http://localhost:8080/

3. For create a new job is very simple.

 3.1. Click on ” New Job “


 3.2. Select the option , im my case I choose the “Build a free-style software project”


 3.3 Select the options , wirte scripts and save.

State Machine

Hi,

I am posting an example that demonstrates the use of QStateMachine.

A state machine with three states, state1, state2 and state3. The state machine is controlled by three QPushButton; when the button is clicked, the machine transitions to another state. Initially, the state machine is in state state1.

main.cpp

The Simple Test

I am learning a few of QtTest and I am showing the simple and little test  for QtDate . The test verify if  the date is valid and compare the actual date.

== test.cpp==

1 #include <QtTest>
2
3
4
5 class testDate: public QObject
6 {
7 Q_OBJECT
8
9 private slots:
10
11 void testValidity();
12 void testCurrentDate();
13
14 };
15
16 /* Here the test for verifying if the date is Valid, can you change the Day for plus 31 and the Mo nth plus 12 */
17 void testDate::testValidity()
18 {
19 QDate date (2009, 04, 33);
20 QVERIFY(date.isValid());
21 }
22
23
24 /* Here the Date is compared with the actual Date */
25 void testDate::testCurrentDate()
26 {
27
28 QDate date, date2;
29 date.setYMD(2009, 4, 22);
30 date2 = QDate::currentDate();
31 QCOMPARE(date, date2);
32 }
33
34
35
36
37 QTEST_MAIN(testDate);
38 #include “test1.moc”

QVERIFY ( condition )

The QVERIFY() macro checks whether the condition is true or not. If it is true, execution continues. If not, a failure is recorded in the test log and the test won’t be executed further.

QCOMPARE ( actual, expected )

The QCOMPARE macro compares an actual value to an expected value using the equals operator. If actual and expected are identical, execution continues. If not, a failure is recorded in the test log and the test won’t be executed further.
