如何模拟参数请求单元测试谷歌云功能?

Question

我试图实现的是我的GCP函数的单元测试。我想模拟请求参数来测试我的函数怎么做呢?

这是我的GCP函数:

@Override
public void service(HttpRequest request, HttpResponse response)
throws IOException {
String name = request.getFirstQueryParameter("name").orElse("world");
try {
JsonElement requestParsed = gson.fromJson(request.getReader(), JsonElement.class);
JsonObject requestJson = null;
if (requestParsed != null && requestParsed.isJsonObject()) {
requestJson = requestParsed.getAsJsonObject();
}
if (requestJson != null && requestJson.has("name")) {
name = requestJson.get("name").getAsString();
}
} catch (JsonParseException e) {
logger.severe("Error parsing JSON: " + e.getMessage());
}
var writer = new PrintWriter(response.getWriter());
writer.printf("Hello %s!", name);
}

这是我的测试:

public class HelloHttpTest {
@Mock private HttpRequest request;
@Mock private HttpResponse response;
private BufferedWriter writerOut;
private StringWriter responseOut;
private static final Gson gson = new Gson();
@BeforeEach
public void beforeTest() throws IOException {
MockitoAnnotations.initMocks(this);
BufferedReader reader = new BufferedReader(new StringReader(""));
when(request.getReader()).thenReturn(reader);
responseOut = new StringWriter();
writerOut = new BufferedWriter(responseOut);
when(response.getWriter()).thenReturn(writerOut);
}
@Test
public void helloHttp_noParamsGet() throws IOException {
new HelloHttp().service(request, response);
writerOut.flush();
Assertions.assertEquals(responseOut.toString(),"Hello world!");
}
}

我想测试这条线name = requestJson.get("name").getAsString();是否工作。我如何用name参数发出假请求，而我的GCP将得到它?

试试下面的

BufferedReader reader = new BufferedReader(new StringReader("{"name":"world"}"));
