Zope Application Testing Support
Project description
zope.app.testing
This package provides testing support for Zope 3 applications. Besides providing numerous setup convenience functions, it implements a testing setup that allows the user to make calls to the publisher allowing to write functional tests.
FDocTest (How-To)
Steps to get started:
Use a clean/missing Data.fs
Create a manager with the name “mgr”, password “mgrpw”, and grant the zope.Manager role.
Install tcpwatch.
Create a temporary directory to record tcpwatch output.
Run tcpwatch using: tcpwatch.py -L 8081:8080 -s -r tmpdir (the ports are the listening port and forwarded-to port; the second need to match the Zope configuration)
In a browser, connect to the listening port and do whatever needs to be recorded.
Shut down tcpwatch.
Run the script src/zope/app/testing/dochttp.py: python2.4 src/zope/app/testing/dochttp.py tmpdir > somefile.txt
Edit the generated text file to add explanations and elide uninteresting portions of the output.
In a functional test module (usually ftests.py), import FunctionalDocFileSuite from zope.app.testing.functional and instantiate it, passing the name of the text file containing the test.
DocTest Functional Tests
This file documents and tests doctest-based functional tests and basic Zope web-application functionality.
Request/Response Functional Tests
You can create Functional tests as doctests. Typically, this is done by using a script such as src/zope/app/testing/dochttp.py to convert tcpwatch recorded output to a doctest, which is then edited to provide explanation and to remove uninteresting details. That is how this file was created.
Here we’ll test some of the most basic types of access.
First, we’ll test accessing a protected page without credentials:
>>> print(http(r""" ... GET /@@contents.html HTTP/1.1 ... """)) HTTP/1.1 401 Unauthorized Cache-Control: no-store, no-cache, must-revalidate Content-Length: ... Content-Type: text/html;charset=utf-8 Expires: Mon, 26 Jul 1997 05:00:00 GMT Pragma: no-cache WWW-Authenticate: basic realm="Zope" <BLANKLINE> <!DOCTYPE html PUBLIC ...
Here we see that we got:
A 401 response,
A WWW-Authenticate header, and
An html body with an error message
Some technical headers to keep squid happy
Note that we used ellipsis to indicate ininteresting details.
Next, we’ll access the same page with credentials:
>>> print(http(r""" ... GET /@@contents.html HTTP/1.1 ... Authorization: Basic mgr:mgrpw ... """)) HTTP/1.1 200 OK Content-Length: ... Content-Type: text/html;charset=utf-8 <BLANKLINE> <!DOCTYPE html PUBLIC ...
Important note: you must use the user named “mgr” with a password “mgrpw”.
And we get a normal output.
Next we’ll try accessing site management. Since we used “/manage”, we got redirected:
>>> print(http(r""" ... GET /++etc++site/@@manage HTTP/1.1 ... Authorization: Basic mgr:mgrpw ... Referer: http://localhost:8081/ ... """)) HTTP/1.1 303 See Other Content-Length: 0 Content-Type: text/plain;charset=utf-8 Location: @@contents.html <BLANKLINE>
Note that, in this case, we got a 303 response. A 303 response is the prefered response for this sort of redirect with HTTP 1.1. If we used HTTP 1.0, we’d get a 302 response:
>>> print(http(r""" ... GET /++etc++site/@@manage HTTP/1.0 ... Authorization: Basic mgr:mgrpw ... Referer: http://localhost:8081/ ... """)) HTTP/1.0 302 Moved Temporarily Content-Length: 0 Content-Type: text/plain;charset=utf-8 Location: @@contents.html <BLANKLINE>
Lets visit the page we were redirected to:
>>> print(http(r""" ... GET /++etc++site/@@contents.html HTTP/1.1 ... Authorization: Basic mgr:mgrpw ... Referer: http://localhost:8081/ ... """)) HTTP/1.1 200 OK Content-Length: ... Content-Type: text/html;charset=utf-8 <BLANKLINE> <!DOCTYPE html PUBLIC ...
Finally, lets access the default page for the site:
>>> print(http(r""" ... GET / HTTP/1.1 ... Authorization: Basic mgr:mgrpw ... """)) HTTP/1.1 200 OK Content-Length: ... Content-Type: text/html;charset=utf-8 <BLANKLINE> <!DOCTYPE html PUBLIC ...
Access to the object system
You can use the getRootFolder() function:
>>> root = getRootFolder() >>> root <zope.site.folder.Folder object at ...>
You can intermix HTTP requests with regular Python calls. Note, however, that making an http() call implied a transaction commit. If you want to throw away changes made in Python code, abort the transaction before the HTTP request.
>>> print(http(r""" ... POST /@@contents.html HTTP/1.1 ... Authorization: Basic mgr:mgrpw ... Content-Length: 73 ... Content-Type: application/x-www-form-urlencoded ... ... type_name=BrowserAdd__zope.site.folder.Folder&new_value=f1""", ... handle_errors=False)) HTTP/1.1 303 See Other Content-Length: ... Content-Type: text/html;charset=utf-8 Location: http://localhost/@@contents.html <BLANKLINE> <!DOCTYPE html ...
Now we can see that the new folder was added:
>>> [str(x) for x in root.keys()] ['f1']
CHANGES
4.0.0 (2018-10-24)
Remove zope.app.testing.testbrowser. It was not compatible with zope.testbrowser version 5.
Add basic support for Python 3.5, 3.6 and 3.7.
3.10.0 (2012-01-13)
Removed test dependency on zope.app.authentication.
zope.testbrowser 4 depends on this change (seriously) if it find zope.app.testing.
3.9.0 (2011-03-14)
Move zope.app.testing testbrowser functionality into zope.app.testing. This requires zope.testbrowser version 4.0.0 or above.
3.8.1 (2011-01-07)
Include REMOTE_ADDR (‘127.0.0.1’) in the request environment.
3.8.0 (2010-09-14)
Remove invalid HTTP_REFERER default. (We both don’t want a default to allow others testing without a referer and ‘localhost’ is not a reasonable default anyway.) This improves the situation for #98437
Made the xmlrpc code compatible with Python 2.7.
Removed test dependency on zope.app.zptpage.
Switched test dependency from zope.app.securitypolicy to zope.securitypolicy.
3.7.7 (2010-09-14)
Rereleasing 3.7.5 as 3.7.7 to fix brown bag release.
3.7.6 (2010-09-14)
Brown bag release: It broke the tests of zope.testbrowser.
3.7.5 (2010-04-10)
Switch doctests to use the stdlib doctest module, rather than the deprecated zope.testing.doctest variant.
3.7.4 (2010-01-08)
Import hooks functionality from zope.component after it was moved there from zope.site.
Import ISite from zope.component after it was moved there from zope.location. This lifts the dependency on zope.location.
Fix tests using a newer zope.publisher that requires zope.login.
3.7.3 (2009-08-20)
Fixed tests for python 2.4 as well as python 2.5 and 2.6; the change in version 3.7.1 introduced test regressions in python 2.4.
3.7.2 (2009-07-24)
Adjusted tests after the referenced memory leak problem has been fixed in zope.component.
3.7.1 (2009-07-21)
Fixed failing tests. The code revealed that the tests expected the wrong value.
3.7.0 (2009-06-19)
Depend on new zope.processlifetime interfaces instead of using BBB imports from zope.app.appsetup.
Removed unused dependency on zope.app.component.
3.6.2 (2009-04-26)
Removed deprecated back35 module and loose the dependency on zope.deferredimport.
Adapt to zope.app.authentication refactoring. We depend on zope.password now instead.
Adapt to latest zope.app.security refactoring. We don’t need this package anymore.
3.6.1 (2009-03-12)
Use ISkinnable.providedBy(request) instead of IBrowserRequest as condition for calling setDefaultSkin in HTTPCaller. This at the same time removes dependency to the browser part of zope.publisher.
Adapt to the move of IDefaultViewName from zope.component.interfaces to zope.publisher.interfaces.
Remove the DEPENDENCIES.cfg file for zpkg.
3.6.0 (2009-02-01)
Fix AttributeError in zope.app.testing.setup.setUpTestAsModule (when called without name argument).
Use zope.container instead of zope.app.container.
Use zope.site instead of zope.app.folder and zope.app.component for some parts.
3.5.6 (2008-10-13)
Change argument variable name in provideAdapter to not conflict with buitin keyword in Python 2.6.
3.5.5 (2008-10-10)
Re-configured functional test setup to create test-specific instances of HTTPCaller to ensure that cookies are not shared by doctests in a test suite.
3.5.4 (2008-08-25)
Clean up some transaction management in the functional test setup.
3.5.3 (2008-08-22)
Fix isolation enforcement for product configuration around individual tests.
3.5.2 (2008-08-21)
Added missing dependency information in setup.py.
Added missing import.
Repair memory leak fix released in 3.4.3 to be more sane in the presence of generations.

Fix memory leak in all functional tests. see: https://bugs.launchpad.net/zope3/+bug/251273
3.4.2 (2008-02-02)
Fix of 599 error on conflict error in request see: http://mail.zope.org/pipermail/zope-dev/2008-January/030844.html
