改造调用为空，而我 运行 测试 class.
编辑 2 APIClient.java:

在您的单元测试中，您正在调用 apiInterFace.requestLogin 到 return null:
when(apiInterFace.requestLogin(anyString(), any(), anyString())).thenReturn(null);
在LoginActivity.loginToServer中调用apiInterFace.requestLogin，其return用于调用enqueue函数：
Call<LoginSuccessRes> loginCall = apiInterFace.requestLogin(Constants.PLATFORM, loginReq, custId);
loginCall.enqueue(new Callback<LoginSuccessRes>() { ... }
因此，当您尝试在 loginCall 变量中的 Call<LoginSuccessRes> 的空实例上调用 enqueue 函数时，您会得到一个 NullPointerException。

编辑 1: 改造调用为空，而我 运行 测试 class.
编辑 2 APIClient.java:

在您的单元测试中，您正在调用 apiInterFace.requestLogin 到 return null:
when(apiInterFace.requestLogin(anyString(), any(), anyString())).thenReturn(null);
在LoginActivity.loginToServer中调用apiInterFace.requestLogin，其return用于调用enqueue函数：
Call<LoginSuccessRes> loginCall = apiInterFace.requestLogin(Constants.PLATFORM, loginReq, custId);
loginCall.enqueue(new Callback<LoginSuccessRes>() { ... }
因此，当您尝试在 loginCall 变量中的 Call<LoginSuccessRes> 的空实例上调用 enqueue 函数时，您会得到一个 NullPointerException。
