In C++, both assert.h and cassert headers provide the assert macro. The danger of assertions is that they may cause side effects either by changing memory data or by changing thread timing. Assertions should be implemented carefully so they cause no side effects on program code.

The goal of my test is to assert that a popup does not appear after certain actions. Previously to test if the popup exist, i have used exception handling. try: self.driver.find_element_by_id("fancybox-close").click() except Exception ('ElementNotVisibleException'): print "No popup" This works fine for the test : to assert if popup exists.

assert is to document your assumptions in the code. if statement is to handle different logical scenarios. Now in your specific case, think from 

There are various types of assertions like Boolean, Null, Identical etc. Junit provides a class named Assert, which provides a bunch of assertion methods useful in writing The function assert () was inspired by stopifnot (). It emits a message in case of errors, which can be a helpful hint for diagnosing the errors ( stopifnot () only prints … format : assert Expression[,arguments] When assert encounters a statement,Python evaluates the expression.If the statement is not true,an exception is raised(assertionError). If the assertion fails, Python uses ArgumentExpression as the argument for the AssertionError.

Assertions are simply boolean expressions that check if the conditions return true or not. If it is true, the program does nothing and moves to the next line of code. However, if it's false, the program stops and throws an error. It is also a debugging tool as it halts the program as soon as an error occurs and displays it.

Because asserts are usually macros, you can also get code information about the failing assertion. Assert is more semantically clear than if (). Typically, the Assert (Boolean) method is used to identify logic errors during program development. Assert evaluates the condition. If the result is false, it sends a failure message to the Listeners collection. You can customize this behavior by adding a TraceListener to, or removing one from, the Listeners collection.
