CTest 簡介

一、初識CTest

CTest是CMake集成的一個測試工具，在使用CMakeLists.txt文件編譯工程的時候，CTest會自動configure、build、test和展現測試結果

CTest有兩個模式：

• 模式一： 使用CMake configure 和 build工程，在CMakeLists.txt文件中，使用特殊的命令去創建tests。CTest用來執行那些測試

• 模式二： 使用CTest來執行一個script(這個script的語法必須和CMakeLists.txt相同)，去控制整個程序的輸出結果

二、使用方法

目前我們在工程中這樣構建單元測試

project
 |--------include
 |
 |--------src
 |
 |-----------test
 |       |---CMakeLists.txt
 |
 |--------CMakeLists.txt

1. 在外面的CMakeLists.txt中我們這樣寫

cmake_minimum_required(VERSION 2.8)
project(test)
....
add_subdirectory(test)
enable_testing()
add_test(NAME mytest COMMAND Test)

2. 在test/CMakeLists.txt中寫你的測試需要的即可（可以如下面那樣寫）

三、完整的簡單測試工程

include

  
    //sqr.h
#ifndef SQR_H_
#define SQR_H_

double sqr(double);

#endif

---

src

  
  //sqr.cpp
  #include "sqr.h"
double sqr(double x) {
 return x * x;
 }
//main.cpp
 int main()
 {
 return 0;
 }
 

---

test

  
//test.cpp
#include "sqr.h"
#define BOOST_TEST_MODULE SqrTests
#include 
   
   
   
            
            
BOOST_AUTO_TEST_CASE(FailTest)
 {
 BOOST_CHECK_EQUAL(5, sqr(2));
 }
 
            
BOOST_AUTO_TEST_CASE(PassTest)
 {
 BOOST_CHECK_EQUAL(4, sqr(2));
 }
 
            
//CMakeLists.txt
 find_package(Boost COMPONENTS system filesystem unit_test_framework REQUIRED)
 
            
include_directories(include ${Boost_INCLUDE_DIRS}/boost)
 
            
add_definitions(-DBOOST_TEST_DYN_LINK -g)
 add_executable(Test test.cpp)
 
            
target_link_libraries(Test sqr ${Boost_FILESYSTEM_LIBRARY}
 ${Boost_SYSTEM_LIBRARY}
 ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})
 
            
message(WARNING ${Boost_FILESYSTEM_LIBRARY})
 message(WARNING ${Boost_SYSTEM_LIBRARY})
 message(WARNING ${Boost_UNIT_TEST_FRAMEWORK_LIBRARY})
 
 
           

---

CMakeLists.txt

  
cmake_minimum_required(VERSION 2.8)
project(test)
include_directories(include)
 add_library(sqr STATIC src/sqr.cpp)
add_executable(demo src/main.cpp)
 target_link_libraries(demo sqr)
add_subdirectory(test)
 enable_testing()
 add_test(NAME mytest COMMAND Test)
