Is Selenium best for Functionality testing?
Selenium is widely used for testing web applications. Various web testing techniques have been developed for web application testing. Functionality testing is most widely used web testing technique and it is believed that Selenium is best for this type of testing. Before talking about Functionality testing let me attempt to define web testing.
What’s web testing?
Web application needs to be checked for potential bugs before it is made live. This process is called web testing. Web testing process is very complex and many different types of web testing techniques have been developed to simplify this process as far as possible. Site functionality, security of web application, accessibility and traffic handling ability is checked at web testing stage.
Functionality testing
Functionality testing is used to check if the website adheres to specifications and functional requirements charted out for it in developmental documentation. Web testing activities used in this technique:
· All types of links i.e. outgoing links, internal links, anchor links and mail to links on various web pages need to be checked to make sure that all these are working.
· Working of Test Forms needs to be checked. This step includes following activities:
1. Scripting checks on the form are functioning correctly or not. For example- if a user leaves a mandatory field empty then error message is shown or not.
2. Default values are being populated or not needs to be checked
3. Data submitted in the forms is generally linked to a working email address or goes to a live database. It needs to be checked that this is happening or not.
4. Readability and formatting of forms needs to be checked for best results.
· Working of Cookies needs to be checked. Every websites uses small files called cookies meant to help users by remembering active user sessions so that he or she doesn’t need to log in on every visit to website. Cookie Testing activities are as follows:
1. When cache is cleared cookies should get deleted. It needs to be tested that this is happening or not.
2. It also needs to be tested that login credentials are asked for after deleting cookies or not.
· CSS and HTML need to be tested to make sure that search engines can crawl the website easily. Activities included in this step are as follows:
1. Syntax Errors checking
2. It needs to be checked that color scheme ensures good readability or not.
3. Standards such as ISO, ECMA, W3C, OASIS, IETF or WS-I need to followed and compliance to these standards need to be checked.
· Business workflow of the website needs to be checked. Activities included in this step are as follows:
1. Users often need to go through multiple web pages for different business scenarios. Detailed testing of workflow for different business scenarios needs to be conducted.
2. When user executes erroneous step that breaks business workflow then error message or help message should appear. It needs to be checked that this happening or not.
Selenium is one of the best functionality testing tools and is great for core functional testing, usability testing, GUI testing, DB testing, Regression testing, Sanity testing, Cross browser testing, Business process testing and E2E testing. There is no dearth of options for Selenium training in Noida and many institutes are vying for best Selenium training institute in Noida tag.
