- BerislavLopac 8y agoThis is precisely a symptom of unclear ownership responsibilities.
- AnimalMuppet 8y agoNo, it can be an issue of it being unclear in which component the bug actually is.
- BerislavLopac 8y agoWhich is a clear sign that your components are not sufficiently separate.
- AnimalMuppet 8y agoUm, no. The real world is not that simple. It would be nice if it were. Or perhaps your statement is correct, but in the real world components are never sufficiently separate. So, while your statement may be correct by definition, it is not useful.
- james_s_tayler 8y agoI think you really nailed it with this one. I can imagine there being a normal distribution of 'separateness' of software and the rare top tail-end of the distribution gets it perfectly right, most are in the middle somewhere between 'service oriented architecture' and 'ball of mud' and some are just at plain ball of mud.
- BerislavLopac 8y agoYou are misreading my words.
- AnimalMuppet 8y agoPerhaps so. Would you care to explain? Your statement here doesn't give me much to go on.
- BerislavLopac 8y agoWell I meant it quite literally: if it is not clear which component has the bug, the components are not separate enough. You also say: > in the real world components are never sufficiently separate But the separation of components is not an issue of "real world", it is a function of design and implementation. It is absolutely to the developers how independently the components will be implemented; if there is no way to test them in isolation, then they are not really separate components. Take this website, and your browser, as an example. They are obviously connected, as you're using the latter to access the former, but they are completely independent: you can access other pages with the browser, and you can use other methods (other browsers, or curl, or Postman etc) to access this page. Each can be tested separately, and even when they are used in conjunction they don't directly depend on each other, but rather on a set of standards (HTTP, HTML, CSS etc) understood by both.
- AnimalMuppet 8y agoYes, but then you find web pages that attempt to determine which kind of browser requested the page, and changes what is sent back in order to work around the broken-ness of specific browsers. Yes, it's supposed to be a nice clean interface specified by standards. But in the real world, as they say, all abstractions leak. "All" may be an overstatement, but the problem is real. We never separate things cleanly enough.
- BerislavLopac 8y agoThis statement is true, depending on how you define "enough".
