单元测试工具CPPUnit在Windows平台下使用图形界面,操作非常直观;但在Unix平台下,就需要花点功夫配置一番:
1.下载文件:
本人使用的是cppunit-1.12.0.rar 版本,可以在以下地址下载(http://u.115.com/file/f6a03bec8)共享有效期有一个月,这软件在网上也好找。如以上地址过期,未找到合适版本,请留言联系;
2.不用安装,直接将cppunit解压到指定路径;
3.编写CPPUnit makefile, 需指定以下3中路径:
1.待测试代码路径;
2.CPPUNIT软件路径;
3.测试代码路径;
给出makefile范例:
CC = CC MV = mv CP = cp RM = rm CFLAGS = # Change It COLIN_HOME =/userhome/colin CPPUNIT_HOME = /userhome/colin/tools/cppunit-1.12.0 PROJECT_HOME = $(COLIN_HOME)/cl/src UNITTEST_HOME= $(COLIN_HOME)/cl/unittest ORALIB = -L$(ORACLE_HOME)/lib32 -lclntsh CPPUNITLIB = -L$(CPPUNIT_HOME)/lib -lcppunit ORAINC = -I$(ORACLE_HOME)/rdbms/demo -I$(ORACLE_HOME)/rdbms/public -I$(ORACLE_HOME)/precomp/public CXXFLAGS = -O2 -g #-Wall APPINC = -I$(PROJECT_HOME)\ -I$(CPPUNIT_HOME)/include \ -I$(UNITTEST_HOME) clOBJ=$(PROJECT_HOME)/common/Record.o \ $(PROJECT_HOME)/common/Recordset.o \ $(PROJECT_HOME)/common/DBHandler.o \ $(PROJECT_HOME)/common/DBHandlerImpl.o \ $(PROJECT_HOME)/common/LogMacros.o \ $(PROJECT_HOME)/common/DateTime.o \ $(PROJECT_HOME)/clTypeB/clTypeBHandler.o \ $(PROJECT_HOME)/clTypeB/clTypeBUpdate.o clTESTOBJ = $(UNITTEST_HOME)/clTypeBTest.o \ $(UNITTEST_HOME)/clTypeBUnitTest.o OBJS = $(clOBJ) $(clTESTOBJ) all: cltest cltest: $(OBJS) $(CC) -o $@ $(OBJS) $(CXXFLAGS) $(ORALIB) $(CPPUNITLIB) .SUFFIXES : .cpp .cpp.o : $(CC) $(CFLAGS) $(APPINC) $(ORAINC) -c -O $< -o $*.o .PHONY:clean clean: $(RM) $(OBJS)
4.在$(COLIN_HOME)/cl/unittest/编写测试代码,测试代码由两部分组成:
1.带主函数的文件,固定格式,不用修改:
#include <cppunit/extensions/HelperMacros.h> #include <cppunit/CompilerOutputter.h> #include <cppunit/extensions/TestFactoryRegistry.h> #include <cppunit/ui/text/TestRunner.h> int main(int argc, char* argv[]) { // Get the top level suite from the registry CppUnit::Test *suite = CppUnit::TestFactoryRegistry::getRegistry().makeTest(); // Adds the test to the list of test to run CppUnit::TextUi::TestRunner runner; runner.addTest( suite ); // Change the default outputter to a compiler error format outputter runner.setOutputter( new CppUnit::CompilerOutputter( &runner.result(), std::cerr ) ); // Run the tests. bool wasSucessful = runner.run(); // Return error code 1 if the one of test failed. return wasSucessful ? 0 : 1; }
2.单元测试类ClassSvrPluginTest:其中加入了一些宏,类似于MFC处理方式,按照例子相应的加入:
对于每个测试用例,可写成一个函数test1(),并加入到宏CPPUNIT_TEST()中:
ClassSvrPluginTest.h
#pragma once #include <cppunit/extensions/HelperMacros.h> using namespace std; class ClassSvrPluginTest :public CppUnit::TestFixture { CPPUNIT_TEST_SUITE(ClassSvrPluginTest); CPPUNIT_TEST(test1); CPPUNIT_TEST(test2); CPPUNIT_TEST_SUITE_END(); public: ClassSvrPluginTest(void); ~ClassSvrPluginTest(void); void test1(); void test2(); };
ClassSvrPluginTest.cpp
#include "ClassSvrPluginTest.h" CPPUNIT_TEST_SUITE_REGISTRATION(ClassSvrPluginTest); ClassSvrPluginTest::ClassSvrPluginTest(void) { } ClassSvrPluginTest::~ClassSvrPluginTest(void) { } void ClassSvrPluginTest::test1() { int i = -1; CPPUNIT_ASSERT_EQUAL(-1, i); } void ClassSvrPluginTest::test2() { int i = -1; CPPUNIT_ASSERT_EQUAL(-1, i); }
配置完毕,makefile生成文件可执行文件cltest即可进行测试。
当然,上述代码并没有实际的测试源代码,可以ClassSvrPluginTest.cpp中包含源代码的头,然后,生成对象,对其函数的返回值进行测试,cppunit 通过宏CPPUNIT_ASSERT_EQUAL(-1, i)来判断测试结果是否和预期相同。
