Dealing with popups in Selenium can sometimes be tricky, especially when encountering unusual behavior. I recently encountered a situation where I found it difficult to close a popup window after clicking a button.
Upon executing the code below:
WebElement button = driver.findElement(...);
log.info("step 1");
button.click();
log.info("step 2");
Alert alert = driver.switchTo().alert();
alert.accept();
WebElement nextButton = driver.findElement(...);
nextButton.click();
I noticed that the log did not display the "step 2" message. Moreover, Eclipse seemed to freeze after the button click, despite the fact that the click was successful and a subsequent popup appeared on the page.
Upon further investigation, I discovered that the button's onclick function contained the following JavaScript code:
continueButton();return;
It seemed that the popup window was being triggered from within the continueButton() function.
My theory is that my Java code was waiting for this JavaScript function to complete and return control. However, since the popup window was blocking the JavaScript execution, I couldn't proceed with closing the window programmatically. Interestingly, manually closing the window allowed the Java code to resume execution and the "step 2" message to appear in the log.
Given that I couldn't modify the page source, I attempted to run the JavaScript code separately, instead of simulating the click event:
jsexecutor.execute("continueButton();")
log.info("step 1");
Alert alert = driver.switchTo().alert();
alert.accept();
jsexecutor.execute("return;")
However, this approach resulted in the same behavior - the popup window appeared, but the "step 1" message was not logged, indicating that the Java execution was halted.
Is there a workaround for this issue that doesn't require changing the page source?
