How to execute bash script using karate and fail if script fails

I'm trying to execute bash script using karate. I'm able to execute the script from karate-config.js and also from .feature file. I'm also able to pass the arguments to the script.
The problem is, that if the script fails (exits with something else than 0) the test execution continues and finishes as succesfull.
I found out that when the script echo-es something then i can access it as a result of the script so I could possibly echo the exit value and do assertion on it (in some re-usable feature), but this seems like a workaround rather than a valid clean solution. Is there some clean way of accessing the exit code without echo-ing it? Am I missing on something?
script
#!/bin/bash
#possible solution
#echo 3
exit 3;
karate-config.js
var result = karate.exec('script.sh arg1')
feture file
def result = karate.exec('script.sh arg1')

Great timing. We very recently did some work for CLI testing which I am sure you can use effectively. Here is a thread on Twitter: https://twitter.com/maxandersen/status/1276431309276151814
And we have just released version 0.9.6.RC4 and new we have a new karate.fork() option that returns an instance of Command on which you can call exitCode
Here's an example:
* def proc = karate.fork('script.sh arg1')
* proc.waitSync()
* match proc.exitCode == 0
You can get more ideas here: https://github.com/intuit/karate/issues/1191#issuecomment-650087023
Note that the argument to karate.fork() can take multiple forms. If you are using karate.exec() (which will block until the process completes) the same arguments work.
string - full command line as seen above
string array - e.g. ['script.sh', 'arg1']
json where the keys can be
line - string (OR)
args - string array
env - optional environment properties (as JSON)
redirectErrorStream - boolean, true by default which means Sys.err appears in Sys.out
workingDir - working directory
useShell - default false, auto-prepend cmd /c or sh -c depending on OS
And since karate.fork() is async, you need to call waitSync() if needed as in the example above.
Do provide feedback and we can tweak further if needed.
EDIT: here's a very advanced example that shows how to listen to the process output / log, collect the log, and conditionally exit: fork-listener.feature
Another answer which can be a useful reference: Conditional match based on OS
And here's how to use cURL for advanced HTTP tests ! https://stackoverflow.com/a/73230200/143475
In case you need to do a lot of local file manipulation, you can use the karate.toJavaFile() utility so you can convert a relative path or a "prefixed" path to an absolute path.
* def file = karate.toJavaFile('classpath:some/file.txt')
* def path = file.getPath()

How to execute selenium script/batch using java

Would like to execute selenium script/batch scripts using java. Based on input parameters to call script/batch scripts.
To understand, how to run script/batch using java code.
Please help me out here.

to run a bash script contained in a file in a java project, use the ProcessBuilder class like this:
ProcessBuilder procBuildScript = new ProcessBuilder ([your_script_path],arg1,arg2,...);
procBuildScript.start();
So you can pass arguments after your script path
as "script.sh",arg1,arg2
For example :
public void runMyScript(String aFirstArg, String aSecondArg){
ProcessBuilder procBuildScript = new ProcessBuilder("./your-script.sh",aFirstArg,aSecondArg);
procBuildScript.start();
}
In your script you can call these arguments using the expressions $ 1, $ 2 ... $ {10}, $ {11} corresponding to the index where the desired parameter is located :
#!/bin/bash
# your-script.sh
echo "First argument is : $1"
echo "Third argument is : $3"

how to use windows default voice using java? [duplicate]

Is there a way to use the MS Speech utility from command line? I can do it on a mac, but can't find any reference to it on Windows XP.

My 2 cents on the topic, command line one-liners:
on Win using PowerShell.exe
PowerShell -Command "Add-Type –AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).Speak('hello');"
on Win using mshta.exe
mshta vbscript:Execute("CreateObject(""SAPI.SpVoice"").Speak(""Hello"")(window.close)")
on OSX using say
say "hello"
Ubuntu Desktop (>=2015) using native spd-say
spd-say "hello"
on any other Linux

commandline function using google TTS (wget to mp3->mplayer)
command using google with mplayer directly:
/usr/bin/mplayer -ao alsa -really-quiet -noconsolecontrols "http://translate.google.com/translate_tts?ie=UTF-8&client=tw-ob&q=Hello%20World&tl=en";
on Raspberry Pi, Win, OSX (or any remote) using Node-Red
npm i node-red-contrib-sysmessage

There's a nice open source program that does what you're asking for on Windows called Peter's Text to Speech available here: http://jampal.sourceforge.net/ptts.html
It contains a binary called ptts.exe that will speak text from standard input, so you can run it like this:
echo hello there | ptts.exe
Alternatively, you could use the following three line VBS script to get similar basic TTS:
'say.vbs
set s = CreateObject("SAPI.SpVoice")
s.Speak Wscript.Arguments(0), 3
s.WaitUntilDone(1000)
And you could invoke that from the command line like this:
cscript say.vbs "hello there"
If you go the script route, you'll probably want to find some more extensive code examples with a variable timeout and error handling.
Hope it helps.

There's also Balabolka: http://www.cross-plus-a.com/bconsole.htm
It has a command line tool balcon.exe. You can use it like this:
List voices:
balcon.exe -l
Speak file:
balcon.exe -n "IVONA 2 Jennifer" -f file.txt
Speak from the command-line:
balcon.exe -n "IVONA 2 Jennifer" -t "hello there"
More command line options are available. I tried it on Ubuntu with SAPI5 installed in Wine. It works just fine.

If you can't find a command you can always wrap the System.Speech.Synthesis.SpeechSynthesizer from .Net 3.0 (Don't forget to reference "System.Speech")
using System.Speech.Synthesis;
namespace Talk
{
class Program
{
static void Main(string[] args)
{
using (var ss = new SpeechSynthesizer())
foreach (var toSay in args)
ss.Speak(toSay);
}
}
}

There is a powershell way also:
Create a file called speak.ps1
param([string]$inputText)
Add-Type –AssemblyName System.Speech
$synth = New-Object System.Speech.Synthesis.SpeechSynthesizer
$synth.Speak($inputText);
Then you can call it
.\speak.ps1 "I'm sorry Dave, I'm afraid I can't do that"

rem The user decides what to convert here
:input
cls
echo Type in what you want the computer to say and then press the enter key.
echo.
set /p text=
rem Making the temp file
:num
set num=%random%
if exist temp%num%.vbs goto num
echo ' > "temp%num%.vbs"
echo set speech = Wscript.CreateObject("SAPI.spVoice") >> "temp%num%.vbs"
echo speech.speak "%text%" >> "temp%num%.vbs"
start temp%num%.vbs
pause
del temp%num%.vbs
goto input
pause

Your best approach is to write a small command line utility that will do it for you. It would not be a lot of work - just read text in and then use the ms tts library.
Another alternative is to use Cepstral. It comes with a nice command line utility and sounds light years better than the ms tts.

execute commands of another program from a tidesdk program

I'm testing tidesdk.
I have a java program that reads from standard input.
I run the program through the console console
java -cp MyProgram.jar package.MyMainClass
And then execute commands and get results.
there any way to do with tidesdk?
Edit:
The problem was that calls the java program with a list of one element (which contained the command separated by spaces)
It solved with passing every word to a item of list (and removing the spaces).
Right now I have porblemas to write standard input. This is what I'm trying.
var input = Ti.Process.createPipe();
var process = Ti.Process.createProcess({
args:['java', '-cp', 'C:/.../MyProgram.jar', 'package.MyMainClass'],
stdin: input
});
//process.setOnReadLine(function(line) { alert(line) });
process.launch();
input.write("comand parameter1 parameter2\n"); //This line does not work
The java program starts. But never gets a command.

Checkout Documentation of Ti.Process.createProcess. That is exactly what you are looking for:
http://tidesdk.multipart.net/docs/user-dev/generated/#!/api/Ti.Process

Different output -- when running mathtext in command line and when the command is executed from a java program using apache-commons-exec

I am trying to run mathtext from a java program using apache-commons-exec. The problem is I am getting different output when I run the same command from a java program and when I run it through shell.
so if run mathtext like this in the shell:
./mathtext test.png "\$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}\$"
in a shell I get the perfect png
but when I run the same thing using apache-commons-exec
Map map = new HashMap();
map.put("target", new File(trgtFileName));
DefaultExecuteResultHandler resultHandler = new DefaultExecuteResultHandler();
Executor exec = new DefaultExecutor();
exec.setWorkingDirectory(/*I set the working directory where the mathtext is*/);
CommandLine cl = new CommandLine("./mathtext");
cl.addArgument("${target}");
cl.addArgument(latex);
cl.setSubstitutionMap(map);
// Logger.log4j.info("command is:::"+cl.toString());
ExecuteWatchdog watchdog = new ExecuteWatchdog(5000);
exec.setWatchdog(watchdog);
exec.execute(cl,EnvironmentUtils.getProcEnvironment(),resultHandler);
resultHandler.waitFor();
I get the image, not the equation but the raw TeX string :(
Can somebody please help me in solving the issue? I want to get the exact output.
Thanks.

I figured out where the problem was:
$ is a special character for the unix shell and not for java. So even if in the command line the input needs to escape $ like:
"\$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}\$"
inside the java program I dont need to escape the '$' or put " (double quotes) at the beginning and at the end.I had to put the command like:
$\frac{{\left( {{p^2} - {q^2}} \right)}}{2}$
Hope this helps somebody :)
