Suppress a health check everywhere
==================================
Hypothesis sometimes raises a |HealthCheck| to indicate that your test may be less effective than you expect, slower than you expect, unlikely to generate effective examples, or otherwise has silently degraded performance.
While |HealthCheck| can be useful to proactively identify issues, you may not care about certain classes of them. If you want to disable a |HealthCheck| everywhere, you can register and load a settings profile with |settings.register_profile| and |settings.load_profile|. Place the following code in any file which is loaded before running your test (or in ``conftest.py``, if using pytest):
.. code-block:: python
from hypothesis import HealthCheck, settings
settings.register_profile(
"my_profile", suppress_health_check=[HealthCheck.filter_too_much]
)
settings.load_profile("my_profile")
This profile in particular suppresses the |HealthCheck.filter_too_much| health check for all tests. The exception is if a test has a |@settings| which explicitly sets a different value for ``suppress_health_check``, in which case the profile value will be overridden by the local settings value.
I want to suppress all health checks!
-------------------------------------
.. warning::
We strongly recommend that you suppress health checks as you encounter them, rather than using a blanket suppression. Several health checks check for subtle interactions that may save you hours of debugging, such as |HealthCheck.function_scoped_fixture| and |HealthCheck.differing_executors|.
If you really want to suppress *all* health checks, for instance to speed up interactive prototyping, you can:
.. code-block:: python
from hypothesis import HealthCheck, settings
settings.register_profile("my_profile", suppress_health_check=list(HealthCheck))
settings.load_profile("my_profile")
