I am on PDI 7.0 and have a "Modified Java Script Value" step inside a transformation as below:
var numberOfDays = 100;
Alert(numberOfDays);
setVariable("NUMBER_OF_DAYS", numberOfDays, "r");
Alert(getVariable("NUMBER_OF_DAYS", ""));
However, when I run the transformation, the first Alert correctly throws 100, but the next Alert is blank (meaning the variable is not set).
What is wrong here?
As a rule of thumb, you should never set a variable and read it within the same transformation.
See a warning that pops up in Spoon when setting up Set Variables step:
That said, what you could do, if you really insist on setting this via Java Script is the following design:
where
1) Set variable transformation is used to set the value:
var numberOfDays = 100;
Alert(numberOfDays);
setVariable("NUMBER_OF_DAYS", numberOfDays, "r");
2) Get variable transformatoin only reads it
Alert(getVariable("NUMBER_OF_DAYS", ""));
Both transformations use the same steps, but they have separate task.

When we use karate.fork for CLI command and need some information from there to be stored in a variable and using it in the next step.
for EX - karate.fork('java -version')
We need to get only the version data alone.
Then karate.fork() is the wrong choice - just use karate.exec() instead. It does the same thing, but will block, and also return the console output:
* def output = karate.exec('java -version')

JMeter OS Process Sampler is set up, works fine and saves result (a token as result of powershell srcipt execution) to a file.
Is it possible somehow to save result from powershell script directly into a JMeter variable instead?
What should I add for that?
Normally you should be using JMeter Post-Processors in order to extract data from Sampler's responses
If the token is the only thing that your powershell script returns you can extract it using i.e. Boundary Extractor, just provide desired variable name and leave everything else empty
Demo:
If there is some other text surrounding the token - adjust the boundaries accordingly or go for Regular Expression Extractor
I am new to SSIS . I am trying to use Script Task to get the last modified date and create date of a file. I have declared two variables to read the file path and file name (File_Path,Filename) in my script task as variables with scope as package and datatype as string.
I want to store the create date and modified date to two diff output variables(Create_Date,Last_Updated) with datatype as Datetime.
my code for the script is as follows
FileInfo fileInfo = new FileInfo(Path.Combine(Dts.Variables["File_Path"].Value.ToString(), Dts.Variables["Filename"].Value.ToString()));
if (fileInfo.Exists)
{
// Get file creation date
Dts.Variables["Create_Date"].Value = fileInfo.CreationTime;
// Get last modified date
Dts.Variables["Last_Updated"].Value = fileInfo.LastWriteTime;
}
else
{
Dts.Events.FireWarning(1, Dts.Variables["System::TaskName"].Value.ToString()
, string.Format("File '{0}' does not exist", fileInfo.FullName)
, "", 0);
}```
SSIS has a Design time and a Run time interface.
Variables are created in the Design time space. There you assign data type and a value. There is an explicit Variable's window that you do all of this with.
During run time, the Variables window will still be visible but the values there are not the run-time value. It's just a reference for what the package was initialized with. The actual values of SSIS variables are to be found in the debug windows. I favor the Locals window (Ctrl+Alt+V, L)
From there, expand the Variables node
You can also add explicit logging into your Script tasks. This little bit will enumerate through all the variables you selected for readonly or read/write access and pop off their name and value into the run log. If you're running in Visual Studio, it will show up in the Results tab or the Output window (great place to copy errors for further research or asking on forums). If you're running from the server, these will show in the SSISDB.catalog.operation_messages view (unless you picked an incompatible logging mode)
bool fireAgain = false;
string message = "{0}::{1} : {2}";
foreach (var item in Dts.Variables)
{
Dts.Events.FireInformation(0, "SCR Echo Back", string.Format(message, item.Namespace, item.Name, item.Value), string.Empty, 0, ref fireAgain);
}
I have a basic function in BeanShellSampler.bshrc at Jmeter 4.0
String getMyString(String strParam) {
return "MyString: "+strParam;
}
I called in BeanShell Sampler as below
String N = "123123";
log.info("${__BeanShell(getMyString("${__V(Var${N})}"),)}");
When I run Sampler output is somthing like that.
2018-06-18 15:25:40,080 INFO o.a.j.u.BeanShellTestElement: MyString: Var${N}
How can I set string variable to my function?
I read function articles in Jmeter web site
Thank you.
Add the next line to user.properties file:
beanshell.sampler.init=BeanShellSampler.bshrc
Amend your code to look like:
String N = "123123";
log.info(getMyString(N));
That's it, you should get MyString: 123123 in jmeter.log file
Be aware that starting from Jmeter 3.1 it is recommended to use Groovy for all forms of scripting as Groovy performance is much better comparing to Beanshell so consider taking the following steps instead:
Create a file, i.e. foo.groovy in "bin" folder of your JMeter installation and put your function there:
String getMyString(String strParam) {
return "MyString: " + strParam;
}
Add the next line to user.properties file:
You should be able to refer your custom code from __groovy() function like:
${__groovy(log.info(getMyString("123123")),)}
functions can be used anywhere in the Test Plan
For each BeanShell Program type there are different beanshell.*.init properties defined in bin/user.properties
beanshell.function.init=BeanShellFunction.bshrc
beanshell.preprocessor.init=BeanShellSampler.bshrc
beanshell.postprocessor.init=BeanShellSampler.bshrc
beanshell.assertion.init=BeanShellFunction.bshrc
Hence the same function which needs to be called from any program(preprocessor, postprocessor, etc) we need to copy the function to every .bshrc file OR use same .bshrc file for every program init property.
In your case if you are using local string variable N and passing it along with the script. If you use ${Variable} there must be a JMeter variable defined so that JMeter can pick its value. To do that you can use vars.put , write N value to JMeter variables and use ${N} .
I have defined Var123123 value as FinalValue as shown below
And 2 beanshell samplers one is to put String variable N to Jmeter variable and one is beanshell script as shown below
You can see in the log its printed VAR123123's value which is FinalValue
The reason why i took 2 beashell samplers is if i write N to JMeter variables and use it in same script its not updating N value until the sampler executed..

My group does a lot of test automation with JM. Typically we have a properties file which has a bunch of variables defined. These in turn are mapped to "User Defined Variables" of which we have a number of different sets.
These are in referenced throughout the rest of the jmx - I find it difficult as there are so many variables in so many different places to know what is what. Is there any way to have jmeter display what values its variables have - custom sampler is fine ? Ideally id love it if you could just hover a var and have its value displayed.
Any ideas ?
The newest versions of Jmeter have a fantastic sampler called "Debug Sampler" that will show you the values for: Jmeter Variables, Jmeter Properties or System properties.
You can insert them wherever you want in the script to get values at a given time. You'll want to have a "View Results Tree" enabled to view the sampler.
Given that Jmeter declares variables from a file on run, you won't be able to get your ideal solution.
I'm curious...would it be cleaner to employ "CSV Data Set Config" rather then populating "User Defined Variables" from a properties file?
Edit: Added explanation on variable declaration and asked CSV question.
Here is how I used to get Set of vars right through the code (variant with Java code in JSR223 PostProcessor):
Add "JSR223 PostProcessor" by right click wherever you need to check jMeter variables in your project;
Set Language (in my case - to java);
Add following code to Script window:
import java.util.Map;
String jMeterVars;
jMeterVars = "Quantity of variables: " + vars.entrySet().size() + ".\n\n";
jMeterVars += "[VARIABLE NAME] ==>> [VARIABLE VALUE]\n\n";
for (Map.Entry entry : vars.entrySet()) {
jMeterVars += entry.getKey() + " ==>> " + entry.getValue().toString() + "\n";
}
try {
FileWriter fw = new FileWriter("D:\\jMeterVarsForStackOverflow.txt",true);
fw.write(jMeterVars);
fw.close();
} catch(IOException ioe) {
System.err.println("IOException: " + ioe.getMessage());
}
Check that everything in the JSR223 PostProcessor looks like that:
Start your project in jMeter.
The code above will create jMeterVarsForStackOverflow.txt file at D: and put all variables there:
