2.0.0 - 2016-01-10
------------------
Codename: A new beginning
This release cleans up all of the legacy that accrued in the course of
Hypothesis 1.0. These are mostly things that were emitting deprecation warnings
in 1.19.0, but there were a few additional changes.
In particular:
- non-strategy values will no longer be converted to strategies when used in
given or find.
- FailedHealthCheck is now an error and not a warning.
- Handling of non-ascii reprs in user types have been simplified by using raw
strings in more places in Python 2.
- given no longer allows mixing positional and keyword arguments.
- given no longer works with functions with defaults.
- given no longer turns provided arguments into defaults - they will not appear
in the argspec at all.
- the basic() strategy no longer exists.
- the n_ary_tree strategy no longer exists.
- the average_list_length setting no longer exists. Note: If you're using using
recursive() this will cause you a significant slow down. You should pass
explicit average_size parameters to collections in recursive calls.
- @rule can no longer be applied to the same method twice.
- Python 2.6 and 3.3 are no longer officially supported, although in practice
they still work fine.
This also includes two non-deprecation changes:
- given's keyword arguments no longer have to be the rightmost arguments and
can appear anywhere in the method signature.
- The max_shrinks setting would sometimes not have been respected.
1.19.0 - 2016-01-09
-------------------
Codename: IT COMES
This release heralds the beginning of a new and terrible age of Hypothesis 2.0.
It's primary purpose is some final deprecations prior to said release. The goal
is that if your code emits no warnings under this release then it will probably
run unchanged under Hypothesis 2.0 (there are some caveats to this: 2.0 will
drop support for some Python versions, and if you're using internal APIs then
as usual that may break without warning).
It does have two new features:
- New @seed() decorator which allows you to manually seed a test. This may be
harmlessly combined with and overrides the derandomize setting.
- settings objects may now be used as a decorator to fix those settings to a
particular @given test.
API changes (old usage still works but is deprecated):
- Settings has been renamed to settings (lower casing) in order to make the
decorator usage more natural.
- Functions for the storage directory that were in hypothesis.settings are now
in a new hypothesis.configuration module.
Additional deprecations:
- the average_list_length setting has been deprecated in favour of being
explicit.
- the basic() strategy has been deprecated as it is impossible to support it
under a Conjecture based model, which will hopefully be implemented at some
point in the 2.x series.
- the n_ary_tree strategy (which was never actually part of the public API) has
been deprecated.
- Passing settings or random as keyword arguments to given is deprecated (use
the new functionality instead)
Bug fixes:
- No longer emit PendingDeprecationWarning for __iter__ and StopIteration in
streaming() values.
- When running in health check mode with non strict, don't print quite so many
errors for an exception in reify.
- When an assumption made in a test or a filter is flaky, tests will now raise
Flaky instead of UnsatisfiedAssumption.
- The paste command will now open one tab/window per url if multiple
URLs (separated by newline) are present in the clipboard
- Adds the tests for the new multitab functionality
- Changes test/integration/conftest.py to be able to insert newlines in
the clipboard for the test
Using pytest.fail with pytrace=False hides the quteprocess output, which makes
it a lot harder to debug stuff.
This is because TestReport.longrepr is suddenly a string and we can't add infos
to it - see https://github.com/pytest-dev/pytest/issues/1316
While pytest-sugar was nice to look at, it produced a lot of issues:
- Unusable on CI
- Unusable on OS X and Windows
- Garbage when terminal was resized during tests
- Missing space after test name since some while
This replaces it by pytest-instafail, which replaces the most important feature
of sugar, and on top of that, also works on CI.
- qtbot.waitSignal with raising=True is the default this way, so we remove the
raising=True.
- qtbot.waitSignal with raising=False stay untouched
- Some qtbot.waitSignal without raising had one added (because we don't want it
to raise)
- Some qtbot.waitSignal without raising actually should've raised, which they
do now.
- New qt_wait_signal_raising ini option can be used to override the default
value of the raising parameter of the qtbot.waitSignal and qtbot.waitSignals
functions when omitted:
Calls which explicitly pass the raising parameter are not affected.
- qtbot now has a new assertNotEmitted context manager which can be used to
ensure the given signal is not emitted.
For some reason I can't explain, since 2b0870084b
we got test failures on OS X, as the clipboard had the old value before waiting
for the change, the new (correct) value after waiting for it, but never
actually emitted 'changed'.
We could just re-check the contents after the timeout, but that'd mean we wait
1s for every test where this weird thing happens.
Instead, we poll the clipboard for every 100ms as long as the timeout (1s)
hasn't passed, and return as soon as it has the correct contents.
The output was almost always useless without -v because the debug log wasn't
shown at all, only error/info.
Now we display a maximum of 50 lines (regardless of what level) without -v.
Checking the requests from the webserver proved problematic, as often there's
some kind of caching going on. Instead, we only check the log, as this is used
for things like :navigate anyways, so if the log says the page got loaded, we
can trust it.
There's still "... should be requested" to check the actual requests.
