Qt Quick Test Reference Documentation

介紹

Qt Quick Test 是用於 QML 應用程序的單元測試框架。測試用例被編寫成 JavaScript 函數在 TestCase 類型:

import QtQuick 2.3
import QtTest 1.0
TestCase {
    name: "MathTests"
    function test_math() {
        compare(2 + 2, 4, "2 + 2 = 4")
    }
    function test_fail() {
        compare(2 + 2, 5, "2 + 2 = 5")
    }
}
					

函數名稱開頭采用 test_ are treated as test cases to be executed. See the documentation for the TestCase and SignalSpy types for more information on writing test cases.

運行測試

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

#include <QtQuickTest/quicktest.h>
QUICK_TEST_MAIN(example)
					

Where "example" is the identifier to use to uniquely identify this set of tests. You should add CONFIG += qmltestcase . for example:

TEMPLATE = app
TARGET = tst_example
CONFIG += warn_on qmltestcase
SOURCES += tst_example.cpp
					

The test harness scans the specified source directory recursively for "tst_*.qml" files. If QUICK_TEST_SOURCE_DIR is not defined, then the current directory will be scanned when the harness is run. Other *.qml files may appear for auxillary QML components that are used by the test.

The -input command-line option can be set at runtime to run test cases from a different directory. This may be needed to run tests on a target device where the compiled-in directory name refers to a host. For example:

tst_example -input /mnt/SDCard/qmltests
					

It is also possible to run a single file using the -input 選項。例如:

tst_example -input data/test.qml
					
tst_example -input <full_path>/test.qml
					

注意: Specifying the full path to the qml test file is for example needed for shadow builds.

If your test case needs QML imports, then you can add them as -import options to the test program command-line.

If IMPORTPATH is specified in your .pro file, each import path added to IMPORTPATH will be passed as a command-line argument when the test is run using "make check":

IMPORTPATH += $$PWD/../imports/my_module1 $$PWD/../imports/my_module2
					

The -functions command-line option will return a list of the current tests functions. It is possible to run a single test function using the name of the test function as an argument. For example:

tst_example Test_Name::function1
					

The -help command-line option will return all the options available.

tst_example -help
