Thanks for the PR! The CI failed due to two issues:

1. Duplicate TestAlerts class - You added a new TestAlerts class, but one already exists at line 441. Please merge your new tests into the existing TestAlerts class instead of creating a duplicate.

2. Missing newline at end of file - The file needs a trailing newline at the end.

To fix:

1. Remove the duplicate class TestAlerts: definition (the one you added around line 504)
2. Move your three new test methods ( est_alerts_returns_list, est_alerts_requires_auth, est_alerts_empty) into the existing TestAlerts class (around line 441)
3. Ensure the file ends with a newline

Once fixed, the CI should pass. Let me know if you need help!

The CI is still failing with two issues:

1. Duplicate TestAlerts class - The diff shows you're adding a new class TestAlerts: at line 446, but one already exists at line 441. You need to merge your three new test methods into the existing TestAlerts class instead of creating a duplicate.

2. Trailing whitespace - Line 494 has trailing whitespace: assert data["count"] == 0\n (has spaces after the newline)

To fix:

1. Remove the duplicate class TestAlerts: definition you added
2. Move your three new test methods (test_alerts_returns_list, test_alerts_requires_auth, test_alerts_empty) inside the existing TestAlerts class (around line 441, after test_alerts_list)
3. Remove trailing whitespace on the line assert data["count"] == 0

Once fixed, push and CI should pass.
