Enable failing test for main branch

Steps

1. Identify the failing test

• Locate the test file test_dtensor_ops.py and the specific test method test_unbacked_dtensor_op_db_nanmean_cpu_float32.
• Verify that the test is failing on the main branch.

2. Update the test configuration

• In the test configuration file (e.g., tests/test_dtensor_ops.py), add a skip parameter to the test method:

import unittest

class TestUnbackedDTensorOpsCPU(unittest.TestCase):
    def test_unbacked_dtensor_op_db_nanmean_cpu_float32(self):
        # test implementation
        pass

    @unittest.skip("Failing test, re-enable when fixed")
    def test_unbacked_dtensor_op_db_nanmean_cpu_float32(self):
        # test implementation
        pass

• Alternatively, you can use a test framework like pytest and use the @pytest.mark.skip decorator:

import pytest

@pytest.mark.skip(reason="Failing test, re-enable when fixed")
def test_unbacked_dtensor_op_db_nanmean_cpu_float32():
    # test implementation
    pass

3. Re-enable the test

• Remove the skip parameter or the @pytest.mark.skip decorator from the test method.

4. Verify the test

• Run the test again and verify that it passes.
• If the test still fails, investigate the issue and fix the underlying problem.
