I don't think that what you showed is the actual code that get executed.

I and others belive that, for a couple of reasons:

<ul>
<li>If <code>self.assertTrue(r.ok)</code> fails then the line before will too. Therefore <code>self.assertTrue(r.ok)</code> won't execute. (as <a href="https://stackoverflow.com/questions/9541397/name-self-is-not-defined-when-doing-an-unittest#comment12090465_9541397">David Heffernan</a> said)</li>
<li>And because your code looks fine.</li>
</ul>

I'd say that you probably made a typo of this kind:

<pre><code>def test_scm_permission(self):
 ^
 |
 and wrote something here that's not self
</code></pre>

In some file that get executed instead of the one you're showing.

Take a look at this example:

<pre><code># test.py
class MyClass:

 def func(sel): # typo error here
 self.name = 10


obj = MyClass()
obj.func()
</code></pre>

And when I tried to run:

<pre><code>$ python3 test.py 
Traceback (most recent call last):
 File "test.py", line 8, in &lt;module&gt;
 obj.func()
 File "test.py", line 4, in func
 self.name = 10
NameError: global name 'self' is not defined
</code></pre>

Having a traceback similar to yours.

Note: Also if I'm not counting wrong <code>self.assertTrue(r.ok)</code> is on line 18, instead of line 19 (which is the number showed in your traceback).

blocks|key|874862|text|这是大卫·赫弗南的评论的重新措辞。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|874863|您发布的代码不可能是该跟踪的原因。|874864|考虑代码中的这两行：|874865|r+=+requests.get("http://192.168.1.138:6666/scm/",+auth=(self.username,+self.password))

This is a rewording of David Heffernan's comment.

The code you posted cannot be the cause of that traceback.

Consider these two lines from your code:

<pre><code>r = requests.get("http://192.168.1.138:6666/scm/", auth=(self.username, self.password))
self.assertTrue(r.ok)
</code></pre>

The traceback says the error (<code>NameError: name 'self' is not defined</code>)
 occurs on the second line (<code>self.assertTrue(r.ok)</code>). However, this cannot have been the case because the first line refers to <code>self</code>. If <code>self</code> were not defined, we would not get past the first line.

Therefore, the code you posted is not the code you ran.

blocks|key|428945|text|我不知道问题是从哪里来的--是复制错误，还是执行了错误的test.py更新:还是一些混合的制表符和空格问题，我永远找不出它们何时被标记，什么时候没有--但根本原因几乎肯定是缩进错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|428946|请注意，错误消息是|428947|NameError:+name+'self'+is+not+defined|code-block|syntax|javascript|428948|而不是|428949|NameError:+global+name+'self'+is+not+defined|428950|@Rik+Poggi得到的。如果您在/向上移动self.assertTrue一级，则会发生这样的情况：|offset|length|style|CODE|428951|~/coding$+cat+test_good_indentation.py

I'm not sure where the problem is coming from -- whether it's a copying error or the wrong test.py is being executed [update: or some mixed tabs-and-spaces issue, I can never figure out when those get flagged and when they don't] -- but the root cause is almost certainly an indentation error.

Note that the error message is

<pre><code>NameError: name 'self' is not defined
</code></pre>

and not

<pre><code>NameError: global name 'self' is not defined
</code></pre>

which @Rik Poggi got. This is exactly what happens if you move the <code>self.assertTrue</code> one level in/up:

<pre><code>~/coding$ cat test_good_indentation.py
import unittest

class TestWriteFile(unittest.TestCase):
 def test(self):

versus 

<pre><code>~/coding$ cat test_bad_indentation.py

class TestWriteFile(unittest.TestCase):

 """

 self.assertTrue(1)

if __name__ == '__main__':

NameError: name 'self' is not defined
</code></pre>

blocks|key|874949|text|这是个老生常谈的问题，但我想我应该加上我的两分钱，因为这里没有提到这个问题。我同意其他人的看法，即原代码中存在某种类型的拼写错误。仔细看一下这段代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|874950|import+unittest

++++++++self.username+=+'dummy'

++++++++self.assertTrue(r.ok)|code-block|syntax|javascript|874951|乍一看，代码看起来还不错(林特工具不会抱怨)；但是，我编写了setup，而不是setUp+(注意大写的U)。这会导致self.username不会在test_scm_permission上下文中定义，因为test_scm_permission不会自动调用我的错误函数名。这还需要检查您是否遇到了这种类型的错误，但是可以肯定您已经正确地定义了类成员。|offset|length|style|BOLD|874952|entityMap^0|0|0|U|5|13|5|1F|1|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]|$I|V|J|W|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|N|$]]

This is an old question, but thought I'd add my two cents as it was not mentioned here. I agree with others that there is some type of spelling error in the original code. Look at this code carefully:

<pre><code>import unittest
import requests

class TestWriteFile(unittest.TestCase):
 def setup(self):
 self.username = 'dummy'

 def test_scm_permission(self):
 r = requests.get("http://192.168.1.138:6666/scm/", auth=(self.username, self.password))
 self.assertTrue(r.ok)
</code></pre>

The code appears okay at first glance (and lint tools will not complain); however, I wrote setup, instead of setUp (note the capital U). This causes self.username not to be defined in the test_scm_permission context, because python did not automatically call my mispelled function name. This is something else to check if you're running into this type of error, but are certain you've defined the class members correctly.

blocks|key|428979|text|我也有同样的问题，但对赛尔夫却不是。它是一个常规变量，在错误发生之前定义了行。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|428980|显然是因为..。混合制表符和空格。|428981|我用4个空格替换了所有制表符，问题就消失了。|428982|由于一些不明确的原因，我有这个错误，而不是传统的缩进错误。|428983|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

I had the same problem, but not with self. It was a regular variable, defined the line before the error occured.

It was apparently due to ... mixin tabs and spaces.

I replaced all tabs by 4 spaces, and the problem disappeared.

For some unspecified reason, instead of the traditional indentation error, I had this one.

Edit

So I did try again, with a new file called <code>test2.py</code> and it works. I packaged <code>repoman</code> , and <code>test.py</code> is in the <code>src</code> folder. I modified <code>test.py</code> after I created and installed my <code>repoman egg</code>. I think that's the problem. But thanks for the help. Do you guys think that's the exact reason?

<hr>

<pre><code>import unittest
import requests
from repoman.core import ultraman, supported
from repoman.ext import writefile,locate_repo

class TestWriteFile(unittest.TestCase):

 def setUp(self):
 self.username = 'dummy'
 self.password = 'dummy'
 self.remote = 'http://192.168.1.138:6666/scm/hg/NCL'

 def test_scm_permission(self):
 """
 Test SCM login.
 """
 r = requests.get("http://192.168.1.138:6666/scm/", auth=(self.username, self.password))
 self.assertTrue(r.ok)

if __name__ == '__main__':
 unittest.main()
</code></pre>

Running <code>python test.py</code> I get this error:

<pre><code>Traceback (most recent call last):
 File "test.py", line 7, in &lt;module&gt;
 class TestWriteFile(unittest.TestCase):
 File "test.py", line 19, in TestWriteFile
 self.assertTrue(r.ok)
NameError: name 'self' is not defined
</code></pre>

I don't think I need to overwrite <code>__init__</code> function, do I? What's causing this? Why is <code>self</code> not defined? I already declared my superclass <code>unittest.TestCase</code>

Thanks.

I basically learned it from the official sample: <a href="http://docs.python.org/library/unittest.html" rel="noreferrer">Unittest - Basic Example</a>

name 'self' is not defined when doing an unittest?

编辑所以我又试了一次，使用了一个名为test2.py的新文件，它可以工作。我打包了repoman，test.py在src文件夹中。在创建和安装了我的test.py之后，我修改了repoman egg。我想这就是问题所在。但是谢谢你的帮助。你们认为这就是真正的原因吗？import unittestimport reque...
