    Hello,

    I would like to write some QTest for database class, like connecting to database, insert tables , data.... I am beginner in this field and don't have a clue how should I start with it. I read some articles which mostly were about testing GUI. But they did not help me so far. I appreciate someone who could give me further information.

        Suths thanks for the suggestion.
        But I still could not find QTest example. I know how to connect to database and get the query from but I don't know how am I supposed to write some QTest(UnitTest) for it. :(

            Not related to databases, but the same type of concepts apply to testing as with anything else. Take a look at the tests under

              Thank you MuhamedAuda for introducing the Book. I have read the UnitTest chapter. The first test I wrote is as following:

              @
              void TestDBMethods::testConnection(){

              QSqlDatabase db = QSqlDatabase::addDatabase("QMYSQL");
              db.setDatabaseName("test");
              db.setHostName("localhost");
              db.setUserName("************");
              db.setPassword("************");
              QVERIFY(db.isValid());
              QCOMPARE(db.isOpen(), true);
              

              }
              @

              in the normal case my connection will be established but in this case I got fail by QCOMPARE. Could anyone tell me where my error is?

              Question: what are the alternatives for testing the methods of another subproject in my test project?

                Ok I got my error.

                I have to write @QCOMPARE(db.open(), true)@

                But I still am looking forward to any suggestions that may help me to test the methoes of other subprojects in my test projects.
