C++ How do i run makefile output - unit-testing

Question

C++ How do i run makefile output
Below is my MakeFile, I want to ask how do i run my unitTest.cpp, as because when i MakeFile with NetBean, using the MakeFile below, main.exe is actually the main.cpp output
BUT I want to run the output of unitTest.cpp
How do i run unitTest.cpp
# ExampleTests Project
SRCS = main.cpp currencyConverter.cpp unitTest.cpp
HDRS = currencyConverter.h unitTest.h
PROJ = main
# Remaining lines shouldn't need changing
# Here's what they do:
# - rebuild if any header file or this Makefile changes
# - include CppUnit as dynamic library
# - search /opt/local for MacPorts
# - generate .exe files for Windows
# - add -enable-auto-import flag for Cygwin only
CC = g++
OBJS = $(SRCS:.cpp=.o)
APP = $(PROJ).exe
CFLAGS = -c -g -Wall -I/opt/local/include
ifeq (,$(findstring CYGWIN,$(shell uname)))
LDFLAGS = -L/opt/local/lib
else
LDFLAGS = -L/opt/local/lib -enable-auto-import
endif
LIBS = -lcppunit -ldl
all: $(APP)
$(APP): $(OBJS)
$(CC) $(LDFLAGS) $(OBJS) -o $(APP) $(LIBS)
%.o: %.cpp $(HDRS)
$(CC) $(CFLAGS) $< -o $#
clean:
rm -f *.o $(APP)
Below is my unitTest.cpp
#include "unitTest.h"
#include "currencyConverter.h"
CPPUNIT_TEST_SUITE_REGISTRATION(unitTest);
unitTest::unitTest() {
}
unitTest::~unitTest() {
}
void unitTest::setUp() {
}
void unitTest::tearDown() {
}
void stringToUpper(string&);
void unitTest::testStringLowerToUpper()
{
string str = "ILOVECPLUSPLUS";
string str2 = "IloveCplusplus";
cout << "\nChecking if string 1 '" << str << "' equals string 2 '" << str2 << "'";
CPPUNIT_ASSERT_EQUAL(str,str2);
//this part i will use my stringToUpperFunction to test.
currencyConverter c;
c.stringToUpper(str2);
cout << "\nChecking if string 1 '" << str << "' equals string 2 '" << str2 << "'";
CPPUNIT_ASSERT_EQUAL(str,str2);
}

Add another target (e.g. testrunner.exe) dependent on the .cpp files you want to test + your testsuite .cpp files + another .cpp file that consitutes the main() for your testrunner application to your make file. Having this you can add another target test, dependent on testrunner.exe that just calls the testrunner.exe executable.
