Selenium Webdriver Tool - Limitations

Posted by Infocampus HR on January 19th, 2019

Organizations are receiving increasingly more open source choices for making home-grown test structures. Selenium has turned into a sort of true standard in this space. The adaptability of altering the system through programming to suit one's venture needs is a key behind prominence of Selenium Web Driver.

Selenium is the pennant for a lot of open-source ventures - a gathering of instruments. The Selenium Integrated Development Environment or "Selenium IDE" is a FireFox module that records and spares client activities and enables you to play them back - in FireFox just, without any circles or other programming structures. Selenium IDE "tests" are basic snap click examine schedules. The instrument provides the capacity to send out code to Selenium WebDriver. Selenium IDE is anything but difficult to learn, not incredible, and gives a direct move up to something more grounded; you can consider it the preparation wheels of the toolset.

With expanded interest of FastIT, Agile practices and DevOps it is the need of time to re-examine the manner in which we create and test the product. New period of programming testing is driving us towards 'Test Driven Development' and 'Conduct Driven Development' for example TDD and BDD where testing rehearses lead improvement process. Considering this quick change, programming Testers ought to learn Selenium Courses in Bangalore sound manual programming testing rehearses as well as need to move their emphasis more on computerization and test structure plan.

The Limits of Selenium WebDriver:-

Remember that Selenium just does program computerization, not all that much. Conventional Windows applications like Word and Excel don't keep running in a program, so WebDriver won't have the capacity to see or connect with them. (On the off chance that you compose a Windows application, you won't have the capacity to utilize Selenium to drive it.) That's a direct result of how WebDriver functions - it controls site pages inside the program, utilizing a similar motor that deciphers site pages. Working framework click occasions, similar to the F(ile), E(dit), V(iew) menu, are avoided Selenium's view.

In like manner, the device can't see questions that show up in a site page however are not HTML, similar to PDF's and Java applets. One basic example for tests is to change an incentive in Excel, spare the spreadsheet, at that point transfer the spreadsheet. Another is to print the website page as a PDF and view it to look at how printouts show up. Since WebDriver can't see outside the program, it won't have the capacity to do these errands. Regardless of whether it could, Selenium works by checking content and connection esteems - it doesn't do picture think about. That implies the content could be the wrong size, or in the wrong place, and WebDriver will at present report achievement. (It is conceivable to expressly check text dimension and shading, however few individuals do.) Let's investigate a few reasons you may pick Selenium as your device to computerize program checks, and a couple of methodologies for you to consider.

Selenium does not scale well in its program testing capacities. The Selenium Grid exists, to turn up a circulated system of Selenium examples, enabling you to run tests simultaneously, however it is both hard and costly to keep up. You can run your selenium testing in the cloud administrations like CrossBrowserTesting.

Complex Choices:

At its most fundamental dimension, Selenium is an application programming interface (API). When you've settled on utilizing the instrument, despite everything you need to make sense of what approach bodes well. The methodology you pick is firmly identified with the issues you are endeavoring to fathom; these quandaries may enable you to settle on that choice.

Unadulterated versus Building Blocks:

Starting with IDE or straight up WebDriver is the least complex methodology and will give the most prompt outcomes. The result of these two choices is entirely comparative; analyzers create singular contents that have a great deal of copied code. This can be suitable on a few groups, however will in general lead to specialized obligation and upkeep issues. WebDriver code is, all things considered, code, and may best be made by generation software engineers. The issue with this methodology is that composition test code implies not composing generation code, which backs off the venture quickly in the desire for speeding it up later. The building squares approach sits in the center.

Software engineers make the building squares, regularly called a Domain Specific Language, or DSL. The DSL is a wrapper around selenium that permits non-software engineers to compose incredibly abnormal state code in something that is near English. All the more critically, your group can utilize the DSL idea to make a dialect in the space of your item. For instance on the off chance that you are composing selenium training in Bangalore a checks for a library site, you may compose capacities checkOutBook, checkInBook, and searchInventory. Likewise, it's decent not having to more than once program: click this, type, click this, type.

Enormous versus Little:

Another imperative decision to make is the means by which huge or little the utilization of WebDriver will be, the amount of the procedure to robotize. It's normal, for instance, for groups to set out an objective to robotize the whole test process, which sounds great in principle yet can be costly and fragile practically speaking - particularly if the UI is experiencing nonstop change. Indeed, even with a DSL, your group will achieve a point where the measure of time spent on upkeep is equivalent to or more prominent than the measure of time they are spending making new checks and increasing the value of the venture. With your item changes, the DSL should switch to stay aware of that, and the contents switch to stay aware of the DSL, and at times you'll have Selenium and program refreshes also.
