEquals(4, 2 + 2);
}
///
@Rule
public MockWebServer mockBackend = new MockWebServer();
private MessagesApi mockApi() {
return new MessagesApi.Builder()
.baseUrl(mockBackend.url("/").toString())
.build();
}
@Test
public void builder_returnsInstance() {
final MessagesApi messagesApi = new MessagesApi.Builder()
.baseUrl("http://localhost:8888")
.build();
assertNotNull(messagesApi);
}
@Test
public void findMessage_receivesAScriptedResponseFromMockBackend() throws IOException {
mockBackend.enqueue(
new MockResponse()
.setBody("{\"text\":\"hello!\"}")
.setResponseCode(200)
.addHeader("Content-Type", "application/json;charset=utf-8")
);
final Response<Message> response = mockApi().findMessage("123").execute();
assertTrue((response.code()) == (200));
assertTrue((response.headers().get("Content-Type")).contains("application/json"));
final ResponseBody rawResponseBody = response.raw().body();
assertTrue((rawResponseBody.contentType().type()).equals("application"));
assertTrue((rawResponseBody.contentType().subtype()).equals("json"));
}
public class Message {
public String text;
}
public interface MessagesApi {
@GET("/message")
Call<Message> findMessage(@Query("query") String keyword);
/** Convenient builder for MessagesApi */
class Builder {
private String baseUrl;
public Builder() {}
public Builder baseUrl(String baseUrl) {
this.baseUrl = baseUrl;
return this;
}
public MessagesApi build() {
return new Retrofit.Builder()
.client(new OkHttpClient.Builder().build())
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(baseUrl)
.build()
.create(MessagesApi.class);
}
}
}
}
运行测试时显示错误:
