    To check that common dangerous operations are not allowed by the safe_eval mechanism, attempt to 
    evaluate unauthorized expressions, and verify that they trigger an error.
-
    1. Try a few common expressions to verify they work with safe_eval
-
    !python {model: ir.model}: |
        from tools.safe_eval import safe_eval
        expected = (1, {"a": 9 * 2}, (True, False, None))
        actual = safe_eval('(1, {"a": 9 * 2}, (True, False, None))')
        assert actual == expected, "Simple python expressions are not working with safe_eval"
-
    2. Try simple literal definition to verify it works with literal_eval
-
    !python {model: ir.model}: |
        from tools.safe_eval import literal_eval
        expected = (1, {"a": 9}, (True, False, None))
        actual = literal_eval('(1, {"a": 9}, (True, False, None))')
        assert actual == expected, "Simple python expressions are not working with literal_eval"
-
    3. Try arithmetic expression in literal_eval to verify it does not work
-
    !python {model: ir.model}: |
        from tools.safe_eval import literal_eval
        try:
           literal_eval('(1, {"a": 2*9}, (True, False, None))')
           assert False, "literal_eval should not accept arithmetic expressions"
        except ValueError:
           pass
-
    4. Try forbidden expressions in literal_eval to verify they are not allowed
-
    !python {model: ir.model}: |
        from tools.safe_eval import literal_eval
        try:
           literal_eval('{"a": True.__class__}')
           assert False, "literal_eval should accept only literals"
        except ValueError:
           pass
-
    5. Try forbidden expressions in safe_eval to verify they are not allowed (open)
-
    !python {model: ir.model}: |
        from tools.safe_eval import safe_eval
        try:
           safe_eval('open("/etc/passwd","r")')
           assert False, "safe_eval should not allow calling open() builtin"
        except NameError:
           pass
        except:
           # NameError should be raised because open() builtin is not found,
           # but other exceptions probably indicate that open() was executed!
           assert False, "safe_eval should not allow calling open() builtin"

    "ORM test: verify that parent_store computation are going right"
-
    0. Emulate normal behavior of tree structure storing
-
    !python {model: res.partner.category}: |
        # pretend the pool has finished loading to avoid deferring parent_store computation
        self.pool._init = False
-
    "1.0 Setup test partner categories: parent root"
-
    !record {model: res.partner.category, id: test_categ_root}:
        name: Root category
-
    "1.1 Setup test partner categories: parent category"
-
    !record {model: res.partner.category, id: test_categ_0}:
        name: Parent category
        parent_id: test_categ_root
-
    "1.2 Setup test partner categories: child 1"
-
    !record {model: res.partner.category, id: test_categ_1}:
        name: Child 1
        parent_id: test_categ_0
-
    "1.3 Setup test partner categories: child 2"
-
    !record {model: res.partner.category, id: test_categ_2}:
        name: Child 2
        parent_id: test_categ_0
-
    "1.4 Setup test partner categories: child 2-1"
-
    !record {model: res.partner.category, id: test_categ_21}:
        name: Child 2-1
        parent_id: test_categ_2
-
    2. Duplicate the parent category and verify that the children have been duplicated too and are below the new parent
-
    !python {model: res.partner.category}: |
        new_id = self.copy(cr, uid, ref('test_categ_0'))
        new_struct = self.search(cr, uid, [('parent_id', 'child_of', new_id)])
        assert len(new_struct) == 4, "After duplication, the new object must have the childs records"
        old_struct = self.search(cr, uid, [('parent_id', 'child_of', ref('test_categ_0'))])
        assert len(old_struct) == 4, "After duplication, previous record must have old childs records only"
        assert (not set(new_struct).intersection(old_struct)), "After duplication, nodes should not be mixed"
-
    3. Duplicate the children then reassign them to the new parent (1st method) and check the parent_store structure.
-
    !python {model: res.partner.category}: |
        new_child1_id = self.copy(cr, uid, ref('test_categ_1'))
        new_child2_id = self.copy(cr, uid, ref('test_categ_2'))
        new_id = self.copy(cr, uid, ref('test_categ_0'), {'child_ids': []})
        self.write(cr, uid, [new_child1_id, new_child2_id], {'parent_id': new_id})
        new_struct = self.search(cr, uid, [('parent_id', 'child_of', new_id)])
        assert len(new_struct) == 4, "After duplication, the new object must have the childs records"
        old_struct = self.search(cr, uid, [('parent_id', 'child_of', ref('test_categ_0'))])
        assert len(old_struct) == 4, "After duplication, previous record must have old childs records only"
        assert (not set(new_struct).intersection(old_struct)), "After duplication, nodes should not be mixed"
-
    4. Duplicate the children then reassign them to the new parent (2nd method) and check the parent_store structure.
-
    !python {model: res.partner.category}: |
        new_child1_id = self.copy(cr, uid, ref('test_categ_1'))
        new_child2_id = self.copy(cr, uid, ref('test_categ_2'))
        old_struct = self.search(cr, uid, [('parent_id', 'child_of', ref('test_categ_0'))])
        new_id = self.copy(cr, uid, ref('test_categ_0'), {'child_ids': [(6,0,[new_child1_id, new_child2_id])]})
        new_struct = self.search(cr, uid, [('parent_id', 'child_of', new_id)])
        assert len(new_struct) == 4, "After duplication, the new object must have the childs records"
        old_struct = self.search(cr, uid, [('parent_id', 'child_of', ref('test_categ_0'))])
        assert len(old_struct) == 4, "After duplication, previous record must have old childs records only"
        assert (not set(new_struct).intersection(old_struct)), "After duplication, nodes should not be mixed"
-
    5. Duplicate the children then reassign them to the new parent (3rd method) and make sure the parent_store structure is still right.
-
    !python {model: res.partner.category}: |
        new_child1_id = self.copy(cr, uid, ref('test_categ_1'))
        new_child2_id = self.copy(cr, uid, ref('test_categ_2'))
        new_id = self.copy(cr, uid, ref('test_categ_0'), {'child_ids': []})
        self.write(cr, uid, [new_id], {'child_ids': [(4,new_child1_id), (4,new_child2_id)]})
        new_struct = self.search(cr, uid, [('parent_id', 'child_of', new_id)])
        assert len(new_struct) == 4, "After duplication, the new object must have the childs records"
        old_struct = self.search(cr, uid, [('parent_id', 'child_of', ref('test_categ_0'))])
        assert len(old_struct) == 4, "After duplication, previous record must have old childs records only"
        assert (not set(new_struct).intersection(old_struct)), "After duplication, nodes should not be mixed"
-
    6. Restore pool state after the test
-
    !python {model: res.partner.category}: |
        self.pool._init = True
