The following pattern is fairly common in other technologies:

  try {
    doSomethingRisky();
  } catch (Exception e) {
    logException(e);
    throw e;

By rethrowing the exception (assuming it’s not caught further up the call stack), the database transaction will be rolled back - that includes whatever insert or update ws triggered in logException(e). So how do we ensure that the logging occurs in a separate database transaction? The answer is a platform event!

Apex leaves much to be desired when it comes to mocking callouts to external services.

There must be a better way… Enter the HTTP Mock Registry.

Frustrated with messy tests and abstraction leaks, we’ve devised a utility that provides a intuitive interface for mocking callouts declaratively as well as a foundation for more modular test suites whenever callouts are involved.

While it’s nice that the Lightning Framework provides a way for Aura components to invoke Apex methods, the code required is a bit verbose. We can do better.

And let’s face it - the out-of-the-box Stub API provided in Apex is just plain awful. Here’s a lightweight utility I threw together to simplify mocking.
