How can I pass env vars to buster.js? - buster.js

I have a buster.js test. I need to pass some data to the test via an environment variable. How can I do this?

You mean when launching it at the command line?
I've just realized the question was made the '14, anyway:
Run any node.js application along with the variable assignment, e.g:
VARIABLE_NAME='FOO' buster-test file.js
In the code:
process.env.VARIABLE_NAME;

How to fetch the value of environment variable in Jenkins

I'm trying to inject an environment variable at build step Invoke Maven whose value was set at pre-build step through Execute Shell
#!/bin/bash
ipAddressHub=$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' selenium-hub)
echo $ipAddressHub
echo 'ipAddress=$ipAddressHub' > ipAddress.properties
Now I want to fetch the value of ipAddress stored in ipAddress.properties. I'm using Inject environment variables after Execute Shell and provide ipAddress.properties in Properties File Path field (not sure if that's the right way) and then i use build step Invoke Maven Artifactory and provide the command below.
clean install -DipAddress=${ipAddressHub} -Denv=${env} -Durl=${appURL} -DserverIP=${ipAddress}
But i don't get the value in serverIP, instead i get ${ipAddressHub} in console. I know i'm making some mistake, can anybody point out what's the correct way?
I hadn't used the plugin (at least not for a while), and I was going to suggest that you are just referencing it incorrectly?
I believe if you are adding it as an environment variable (and you can check it is adding by clicking on Environment Variables on the left side of the build screen).
You should be able to reference it like below?
${env.ipAddressHub}
This is untested though. Just going from memory.
Did some browsing and found an answer to it.
You can embed variables only in double-quoted strings. So the problem was
echo 'ipAddress=$ipAddressHub' > ipAddress.properties
changed it to
echo 'ipAddress='"$ipAddressHub"' > ipAddress.properties
And it worked like a charm

AWS Data Pipeline: setting local variable in shell command

I am trying to make use of the uuid library within a shell command invoked by an AWS data pipeline. It seems like the uuid function works fine, but when I try to pass this value to a variable, the data is lost.
A snippet of my testing script below:
sudo yum -y install uuid-devel
myExportId=$(uuid)
echo 'myExportId:' $myExportId
uuid
When I look at the activity log for the pipeline I see that the uuid function seems to be working, but the variable does not seem to contain anything?
myExportId:
b6cf791a-1d5e-11e6-a581-122c089c2e25
I notice this same behavior with other local variables in my scripts. Am I expressing these incorrectly?
My pipeline parameters are working fine within the script, so no issues there.
Shortly after posting this I realized that I had encoded some of the above steps in subshells within my pipeline definition. It can be difficult debugging shell scripts embedded within JSON, so I think I will move on to using the scriptUri parameter pointing to a bash file.

Accessing parameters passed in make command

My first day with makefile and gulp and here i need to pass couple of parameters in my make command from the terminal and use those params later on elsewhere.
Presently my make command would be "make xyz". Need it to be something like "make xyz --paramOne=abc" and use this "abc" elsewhere in the framework.
Completely at loss here! I have been using grunt and aware of how grunt works. Any help or leads would be of immense help.
Thanks!
Use environment variables.
paramOne=abc make xyz
You can access the inherited environment variables in your code. For example, in Node.js,
console.log(process.env.paramOne);
// => abc

Access build folder in Xcode Server CI bot run (env variables?)

I need to access the folder that is created dynamically during each bot integration. On one of the run it is something like this -
/Library/Developer/XcodeServer/Integrations/Caches/a3c682dd0c4d569a3bc84e58eab88a48/DerivedData/Build/Products/Debug-iphonesimulator/my.app
I would like to get to this folder in an post trigger, how do I go about it? Based on the wwdc talk it seems like some environment variables like 'XCS_INTEGRATION_RESULT' and XCS_ERROR_COUNT etc.. are being used. Also I can see in logs something like PROJECT_DIR.
But I can't access any of these variables from my command line(is it because I am a different user than the bot?)
Also where can I find the list of variables created by this CI system?
I have been echoing set to the bot log, the first line of my bot script is simply
set
When you view the log after the integration is complete it will be in your trigger output.

#Viktor is correct, these variables only exist during their respective sessions. #Pappy gave a great list of those variables.
They can be used in a script like so:
IPA_PATH="${XCS_OUTPUT_DIR}/${XCS_BOT_NAME}.ipa"
echo $IPA_PATH
I'm not familiar with Xcode Server but generally Unix/CI systems when export environment variables they only export it to the current session.
If you want to set an environment variable persistently you have to set it in an initializer file like ~/.bash_profile or ~/.bashrc so it always gets set/loaded when a shell session starts (ex: when you log in with Terminal - the exact file depends on what kind of shell you start).
It wouldn't make much sense to export these persistently either, because in that case if you run different integrations these would simply overwrite each others exported environment variables (they would set the same environment variables).
That's why the systems which communicate through environment variables usually don't write the variables into persistent initialiser file rather just export the variables. With export the variable is accessible from the process which exports it and from the child processes the process starts.
For example in a bash script if you export a variable you can access it from the bash script after the export and from any command/program you start from the bash script, but when the bash script finishes the environment won't be accessible anymore.
edit
Just to clarify it a bit: You should be able to access these environment variables from a post trigger script, run by Xcode Server but you most likely won't be able to access these from your Terminal/command line.
Also where can I find the list of variables created by this CI system?
You can print all the available environment variables with the env command. In a bash script simply type env in a new line like this:
#!/bin/bash
env
This will print all the available environment variables (not just the ones defined by Xcode Server!) - you can simply pipe it to a file for inspection if you want to, like this:
#!/bin/bash
env > $HOME/envinspect.txt
After this script runs you can simply open the envinspect.txt file in the user's home folder.

Pass variable from Jenkins to Ruby script (Jenkins newbie)

I've pulled a few scripts into Jenkins for a proof of concept and think I'd like to move that direction for all of our scripts. Right now I keep an environment.rb file with my code (watir-webdriver, cucumber) which tells the script which environment we're testing and which browser to use (global variables). Jenkins fires off the script using rake.
I'd love to let the user choose the environment and browser through Jenkins 'choice' variable or similar, and then pass that to the script. While I see the framework in that for Jenkins and set up a choice list for environment, I'm having trouble determining what the next step is.
I could write to environment.rb, I could pass a variable to rake - I have many options for how to pass the information, I just need some assistance finding the first step to find the Jenkins way of accomplishing them. Google results and previous Stack questions weren't what I was looking for.
Thanks
Sure. Give the user either a text entry field a dropdown after telling Jenkins that this is a parameterized build. You'll give them a name, something like BuildEnvironment. Then when you call the build, you can pass these from the environment variables. For example, if you were using ANT, you'd add a line to the parameters that said environment = ${MyEnvironment} Jenkins will then pass the value along for your build tool to use.
There is a way to pass Jenkins Environment Variable to Ruby script. Please see the following example:
workspace_path = `echo $WORKSPACE`.strip # note the use of backticks
puts workspace_path
In the "echo $WORKSPACE".strip # the code work only if you replace quotes with backticks
This code example works in Jenkins on a Linux system.
