Test that depends on other tests in different file always skipped

[tkedwards]

Hi,

I have a test that depends on 2 other tests:

# Test the GrowthQuality sub-class

import pytest
from SharepadDaten.calcvalues.calcs.GrowthQuality import *

@pytest.mark.parametrize("sharecode,expected", [
    ('RTN.L', Decimal(0.703).quantize(Decimal('.001'))),
    ('FL', Decimal(0.811).quantize(Decimal('.001'))),
    ('ALV.DE', Decimal(0.784).quantize(Decimal('.001'))),
])

@pytest.mark.dependency(
    depends=["tests_calculatedvalues/test_leaseLiabilities.py::test_leaseLiabilities", "tests_calculatedvalues/test_leaseAdjCapEmp.py::test_leaseAdjCapEmp"],
    scope='session'
)
def test_calcGrowthQuality(sharecode, expected, dbsession, tables):
    dbSession = dbsession
    SQLAlcBase = tables
    sharesDetailsClass = SQLAlcBase.classes['sharesDetails']   
    growthQuality = GrowthQuality(sharecode, dbSession, SQLAlcBase)
    assert growthQuality.value == expected

It depends on these 2 other tests, which are defined in separate .py files in the same directory:

@pytest.mark.dependency(name="test_leaseAdjCapEmp")
def test_leaseAdjCapEmp(sharecode, expected, dbsession, tables):
    dbSession = dbsession
    SQLAlcBase = tables
    sharesDetailsClass = SQLAlcBase.classes['sharesDetails']   
    leaseAdjCapEmpObj = leaseAdjCapEmp(sharecode, dbSession, SQLAlcBase)
    # IntermediateCalculatedValue tests should actually write to the DB, since other tests rely on these values being there
    leaseAdjCapEmpObj.outputValue() 
    assert leaseAdjCapEmpObj.values.equals(expected)

@pytest.mark.dependency(name="test_leaseLiabilities")
def test_leaseLiabilities(sharecode, expected, dbsession, tables):
    dbSession = dbsession
    SQLAlcBase = tables
    sharesDetailsClass = SQLAlcBase.classes['sharesDetails']   
    leaseLiab = leaseLiabilities(sharecode, dbSession, SQLAlcBase)
    # IntermediateCalculatedValue tests should actually write to the DB, since other tests rely on these values being there
    leaseLiab.outputValue() 
    assert leaseLiab.values.equals(expected)

When I run my tests I get:

SKIPPED [1] /usr/local/lib/python3.8/dist-packages/pytest_dependency.py:104: test_calcGrowthQuality[RTN.L-expected0] depends on tests_calculatedvalues/test_leaseAdjCapEmp.py::test_leaseAdjCapEmp
SKIPPED [1] /usr/local/lib/python3.8/dist-packages/pytest_dependency.py:104: test_calcGrowthQuality[FL-expected1] depends on tests_calculatedvalues/test_leaseAdjCapEmp.py::test_leaseAdjCapEmp
SKIPPED [1] /usr/local/lib/python3.8/dist-packages/pytest_dependency.py:104: test_calcGrowthQuality[ALV.DE-expected2] depends on tests_calculatedvalues/test_leaseAdjCapEmp.py::test_leaseAdjCapEmp

I've read https://pytest-dependency.readthedocs.io/en/stable/scope.html and I assume I've done something wrong with naming the tests, but I can't work out what. To me the name "tests_calculatedvalues/test_leaseLiabilities.py::test_leaseLiabilities" seems like it should be correct.

I'm running into the same issue. pytest-dependency doesn't alter the execution order of files so, while it enforces the dependencies. PyTest still executes them in alphabetical order.

Yeah I plan to use pytest-ordering module to get past this limitation. Just haven't had a chance yet to write it into my tests

@tkedwards - you can you use pytest-order (a fork of pytest-ordering I created a few months ago) together with pytest-dependency. It has an option to order tests marked with dependency markers if needed. This way you won't lose the functionality from pytest-dependency (e.g. skipping skipped/failed tests) .

Thanks, I did end up using pytest-order
