java - How to close IEDriverServer.exe in selenium? -

i have program opens desired url in ie using selenium driver. want close driver exe after url loading.
i used driver.quit(); results cleaning exe , closing browser. don't want close opened browser
there way achieve without using runtime.getruntime().exec("taskkill /f /im iedriverserver.exe");?

helium automatically - if haven't called driver.quit(); when jvm terminates, helium leaves browser window open cleans driver exe.

here's how implementation works: selenium class driverservice manages driver.exe process. need manipulate fields of correct driverservice instance shut down exe. fields not accessible default, need use java reflection access them.

first, when starting ie, need manually pass in driverservice instance:

internetexplorerdriverservice.builder servicebuilder = new internetexplorerdriverservice.builder().usinganyfreeport(); internetexplorerdriverservice service = servicebuilder.build(); webdriver ie = new internetexplorerdriver(service); // open url: ie.get("http://www.google.com"); 

to kill driver exe, first need obtain service's lock field. not public need use reflection access it:

field lockfield = driverservice.class.getdeclaredfield("lock"); lockfield.setaccessible(true); reentrantlock lock = (reentrantlock) lockfield.get(service); 

the lock used prevent concurrent access driver exe. safely access driver exe, need wrap rest of code in try ... finally block:

try {     lock.lock();     [...] } {     lock.unlock(); } 

now [...]: need access process field, again via reflection:

field processfield = driverservice.class.getdeclaredfield("process"); processfield.setaccessible(true); commandline process = (commandline) processfield.get(service); 

it may happen process null, in case can't anything:

if (process == null)     return; 

otherwise, call process.destroy() - kills driver exe process:

process.destroy(); 

... , set process null:

processfield.set(service, null); 

that's it! it's of stuff going on behind helium's startie(...) command.
