Replace @pytest.mark.order with fixtures and finalizers for E2E tests

[Copilot]

Summary

Refactored E2E tests to use pytest fixtures with finalizers instead of @pytest.mark.order decorators, addressing the issue raised in #366 about managing test order numbers manually.

Problem

The E2E test suites (online_tests.py and language_tests.py) were using @pytest.mark.order decorators with numeric values (1-21) to control test execution order. This approach had several limitations:

• Required manual management of order numbers across 59 test methods
• Made it difficult to add new tests without renumbering existing ones
• No automatic cleanup if tests failed midway
• Cleanup tests (orders 19-21) had to be manually scheduled at the end
• Required the pytest-order dependency

Solution

Replaced explicit ordering with pytest fixtures that handle setup and teardown automatically:

Fixtures Created (with finalizers for cleanup)

online_tests.py:

• login_session() - Auto-runs before all tests
• site_users(login_session) - Creates/deletes test users
• test_group(site_users) - Creates/deletes test group
• test_projects(login_session) - Creates/deletes test projects

language_tests.py:

• login_all_languages() - Tests login in all languages
• site_users(login_all_languages) - Creates/deletes test users
• test_group(site_users) - Creates/deletes test group
• test_projects(login_all_languages) - Creates/deletes test projects

Example Conversion

Before:

@pytest.mark.order(8)
def test_create_projects(self):
    self._create_project(project_name)
    # ...

@pytest.mark.order(10)
def test_delete_projects(self):
    self._delete_project(project_name)
    # ...

@pytest.mark.order(11)
def test_list_projects(self):
    self._list("projects")

After:

@pytest.fixture(scope="module")
def test_projects(login_session):
    """Create test projects and clean up after."""
    create_project(project_name)
    # ...
    yield
    # Cleanup happens automatically
    delete_project(project_name)
    # ...

def test_list_projects(self, test_projects):
    # Projects automatically created before test runs
    # and deleted after all tests complete
    self._list("projects")

Changes

• ✅ Removed 59 instances of @pytest.mark.order decorators
• ✅ Created 8 fixtures (4 per file) with finalizers for automatic cleanup
• ✅ Updated 51 test methods to use fixture parameters
• ✅ Removed pytest-order dependency from pyproject.toml

Benefits

1. Automatic cleanup - Finalizers ensure resources are deleted even if tests fail
2. Explicit dependencies - Each test declares what it needs via fixture parameters
3. No manual ordering - No need to assign/manage numeric order values
4. Scalable - Can add unlimited tests without worrying about renumbering
5. Standard pattern - Uses pytest's recommended approach for setup/teardown
6. Better maintainability - Clear separation of setup, test, and teardown phases

Testing

• All modified test files pass Python syntax validation
• Fixtures follow pytest best practices with proper scope and dependency chains
• Cleanup logic preserved from original teardown tests

<issue_title>Does pytest have a teardown concept? Consider using it so these mark orders don't have to get increased if we ever had more than 30 actual tests. Maybe @pytest.fixture with a finalizer?</issue_title>

if you delete the default project you do not need to also delete the child projects

[jacalata]

We still need ordered tests because e.g. this test must take place after test_users_add_to_group

[jacalata]

the publishing test must be run after projects are created but before any get tests

[jacalata]

wb_delete and ds_delete must run after the get, extract and export tests

[jacalata]

suggestion from Andy: Consider also adding a "before all" setup step that deletes all workbooks and datasources that exist on the site that match the "publishable" name pattern. Currently if you stopped the tests mid-way through execution, they'd never get deleted.
