Qt comes with a built-in unit testing module, which we can use by adding the testlib keyword to our project file (.pro):
QT += core gui testlib
After that, add the following header to our source code:
#include <QtTest/QtTest>
Then, we can start testing our code. We must declare our test functions as private slots. Other than that, the class must also inherit from the QOBject class. For example, I created two text functions called testString() and testGui(), like so:
private slots: void testString(); void testGui();
The function definitions look something like this:
void MainWindow::testString() { QString text = "Testing"; QVERIFY(text.toUpper() == "TESTING"); } void MainWindow::testGui() { QTest::keyClicks(ui->lineEdit, ...
