问题


I know that Selenium is an automated testing tool, but i'm trying to use it for RPA instead (things to do with my work environment)

I've gotten the java code down, and it runs exactly how i want it. It takes data from an excel sheet, converts the data into java objects, then enters data into a web application. It works fine for the first 20-25 entries, then starts to slow down, and eventually crashes the application. I have a few thousand rows to enter.

I've tried starting the chrome webdriver with disabled cache, but doesn't solve the problem.

Here is the code for disabling the cache.

System.setProperty("webdriver.chrome.driver","C:\\\\DRIVERS\\\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability("applicationCacheEnabled", false);
WebDriver webDriver = new ChromeDriver(cap);
WebDriverWait wait = new WebDriverWait(webDriver, 20);
JavascriptExecutor js = (JavascriptExecutor) webDriver;

I'm using a for each loop to key in the data.

/* Add vehicle data */
            for(VehicleData vehicleData : testDataList) {

                Thread.sleep(2500);

                /* Add new inspection */

                webDriver.findElement(By.xpath("/html/body/app-component/div/div/mat-sidenav-container/mat-sidenav-content/div[1]/div[2]/count-survey-component/count-survey-vehicle/div[2]/div/mat-tab-group/div/mat-tab-body[1]/div/div[2]/div/div/button")).click();

                js.executeScript("window.scrollBy(0,-1000)");

                DateTimeFormatter dtf = DateTimeFormatter.ofPattern("dd/MM/yyyy");
                LocalDateTime now = LocalDateTime.now();
                String inspectionDate = dtf.format(now).toString();

                Thread.sleep(5000);

                webDriver.findElement(By.name("InspectionDate")).click();
                webDriver.findElement(By.name("InspectionDate")).sendKeys(inspectionDate);

I've read that this happens when trying to open Chrome DevTools during the test, but my code does not do that at all. Please advise.

Is it an issue with the chrome cache filling up? If so, must i clear it every 30 or so entries?

This error message...

org.openqa.selenium.WebDriverException: disconnected: received Inspector.detached event

...implies that the WebDriverException was raised due to Inspector.detached event.

From your code trials it is pretty much evident you were using Thread.sleep(n); to wait for the elements to be clickable / interacable to invoke sendKeys() which is not the ideal way, as:

Thread.sleep() suspends the execution of the current thread for the given number of seconds. The argument may be a floating point number to indicate a more precise sleep time. The actual suspension time may be less than that requested because any caught signal will terminate the sleep() following execution of that signal’s catching routine. Also, the suspension time may be longer than requested by an arbitrary amount because of the scheduling of other activity in the system.

Invoking sendKeys() and Thread.sleep() back to back might have simulated sending either of the following:

  • Ctrl + Shift + I
  • Ctrl + Shift + J
  • Ctrl + Shift + C
  • F12

each of which will attempt to open the google-chrome-devtools

Now, as per the article DevTools window keeps closing if you try to open the google-chrome-devtools, ChromeDriver is automatically disconnected.

Solution

A full proof solution will be to replace all the instances of Thread.sleep() and ImplicitWait with ExplicitWait

Additional Consideration

As per the documentation of DesiredCapabilities, the applicationCacheEnabled is a read/write capability which takes a boolean value and configures whether the session can interact with the application cache.

Implementation

applicationCacheEnabled can be configured in either of the ways:

DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability("applicationCacheEnabled", false);

Or

DesiredCapabilities capability = DesiredCapabilities.chrome();
capability.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, false);

So effectively your code block will be:

System.setProperty("webdriver.chrome.driver","C:\\DRIVERS\\chromedriver.exe");
DesiredCapabilities cap = DesiredCapabilities.chrome();
cap.setCapability(CapabilityType.SUPPORTS_APPLICATION_CACHE, false);
ChromeOptions opt = new ChromeOptions();
opt.merge(cap);
WebDriver driver = new ChromeDriver(opt);

Just add this line:

chromeOptions.setPageLoadStrategy(PageLoadStrategy.NONE);

This should solve the problem.
