  • Data providers run before setUp, every time

    Note1 min read

    A provider that builds its cases from something created in setUp() fails with a null, because every provider in the class runs before any test does — including…

  • list() with keys unpacks an associative row

    Note1 min read

    Destructuring only worked positionally, so a row fetched as an associative array had to be unpacked by hand — three assignments and a typo waiting to happen. A…

  • withoutOverlapping on a scheduled command

    Note1 min read

    A scheduled task that occasionally runs longer than its interval will be started again while the first is still going, which for an import means two processes writing…

  • Queue retry_after and the job that runs twice
