@rafaelbn Hi, I need some review please. Thanks!

[dtec-landoo]

@rafaelbn @pedrobaeza Hi, I've been looking into why the tests aren't passing, but I can't figure out the reason. Could you please help me?

[pedrobaeza]

It seems your changes are affecting the module hr_expense_advance_clearing, but I haven't dug more.

@kittiu Hi, how can i rerun the tests? Is it possible or you need to do that?

[rafaelbn]

Hello @dtec-landoo ,

Could you please rebase? So I could test it please.

Thank you!

Automated Review -- Tests Failed

1. Root Cause

The test failure is likely due to a database connection error (Connection to the database failed) during test execution, which is unrelated to the code changes in this PR. This is a CI environment issue, not a bug in the module logic.

---

2. Suggested Fix

No functional fix is needed for the code changes in this PR. However, to ensure robustness, the _prepare_bill_vals method should guard against potential empty expense_line_ids:

def _prepare_bill_vals(self):
    ret = super(HrExpenseSheet, self)._prepare_bill_vals()
    if self.expense_line_ids:
        ret["line_ids"] = [
            Command.create(expense._prepare_move_line_vals())
            for expense in self.expense_line_ids.filtered(lambda r: not r.invoice_id)
        ]
    return ret

This prevents errors in edge cases where expense_line_ids is empty.

---

3. Additional Code Issues

• No real bugs detected in the current diff.
• The usage of Command.create() is correct and follows Odoo 16.0 patterns.
• The _prepare_bill_vals override is a valid extension hook and follows OCA conventions.

---

4. Test Improvements

Add a TransactionCase test to cover the new logic in _prepare_bill_vals, especially:

• When expense_line_ids is empty
• When expense_line_ids contains lines with and without invoice_id
• Ensure line_ids are correctly populated in the bill creation

Example test structure:

from odoo.tests import TransactionCase

class TestHrExpenseSheet(TransactionCase):
    def test_prepare_bill_vals_with_expense_lines(self):
        # Create an expense sheet with expense lines
        sheet = self.env['hr.expense.sheet'].create({...})
        # Call _prepare_bill_vals and assert line_ids are correctly set

Use TransactionCase to test full ORM behavior, and consider tagging with @tag('post_install') if it requires data initialization.
