Is there any way to use the same fixture multiple times in a function with pytest?

Question

Like this

@pytest.fixture
def myfixture():
   # creates a complex object

def test_compare(myfixture,myfixture):
   #compares

Is there a way to know which fixture am I working on? The generated objects are different

Thanks

Answer 1

You are looking for factory pattern https://docs.pytest.org/en/latest/fixture.html#factories-as-fixtures

Here is SO question about advantages of fixture factories Why would a pytest factory as fixture be used over a factory function?

Answering your question

@pytest.fixture
def myfixture():
   def _make_fixture():
       # creates a complex object
   return _make_fixture

def test_compare(myfixture):
    data1 = myfixture()
    data2 = myfixture()
    #compares

Answer 2

Why you want to compare objects returned by fixture? Fixtures are not meant to be so.

As per the documentation,

The purpose of test fixtures is to provide a fixed baseline upon which tests can reliably and repeatedly execute.

If you want to compare returned objects, just make it as a function, not as a fixture.Like.

def myfixture():
   # creates a complex object

def test_compare():
   a=myfixture()
   b=myfixture()
   #compare a and b
