Noob to Gatling/Scala here.
This might be a bit of a silly question but I haven't been able to find an example of what I am trying to do.
I want to pass in things such as the baseURL, username and passwords for some of my calls. This would change from env to env, so I want to be able to change these values between the envs but still have the same tests in each.
I know we can feed in values but it appears that more for iterating over datasets and not so much for passing in the config values like I have.
Ideally I would like to house this information in a JSON file and not pass it in on the command line, but maybe thats not doable?
Any guidance on this would be awesome.
I have a similar setup and you can use pure scala here .In this scenario you can create an object called Config for eg
object Configuration { var INPUT_PROFILE_FILE_NAME = ""; }
This class can also read a file , I have the below code in the above object
val file = getClass.getResource("data/config.properties").getFile()
val prop = new Properties()
prop.load(new FileInputStream(file));
INPUT_PROFILE_FILE_NAME = prop.getProperty("inputProfileFileName")
Now you can import this object in Gattling Simulation File
val profileName= Configuration.INPUT_PROFILE_FILE_NAME ;

I am currently writing tests for a function that takes file paths and loads a dataset from them. I am not able to change the function. To test it currently I am creating files for each run of the test function. I am worried that simply making files and then deleting them is a bad practice. Is there a better way to create temporary test files in Scala?
import java.io.{File, PrintWriter}
val testFile = new File("src/main/resources/temp.txt" )
val pw = new PrintWriter(testFile)
val testLines = List("this is a text line", "this is the next text line")
testLines.foreach(pw.write)
pw.close
// test logic here
testFile.delete()
I would generally prefer java.nio over java.io. You can create a temporary file like so:
import java.nio.Files
Files.createTempFile()
You can delete it using Files.delete. To ensure that the file is deleted even in the case of an error, you should put the delete call into a finally block.
I have a Secret text binding Variable SECRET_TKN in jenkins job configuration. I want to access this var in .scala file . How do I access this var generically in my code?
I have tried the following but it doesn't seem to work correctly:
val token =sys.env("${SECRET_TKN}")
println ("value = " +token)
Console output shows value as SOME(***) thus causing the api calls to fail as I believe the keyword SOME is coming along with the actual fetched value.
Also, tried sys.env("${?STG_SERVICE_TKN}") but no luck.
sys.env is keyed by variable name, so this should work:
val token = sys.env("SECRET_TKN")
For your case, it would work if the SECRET_TKN is a variable being populated, it would work fine:
val SECRET_TKN = "SECRET_TKN"
val token =sys.env(s"${SECRET_TKN}")
It's better practice to use sys.env.get("mySecret") which will give you an Option[String] rather than throw an error if that variable is missing.
I'm surprised to not find a previous question about this, but I did give an honest try before posting.
I've created a ui with Qt Creator which contains quite a few QtWidgets of type QLineEdit, QTextEdit, and QCheckbox. I've used pyuic5 to convert to a .py file for use in a small python app. I've successfully got the form connected and working, but this is my first time using python with forms.
I'm searching to see if there is a built-in function or object that would allow me to pull the ObjectNames and Values of all widgets contained within the GUI form and store them in a dictionary with associated keys:values, because I need to send off the information for post-processing.
I guess something like this would work manually:
...
dict = []
dict['checkboxName1'] = self.checkboxName1.isChecked()
dict['checkboxName2'] = self.checkboxName2.isChecked()
dict['checkboxName3'] = self.checkboxName3.isChecked()
dict['checkboxName4'] = self.checkboxName4.isChecked()
dict['lineEditName1'] = self.lineEditName1.text()
... and on and on
But is there a way to grab all the objects and loop through them, even if each different type (i.e. checkboxes, lineedits, etc) needs to be done separately?
I hope I've explained that clearly.
Thank you.
Finally got it working. Couldn't find a python specific example anywhere, so through trial and error this worked perfectly. I'm including the entire working code of a .py file that can generate a list of all QCheckBox objectNames on a properly referenced form.
I named my form main_form.ui from within Qt Creator. I then converted it into a .py file with pyuic5
pyuic5 main_form.ui -o main_form.py
This is the contents of a sandbox.py file:
from PyQt5 import QtCore, QtGui, QtWidgets
import sys
import main_form
# the name of my Qt Creator .ui form converted to main_form.py with pyuic5
# pyuic5 original_form_name_in_creator.ui -o main_form.py
class MainApp(QtWidgets.QMainWindow, main_form.Ui_MainWindow):
def __init__(self):
super(self.__class__, self).__init__()
self.setupUi(self)
# Push button object on main_form named btn_test
self.btn_test.clicked.connect(self.runTest)
def runTest(self):
# I believe this creates a List of all QCheckBox objects on entire UI page
c = self.findChildren(QtWidgets.QCheckBox)
# This is just to show how to access objectName property as an example
for box in c:
print(box.objectName())
def main():
app = QtWidgets.QApplication(sys.argv) # A new instance of QApplication
form = MainApp() # We set the form to be our ExampleApp (design)
form.show() # Show the form
app.exec_() # and execute the app
if __name__ == '__main__': # if we're running file directly and not importing it
main() # run the main function
See QObject::findChildren()
In C++ the template argument would allow one to specify which type of widget to retrieve, e.g. to just retrieve the QLineEdit objects, but I don't know if or how that is mapped into Python.
Might need to retrieve all types and then switch handling while iterating over the resulting list.
I am working on a spark application. While writing test cases for application , i came across requirement where i need to initialize a var in object with different file rather than production file. For ex:
ObjA{
val properties: Properties = new Properties()
properties.load(new FileInputStream("constants.properties"))
val map = JavaConverters.propertiesAsScalaMapConverter(properties).asScala
}
In Test enviornment i wanted to use a different file other than constants.properties . i.e i wanted to initialize objA with file constant.properties present in test directory. I dont want to pass file name as argument to method. Is there a way where application figures out env(Test or production) and initialize variable as per that?
Thanks
You could use ip from driver (node you submit application). Before, initializing sparkContext finding you test env ip, you could do some thing like below,
import java.net._
val ip = InetAddress.getLocalHost
val props = if (ip == "ip-xx-xxx-xx-xx.ec2.internal") "TestConstant.properties" else "productionConstants.properties"
properties.load(new FileInputStream("props"))
so, in test env it is gonna load test property in any other env it is gonna load prod property
I am a Scala/PlayFramework noob here, so please be easy on me :).
I am trying to create an action (serving a GET request) so that when I enter the url in the browser, the browser should download the file. So far I have this:
def sepaCreditXml() = Action {
val data: SepaCreditTransfer = invoiceService.sepaCredit()
val content: HtmlFormat.Appendable = views.html.sepacredittransfer(data)
Ok(content)
}
What it does is basically show the XML in the browser (whereas I actually want it to download the file). Also, I have two problems with it:
I am not sure if using Play's templating "views.html..." is the best idea to create an XML template. Is it good/simple enough or should I use a different solution for this?
I have found Ok.sendFile in the Play's documentation. But it needs a java.io.File. I don't know how to create a File from HtmlFormat.Appendable. I would prefer to create a file in-memory, i.e. no new File("/tmp/temporary.xml").
EDIT: Here SepaCreditTransfer is a case class holding some data. Nothing special.
I think it's quite normal for browsers to visualize XML instead of downloading it. Have you tried to use the application/force-download content type header, like this?
def sepaCreditXml() = Action {
val data: SepaCreditTransfer = invoiceService.sepaCredit()
val content: HtmlFormat.Appendable = views.html.sepacredittransfer(data)
Ok(content).withHeaders("Content-Type" -> "application/force-download")
}
