Migrate from Protractor to Cypress automation test framework - protractor

I'm just starting to look into the amount of work it would take to convert a lot of existing Protractor e2e code/tests to Cypress. Has anyone done this and is there an efficient way to do this without rebuilding all of the code from scratch within Cypress?
Just for a little background, the existing Protractor e2e framework was written in Typescript and uses the Page Object Model design pattern along with object oriented programming concepts -
Each UI screen of the AUT has its own class and members (i.e. class CustomerInfo would have firstName field and it's element locator.
There are classes for each type of UI element (i.e. text input, dropdown, checkbox).
These classes contain methods that encapsulate actions available for the UI element type (i.e. methods within text input class would be - setText, verifyText, clearText, verifyIsEnabled, etc...)
For example, the Protractor e2e test step would look something like:
it("example test case", () => {
testPage.pageSection.firstName.setText("John");
});
Any ideas on how to migrate from Protractor to Cypress would be extremely helpful.
Thanks!

Can I build a compiler plugin with a post processor to generate code from previous collected derived structs?

As far as I know current usage for compiler plugin is to define the attribute for compiler to recognize and then the compiler will invoke the code defined and registered in the plugin.
I am thinking if it is possible to build a compiler plugin that have a post processor. I can some how first register the structs encountered by proc_macro_derive in a data structure within the plugin, then the post processor can generate code according to the plugin data structure populated before.
My intention is to generate a symbol table form derived structs, so I can do some experiment for dynamic typing in rust. I am not sure if it is possible to achieved in compile time without manually register them one by one in runtime.

Should I simulate FE request in Functional Testing in TYPO3?

I'm trying to understand concepts of Functional Testing in a scope of TYPO3 and overall.
My intention is to test Controller of my extension. For simplicity let's imagine, that it has only two methods: listAction() and addAction($object).
I've checked some Core tests and one of them was EnableFieldsTest from Extbase, which does following: loads some special crafted extension, simulates FE (via special JsonRenderer.ts), which calls listAction() of that extension and the output (specail JSON) is examined then.
So, I decided to do same with my Controller, simulated FE, which called my listAction(). The only difference is that my extension doesn't use JSON View, but usual Fluid, which produces HTML.
To make it work as expected I need either:
Make significant changes in my extension, so it outputs JSON in Testing context, but this seems kinda hacky for me.
Do not use provided HasRecordConstraint from the Core, but simply examine HTML, that was output with assertContains(), which also seems hacky.
Create customized version of my extension, which outputs expected JSON and use it only as Fixture. But this makes such test useless at all.
Therefore I'm stuck at this point and need to understand:
Is it right to simulate FE request, like I do, or I'm now out of Functional Testing concept?
In case I want to test object creation via addAction($object) and ensure, that f.e. a request to a REST service is made, should I stub that Service or I can catch a call somehow different?
Since TYPO3 8, acceptance tests are integrated which are more the thing you want to have.
Use functional tests to call the action and check the return value of that but don't use a frontend
Use acceptance tests to call the frontend and check the HTML output of your plugin.
The best would be to check out the acceptance tests of the core.

How can I write a code generator in Ceylon

I want to write a code generator that generates a class based on the meta model of another ceylon class. I want the code generator to run at compile time. What is the best way for me to do this. I could probably accomplish this by writing a plugin for gradle or the ceylon build system but I'm hoping for a simpler solution. Unfortunately, I don't see any support for code generators in ceylon. Also, are there any plans for code generators in ceylon?
I want to write this code generator because I'm thinking about writing a simple web framework for ceylon that look at a class like the following using the meta-model:
controller
shared class Controller() {
shared void doSomething() => print("did it!");
}
I plan for it to be like Spring MVC. This framework would make a restful API from the Controller class that allows someone to write an AJAX call like this:
$http.get("/Controller/doSomething");
I want to make things more convenient, high level, and simple by doing something like GWT. I want to create a code generator that automatically generates a class like this:
shared class RemoteController() {
shared void doSomething() {
$http.get("/Controller/doSomething");
}
}
The RemoteController would be run in a user's browser as javaScript and allow client side ceylon code to do an Ajax call like this:
RemoteController().doSomething();
That would end up calling the Controller().doSomething() on the server so "did it!" would be printed.
AST Transformers have been proposed, but are still in the early design phase. For now, to do compile-time code generation, you’ll have to rig up something of your own.
To actually generate the code, I would recommend use of ceylon.ast and ceylon.formatter. The workflow would roughly be:
analyze source code –
either parse it with ceylon.ast (ceylon.ast.redhat::compileAnyCompilationUnit) and analyze it without typechecking,
or parse it using the compiler, run the typechecker, then convert it to ceylon.ast (ceylon.ast.redhat::anyCompilationUnitToCeylon), keeping the typechecker information using the new update hooks in the very soon upcoming 1.2.0 release
edit the source code AST to add your new code (using a custom ceylon.ast.core::Editor that injects new class definitions into the CompilationUnits), or perhaps create entirely new compilation units if the RemoteController lives in a different module
convert the ceylon.ast AST to a compiler AST and feed it into ceylon.formatter to turn the AST into code again (see here for an example of that)
Alternatively, if you integrate this into your build step, you could skip the ceylon.formatter part of step 3 and instead feed the converted compiler AST into the typechecker and rest of the compiler directly.

ELKI: Implementing a custom ResultHandler

I need to implement a custom ResultHandler but I am confused about how to actually integrate my custom class into the software package.
I have read this: http://elki.dbs.ifi.lmu.de/wiki/HowTo/InvokingELKIFromJava but my question is how are you meant to implement a custom result handler such that it shows up in the GUI?
The only way I can think of doing it is by extracting the elki.jar package and manually inserting my custom class into the source code, and then re-jarring the package. However I am fairly sure this is not the way it is meant to be done.
Also, in my resulthandler I need to output all the rows to a single text file with the cluster that each row belongs to displayed. How tips on how I can achieve this?
There are two questions in here.
in order to make your class instantiable by the UIs (both MiniGUI and command line), the classes must implement our Parameterization API. There are essentially two choices to make your class instantiable:
Add a public constructor without parameters (the UI won't know how to set your parameters!)
Add an inner static class Parameterizer that handles parameterization
in order to add your class to autocompletion (dropdown menu), the classes must be discovered by the MiniGUI/CLI/other UIs. ELKI uses two methods of discovery:
for .jar files, it reads the META-INF/elki/interfacename service files. This is a classic service-loader approach; except that we also allow ordering instances.
for directories only, ELKI will also scan for all .class files, and inspect them. This is mostly meant for development time, to avoid having to update the service files all the time. For performance reasons, we do not inspect the contents of .jar files; these are expected to use service files.
You do not need your class to be in the dropdown menu - you can always type the full class name. If this does not work, adding the name to the service file will not help either, but ELKI can either not find the class at all, or cannot instantiate it.
There is also a tutorial on implementing a custom result handler, but it does not discuss how to add it to the menu. In "development mode" - when having a folder with .class files - it will show up automatically.

How do I associate a CoffeeScript file with a view?

Just installed rails 3.1 rc1 and am trying to grok the best way to manage javascript with the new asset pipeline
By default all coffeescript is compiled into a single application.js file, this is a good thing.
Each seperate coffee script file is appended to the js file and wrapped in an anonymous function which is executed via the call method
A common scenario would be to use some jquery to turn various forms into ajax forms, update UI, etc...
Many of these scripts will be specific to a controller or action, I am trying to grok the 'conventional' way to handle this,
since everything is wrapped in an anonymous function how do I only execute just
the code for a particular controller / action, by default all of the anonymous functions are being executed
I did play around with some hacks where I load the controller and action name into js variables and then in
coffeescript check those to conditionally run code, I don't like that very much
my initial thought was that each coffee file would contain a js namespace/object and I would call the specific ones from the view,
going to spike this using the default_bare = true configuration
see How can I use option "--bare" in Rails 3.1 for CoffeeScript?
EDIT
Looking around some more: this looks like it might be the correct approach - "Can't find variable" error with Rails 3.1 and Coffeescript
There are two common approaches:
Make behavior conditional on the presence of a particular element. For instance, code to run a signup sheet should be prefaced with something like
if $('#signup').length > 0
Make behavior conditional on a class on the body element. You can set the body class using ERB. This is often desirable for stylesheets as well. The code would be something like
if $('body').hasClass 'user'
gistyle is a simple gem that helps you running action-specific javascript codes.
By following its setup, you set some data attributes in your body element, representing the current controller and action names. Then it will only call that action when the corresponding view is loaded.
