... Cucumber calling an external ruby function from a step? In theory (Although I wouldn't advise this), you could make a new gem that allowed this behaviour. In that you're looking to do the exact thing we're looking to discourage here. From this 1-1 match, fire a new method (These are now 100% traceable and better than anything previously). Is it possible to pass a new step and or result that look like a step to cucumber layer, from the ruby code (which is part of step definition)? Farmer allows us to include human confirmation into our normal testing flow. They are about as simple as they can be while still being practical. citations from another source. When Cucumber executes a Gherkin step in a scenario, it will look for a matching step definition to execute. 1. Which will be done at some point during the v4 lifecycle I imagine. If you want further reading, check a lot of the aruba library between around 0.11 and 0.14.1 and then compare it to 0.14.11 and 1.0.pre versions. The more they learn about the problem and the domain, the more natural the division will be. I understand that we’re both getting a bit frustrated here, but at this point I’m no wiser than when I started this discussion as to how to achieve my goal without step. I have a feeling we’re talking past each other in this regard, because you keep suggesting solutions that are not relevant to my use case, and you have made several guesses about my use case that have nothing to do with anything I’ve said about it. So my earlier comments that were ignored I now realise were done either accidentally or because you disagree with them (Which is fine). If the feature goes away, I won’t want to stop using Cucumber, but I may well have no choice, if at that point Cucumber will no longer be adequate for my purposes. We are not advocating for one minute that our way is the only way or the highway. If step is removed from Cucumber, I think adding it back in a plugin will be my only option if I want to continue using Cucumber. Once transformed, map this text and call your new functionality, either using, If you're looking to pass a block through the caller chain, then the block must be defined in your steps. That being the case, I don’t see how send would be helpful, unless you’re thinking of using method_missing to deal with receiving Gherkin text as a message... ...and if you are, then once again we need to map from Gherkin text to step definition, and so we’re right back to needing the step method. This page describes tools for a Ruby or Ruby on Rails environment. Calling Steps from Step Definitions It can be described in the following steps − Cucumber reads the code written in plain English text (Language Gherkin – to be introduced later in this tutorial) in the feature file (to be introduced later). I'm not going to comment on this any more, because I feel I've tried in a few different ways to explain in quite good detail what to do. Also I would advocate having one "mega-step", that does 10 different things, and actually have 10 small steps, even if portions are re-used. Relish helps your team get the most from Behaviour Driven Development. It is not relevant to my question, because (1) I have never found debugging these steps to be a problem and (2) as far as I can tell, those abstractions do not provide me what I need here. You could then call your steps based on the step_text so you just send call them. My thought was I’d rather not suddenly get deprecation warnings on a minor or patch upgrade. If such a mapping exists, the function is Helpers::ReUsableSteps.step_two @enkessler I believe I’m using this feature in a way that is not actually representative of the antipatterns that it’s often associated with. Essentially the methodology you have of having a "master step" which then delegates to a multitude of other steps is something I would disuade in most circumstances, it's too hard to triage, too taxing for newcomers and relies heavily on almost a bus-factor style approach where a few siloed team members know everything. There is an OpenCollective account visible here: https://opencollective.com/cucumber. If you wish to continue writing 1 'mega-step' this is not too dissimilar to my original POV which was that I had "worked at a company with 1 step that called 5 steps", because in essence you have something similar to that in your codebase, just a bit more varied (Steps that can either perform actions or assert instead of steps that combine other steps which do actions). But short of doing the work for you (Which I'm sure you'd expect, would be perhaps crossing a line), you need to perhaps spike a few different solutions for yourself. But if not I suggest doing some reading into some of the points, checking out the code areas I've suggested or maybe (Ability in other languages not known), checking Java or other versions of cucumber to see how other people have conquered this issue (It's not just a ruby issue). Here are some guidelines that will lead to better scenarios. If you are very experienced with Ruby, then you should know that using language specific abstractions, such as Helpers, Classes and more indepth stuff such as Singletons or Anonymous classes, all come with large stacktraces and good debugging tools. This is the part for which I am once again asking for a suggestion, or recommending that step be taken off the deprecation list. Publish, browse, search, and organize your Cucumber features on the web. Also that in order to maintain this abstraction, it provides the user with no discernable benefits, and just a mountain of issues. Our laser focus on a single technology has made us a leader in this space. One way to split the steps may be according to the domain concept they work on. Each step definition must be tied to each scenario defined in… What **not** to put in step definitions? aslak also put a quite clean JS code-snippet, and I've put a reasonably concise ruby snippet. The Gherkin step definitions already provide a perfectly suitable translation. Your step_text is simply a capture. I'm not keen on this backwards and forwards motion because it's all theoretical, could you maybe have a go at doing it, or perhaps illustrate with a git repo why it wouldn't work. Here as I see it you have a simple choice (Both are valid options). When refactoring a sequence of steps to a new, more descriptive step, you can use the steps method and Ruby's %-notation like this: This way you can simply copy the steps over without any changes. Warning: Apparently, steps processes its argument with the Gherkin parser, meaning only lines starting with the Gherkin keywords Given/When/Then/And/But will be considered. hash options), etc. It's like a poor man's implementation of subroutines (which all languages support natively) with the following drawbacks: The XXX link should point to a page in the documentation explaining in more details how to use fiunctions/methods with Cucumber. Posted over 8 years ago. Learn to structure large Ruby on Rails codebases with the tools you already know and love. I think I've landed on the crux of the issue. Some requirements are simple for a human to confirm, but are very difficult to assert using automation. Some of these companies (Such as CodeFirst), https://opencollective.com/codefirst actively contribute to the maintenance of cucumber, and as such if they had a request it could perhaps be prioritised dependent on needs e.t.c. We are not advocating for one minute that our way is the only way or the highway. Am I wrong? It is an object-oriented language. with hard-coded strings), but not mine. Obviously I've made up a long namespace to illustrate it could be whatever. :). Everyone who works on cucumber are volunteers. It would work, because you're assuming you have to send a step which has spaces in, but you could sanitize that. :). I should see "foo"), not a Ruby method name (e.g. Relish helps your team get the most from Behaviour Driven Development. When Cucumber executes a Gherkin step in a scenario, it will look for a matching step definition to execute. If you want to combine several actions into one step, extract individual (helper) methods and call these methods from your step definition. For a better alternative, follow this link: XXX The XXX link should point to a page in the documentation explaining in more details how to use fiunctions/methods with Cucumber. Your step_text is simply a capture. I explained why the new technology was better, by alluding to stacktraces, as well as the fact it uses the MRI under the hood, instead of having cucumber replicate that. To illustrate how this works, look at the following Gherkin Scenario: IDEs RubyMine. You need to tell us why it is better. If you’d like to see it in action, take a look at https://github.com/marnen/erogatio/blob/master/features/step_definitions/web_steps.rb#L27 and https://github.com/marnen/erogatio/blob/master/features/enter_payment_for_work_units.feature#L20. I don’t want to do that unless I can’t avoid it, though, and so I’d really welcome other ideas. The reason it is being deprecated is as aslak has previously mentioned and is linked to in a couple of articles (As well as the notional lack of it now in all other major cucumber flavours). You signed in with another tab or window. Then if another workable solution is not provided, I’ll either have to abandon Cucumber at that time (which would be a huge pity) or maintain my own fork or plugin (which I really don’t want to put the time into doing). As far as I can tell, this is exactly on topic for that. Cucumber finds the Step Definition file with the help of the … But from your use cases and the direction you've been moving in, I'm not sure I'm the best person to help, as it seems as if the reason for you wanting to code in a specific way without using a better methodology may be better answered with a holistic company-based query (Which Seb is much more qualified and experienced than I). , which is an arduous task I admit, but sometimes in tests, less-DRY is better I...
