Qt Quick Test 是用于 QML 应用程序的单元测试框架。测试用例被编写成 JavaScript 函数在 TestCase 类型:
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") } }
函数名称开头采用
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.
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
选项。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
