当无法通过“系统属性”或“路径”指定壁虎驱动程序位置时，是否有一种非远程的方式来指定它？

Question

In my application I cannot set geckodriver executable location using System.setProperty and I cannot set it in the path.

Why? Because my app is multi-tenant... and each tenant has their own directory where Firefox and Geckodriver is copied and ran. This is due to bugs in the Firefox + Geckodriver, where infinite javascript loops and several other situations cause Firefox to hang until manual kill. Sometimes quit fails to kill things completely as well. So we need to supply a custom geckodriver location within the JVM per-tenant . Thus the problem.

So I am instead using:

driverService = new GeckoDriverService.Builder()
          .usingDriverExecutable(new File(geckoDriverBinaryPath))
          .build();
driverService.start();
RemoteWebDriver driver = new RemoteWebDriver(driverServiceUrl, capabilities);

But that is making me use a RemoteWebDriver when I am not remote.

Is there a better way to do this?

Answer 1

Rather than calling start() on the FirefoxDriverService object, why not simply use the FirefoxDriver constructor that takes the service?

driverService = new GeckoDriverService.Builder()
      .usingDriverExecutable(new File(geckoDriverBinaryPath))
      .build();
WebDriver driver = new FirefoxDriver(driverService);

Answer 2

As the questions stands it is still too broad. There are some unknowns: How are you running this? JUnit?, Maven?, Jenkins? And I am still not clear where this per-tenat geckoDriverBinaryPath comes from and how it is passed around.

What is wrong with just using:

System.setProperty("webdriver.gecko.driver", geckoDriverBinaryPath);

You could set an environment variable in your OS. Something like export geckoDriverBinary=/some/path and then in your code read it back using:

String geckoDriverBinaryPath = System.getenv("geckoDriverBinary");
System.setProperty("webdriver.gecko.driver", geckoDriverBinaryPath);
...

If you are running it from command line, either straight up or using Maven, you could pass the variable in like -DgeckoDriverBinaryPath=/some/path and then in your code read it back using:

String geckoDriverBinaryPath = System.getProperty("geckoDriverBinary");
System.setProperty("webdriver.gecko.driver", geckoDriverBinaryPath);
...

If the different tenants have the path fixed, you could write a utility function that would detect which tenant it is being run on, and set the property accordingly.

This answer is probably going to get closed as not-answer, but more of a discussion. :(
