How to use DevToolsException class of org.openqa.selenium.devtools package
Best Selenium code snippet using org.openqa.selenium.devtools.DevToolsException
DevToolsException org.openqa.selenium.devtools.DevToolsException
The DevToolsException usually found when any command is not supported by CDP (chrome devtool protocol) implementation which is a major part of Selenium 4
Recently this isssue surfaced with
Java 16as the underlying reflection machanism changes in Java 16 for selenium 4.0.0 alpha and beta which has been resolved in latest selenium versions
In Java 11, It only displays the Warning
INFO: Found CDP implementation for version 92 of 91 WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by org.openqa.selenium.json.InstanceCoercer (file://org/seleniumhq/selenium/selenium-json/4.0.0-beta-4/selenium-json-4.0.0-beta-4.jar) to constructor java.lang.Void() WARNING: Please consider reporting this to the maintainers of org.openqa.selenium.json.InstanceCoercer WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release
Example
It is an example code for capturing performance logs using Selenium 4 using Java 16.
