Interval between tests in pytest

Question

Is there a common practice to add interval between tests in pytest? Currently integration tests fail but work fine if running the tests individually.

Answer 1

You can use autouse fixtures in pytest to automatically sleep in between test cases:

@pytest.fixture(autouse=True)
def slow_down_tests():
    yield
    time.sleep(1)

This fixture will automatically be used for all test cases and will yield execution to a test case so it can run normally, but when the test finishes, the execution will come back to this fixture and the sleep will be run.

If you want a teardown in a module for every function of the module:

import time
def teardown_function(function):   # the function parameter is optional
    time.sleep(3)

---

If you want a teardown in a class for every method of the class, you've two options.

1. In this you can't access the invoked method:

class TestClass:
    def teardown(self):
        time.sleep(1)

2. If you need to access it:

class TestClass:
    def teardown_method(self, method):
        print(method)
        time.sleep(1)

---

If you want a teardown that will be invoked once after a class:

@classmethod
def teardown_class(cls):
    print(cls)
    time.sleep(2)

All of this methods works in the same way for setups. You can see the documentation. Use fixtures for more complex implementations.

You can insert time.sleep(1) in the teardown method of each test, i.e:

class TestClass:
    def setup(self):
        pass

    def teardown(self):
        time.sleep(1) # sleep for 1 second
