Answer 1

The fields you use in attrs need to be present in the current view.
You can add this field to model:
class test_rule(models.Model):
_name = 'test.rule'
rule_id = fields.Many2one('test.list', required=True)
type_test = fields.Selection(related='rule_id.type_test')
ul = fields.Many2one('product.ul', string='Package Logistic Unit')
And then to your form:
<form string="Test Rules">
<field name="type_test" invisible="1"/>
<field name="ul" attrs="{'invisible': [('type_test', '!=', 'A')]}"/>
</form>
