I have a cross-platform desktop application written in Xamarin.Forms that runs both in Windows and MacOS. I want to do some UI automation on top of that application.
After some research it seems like the most cross-platform friendly option is to use Something like Sikuli. As the default stack on our team is centered on the .NET stack we want to use SikuliSharp or Sikuli4Net to perform the automated UI tests.
However, despite of the fact that we've been able to run Sikuli4Net successfully on Windows, automating several flows so far. We have a dire situation on MacOS. Our team (myself included) doesn't have a lot (or maybe any) knowledge of Java applications.
I've installed the JDK 8, but was unable to run the tests in the same way we did on Windows. The code builds, but it seems like something in the environment is lacking.
With Sikuli4Sharp when starting the APILauncher like this:
launch = new APILauncher(true);
launch.Start();
I get the following error:
With SikuliSharp when trying to run a simple demo application on our software I have this error:
I have tried to set up the SIKULI_HOME environment variable using this answer as a reference, but still the same problem (and I did restart the console and IDE, even my machine).
When I run echo $SIKULI_HOME on the terminal I do get the directory that cointains the .jar files:
So I'm kind of lost about were to go from here. These problems made me unsure about being possible to run Sikuli4Net or SikuliSharp on MacOS environments. Is this the case? If not, what am I doing wrong?
as mentioned in the error message: sikuli-script.jar is missing.
You have to check on what version of Sikuli/SikuliX your SikuliSharp or Sikuli4Net are depending on.
In doubt you have to dive into the sources of those Net packages.

I am using asp.net core 2.2 and Visual Studio 2019. The containers my application are running on are Debian (one of the official aspnet:2.2 docker images)
So my situation is this. I have an application that consists of 4 microservices running in docker containers and I'm seeing very high cpu usage on the containers nodes when this is under load. What I would like to do is profile the executing code to get an idea where this resource use is happening.
As a starting point I thought I would simply get some profiling running on my local development environment, just to get an idea of what the execution looks like in general. Although in production this runs in Kubernetes I do have a development environment that uses docker compose and I find the Visual Studio Docker tools to be fairly good.
I was hoping to use some of the visual studio profiling tools. I was able to install VSDBG on one of my locally running containers and connect to it with VS BUT in the diagnostic pane I see "the diagnostic tools window does not support the current debugging configuration". I've also tried just running the project from VS using docker compose but I see the same message when I hit a breakpoint. I'm not finding much out there about how to do this.
I also tried getting profiling going using perfcollect but after I generated the trace and opened it with perfviewer I was getting a parsing error when trying to view the cpu stacks . Still not sure what's going on there. I did find an old closed issue on their github describing what I am seeing but there was a fairly recent comment from someone saying they were seeing it with the latest version so maybe it's a regression.
So.. after all this .. my question is this. Are either of the above approaches viable? Is there a better way to achieve this? I'm interested in any way someone has had success viewing some code profiling of a .net core 2.2 application running on a linux docker container. All I really want to do is be able to see where in my code the execution time is going and what resources are being consumed. As I've mentioned I'm not finding much out there when I Google for this and I seem to keep hitting walls. If anyone had any advice or direction on a approach here I would really appreciate it. Thanks much!
Are you open to upgrading to .Net Core 3.0 (.Net Core 2.2 is going out of support in a few days: 12/23/2019)
If you're open to that you can take advantage of the new tool dotnet-trace which supports running in a linux container and can be used with the tools in Visual Studio.
Here are the steps I used to add it to my project:
Change your base image to use the sdk image (needed to install the tool).
Add installing the tool to the image:
RUN dotnet tool install --global dotnet-trace
ENV PATH $PATH:/root/.dotnet/tools
Alternatively if you don’t want to add it in your image you can run the following commands in a running container (as long as it as based on the SDK image):
dotnet tool install --global dotnet-trace
export PATH="$PATH:/root/.dotnet/tools"
Start the project without debugging (Ctrl+F5)
Use the Containers Tool Window to open a terminal window
Run the command:
dotnet-trace collect --process-id $(pidof dotnet) --providers Microsoft-DotNETCore-SampleProfiler
When you are done collecting press enter or Ctrl+C to end the collection
This will crate a file called “trace.nettrace”
By default that /app folder that file would be created in is volume mapped to your project folder. You can open the file from there in VS.
I am trying to build and deploy a gaia build from git repo in Windows. I am trying to deploy it in অ Flame.
I am trying to do it in a windows 7 with cygwin installed. After installing everything this is the error I am getting
This works just fine in a Linux machine, but I need to do this in Windows since right now I have access to it only.
Any pointers to what I am doing wrong here?
I'm afraid it's not going to work without significant effort for several reasons. Much better to use a VM with Linux on as even if it did work it will be really slow. Windows is slow at handling lots of file access and Cygwin slows it down even more.
For example in making a simple change to config.sh (full stack build) so it works on Cygwin I found it took hours to run (on a decent PC). And then I had a couple of corrupt git repos I had to hand fix.
I also looked at getting gaia's make to work, but stopped after the problem just got bigger.
Here's what I found for future reference
The build is not really portable, it expects a linux like environment
While cygwin gives good linux emulation most of the tools run are win32 native and handling path conversion for them requires not trivial changes due to assumptions. For example you can switch to the Win32 XPCshell and hack the command line paths to use cygpath, but environment variable are an extra source of dependency in the JS scripts and are all unix paths. ( I did manage this part).
these path and environment dependencies get magnified with the C build chain and other tools.
You need to change the mount to use noacl or else cygwin attaches ACLs to simulate file properties, thus breaking things. It's might even be a little faster without ACLS
I also tried MinGW which provides native versions without the emulation so should be faster. However it falls short of the requirements and its automatic path conversion heuristics get in the way.
you need to turn of any antivirus prog as they slow it down. in fact the very first time I used the old FIrefox WIndows build it would crash after a long time. Turned out to be a mem leak in the AV :(
So all-in-all it's too much hassle in terms of dev time to convert and probably maintain. A true Windows build would be better but then it's so easy these days to run a VM. You can even share directories between the guest and host so could flash from Windows.
I also tried with cygwin, but was unable to build the gaia source code on windows.
It's not straightforward to build the gaia source code on windows. Please follow these steps:-
Download Mozilla Build from MozillaBuild - Mozilla Wiki and install the tools in c:/mozilla-build (preferred). It includes everything (make, wget, python etc) you need to build gaia source code.
Run start-shell.bat. If build process failed with this batch file then run start-shell-msvc2013.bat if you have Visual Studio 2013 or start-shell-msvc2015.bat if you have Visual Studio 2015. (You need Visual Studio for the second step).
Browse to the gaia source code directory using the command cd Mozilla/gaia.
Run DEVICE_DEBUG=1 make command. Don't run DEVICE=1 make or make command (because you won't be able to debug the apps, I was able to connect to the Firefox OS 2.2 but was not able to debug the apps when I ran these commands).
If you are running this command for the first time, it will download the b2g_sdk otherwise it will create a folder profile with your custom profile.
Open the WEBIDE using Firefox (Nightly preferred) and point to the profile folder you just created.

I'm starting to work with ZeroBrane for Corona SDK Starter license development under Linux using Wine. The problem is that i cannot make it work the debugger by adding breakpoints over different sections of the code.
The Corona Simulator path on the user.lua configuration is defined and opens the Simulator successfully, but the game is not paused by the breakpoints.
I also added the following line at the beggining of my main.lua file
require("mobdebug").start()
There is some way to make it work the debug session in Linux?
Note: Someone with the enough reputation, can create the zerobrane tag?
Breakpoints not working is usually caused by different paths reported by the Lua engine (in this case embedded in Corona SDK) and the IDE itself. You can see what path is being reported by your engine if you include something like this in your script: print(debug.getinfo(1,"S").source)
If you are running ZeroBrane Studio using Wine as well, you may want to try running it under Linux (while still running Corona SDK using Wine). ZBS will attempt to do partial matching between your project paths under Wine and Linux, which may work better in this particular case.
If this doesn't resolve the issue, feel free to send a message to ZeroBrane Studio maillist and I can provide additional details on how to troubleshoot this further.
I made a minor change to a legacy Visual C++ / MFC app built with VS 2008. I changed some UI resources in the .rc file and compiled without any problems, then deployed it on my client's system. However, the program which was previously doing fine now fails to run on exactly one of their servers. It works fine on my laptop and on their other servers, many of whom are basically identical to the one having the trouble.
The weird thing however is that there is absolutely no error message whatsoever. No message box, no errorlevel set (when run on command prompt), no Dr. Watson entry, no nothing.
It's an MFC app that does not really comprise anything very special. It does link in some external libraries – e.g., some old version of the Xerces C++ XML parser. But this is probably not too relevant, right?
The program has a class derived from CWinApp, and I tried to add some logging in its constructor. Based on this, it looks like not even this constructor is reached.
The server in question is running Windows Server 2003 Standard Edition Service Pack 2, and we are trying to run the program in a Remote Desktop session. (Because of the client's environment, I cannot easily test in a console session right now.)
I reverted my changes from version control, which did not help – but I do not know if I had built myself the previously installed version (which ran just fine even on this server) or if it had been built by someone else.
Have also tried to reinstall the Visual C++ runtime libraries and of course reboot Windows, but neither helped. Now I'm really running out of ideas... Any clues on what I could try or check?
Probably some error occurs but is surpressed e.g. empty catch() statement or similar.
You could try and install Debugging tools for Windows WinDbg to see if you could get more info when trying to run it. Since the download is rather small 25Mb maybe it is possible to install it on your client's PC.
But first check the eventview log for your app, maybe there is something in there that can shed some light.
I have an Erlang application that is deployed on a server with Windows Server 2008.
The way I do this:
Copy application folder in Erlang lib directory.
Open command line (cmd). Execute erl.
Execute application:start(app_name) in Erlang shell.
Are there any better approaches to launch the application? How to make the application to launch on Windows startup?
I have no experience with Windows but...
`1. First of all, you might want to have a look to the concept of release in Erlang. Essentially,
When we have written one or more applications, we might want to create a complete system consisting of these applications and a subset of the Erlang/OTP applications. This is called a release.
`2. Then, you might want to create a script that contains something like:
erl -boot ch_rel-1
Where essentially you're starting Erlang/OTP using a boot script that you created above (just follow the instructions in the releases page)
`3. This article explains how to create startup scripts in Windows Server 2008 (not tested, just googled):
http://technet.microsoft.com/en-us/magazine/dd630947.aspx
Hope this helps. Nice question.
Perhaps rebar might help. It makes building an app skeleton and release quite easy. A nice tutorial is here.
After getting familiar with releases, take a look at manual pages (erl -man ) for start_erl and erlsrv. I used them to start embedded system ( http://www.erlang.org/doc/embedded/embedded_nt.html ) in windows 2003, hope it still works for you in windows 2008.
After creating service with erlsrv it is possible to manage it via standard windows command line and GUI tools, e.g. setting start mode and restart policy.
May be you could start just your application by supplying "-s app_name" as erl/start_erl additional flag, but I didn't try that, as I had to go long route with embedded system release. In that case make sure you have "start() -> application:start(?MODULE)." in your "app_name.erl".
