- Hide modifications Hypothesis needs to make to sys.path by undoing them after
we've imported the relevant modules. This is a workaround for issues
cryptography experienced on windows.
- Slightly improved performance of drawing from sampled_from on large lists of
alternatives.
- Significantly improved performance of drawing from one_of or strategies using
| (note this includes a lot of strategies internally - floats() and
integers() both fall into this category). There turned out to be a massive
performance regression introduced in 1.10.0 affecting these which probably
would have made tests using Hypothesis significantly slower than they should
have been.
- Better argument validation for datetimes() strategy - previously setting
max_year < datetime.MIN_YEAR or min_year > datetime.MAX_YEAR would not have
raised an InvalidArgument error and instead would have behaved confusingly.
- Compatibility with being run on pytest < 2.7 (achieved by disabling the
plugin).
Bug fixes:
- Settings(database=my_db) would not be correctly inherited when used as a
default setting, so that newly created settings would use the database_file
setting and create an SQLite example database.
- Settings.default.database = my_db would previously have raised an error and
now works.
- Timeout could sometimes be significantly exceeded if during simplification
there were a lot of examples tried that didn't trigger the bug.
- When loading a heavily simplified example using a basic() strategy from the
database this could cause Python to trigger a recursion error.
- Remove use of deprecated API in pytest plugin so as to not emit warning
Misc:
- hypothesis-pytest is now part of hypothesis core. This should have no
externally visible consequences, but you should update your dependencies to
remove hypothesis-pytest and depend on only Hypothesis.
- Better repr for hypothesis.extra.datetimes() strategies.
- Add .close() method to abstract base class for Backend (it was already
present in the main implemnetation).
Changelog:
Backward incompatibilities:
- Python versions supported are now:
- CPython 2.6, 2.7, 3.3, 3.4 and 3.5
- PyPy2 2.4, 2.6
- PyPy3 2.4
- The original command line switches (-x to run a program, etc) are no longer
supported.
- The COVERAGE_OPTIONS environment variable is no longer supported. It was a
hack for --timid before configuration files were available.
- The original module-level function interface to coverage.py is no longer
supported. You must now create a coverage.Coverage object, and use methods on
it.
- The Coverage.use_cache method is no longer supported.
- The private method Coverage._harvest_data is now called Coverage.get_data(),
and returns the CoverageData containing the collected data.
- Coverage.py is now licensed under the Apache 2.0 license. See NOTICE.txt for
details.
- Coverage.py kits no longer include tests and docs. If you were using them,
get in touch and let me know how.
Major new features:
- Plugins: third parties can write plugins to add file support for non-Python
files, such as web application templating engines, or languages that compile
down to Python. See Plugins for how to use plugins, and Plugin classes for
details of how to write them. A plugin for measuring Django template coverage
is available: django_coverage_plugin
- Gevent, eventlet, and greenlet are now supported. The [run] concurrency
setting, or the --concurrency command line switch, specifies the concurrency
library in use. Huge thanks to Peter Portante for initial implementation, and
to Joe Jevnik for the final insight that completed the work.
- The data storage has been re-written, using JSON instead of pickle. The
CoverageData class is a new supported API to the contents of the data file.
Data files from older versions of coverage.py can be converted to the new
format with python -m coverage.pickle2json.
- Wildly experimental: support for measuring processes started by the
multiprocessing module. To use, set --concurrency=multiprocessing, either on
the command line or in the .coveragerc file. Thanks, Eduardo Schettino.
Currently, this does not work on Windows.
New features:
- Options are now also read from a setup.cfg file, if any. Sections are
prefixed with “coverage:”, so the [run] options will be read from the
[coverage:run] section of setup.cfg.
- The HTML report now has filtering. Type text into the Filter box on the index
page, and only modules with that text in the name will be shown. Thanks,
Danny Allen.
- A new option: coverage report --skip-covered (or [report] skip_covered) will
reduce the number of files reported by skipping files with 100% coverage.
Thanks, Krystian Kichewko. This means that empty __init__.py files will be
skipped, since they are 100% covered.
- You can now specify the --fail-under option in the .coveragerc file as the
[report] fail_under option.
- The report -m command now shows missing branches when reporting on branch
coverage. Thanks, Steve Leonard.
- The coverage combine command now accepts any number of directories or files
as arguments, and will combine all the data from them. This means you don’t
have to copy the files to one directory before combining. Thanks, Christine
Lytwynec.
- A new configuration option for the XML report: [xml] package_depth controls
which directories are identified as packages in the report. Directories
deeper than this depth are not reported as packages. The default is that all
directories are reported as packages. Thanks, Lex Berezhny.
- A new configuration option, [run] note, lets you set a note that will be
stored in the runs section of the data file. You can use this to annotate the
data file with any information you like.
- The COVERAGE_DEBUG environment variable can be used to set the [run] debug
configuration option to control what internal operations are logged.
- A new version identifier is available, coverage.version_info, a plain tuple
of values similar to sys.version_info.
Improvements:
- Coverage.py now always adds the current directory to sys.path, so that
plugins can import files in the current directory.
- Coverage.py now accepts a directory name for coverage run and will run a
__main__.py found there, just like Python will. Thanks, Dmitry Trofimov.
- The --debug switch can now be used on any command.
- Reports now use file names with extensions. Previously, a report would
describe a/b/c.py as “a/b/c”. Now it is shown as “a/b/c.py”. This allows for
better support of non-Python files.
- Missing branches in the HTML report now have a bit more information in the
right-hand annotations. Hopefully this will make their meaning clearer.
- The XML report now contains a <source> element. Thanks Stan Hu.
- The XML report now includes a missing-branches attribute. Thanks, Steve Peak.
This is not a part of the Cobertura DTD, so the XML report no longer
references the DTD.
- The XML report now reports each directory as a package again. This was a bad
regression, I apologize.
- In parallel mode, coverage erase will now delete all of the data files.
- A new warning is possible, if a desired file isn’t measured because it was
imported before coverage.py was started.
- The coverage.process_startup() function now will start coverage measurement
only once, no matter how many times it is called. This fixes problems due to
unusual virtualenv configurations.
- Unrecognized configuration options will now print an error message and stop
coverage.py. This should help prevent configuration mistakes from passing
silently.
API changes:
- The class defined in the coverage module is now called Coverage instead of
coverage, though the old name still works, for backward compatibility.
- You can now programmatically adjust the configuration of coverage.py by
calling Coverage.set_option() after construction. Coverage.get_option() reads
the configuration values.
- If the config_file argument to the Coverage constructor is specified as
”.coveragerc”, it is treated as if it were True. This means setup.cfg is also
examined, and a missing file is not considered an error.
Bug fixes:
- The textual report and the HTML report used to report partial branches
differently for no good reason. Now the text report’s “missing branches”
column is a “partial branches” column so that both reports show the same
numbers. This closes issue 342.
- The fail-under value is now rounded the same as reported results, preventing
paradoxical results, fixing issue 284.
- Branch coverage couldn’t properly handle certain extremely long files. This
is now fixed, closing issue 359.
- Branch coverage didn’t understand yield statements properly. Mickie Betz
persisted in pursuing this despite Ned’s pessimism. Fixes issue 308 and issue
324.
- Files with incorrect encoding declaration comments are no longer ignored by
the reporting commands.
- Empty files are now reported as 100% covered in the XML report, not 0%
covered.
- The XML report will now create the output directory if need be. Thanks, Chris
Rose.
- HTML reports no longer raise UnicodeDecodeError if a Python file has
undecodable characters.
- The annotate command will now annotate all files, not just ones relative to
the current directory.
Changes:
- Don't mark shadowing variable as 'used'.
- Test that used variable in loop is considered used
- Don't report UnusedImport when binding global name
- Support Python 3.5 async/await statements for Pyflakes.
- Use os.linesep for Windows compatibility
- os.chmod() supports only read-only flag operations on Windows
Bug fixes:
- When running Hypothesis tests in parallel (e.g. using pytest-xdist) there was
a race condition caused by code generation.
- Example databases are now cached per thread so as to not use sqlite
connections from multiple threads. This should make Hypothesis now entirely
thread safe.
- floats() with only min_value or max_value set would have had a very bad
distribution.
- Running on 3.5, Hypothesis would have emitted deprecation warnings because of
use of inspect.getargspec
Changelog:
- Allow 'dev', 'rc', or other non-integer version strings in `importorskip`.
Thanks to Eric Hunsberger for the PR.
- fix issue856: consider --color parameter in all outputs (for example
--fixtures). Thanks Barney Gale for the report and Bruno Oliveira for the PR.
- fix issue855: passing str objects as `plugins` argument to pytest.main
is now interpreted as a module name to be imported and registered as a
plugin, instead of silently having no effect.
Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
- fix issue744: fix for ast.Call changes in Python 3.5+. Thanks
Guido van Rossum, Matthias Bussonnier, Stefan Zimmermann and
Thomas Kluyver.
- fix issue842: applying markers in classes no longer propagate this markers
to superclasses which also have markers.
Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
- preserve warning functions after call to pytest.deprecated_call. Thanks
Pieter Mulder for PR.
- fix issue854: autouse yield_fixtures defined as class members of
unittest.TestCase subclasses now work as expected.
Thannks xmo-odoo for the report and Bruno Oliveira for the PR.
- fix issue833: --fixtures now shows all fixtures of collected test files, instead of just the
fixtures declared on the first one.
Thanks Florian Bruhin for reporting and Bruno Oliveira for the PR.
- fix issue863: skipped tests now report the correct reason when a skip/xfail
condition is met when using multiple markers.
Thanks Raphael Pierzina for reporting and Bruno Oliveira for the PR.
- optimized tmpdir fixture initialization, which should make test sessions
faster (specially when using pytest-xdist). The only visible effect
is that now pytest uses a subdirectory in the $TEMP directory for all
directories created by this fixture (defaults to $TEMP/pytest-$USER).
Thanks Bruno Oliveira for the PR.
- Reduced verbosity when exceptions are captured in virtual methods.
- `pytestqt.plugin` has been split in several files and tests have been
moved out of the `pytestqt` package. This should not affect users, but it
is worth mentioning nonetheless.
- `QApplication.processEvents()` is now called before and after other fixtures
and teardown hooks, to better try to avoid non-processed events from leaking
from one test to the next.
- Show Qt/PyQt/PySide versions in pytest header.
- Disconnect SignalBlocker functions after its loop exits to ensure second
emissions that call the internal functions on the now-garbage-collected
SignalBlocker instance.
Changelog:
- text() with a non-string alphabet would have used the repr() of the the
alphabet instead of its contexts. This is obviously silly. It now works with
any sequence of things convertible to unicode strings.
- @given will now work on methods whose definitions contains no explicit
positional arguments, only varargs. This may have some knock on effects
because it means that @given no longer changes the argspec of functions other
than by adding defaults.
- Introduction of new @composite feature for more natural definition of
strategies you'd previously have used flatmap for.
Upstream changelog:
* lists(elements, unique_by=some_function, min_size=n) would have raised a
ValidationError if n > Settings.default.average_list_length because it would
have wanted to use an average list length shorter than the minimum size of
the list, which is impossible. Now it instead defaults to twice the minimum
size in these circumstances.
* basic() strategy would have only ever produced at most ten distinct values
per run of the test (which is bad if you e.g. have it inside a list). This
was obviously silly. It will now produce a much better distribution of data,
both duplicated and non duplicated.
* star imports from hypothesis should now work correctly.
* example quality for examples using flatmap will be better, as the way it had
previously been implemented was causing problems where Hypothesis was
erroneously labelling some examples as being duplicates.
- The environment to run unittests is now called py34 as that's the common
thing used, and will also allow us to run the tests with Python 3.5.
- The default tests now also run coverage.py and do a coverage check (on
Linux).
- The smoke tests are now part of the default environment.
This is just a bugfix and performance release, but it changes some semi-public
APIs, hence the minor version bump.
- Significant performance improvements for strategies which are one_of() many
branches. In particular this included recursive() strategies. This should
take the case where you use one recursive() strategy as the base strategy of
another from unusably slow (tens of seconds per generated example) to
reasonably fast.
- Better handling of just() and sampled_from() for values which have an
incorrect __repr__ implementation that returns non-ASCII unicode on Python 2.
- Better performance for flatmap from changing the internal morpher API to be
significantly less general purpose.
- Introduce a new semi-public BuildContext/cleanup API. This allows strategies
to register cleanup activities that should run once the example is complete.
Note that this will interact somewhat weirdly with find.
- Better simplification behaviour for streaming strategies.
- Don't error on lambdas which use destructuring arguments in Python 2.
- Add some better reprs for a few strategies that were missing good ones.
- The Random instances provided by randoms() are now copyable.
- Slightly more debugging information about simplify when using a debug
verbosity level.
- Support using given for functions with varargs, but not passing arguments to
it as positional.
Changelog:
Filter out YES nodes when creating a temporary class for the with_metaclass
hack.
Having an YES node in a class bases will lead to a crash with a TypeError
when trying to obtain the ancestors of the given class, because .ancestors()
will try to iterate each inferred node from the bases, thus will try to
iterate over an YES node.
Upstream changelog:
Exceptions are now captured also during test tear down, as delayed events will
get processed then and might raise exceptions in virtual methods; this is
specially problematic in PyQt5.5, which changed the behavior to call abort by
default, which will crash the interpreter.
