Is it possible to compare two images using Robot Framework? I tried one solution using OpenCV that compares two images, but it's getting difficult to write something specific to Robot Framework.
Robot framework itself doesn't have any such feature. However, it's possible to write a custom keyword to do it. I worked on a team a few years ago that built some keywords based on the ImageMagick library. You can either have the keywords import the imagemagick library itself, or use the imagemagick cli.

I'm trying to define a custom QT Slot/Signal for passing a QImage.
I'm using qt_widgets crate which has many predefined slot types like SlotOfQIcon. However it doesn't have one for QImage. I've looked at the source code which is generated with this tool: https://github.com/rust-qt/ritual.
Is it possible to do this in regular Rust project without running complex multistage build involving code generation?
List of implemented slots for reference:
https://docs.rs/qt_widgets/0.3.0/x86_64-pc-windows-msvc/qt_widgets/
I've tried to copy paste generated code for other widgets and modify it, but it doesn't look like a right approach. I don't want to regenerate the whole library just for this case. Are there any simpler options?
When building the GRPC libraries from sources, for example on Android, I counter the following issues:
I have to remove libgrpc_unsecure and libgrpc++_unsecure in order
for the initialization of GRPC not to get stuck.
I see that there are two libraries: libprotobuf and libprotobuf-lite.
Which is the differences between them(other than the fact that
probably the lite version contains less functions), which one I
should include?
When generating the .so libraries it is generating also the .a
libraries and if I use the .a libraries a function is not found, so I
have to get back to using the .so, but in that case should I also use
the .a? If not, is there a way to build just the .so?
Is there a link where it specifies the purpose of each library and what should be used? For example I don't think grpc++_reflection is of some use in my case, but how do I know what it contains without having to pass through every symbol in it? I need to better understand how to use the library files.
Yes, libgrpc and libgrpc_unsecure are mutually exclusive. So you need to choose one as a dependency of your application.
Your interpretation is correct. lite version has less feature so you can try lite first and switch to the regular one if it doesn't fit. You may want to check this https://github.com/protocolbuffers/protobuf/blob/main/src/file_lists.cmake to see what's available and what isn't in the lite.
It depends on how you built gRPC.
gRPC has a couple of libraries but grpc++ is the one you want to link against. I don't think it has a comprehensive doc for what is for what so checking out https://github.com/grpc/grpc/blob/master/CMakeLists.txt is the best thing you can do to understand what features those libraries provide.
I would like to find out how I can import external libraries into my tests? For example, if i use a Java library for random name/number generation, how do I go about using it in my tests?
Thanks
Before I answer, I would advise that you should avoid using Java code, if you can. For example, a random name/number generator is very easy to implement in JavaScript and you can find plenty of ready-made examples out there. If it's JS code, you can easily embed it in your tests using one of the techniques described here. Even better, you should use capabilities that are provided out-of-the-box with OpenTest: $random and $randomString.
If you really need to use Java code, there are two ways to do it:
The recommended way: create one or more custom OpenTest keywords as described here. This will make it easier for you to maintain your test suite in the future and it also makes it easier for other members of your team to leverage this work in their own tests, especially if they are not familiar with Java.
The "quick and dirty" way: create a user-jars directory in your test actor's working directory and drop the JAR file in there. Then, call your Java code from JavaScript as described here.
I'm writing a single-page JavaScript application and I'm using Atom as my text-editor. (It's an Electron application, but that's besides the point.)
I'm also using the linter-jshint plugin for Atom. This is great, as it shows immediately in the text-editor when I make a typo in a variable, among other useful things.
Lately, my app has been getting very long. Naturally, I want to try and split it up across multiple files. After doing some research on StackOverflow, I've determined that I can use Grunt to automatically concatenate JavaScript files together. This is great because I don't have to refactor my code - I can just copy paste my existing functions into separate files. Easy!
However, once I do this, Atom fills up with warnings and errors from JSHint, because it can't find variables and functions that are located in the other files!
Now, I could just abandon the JHint plugin in Atom altogether and use the JSHint plugin for Grunt after the concatenation has already occured. But that sucks! I want the code that I'm going to be writing to be checked on the fly like a real IDE.
Is there a way to tell Atom/JSHint to assume that a bunch of JavaScript files will all be concatenated together? Or am I just approaching this problem completely wrong?
You can split your electron application with Node Common Modules, and use require('./state.js'); within your application.
Although I don't use Atom, that should allow for it to understand how you're using your variables and functions in other files.
Also this should eliminate your need for concatenation as the single-page app will have all it's dependencies accounted for.
Is it possible to use two generators on one project with yeoman?
For example: I want to use the angular-generator but also want to use another generator, whether it be custom or one of the bootstrap generators.
I know you can add dependencies through bower, but that doesn't add anything to my workflow(e.g. compiling less), does it?
Yes, it is not only possible, but common. Example: When you use JS-MV* generator in the project (generator-angular for instance) you will probably use generators responsible for other stuff, such as generator-travis-ci, generator-heroku.
Using two generators dedicated to two different JS-MV* frameworks ? NO. It makes no sense.
Yo can do it physically, for instance running generator-ember and generator-angular consequently in the same dir will result in angular's one trying to overwrite files generated previously by generator-ember.
As for the second question changing the workflow is basically changing the Gruntfile. It can be done by generators or by you, manually.
