How to shut down the ChromeDriver service?

Question

I’ve been trying to shut down the ChromeDriver service for some time now, and I cannot develop a solution on how to do this. I use unit test using mocha and tea. The first test passes, and the second because of an error.

I tried looking in the selenium-webdrive / chrome.js module and could not find the function to close the service. I tried to find the answers, but did not find anything on the Internet. Perhaps my approach to creating the chrome driver needs to be redone. I tried to wrap the service creation and setting the default service in an if statement using the selenium-webdriver / chrome.js.getDefaultService () command. IsRunning (), but it did not pass the first test. I am confused by this, and this is most likely due to a lack of knowledge.

This call block is called during each unit test.

var service = new chrome.ServiceBuilder(chromePath).build(); chrome.setDefaultService(service); driver = new webdriver.Builder() .withCapabilities(webdriver.Capabilities.chrome()) .build(); 

This is the first unit test that passes without errors.

 it('Should pass if the Driver is set to equal the Chrome driver by using chrome', function() { var chromeDriver = Driver( { browserName: 'chrome' } ); expect(chromeDriver.getCapabilities().browserName).to.equal('Google Chrome'); }); 

This is the second unit test, which leads to failure

 it('Should pass if the Driver is set to equal the Chrome driver by using google chrome', function() { var chromeDriver = Driver( { browserName: 'google chrome' } ); expect(chromeDriver.getCapabilities().browserName).to.equal('Google Chrome'); }); 

Error message:

 Error: The previously configured ChromeDriver service is still running.

Answer 1

Try this command from CMD:

 taskkill /T /F /IM chromeserver.exe 

When I use selenium to execute automation scripts, every time a new instance of this driver appears (which you can see if you open the task manager).

I use Java for scripting, so I add this line to kill any active tasks at the beginning of my test:

 Runtime.getRuntime().exec("taskkill /T /F /IM chromedriver.exe");
