Try-Catch无法捕获“ System.setProperty”中的错误

Question

I am using Selenium and Java to write a test, I added the code below to see if I am using a wrong Chrome driver,

  try {
    System.setProperty("webdriver.chrome.driver", "Chrome Drivers\\chromedriverLinux32");
        } catch (Exception e) { 
            System.out.println(1);
            e.printStackTrace();    
        }

but whenever it happens, the test throws:

Jan 14, 2016 11:04:25 AM org.openqa.selenium.os.UnixProcess checkForErrorSEVERE: org.apache.commons.exec.ExecuteException: Execution failed (Exit value: -559038737. Caused by java.io.IOException: Cannot run program "C:\Users\sina\Desktop\WorkSpace\CowZAllPages\Chrome Drivers\chromedriverLinux32" (in directory "."): CreateProcess error=193, %1 is not a valid Win32 application)

But the catch does catch any errors ( System.out.println(1); is not seen).

Answer 1

There's nothing wrong with your code in the way you assign the Chrome Path. The System literally gets that string.
You'll want to have a look at the driver initialization and put a try-catch there, in order to catch such exceptions.

Update:
Perhaps you need to revise this use case - in the sense that you can have 3 ChromeDriver paths and use the right one depending on the platform.

System.getProperty("os.name")

This way, you'll always use the right ChromeDriver.

Answer 2

The last part of the error says "not a valid Win32 application". Is "Chrome Drivers\\chromedriverLinux32" an .exe? Do you need to add the file extension?
