在C＃中使用的ScriptEngine（.NET 3.5）执行麻烦硒蟒蛇单元测试 [英] trouble executing Selenium python unittests in C# with ScriptEngine (.NET 3.5)

问题描述

第一次海报。

我转向我的堆栈溢出的第一个问题，因为我发现很少的资源，试图找到答案。我期待从C＃应​​用程序执行硒蟒蛇测试。我不想每次都编译C＃Selenium测试;我想利用IronPython的脚本进行动态测试硒。 （注：我很少有Python或的ScriptEngine等经验。）

I'm turning to my first question on stack overflow because I've found little resources in trying to find an answer. I'm looking to execute Selenium python tests from a C# application. I don't want to have to compile the C# Selenium tests each time; I want to take advantage of IronPython scripting for dynamic selenium testing. (note: I have little Python or ScriptEngine, et al experience.)

硒输出单元测试在Python中的格式如下：

Selenium outputs unit tests in python in the following form:

from selenium import selenium
import unittest

class TestBlah(unittest.TestCase):
    def setUp(self):
        self.selenium = selenium(...)
        self.selenium.start()

    def test_blah(self):
        sel = self.selenium
        sel.open("http://www.google.com/webhp")
        sel.type("q", "hello world")
        sel.click("btnG")
        sel.wait_for_page_to_load(5000)
        self.assertEqual("hello world - Google Search", sel.get_title())
        print "done"

    def tearDown(self):
        self.selenium.stop()

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

我可以使用ipy.exe得到这个跑，没问题，在命令行：

I can get this to run, no problem, from the command line using ipy.exe:

ipy test_google.py

和我能看到硒服务器启动一个Firefox浏览器实例并运行测试。

And I can see Selenium Server fire up a firefox browser instance and run the test.

我不能达到使用的ScriptEngine等在C＃API，.NET 3.5相同的结果，我想它周围不能够执行我猜下面的代码在main（）函数中心是：

I cannot achieve the same result using the ScriptEngine, et al API in C#, .NET 3.5, and I think it's centered around not being able to execute the main() function I'm guessing the following code is:

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

我试过engine.ExecuteFile（ ），engine.CreateScriptSourceFromString（）/ source.Execute（），和engine.CreateScriptSourceFromFile（）/ source.Execute（）。我试图scope.SetVariable（ __ __名， __ __主要）。我做的时候我注释掉engine.Runtime如果 __名的PY文件的一部分，并呼吁engine.CreateScriptSourceFromString（unittest.main（模块=无）后__获得一些成功.ExecuteFile（）被调用的PY文件。我已经试过存储蟒蛇的结果，并通过scope.GetVariable访问它们（）。我也试着写一个Python的功能，我可以从C＃调用执行单元测试。

I've tried engine.ExecuteFile(), engine.CreateScriptSourceFromString()/source.Execute(), and engine.CreateScriptSourceFromFile()/source.Execute(). I tried scope.SetVariable("__name__", "__main__"). I do get some success when I comment out the if __name__ part of the py file and call engine.CreateScriptSourceFromString("unittest.main(module=None") after engine.Runtime.ExecuteFile() is called on the py file. I've tried storing the results in python and accessing them via scope.GetVariable(). I've also tried writing a python function I could call from C# to execute the unit tests.

（发动机的ScriptEngine的实例，源ScriptSource的一个实例，等。）

(engine is an instance of ScriptEngine, source an instance of ScriptSource, etc.)

我的无知Python中，的ScriptEngine，或unittest模块可以很容易地背着我的烦恼。有没有人有任何运气执行使用的ScriptEngine等在C＃中API的Python单元测试？有没有人成功地执行从的ScriptEngine主的代码？

My ignorance of Python, ScriptEngine, or the unittest module could easily be behind my troubles. Has anyone had any luck executing python unittests using the ScriptEngine, etc API in C#? Has anyone successfully executed "main" code from ScriptEngine?

此外，我读过，单元测试有一个测试运行，将在通过的TestResult对象访问错误的帮助，我相信语法如下，我这里没有得到还没有，但知道我需要收获的结果。

Additionally, I've read that unittest has a test runner that will help in accessing the errors via a TestResult object. I believe the syntax is the following. I haven't gotten here yet, but know I'll need to harvest the results.

unittest.TextTestRunner(verbosity=2).run(unittest.main())

提前

感谢。我想这会是最好有更多的细节以内。 = P

Thanks in advance. I figured it'd be better to have more details than less. =P

推荐答案

综观的源代码到IronPython的控制台（ipy.exe），它看起来像它最终归结为调用 ScriptSource.ExecuteProgram（） 。你可以得到一个 ScriptSource 从任意的各种 ScriptEngine.CreateScriptSourceFrom * 方法。

Looking at the source code to the IronPython Console (ipy.exe), it looks like it eventually boils down to calling ScriptSource.ExecuteProgram(). You can get a ScriptSource from any of the various ScriptEngine.CreateScriptSourceFrom* methods.

例如：

import clr
clr.AddReference("IronPython")

from IronPython.Hosting import Python
engine = Python.CreateEngine()
src = engine.CreateScriptSourceFromString("""
if __name__ == "__main__":
    print "this is __main__"
""")

src.ExecuteProgram()

运行这个将打印这是主要
