There were 2 warnings:

1) App\Tests\Api\Status\GitHubStatusApiTest::testSetIssueStatusRemovesExcessStatuses
The at() matcher has been deprecated. It will be removed in PHPUnit 10. Please refactor your test to not rely on the order in which methods are invoked.

2) App\Tests\Api\Status\GitHubStatusApiTest::testSetIssueStatusRemovesUnconfirmedWhenBugIsReviewed
The at() matcher has been deprecated. It will be removed in PHPUnit 10. Please refactor your test to not rely on the order in which methods are invoked.
