更改由鼻子测试生成器创建的测试的名称 [英] Change names of tests created by nose test generators

问题描述

鼻子有一个错误-生成器创建的测试名称未缓存，因此错误看起来像是在上次测试中发生的错误，而不是在失败的实际测试中发生的错误.我在错误报告讨论中的解决方案之后解决了这个问题，但是它仅适用于标准输出上显示的名称，不适用于XML报告(--with-xunit)

Nose has a bug - test names created by generators are not cached, so the error looks like it happened in the last test, not the actual test where it failed. I got around it following the solution in the bug report discussion, but it only works for names shown on stdout, not in the XML report (--with-xunit)

from functools import partial, update_wrapper
def testGenerator():
    for i in range(10):
        func = partial(test)
        # make decorator with_setup() work again
        update_wrapper(func, test)
        func.description = "nice test name %s" % i
        yield func

def test():
    pass

鼻子的输出符合预期，类似

The output of nose is as expected, something like

nice test name 0 ... ok
nice test name 1 ... ok
nice test name 2 ... ok
...

但是XML中的测试名称只是'testGenerator'.

But the test names in XML are just 'testGenerator'.

...<testcase classname="example" name="testGenerator" time="0.000" />...

如何更改此设置，以便个性化测试名称同时显示在stdout和XML输出上?

我正在使用鼻子测试版本1.1.2和Python 2.6.6

I'm using nosetests version 1.1.2 and Python 2.6.6

推荐答案

您可以通过

You can change the way that Nose names tests by adding a plugin that implements describeTest

from nose.plugins import Plugin
class CustomName(Plugin):
    "Change the printed description/name of the test."
    def describeTest(self, test):
         return "%s:%s" % (test.test.__module__, test.test.description)

然后，您必须安装此插件，然后在鼻子"调用中启用它.

You will then have to install this plugin, and enable it in the Nose invocation.
