如何在Python中自动将几十个测试用例添加到测试套件中

我在不同的文件夹中有几十个测试用例。在根目录中有一个测试运行程序。

unittest\
  package1\
    test1.py
    test2.py
  package2\
    test3.py
    test4.py
  testrunner.py

目前我手动将四个测试用例添加到测试套件中

import unittest
from package1.test1 import Test1
from package1.test2 import Test2
from package2.test3 import Test3
from package2.test4 import Test4

suite = unittest.TestSuite()
suite.addTests(unittest.makeSuite(Test1))
suite.addTests(unittest.makeSuite(Test2))
suite.addTests(unittest.makeSuite(Test3))
suite.addTests(unittest.makeSuite(Test4))

result = unittest.TextTestRunner(verbosity=2).run(suite)
if not result.wasSuccessful():
  sys.exit(1)

如何让测试运行程序自动测试所有测试用例?例如:

for testCase in findTestCases():
  suite.addTests(testCase)

i have dozen of test cases in different folders. In the root directory there is a test runner.

unittest\
  package1\
    test1.py
    test2.py
  package2\
    test3.py
    test4.py
  testrunner.py

Currently I added the four test cases manually into a test suite

import unittest
from package1.test1 import Test1
from package1.test2 import Test2
from package2.test3 import Test3
from package2.test4 import Test4

suite = unittest.TestSuite()
suite.addTests(unittest.makeSuite(Test1))
suite.addTests(unittest.makeSuite(Test2))
suite.addTests(unittest.makeSuite(Test3))
suite.addTests(unittest.makeSuite(Test4))

result = unittest.TextTestRunner(verbosity=2).run(suite)
if not result.wasSuccessful():
  sys.exit(1)

How to let test runner test all test cases automatically? Such as:

for testCase in findTestCases():
  suite.addTests(testCase)

在我看来,您应该切换到 unittest2 或其他具有发现功能的测试框架。发现测试是一种非常明智的运行方式。

最知名的是:

例如,使用nosetest就足以从项目根目录运行nosetests,它将发现并运行所有它找到的单元测试。很简单。

还要注意,unittest2 将包含在 python 2.7 中(我猜会向后移植到 2.4)。

In my opinion you should switch to unittest2 or other test frameworks with discovery features. Discovery tests is a really sane way to run them.

Most known are:

For example with nosetest is sufficient to run nosetests from the project root directory and it will discover and run all the unit tests it find. Pretty simple.

Notice also that unittest2 will be included in python 2.7 (and backported till 2.4 I guess).

上面的模块很好,但是当尝试输入参数时,NoseTests 可能很有趣,而且这也更快并且很好地适合另一个模块。

import os, unittest

class Tests():   

    def suite(self): #Function stores all the modules to be tested


        modules_to_test = []
        test_dir = os.listdir('.')
        for test in test_dir:
            if test.startswith('test') and test.endswith('.py'):
                modules_to_test.append(test.rstrip('.py'))

        alltests = unittest.TestSuite()
        for module in map(__import__, modules_to_test):
            module.testvars = ["variables you want to pass through"]
            alltests.addTest(unittest.findTestCases(module))
        return alltests

if __name__ == '__main__':
    MyTests = Tests()
    unittest.main(defaultTest='MyTests.suite')

如果您想将结果添加到日志文件中,请在末尾添加以下内容:

if __name__ == '__main__':
    MyTests = Tests()
    log_file = 'log_file.txt'
    f = open(log_file, "w") 
    runner = unittest.TextTestRunner(f)
    unittest.main(defaultTest='MyTests.suite', testRunner=runner)

也在您正在测试的模块的底部放置如下代码:

class SomeTestSuite(unittest.TestSuite):

    # Tests to be tested by test suite
    def makeRemoveAudioSource():
        suite = unittest.TestSuite()
        suite.AddTest(TestSomething("TestSomeClass"))

        return suite

    def suite():
        return unittest.makeSuite(TestSomething)

if __name__ == '__main__':
    unittest.main()

The above modules are good but NoseTests can be funny when trying to enter in parameters and this is also faster and fit's into another module nicely.

import os, unittest

class Tests():   

    def suite(self): #Function stores all the modules to be tested


        modules_to_test = []
        test_dir = os.listdir('.')
        for test in test_dir:
            if test.startswith('test') and test.endswith('.py'):
                modules_to_test.append(test.rstrip('.py'))

        alltests = unittest.TestSuite()
        for module in map(__import__, modules_to_test):
            module.testvars = ["variables you want to pass through"]
            alltests.addTest(unittest.findTestCases(module))
        return alltests

if __name__ == '__main__':
    MyTests = Tests()
    unittest.main(defaultTest='MyTests.suite')

If you want to add results to a log file add this at the end instead:

if __name__ == '__main__':
    MyTests = Tests()
    log_file = 'log_file.txt'
    f = open(log_file, "w") 
    runner = unittest.TextTestRunner(f)
    unittest.main(defaultTest='MyTests.suite', testRunner=runner)

Also at the bottom of the modules you are testing place code like this:

class SomeTestSuite(unittest.TestSuite):

    # Tests to be tested by test suite
    def makeRemoveAudioSource():
        suite = unittest.TestSuite()
        suite.AddTest(TestSomething("TestSomeClass"))

        return suite

    def suite():
        return unittest.makeSuite(TestSomething)

if __name__ == '__main__':
    unittest.main()

我所做的是一个运行单独测试文件的包装器脚本:

主包装器 < code>run_tests.py

#!/usr/bin/env python3
# Usage: ./run_tests.py -h http://example.com/ tests/**/*.py
import sys, unittest, argparse, inspect, logging

if __name__ == '__main__':
    # Parse arguments.
    parser = argparse.ArgumentParser(add_help=False)
    parser.add_argument("-v", "--verbose",  action="store_true", dest="verbose",  help="increase output verbosity" )
    parser.add_argument("-d", "--debug",    action="store_true", dest="debug",    help="show debug messages" )
    parser.add_argument("-h", "--host",     action="store",      dest="host",     help="Destination host" )
    parser.add_argument('files', nargs='*')
    args = parser.parse_args()

    # Load files from the arguments.
    for filename in args.files:
        exec(open(filename).read())

    # See: http://codereview.stackexchange.com/q/88655/15346
    def make_suite(tc_class):
        testloader = unittest.TestLoader()
        testnames = testloader.getTestCaseNames(tc_class)
        suite = unittest.TestSuite()
        for name in testnames:
            suite.addTest(tc_class(name, cargs=args))
        return suite

    # Add all tests.
    alltests = unittest.TestSuite()
    for name, obj in inspect.getmembers(sys.modules[__name__]):
        if inspect.isclass(obj) and name.startswith("FooTest") and len(name) > len("FooTest"):
            alltests.addTest(make_suite(obj))

    # Run tests.
    result = unittest.TextTestRunner(verbosity=2).run(alltests)
    sys.exit(not result.wasSuccessful())

然后是另一个测试包装器:

class FooTest(unittest.TestCase):
    def __init__(self, *args, cargs=None, **kwargs):
        super().__init__(*args, **kwargs)
        self.vdisplay = Xvfb(width=1280, height=720)
        self.vdisplay.start()
        self.args=cargs
        self.log=logging

    def setUp(self):
        self.site = webdriver.Firefox()

    def kill(self):
        self.vdisplay.stop()

然后单独文件中的每个测试将如下所示:

import sys, os, unittest
from FooTest import FooTest

class FooTest1(FooTest):

    def test_homepage(self):
        self.site.get(self.base_url + "/")
        log.debug("Home page loaded.")

然后您可以轻松地从 shell 运行测试,例如:

$ ./run_tests.py -h http://example.com/ test1.py test2.py

您可以使用通配符指定特定文件中的所有文件目录,或使用新的通配选项 (**)以递归方式运行所有测试(通过 shopt -s globstar 启用)。

What I did is a wrapper script which running separate test files:

Main wrapper run_tests.py:

#!/usr/bin/env python3
# Usage: ./run_tests.py -h http://example.com/ tests/**/*.py
import sys, unittest, argparse, inspect, logging

if __name__ == '__main__':
    # Parse arguments.
    parser = argparse.ArgumentParser(add_help=False)
    parser.add_argument("-v", "--verbose",  action="store_true", dest="verbose",  help="increase output verbosity" )
    parser.add_argument("-d", "--debug",    action="store_true", dest="debug",    help="show debug messages" )
    parser.add_argument("-h", "--host",     action="store",      dest="host",     help="Destination host" )
    parser.add_argument('files', nargs='*')
    args = parser.parse_args()

    # Load files from the arguments.
    for filename in args.files:
        exec(open(filename).read())

    # See: http://codereview.stackexchange.com/q/88655/15346
    def make_suite(tc_class):
        testloader = unittest.TestLoader()
        testnames = testloader.getTestCaseNames(tc_class)
        suite = unittest.TestSuite()
        for name in testnames:
            suite.addTest(tc_class(name, cargs=args))
        return suite

    # Add all tests.
    alltests = unittest.TestSuite()
    for name, obj in inspect.getmembers(sys.modules[__name__]):
        if inspect.isclass(obj) and name.startswith("FooTest") and len(name) > len("FooTest"):
            alltests.addTest(make_suite(obj))

    # Run tests.
    result = unittest.TextTestRunner(verbosity=2).run(alltests)
    sys.exit(not result.wasSuccessful())

Then another wrapper for tests:

class FooTest(unittest.TestCase):
    def __init__(self, *args, cargs=None, **kwargs):
        super().__init__(*args, **kwargs)
        self.vdisplay = Xvfb(width=1280, height=720)
        self.vdisplay.start()
        self.args=cargs
        self.log=logging

    def setUp(self):
        self.site = webdriver.Firefox()

    def kill(self):
        self.vdisplay.stop()

Then each test in separate files would look like:

import sys, os, unittest
from FooTest import FooTest

class FooTest1(FooTest):

    def test_homepage(self):
        self.site.get(self.base_url + "/")
        log.debug("Home page loaded.")

Then you can easily run tests from shell like:

$ ./run_tests.py -h http://example.com/ test1.py test2.py

You can use wildcard to specify all files within certain directories, or use a new globbing option (**) to run all tests recursively (enable by shopt -s globstar).
