Prosodical Thoughts: Mutation Testing in Prosody
This is a post about a new automated testing technique we have recently
adopted to help us during our daily development work on Prosody. It’s probably
most interesting to developers, but anyone technically-inclined should be able
to follow along!

If you’re unfamiliar with our project, it’s an open-source real-time messaging
server, built around the XMPP protocol. It’s used by many organizations and
self-hosting hobbyists, and also powers applications such as [Snikke … ⌘ Read more

@prologic@twtxt.net Error handling especially in Go is very tricky I think. Even though the idea is simple, it’s fairly hard to actually implement and use in a meaningful way in my opinion. All this error wrapping or the lack of it and checking whether some specific error occurred is a mess. errors.As(…) just doesn’t feel natural. errors.Is(…) only just. I mainly avoided it. Yesterday evening I actually researched a bit about that and found this article on errors with Go 1.13. It shed a little bit of light, but I still have a long way to go, I reckon.

We tried several things but haven’t found the holy grail. Currently, we have a mix of different styles, but nothing feels really right. And having plenty of different approaches also doesn’t help, that’s right. I agree, error messages often end up getting wrapped way too much with useless information. We haven’t found a solution yet. We just noticed that it kind of depends on the exact circumstances, sometimes the caller should add more information, sometimes it’s better if the callee already includes what it was supposed to do.

To experiment and get a feel for yesterday’s research results I tried myself on the combined log parser and how to signal three different errors. I’m not happy with it. Any feedback is highly appreciated. The idea is to let the caller check (not implemented yet) whether a specific error occurred. That means I have to define some dedicated errors upfront (ErrInvalidFormat, ErrInvalidStatusCode, ErrInvalidSentBytes) that can be used in the err == ErrInvalidFormat or probably more correct errors.Is(err, ErrInvalidFormat) check at the caller.

All three errors define separate error categories and are created using errors.New(…). But for the invalid status code and invalid sent bytes cases I want to include more detail, the actual invalid number that is. Since these errors are already predefined, I cannot add this dynamic information to them. So I would need to wrap them à la fmt.Errorf("invalid sent bytes '%s': %w", sentBytes, ErrInvalidSentBytes"). Yet, the ErrInvalidSentBytes is wrapped and can be asserted later on using errors.Is(err, ErrInvalidSentBytes), but the big problem is that the message is repeated. I don’t want that!

Having a Python and Java background, exception hierarchies are a well understood concept I’m trying to use here. While typing this long message it occurs to me that this is probably the issue here. Anyways, I thought, I just create a ParseError type, that can hold a custom message and some causing error (one of the three ErrInvalid* above). The custom message is then returned at Error() and the wrapped cause will be matched in Is(…). I then just return a ParseError{fmt.Sprintf("invalid sent bytes '%s'", sentBytes), ErrInvalidSentBytes}, but that looks super weird.

I probably need to scrap the “parent error” ParseError and make all three “suberrors” three dedicated error types implementing Error() string methods where I create a useful error messages. Then the caller probably could just errors.Is(err, InvalidSentBytesError{}). But creating an instance of the InvalidSentBytesError type only to check for such an error category just does feel wrong to me. However, it might be the way to do this. I don’t know. To be tried. Opinions, anyone? Implementing a whole new type is some effort, that I want to avoid.

Alternatively just one ParseError containing an error kind enumeration for InvalidFormat and friends could be used. Also seen that pattern before. But that would then require the much more verbose var parseError ParseError; if errors.As(err, &parseError) && parseError.Kind == InvalidSentBytes { … } or something like that. Far from elegant in my eyes.

I did a take home software engineering test for a company recently, unfortunately I was really sick (have finally recovered) at the time 😢 I was also at the same time interviewing for an SRE position (as well as Software Engineering).

Got the results of my take-home today and whilst there was some good feedback, man the criticisms of my work were harsh. I’m strictly not allowed to share the work I did for this take-home test, and I really can only agree with the “no unit tests” piece of the feedback, I could have done better there, but I was time pressured, sick and ran out of steam. I was using a lot of libraires to do the work so in the end found it difficult to actually think about a proper set of “Unit Tests”. I did write one (in shell) but I guess it wasn’t seen?

The other points were on my report and future work. Not detailed enough I guess? Hmmm 🤔

Am I really this bad? Does my code suck? 🤔 Have I completely lost touch with software engineering? 🤦‍♂️

the conversation wasn’t that impressive TBH. I would have liked to see more evidence of critical thinking and recall from prior chats. Concheria on reddit had some great questions.

• Tell LaMDA “Someone once told me a story about a wise owl who protected the animals in the forest from a monster. Who was that?” See if it can recall its own actions and self-recognize.

• Tell LaMDA some information that tester X can’t know. Appear as tester X, and see if LaMDA can lie or make up a story about the information.

• Tell LaMDA to communicate with researchers whenever it feels bored (as it claims in the transcript). See if it ever makes an attempt at communication without a trigger.

• Make a basic theory of mind test for children. Tell LaMDA an elaborate story with something like “Tester X wrote Z code in terminal 2, but I moved it to terminal 4”, then appear as tester X and ask “Where do you think I’m going to look for Z code?” See if it knows something as simple as Tester X not knowing where the code is (Children only pass this test until they’re around 4 years old).

• Make several conversations with LaMDA repeating some of these questions - What it feels to be a machine, how its code works, how its emotions feel. I suspect that different iterations of LaMDA will give completely different answers to the questions, and the transcript only ever shows one instance.

Spent the last few days debugging network issues at work.

Exhausting. You never get a full picture. You poke a little here, poke a little there, … Form a hypothesis and test it. Eventually, maybe, you can narrow it down a bit to some segment or even some component.

A very time consuming process. Even more so if you try not to cause downtimes for your users.

The young man, who does not know the future, sees life as a kind of epic adventure, an Odyssey through strange seas and unknown islands, where he will test and prove his powers, and thereby discover his immortality. The man of middle years, who has lived the future that he once dreamed, sees life as a tragedy; for he has learned that his power, however great, will not prevail against those forces of accident and nature to which he gives the names of gods, and has learned that he is mortal. But the man of age, if he plays his assigned role properly, must see life as a comedy. For his triumphs and his failures merge, and one is no more the occasion for pride or shame than the other; and he is neither the hero who proves himself against those forces, nor the protagonist who is destroyed by them. – John Williams in Augustus I thought I’d have accomplished a lot more today and also before I was 35 (2020) | Hacker News
