Although Catch allows you to group tests together as sections within a test case, it can still be convenient, sometimes, to group them using a more traditional test fixture. Catch fully supports this too. You define the test fixture as a simple structure:
class UniqueTestsFixture {
private:
static int uniqueID;
protected:
DBConnection conn;
public:
UniqueTestsFixture() : conn(DBConnection::createConnection("myDB")) {
}
protected:
int getID() {
return ++uniqueID;
}
};
int UniqueTestsFixture::uniqueID = 0;
TEST_CASE_METHOD(UniqueTestsFixture, "Create Employee/No Name", "[create]") {
REQUIRE_THROWS(conn.executeSQL("INSERT INTO employee (id, name) VALUES (?, ?)", getID(), ""));
}
TEST_CASE_METHOD(UniqueTestsFixture, "Create Employee/Normal", "[create]") {
REQUIRE(conn.executeSQL("INSERT INTO employee (id, name) VALUES (?, ?)", getID(), "Joe Bloggs"));
}
The two test cases here will create uniquely-named derived classes of UniqueTestsFixture and thus can access the getID()
protected method and conn
member variables. This ensures that both the test cases are able to create a DBConnection using the same method (DRY principle) and that any ID's created are unique such that the order that tests are executed does not matter.
