Testable is an utility library to enhance the function of the two testing frameworks offered by Qt: QTest for C++ and Qt Quick Test for QML.
Features:
- Support to run tests from mutiple QObjects
- Support to run QTest (C++) and Quick Tests (QML) in a same project
- Run specific test case / test object by command line and autotests plugin
- Setup custom property and image provider for Qt Quick Test by using engine hook function
- Utilities to search QQuickItem from Repeater/Flickable/ListView/GridView
Classes
- TestRunner - Multiple test objects runner
- Automator - Automator provides an interface to manipulate UI object loaded by QQmlApplicationEngine
qpm install com.github.benlau.testable
#include <TestRunner>
int main(int argc, char *argv[])
{
QGuiApplication app(argc,argv);
TestRunner runner;
runner.add<DummyTests1>(); // Run tests in DummyTest1 QObject
runner.add<DummyTests2>(); // Run tests in DummyTest2 QObject
// Run Qt Quick Test in SRCDIR. It will scan all qml file begin with tst_
runner.add(QString(SRCDIR));
runner.addImportPath("qrc:///");
runner.setEngineHook([](QQmlEngine* engine) {
engine->rootContext->setContextProperty("MyCustomProperty", new QObject());
});
bool error = runner.exec(app.arguments());
if (!error) {
qWarning() << "All test cases passed!";
}
return error;
}
Exampls are available at examples folder.

Qt Creator could not detect the tests written by Testable automatically. And therefore it will show nothing in the "Tests" panel and you can't trigger test via Autotests plugin.
To make it work, you have to declare the test object explicitly .
DummyTests1::DummyTests1(QObject *parent) : QObject(parent)
{
auto ref = [=]() {
QTest::qExec(this, 0, 0); // Autotest detect available test cases of a QObject by looking for "QTest::qExec" in source code
};
Q_UNUSED(ref);
}
The code does actually nothing but it is required for Autotest's parser to recognize the tests.
Autotests does not allow to declare more than a test within a source file. So you have to add this piece of code per source file.
For Qt Quick Tests, you need to declare QUICK_TEST_SOURCE_DIR in pro file:
project.pro file
DEFINES += QUICK_TEST_SOURCE_DIR=\\\"$$PWD\\\"
Then place QUICK_TEST_MAIN in your main.cpp explicitly.
#include <QtQuickTest/quicktest.h>
namespace AutoTestRegister {
QUICK_TEST_MAIN(QuickTests)
}
int main(int argc, char *argv[]) {
