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 define and load a settings profile. Place the following code in any file which is loaded before running your test (or in conftest.py, if using pytest):

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:

from hypothesis import HealthCheck, settings

settings.register_profile("my_profile", suppress_health_check=list(HealthCheck))
settings.load_profile("my_profile")
