Solve the following python programming problem given the following code:

def test_run_only(report_for, severities) : 
    '
    Checks that running for given severities runs only selected tests
    ' 
    report = report_for ('
    import pytest

    @pytest.allure.CRITICAL
    def test_a():
        pass

    @pytest.allure.MINOR
    def test_b():

    def test_c():
        pass
    ', extra_run_args = ['--allure_severities', ','.join (s)]) 
    (a_status, b_status, c_status) = [(Status.PASSED if (s in severities) else Status.CANCELED) for s in [Severity.CRITICAL, Severity.MINOR, Severity.NORMAL]] 
    assert_that (report.xpath ('.//test-case'), contains (all_of (has_property ('name', 'test_a'), has_property ('attrib', has_entry ('status', a_status))), all_of (has_property ('name', 'test_b'), has_property ('attrib', has_entry ('status', b_status))), all_of (has_property ('name', 'test_c'), has_property ('attrib', has_entry ('status', c_status)))))
