Small Errors Thread

[Adrian Scheffler]

Hi,
http://chimera.labs.oreilly.com/books/1234000000754/ch06.html#_removing_now_redundant_code_and_tests The programlisting is not syntax highlighted as usual.
If i spot more small errors like this, i will post it here so that the group gets not polluted with this unimportant stuff.
Very pleasant reading. Thanks!

At http://chimera.labs.oreilly.com/books/1234000000754/ch06.html#_implementing_the_new_design_using_tdd, in the code listing for tests.py, the last line has 'satisified' instead of 'satisfied'.  I don't think that is a British spelling?

[Steve Young]

And a bit past the above block you have a section starting with 

"I found the FTs hung when I tried to run them today...." and suggest upgrading Selenium.  At the beginning of the book you said to use 2.39 - so this is a bit confusing.  

I am sticking with 2.39 myself. :-)

At: lists/tests.py (ch06l021-2) in http://chimera.labs.oreilly.com/books/1234000000754/ch06.html#_a_test_class_for_new_list_creation

There seem to be some typos in the code - unless Dan and I are implementing something wrong.  The comments show how I got things working.

[Steve Young]

Well, a bit further down the page I had to revert the trailing slashes - another comment is on the page.  Not sure where the mixup was, but probably something I did?

The Repo's https://github.com/hjwp/book-example last push was at --ch08l003--

[Harry Percival]

I suspect this was an inconsistency between urls.py and tests.py.   Neither should use trailing slashes for the url /lists/new, but if they differ, you see confusing 301 redirects...

http://chimera.labs.oreilly.com/books/1234000000754/ch12.html#_another_ft_for_duplicate_items OK, so we know the first of the two tests passes now, is there a way to run just the failing one, I hear you ask! Why yes indeed:

A general thing: I wonder why you say in one place, that a test is best analysed from behind, while not explaining all tests that way (with these orange numbers).

http://chimera.labs.oreilly.com/books/1234000000754/ch16.html#_beware_of_mocks_in_boolean_comparisons This section is slightly counterintuitive for  me, because i think this problem should be addressed right away, when the test is introduced and doesn't fail. At the beginning you mentioned the importance  of seeing the tests fail before fixing them and this seems to be a good example.
