Question

我正在尝试将Catch单元测试集成到我的项目中，但目前可用的

失败了

Catch v1.10.0
Generated: 2017-08-26 15:16:46.676990

示例：

test.cpp

#include "catch.hpp"

#define CATCH_CONFIG_MAIN


TEST_CASE("CATCH TEST"){
    REQUIRE(1 == 1);
}

g++ test.cpp -o test.exe -std=c++11

错误：

目前，您的程序没有private int Question_no=0; private Boolean Boolean_Var=false; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_question1); String[] Question_Array = getResources().getStringArray(R.array.Question1); TextView Questions = (TextView) findViewById(R.id.Question); Questions.setText(Question_Array[Question_no]); String[] Radio_Button1_Array = getResources().getStringArray(R.array.Option_1); RadioButton Radio_Button1 = (RadioButton) findViewById(R.id.radioButton1); Radio_Button1.setText(Radio_Button1_Array[Question_no]); String[] Radio_Button2_Array = getResources().getStringArray(R.array.Option_2); RadioButton Radio_Button2 = (RadioButton) findViewById(R.id.radioButton2); Radio_Button2.setText(Radio_Button2_Array[Question_no]); findViewById(R.id.MenuButton).setVisibility(View.INVISIBLE); findViewById(R.id.NextButton).setVisibility(View.INVISIBLE); } public void On_RadioButton1_Click (View view) { if (Boolean_Var == false) { String[] CorrectAns_Array = getResources().getStringArray(R.array.Answer1); String CorrectAns = CorrectAns_Array[Question_no]; String[] Answer_Array = getResources().getStringArray(R.array.Option_1); String Answer = Answer_Array[Question_no]; if (Answer.equals(CorrectAns)) { RadioButton Right_Ans = (RadioButton) findViewById(R.id.radioButton1); Right_Ans.setTextColor(Color.GREEN); AnswerSubmitted(); } else { RadioButton Wrong_Ans = (RadioButton) findViewById(R.id.radioButton1); Wrong_Ans.setTextColor(Color.RED);; GreenTick(); AnswerSubmitted(); } } Boolean_Var = true; } public void On_RadioButton2_Click(View view) { if(Boolean_Var==false) { String[] CorrectAns_Array = getResources().getStringArray(R.array.Answer1); String CorrectAns = CorrectAns_Array[Question_no]; String[] Answer_Array = getResources().getStringArray(R.array.Option_2); String Answer = Answer_Array[Question_no]; if(Answer.equals(CorrectAns)) { RadioButton Right_Ans = (RadioButton) findViewById(R.id.radioButton2); Right_Ans.setTextColor(Color.GREEN); } else { RadioButton Wrong_Ans = (RadioButton) findViewById(R.id.radioButton2); Wrong_Ans.setTextColor(Color.RED); GreenTick(); } } Boolean_Var=true; AnswerSubmitted(); } public void GreenTick() { String[] Answer1_Array = getResources().getStringArray(R.array.Option_1); String Answer1 = Answer1_Array[Question_no]; String[] Answer2_Array = getResources().getStringArray(R.array.Option_2); String Answer2 = Answer2_Array[Question_no]; String[] Answer3_Array = getResources().getStringArray(R.array.Option_3); String Answer3 = Answer3_Array[Question_no]; String[] The_CorrectAns_Array = getResources().getStringArray(R.array.Answer1); String The_CorrectAnsIs = The_CorrectAns_Array[Question_no]; if(The_CorrectAnsIs.equals(Answer1)) { Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton1); Option_with_CorrectAns.setTextColor(Color.GREEN); } else if(The_CorrectAnsIs.equals(Answer2)) { Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton2); Option_with_CorrectAns.setTextColor(Color.GREEN); } else if(The_CorrectAnsIs.equals(Answer3)) { Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton3); Option_with_CorrectAns.setTextColor(Color.GREEN); } else { Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton4); Option_with_CorrectAns.setTextColor(Color.GREEN); } } public void AnswerSubmitted() { findViewById(R.id.MenuButton).setVisibility(View.VISIBLE); findViewById(R.id.NextButton).setVisibility(View.VISIBLE); } }功能。如果编译它，链接器会抱怨缺少main函数。由于您使用catch框架编写单元测试，因此您希望该框架为您生成main函数。

catch框架查看是否定义了main，如果是，则为您生成CATCH_CONFIG_MAIN函数，该函数运行您定义的所有测试。由于编译是一个线性过程，因此宏main必须在之前定义，包括CATCH_CONFIG_MAIN。否则，库将永远不会“看到”此宏。
