java - 如何对在 AndroidViewModel 类内部进行改造调用的方法进行单元测试？

Question

我想为通过进行改造调用来执行注册的方法编写单元测试，并且该方法位于 AndroidViewModel 类中。如何测试该方法？

public class SignUpViewModel extends AndroidViewModel {
    private final Context context;
    private LoadToast loadToast;

    public SignUpViewModel(@NonNull Application application, Context context) {
        super(application);
        this.context = context;
    }


    public void signUpRequest(final String userName, String userPassword, String userEmail, String firstName, String lastName, String securityQuestion, String securityAnswer) {
        JSONObject jsonObject = new JSONObject();
        JSONObject securityJsonObject = new JSONObject();
        loadToast = new LoadToast(context);
        loadToast.setText("Signing in");
        loadToast.show();
        try {

            jsonObject.put("identifier", userName);
            jsonObject.put("password", userPassword);
            jsonObject.put("email", userEmail);
            jsonObject.put("firstName", firstName);
            jsonObject.put("lastName", lastName);
            securityJsonObject.put("question", securityQuestion);
            securityJsonObject.put("answer", securityAnswer);
            jsonObject.put("securityQuestion",securityJsonObject);

        } catch (JSONException e) {
            e.printStackTrace();
        }

        APIService apiService = RetrofitClient.getAPIService();
        Call<String> signUpResponse = apiService.createUser(jsonObject.toString());
        signUpResponse.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response) {
                if (response.message().equals("timeout")) {
                    loadToast.error();
                    Toast.makeText(getApplication(), "Network Connection issues please try again", Toast.LENGTH_LONG).show();
                }
                if (response.code() == 200) {
                    loadToast.success();
                    Toast.makeText(getApplication(), "An activation link has been sent to your email. Follow it to activate your account.", Toast.LENGTH_LONG).show();
                    context.startActivity(new Intent(context, LogInActivity.class));
                } else if (response.code() == 409) {
                    loadToast.error();
                    Toast.makeText(getApplication(), "User With Same UserName already Exists", Toast.LENGTH_LONG).show();
                } else {
                    loadToast.error();
                    Toast.makeText(getApplication(), "Something went wrong please try again", Toast.LENGTH_LONG).show();
                }
            }

            @Override
            public void onFailure(Call<String> call, Throwable t) {
                loadToast.error();
                Toast.makeText(getApplication(), "" + t.getMessage(), Toast.LENGTH_SHORT).show();

            }
        });
    }


}

我的类看起来像这样，我想测试 signUpRequest 方法。我读了一些教程，但它们没有帮助。那么，我如何编写单元测试来测试我的方法？

根据清洁架构方法，您的 ViewModel 代码不得包含任何与框架相关的代码。尤其是上下文。您在改造中所做的所有这些工作都必须移至另一层。将此代码移动到 UseCase 或 Interactor 中并使用 Repository 模式。此链接可能会有所帮助:https://proandroiddev.com/how-to-implement-a-clean-architecture-on-android-2e5e8c8e81fe

良好的架构将使您的代码可测试。希望它会有所帮助:)
