In this article, we will learn about the fundamentals of software testing by the help of unittest module available in Python 3.x. Or earlier. It allows automation, sharing of the setup and exit code for tests, and independent tests for every framework.In unit test, we use a wide variety of object oriented concepts. We will be discussing some majorly used concepts here.Testcase − It is response specific base class in accordance with a given set of inputs. We use base class of unittest i.e. “TestCase” to implement this operation.Testsuite − It is used to club test cases together and execute ... Read More
It is a general thumb rule that though you can catch all exceptions using code like below, you shouldn’t:try: #do_something() except: print "Exception Caught!"However, this will also catch exceptions like KeyboardInterrupt we may not be interested in. Unless you re-raise the exception right away – we will not be able to catch the exceptions:try: f = open('file.txt') s = f.readline() i = int(s.strip()) except IOError as (errno, strerror): print "I/O error({0}): {1}".format(errno, strerror) except ValueError: print "Could not convert data to an integer." except: ...

The HTML onload event attribute is triggered when an object has been loaded in an HTML document.SyntaxFollowing is the syntax −Let us see an example of HTML onload event Attribute−Example Live Demo body { color: #000; height: 100vh; background-color: #FBAB7E; background-image: linear-gradient(62deg, #FBAB7E 0%, #F7CE68 100%); text-align: center; padding: 20px; } function get() { alert("Hi! you just refresh the document."); } HTML onload Event Attribute Demo Now try to refresh this document. OutputNow try to reload the document to observe how onload event attribute works.
Only a single except clause in a try block is invoked. If you want the exception to be caught higher up then you will need to use nested try blocks.Let us write 2 try...except blocks like this:try: try: 1/0 except ArithmeticError as e: if str(e) == "Zero division": print ("thumbs up") else: raise except Exception as err: print ("thumbs down") raise errwe get the following outputthumbs down Traceback (most recent call last): File "C:/Users/TutorialsPoint1/~.py", line 11, in raise err File "C:/Users/TutorialsPoint1/~.py", line 3, in 1/0 ZeroDivisionError: division by zeroAs per python tutorial there is one and only one ...
