Testing Database with QTest

Peggy

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.

I would recomend you have a look at -> voidrealms.com

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. :(

Did u read chapter 16: Unit Testing in the Book: Foundations of Qt Development ?

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?

Peggy

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.
