What you will learn

  • Design clean public interfaces and truthful error propagation.
  • Validate data locally while identifying untested engine boundaries.

  1. Design pipeline binding and processing contracts

    Connect parameter metadata, by-value/by-property binding, collection enumeration, and begin/process/end behavior in advanced functions.

    Start learning

  2. Handle errors and native exit status deliberately

    Separate terminating exceptions, non-terminating errors, preferences, catch behavior, and native-process results without treating a clean console as success.

    Start learning

  3. Design streams and clean machine output

    Separate success objects, errors, warnings, verbose/debug/information messages, progress, and native redirection behavior.

    Start learning

  4. Package modules with explicit public interfaces

    Separate module discovery, import effects, exported members, manifests, dependency versions, and platform compatibility.

    Start learning

  5. Build typed data and API boundaries

    Separate parsing, request construction, transport, authentication, status, schema validation, and retry semantics using offline fixtures.

    Start learning

  6. Test public behavior with isolated fixtures

    Separate parsing, model checks, PowerShell runtime tests, module dependencies, and effectful integration while protecting output and failure contracts.
