Selenium to perform Test Automation and its Uses & Flaws
Automated functional testing is one of the most valuable tools your organization can implement.
You get the benefit of having repeatable, fast running tests that do not require expensive humans
to run them and are less error prone. I’m a big fan of anything that can be done for me while I’m
sleeping.
Selenium IDE in an integrated development environment which tests code while integrating browser
activity. The main ambition of writing these types of tests is to mimic user actions to determine
if the web server and database are behaving as expected as they carry out the users’ commands.
Documents are the heart of selenium tests. These commands are a way of knowing what part of the
application is being tested and what the user expects the browser to present. Writing tests is almost simple with selenium. The end product of a selenium test can be transformed to any language, however, by default, selenium scripts are simply a combination of “Selenese” commands in an HTML format. However, by creating or downloading a user extension, JavaScript commands may
also be implemented. User extensions themselves are created with JavaScript by adding methods to
the Selenium object prototype. More insights of this automation testing can be gained from
Selenium training through online learning.
Selenium's Uses & Flaws:
Selenium is a tool for looking at an installation and trying to break it and filing bug reports,
maybe in a mechanized way -- in other words, integration testing. But automated integration
testing, as we've now experienced, frequently breaks; it's brittle, not robust. Selenium is an
automated tests framework suited to integration testing: you start Selenium and it fires up a
browser, performs scripted actions as a user would, and checks the actual output against the
desired output. But that means that we have to define the desired output in a way Selenium can
programmatically test, and so the tests break when we change things that actual users wouldn't
care about.
For example, a test might define success as "this DIV should have the value 1". If we change the
skin to output a SPAN element instead of a DIV element, then the test will fail. And even if a
failed test is a legitimate signal of a problem, we have to start from scratch investigating what
to fix and how.
