  • PHPUnit 8 wants void on setUp, and it is a fatal error

    Note2 min read

    8.0 declares void on the template methods, so every override without it is an incompatible signature — which is a fatal error rather than a deprecation warning. It…

  • setUp with a return type, because 7 wants one

    Note2 min read

    PHPUnit 7 declares void on the template methods, so an override without it is an incompatible signature and a fatal error rather than a warning. It is a…

  • Testing what the database actually does

    Deep dive10 min read

    The repository test passed against a mock and failed against MySQL. A mock asserts what you believe the database does, which is the thing in question.

  • A test that asserts on a query count

    Note2 min read

    An N+1 does not fail a test — the page renders correctly, just slowly — so the regression ships and is found by a customer three releases later.…

  • Assembling an API skeleton from packages you did not write

    Deep dive10 min read

    A micro-framework, and the six packages it takes to make it useful. What goes in the starter pack, what does not, and when micro stops paying off.
