I am working on this QT project and i am making test cases for my project. Here is a small test case
#include <QApplication>
#include <QPalette>
#include <QPixmap>
#include <QSplashScreen>
#include <qthread.h>
#define BOOST_TEST_MAIN
#include <boost/test/unit_test.hpp>
#include <boost/make_shared.hpp>
# include <boost/thread.hpp>
#include "MainWindow.h"
namespace
{
const std::string dbname = "Project.db";
struct SongFixture
{
SongFixture(const std::string &fixturePath)
{
// Create the Master file
Master::creator();
// Create/open file
std::pair<int, SQLiteDbPtr> result = open(
dbname, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, 0);
if (result.first != SQLITE_OK)
{
throw SQLiteError(result.first,
sqlite3_errmsg(result.second.get()));
}
SQLiteDbPtr &spDb = result.second;
// Execute all the SQL from the fixture file
execSQLFromFile(spDb, fixturePath);
}
};
std::auto_ptr<SongFixture> pf;
}
class I : public QThread
{
public:
static void sleep(unsigned long secs) {
QThread::sleep(secs);
}
};
void free_test_function()
{
BOOST_CHECK(true );
}
test_suite*
init_unit_test_suite(int argc, char *argv[])
{
// Create a fixture for the peer:
// Manage fixture creation manually instead of using
// BOOST_FIXTURE_TEST_CASE because the fixture depends on runtime args.
std::ostringstream fixturePathSS;
fixturePathSS << PROJECT_DIR << "/test/songs_fixture.sql";
std::string fixturePath = fixturePathSS.str();
pf.reset(new SongFixture(fixturePath));
QApplication app(argc, argv);
MainWindow window("artists");
window.show();
framework::master_test_suite().add( BOOST_TEST_CASE( &free_test_function ));
return app.exec();
}
Well i am getting any error
/usr/lib/gcc/x86_64-linux-gnu/4.6.1/../../../x86_64-linux-gnu/crt1.o:
In function _start': (.text+0x20): undefined reference tomain'
collect2: ld returned 1 exit status
pls help me you have a lead..thankz
I tired adding
#define BOOST_TEST_MAIN then i get
../test/UI/main.cpp: In function ‘boost::unit_test::test_suite* init_unit_test_suite(int, char**)’:
../test/UI/main.cpp:75:31: error: redefinition of ‘boost::unit_test::test_suite* init_unit_test_suite(int, char**)’
/usr/local/include/boost/test/unit_test_suite.hpp:223:1: error: ‘boost::unit_test::test_suite* init_unit_test_suite(int, char**)’ previously defined here
Well the program is working in Windows but in Linux the above mention problem is observed
