  • Mutation testing on a third directory, and a worse score

    Note2 min read

    A technique applied to a third directory, with a score of thirty-eight per cent and a good reason. A low score on code whose correctness is asserted at…

  • PSR-3 context, and the field that was finally queried

    Note2 min read

    A structured logging field added in 2023, never queried, and the one week it was the only thing that helped. A field with no queries against it for…

  • The value object library, five years on

    Deep dive10 min read

  • A readonly class that survived a requirements change

    Note2 min read

    A value object made readonly in 2022, and the requirement in 2026 that would have broken a mutable one. The property that mattered was not thread safety or…
