Boost test setup error: memory access violation - c++

Question

I am getting the above error while running the executable after compiling and running the following file.
#define BOOST_TEST_MAIN
#define BOOST_TEST_DYN_LINK
#include <iostream>
#include <boost/shared_ptr.hpp>
#include <boost/test/unit_test.hpp>
#include <boost/bind.hpp>
#include <boost/test/unit_test_log.hpp>
#include <boost/filesystem/fstream.hpp>
#include "index/DatabaseGroup.hpp"
using namespace boost::unit_test;
namespace indexing {
class ForwardDBTest {
/// A pointer to the database group object.
DatabaseGroup& databaseGroup;
std::string databaseName;
public:
~ForwardDBTest() {
}
;
ForwardDBTest(DatabaseGroup& databaseGroup_, std::string dbName) :
databaseGroup(databaseGroup_), databaseName(dbName) {
}
void boostTestCreateDB() {
databaseGroup.createDatabase(databaseName, databaseName);
}
};
class testSuites: public test_suite {
public:
testSuites() :
test_suite("test_suite") {
std::string db_location = "home/girijag/ripe/ripe_db";
std::cout << "hello" << std::endl;
int concurrency = 0;
std::string db_cache_policy = "AllMem";
boost::shared_ptr<DatabaseGroup> db = boost::shared_ptr<DatabaseGroup>(
new DatabaseGroup(db_location, concurrency, db_cache_policy));
std::string dbName = "DB1";
boost::shared_ptr<ForwardDBTest> instance(
new ForwardDBTest(*db, dbName));
test_case* boostTestCreateDB_test_case = BOOST_CLASS_TEST_CASE(
&ForwardDBTest::boostTestCreateDB, instance);
add(boostTestCreateDB_test_case);
}
~testSuites() {
}
;
};
test_suite* init_unit_test_suite(int argc, char** argv) {
test_suite* suite(BOOST_TEST_SUITE("Master Suite"));
suite->add(new testSuites());
return suite;
}
}'
Please let me know how should i resolve this?
i am getting errors as below:-
Test setup error: memory access violation at address: 0x00000021: no mapping at fault address
I have been struggling from past 2 days to figure out whats my issue

There are a number of disturbing things in the code, and some formatting seems have to been lost when posting the question, otherwise there is no chance it compiles. (For example, }’ ?!)
For starters, you shouldn’t place init_unit_test_suite(int, char**) in the indexing namespace, and subsequently there is no point in defining BOOST_TEST_MAIN - you will end up with multiple definition of the said init_unit_test_suite(int, char**) method.
In your case, the suite should be simply registered in the master test suite, there is no need to return a pointer to it from the method.
Here’s a minimal example that you can work with an extend for your purpose. It follows your structure, but omits non-relevant details:
#include <boost/test/included/unit_test.hpp>
#include <iostream>
using namespace boost::unit_test;
namespace indexing {
class ForwardDBTest {
public:
void boostTestCreateDB() { std::cout << __FUNCTION__ << std::endl; }
};
class TestSuite : public test_suite {
public:
TestSuite() : test_suite("test_suite") {
boost::shared_ptr<ForwardDBTest> instance(new ForwardDBTest);
add(BOOST_CLASS_TEST_CASE(&ForwardDBTest::boostTestCreateDB, instance));
}
};
} // namespace indexing
test_suite* init_unit_test_suite(int, char**) {
framework::master_test_suite().add(new indexing::TestSuite);
return 0;
}
/* Output:
Running 1 test case...
boostTestCreateDB
*** No errors detected
