PySide6.QtQuickTest¶

Detailed Description¶

Qt Quick Test is a unit test framework for QML applications. Test cases are written as JavaScript functions within a QML TestCase type:

import QtQuick
import QtTest

TestCase {
    name: "MathTests"

    function test_math() {
        compare(2 + 2, 4, "2 + 2 = 4")
    }

    function test_fail() {
        compare(2 + 2, 5, "2 + 2 = 5")
    }
}

Functions whose names start with test_ are treated as test cases to be executed.

QML API¶

The QML types in Qt Quick Test are available through the QtTest import. To use the types, add the following import statement to your .qml file:

import QtTest

Running Tests¶

Test cases are launched by a harness that consists of the following code:

import sys
from PySide6.QtQuickTest import QUICK_TEST_MAIN

QUICK_TEST_MAIN("example", sys.argv)

Where “example” is the identifier to use to uniquely identify this set of tests.

Test execution can be controlled by a number of command line options (pass -h for help).

Executing Code Before QML Tests¶

To execute code before any of the QML tests are run, the QUICK_TEST_MAIN_WITH_SETUP() function can be used. This can be useful for setting context properties on the QML engine, amongst other things.
