Best practices for exception handling with Selenium

Question

I've been searching on google for best practices regarding exception handling, however I did not have much success besides using try-catch.

My framework is set with a EventFiringWebDriverwhich, according to Selenium documentation has a ExceptionThrownevent.

I was thinking in implementing it so we can quickly debug the method that threw the exception, as some colleagues are not programmers and don't know a lot about coding.

The other idea I had is adding try-catchto each method but this seems like a really tedious and worthless endeavour as I would've to keep adding try-catchs to each new method.

So my question is, do you have any best practices regarding exception handling?

Answer 1

Here are few best practices regarding exception handling in general:

• Close/Clean Up Resources in a Finally Block (Not at the end of the try block).
• Use specific exceptions over generic one so that person maintaining the code will have an easier time figuring out issues.
• Mention the exception detail in the function header comment with the situation it may occur.
• Provide descriptive message while throwing Exceptions
• Catch the Most Specific Exception First.
• Don't Catch Throwable.
• Don't Ignore Exceptions.
• Don't Log and Throw.
