I am trying to take a screenshot at different times of the automated test case.
In order to be able to save them where I want and have every screenshot with a unique name, I created a custom keyword as follows:
package multipleScreenshot
public class naming {
@Keyword
public void screenshotNaming(String path, String name){
String completePath = path + name + (int)(Math.random() * 10000)+ ".jpg"
println WebUI.takeScreenshot(completePath);
}
}
I have added the global variables name and path to the default profile:
I am calling the function in the test case as follows:
CustomKeywords.'multipleScreenshot.naming.screenshotNaming'(GlobalVariable.path, GlobalVariable.name)
Unfortunately I keep getting the same error no matter what I have tried. I would really appreciate some help.

Thank you very much, I’ve noticed that too after a while. Somehow it was automatically added.
Any idea how to use a time stamp instead of the random number to name the screenshot?
Keyword:
package my
import java.nio.file.Path
import java.nio.file.Paths
import java.time.LocalDateTime
import java.time.ZoneOffset
import java.time.format.DateTimeFormatter
import com.kms.katalon.core.annotation.Keyword
public class NamingUtils {
// My Time Zone
// See https://docs.oracle.com/javase/8/docs/api/java/time/ZoneOffset.html
// Choose appropriate ZoneOffset for you.
private static ZoneOffset myZoneOffset = ZoneOffset.of("+0900")
// My Date Time Formatter
private static DateTimeFormatter dtFormatter = DateTimeFormatter.ofPattern("yyyyMMdd-hhmmss")
@Keyword
public static String makeScreenshotPath(Path baseDir, String name){
// date time of now
LocalDateTime now = LocalDateTime.now(myZoneOffset)
String dateTime = dtFormatter.format(now)
Path p = baseDir.resolve(name + "_" + dateTime + ".png")
return p.toString()
}
}
Sample Test Case which uses my.NamingUtils.makeScreenshotPath Keyword:
import java.nio.file.Files
import java.nio.file.Path
import java.nio.file.Paths
import com.kms.katalon.core.configuration.RunConfiguration
import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI
Path projectDir = Paths.get(RunConfiguration.getProjectDir())
Path baseDir = projectDir.resolve("tmp")
Files.createDirectories(baseDir)
String screenshotPath = CustomKeywords."my.NamingUtils.makeScreenshotPath"(baseDir, "home")
WebUI.comment("screenshotPath=${screenshotPath}")
WebUI.openBrowser("http://demoaut.katalon.com")
WebUI.takeScreenshot(screenshotPath)
WebUI.closeBrowser()
When I ran the testcase, it created a PNG file of
<projectDir>/tmp/home_20200523-065803.png.
My “Materials” library provides more sophisticated solution for locating screenshot files.
Though Materials library could be too much for simple test cases.
Thank you very much. I am pretty new to Katalon Studio and Groovy so I still have to learn a lot. But I am determined to understand better.
I have tried to use your method but I keep getting this error
No signature of method: my.NamingUtils.makeScreenshotPath() is applicable for argument types: (java.lang.String) values: [C:\Users\Oana\Katalon Studio\Bachelor Thesis\tmp\home_20200523-074820.png]
Possible solutions: makeScreenshotPath(java.nio.file.Path, java.lang.String)
You are not careful enough about the type of argument passed to the keyword: not java.lang.String, but java.nio.file.Path. Read the sample code thoroughly.
Possibly you should set back yourself and learn Java 8 programming with some good books before spending hours on my sample code. You should learn java.nio.files.* and java.time.* packages. Path API was introduced at Java 7 in 2011. java.time package was introduced at Java 8 in 2014. Older books that lack java.nio.files.* and java.time.* coverage would not help.
I was just curious to see your result.
I added the dateTime to the path I was using and I was able to save with time stamp.
Thank you again for your advice 
public class naming {
private static ZoneOffset myZoneOffset = ZoneOffset.of("+0200")
private static DateTimeFormatter dtFormatter = DateTimeFormatter.ofPattern(“dd.MM.yyyy-hh.mm.ss”)
@Keyword
public void screenshotNaming(String path, String name){
LocalDateTime now = LocalDateTime.now(myZoneOffset)
String dateTime = dtFormatter.format(now)
String completePath = path + name + dateTime + ".jpg"
println WebUI.takeScreenshot(completePath);
}
Does the screenshotName() method work ok or not? Are you asking me anything more?
String completePath = path + name + dateTime + ".jpg"
println WebUI.takeScreenshot(completePath);
I am curious. WebUI.takeScreenthos() keyword create a PNG file, not a JPEG file. Why do you name the file as .jpg instead of .png?
Everything works, thank you
Good point, I did’t actually consider that.
