- Web Security Testing
For More Details Check Below:
 Functionality Testing
The following testing must be carried out while doing Website Functionality testing:
- You should make sure that if the valid HTML used for your website. To check this, you can use the W3C validator.
- In functionality testing, the different fields used on the website should be validated like Textboxes, dropdowns, radio options, checkboxes, Combo box inputs, links, etc.

Such a link generated with the spelling mistakes in the link URL or linked page is removed or no more exists. To check the broken link, you can use online tools to validate the broken links on the website.
In the Website Testing Checklist, the web forms are the most commonly used in the websites, so it is one of the most important parts of the website testing. Consider a scenario where a user fills an inquiry form and click on Submit button, now what next or they fill in the form and do nothing, the details do not get captured correctly and so are lost. While doing forms, functional testing makes sure that they should be consistent and should contain the required input and output controls. The data should be appropriately captured.
Nowadays, with new technologies like Android and smartphones, computer applications are more complex.
If the front end is more complicated, then the backends are also convoluted. As a result, introduce more complex database schema to support such intricate computer applications. So it’s more important to validate the databases to make sure the quality and website able to handle the data processing efficiency.
The cookie is information stored in the text file on the user’s hard drive (client-side) by the webserver. This information is used later by web browser while accessing the website. Ideally, the cookie is used to store the personalised user information or data in an encrypted or secure manner. This is small size files which act as unique identifiers and allow websites to remember a particular user for a given time. These files are not harmful to users. Sometimes if the user’s personal information is stored in the cookie and if hackers stole the cookie the then the hacker can get the confidential information which leads to security issues. That’s why the testing of Cookie is the most important. There are two types of cookies Persistent Cookie and Non-Persistent Cookie.
Testing of Error Messages
In the well-developed website, the error messages are very much helpful to guide users to success and erroneous conditions. While navigating through the application if poorly designed error messages will easily misguide the end-users. Many of the websites are used different interesting pages when 404 error is displayed.
Required field and optional field validation
The proper handling of required and optional fields should be efficiently handled. Ideally, the application should not be submitted unless and until all required fields are correctly filled. The required error message should be displayed when the user proceeds with not filling the mandatory fields. It should not restrict you from proceeding further if the optional fields are not filled.
This type of testing is a subset of Security testing. In this testing need to check if the sensitive modafinil online sale data is not stored in the temporary internet files or stored in an encrypted format like passwords, credit card information, bank number, etc.
 Performance Testing
Software Performance testing is a type of testing performed to determine the performance of the system to major the measure, validate or verify quality attributes of the system like responsiveness, Speed, Scalability, Stability under a variety of load conditions. The main aim of Performance testing is not to find the defects in the application but to get rid of bottlenecks and find out the amount of load/stress the site can sustain. Performance testing is used to understand the scalability of an application under test, and response time means the time required to send request from the client machine to the time required to reply by the server under the different variety of load conditions which mimic the real-world use.
Performance testing can be applied to understand the web site’s scalability, any loopholes in the load balancing and to test the response time between a request (from the client) and the reply (from the server) and the amount of load/stress the site can sustain.
 Web Usability Testing
The Usability Testing is coming from a Black Box Testing Technique where testing is to be carried out with users point of view. It is a technique implemented in user-centred interaction design to evaluate a product or service by testing it with representative users. On the Web page, the usability is the most important and required condition for survival. If the website is difficult to use, then, peoples will not stay on the page. Also, if the content or details of the page are difficult to read or understand, then also peoples will not stay on the page. So Usability testing plays an important role which assesses how easy user interfaces is to use.

- Here is the most typical compatibility tests should be considered while testing your application:» Check on different browsers and its versions.» Check on different Operating systems and its versions.
» Check on different hardware configurations
» Check on different network environments.
» Check on different screen resolutions
 Web Security Testing
Security testing is one of the most important types of software testing that make sure that the vulnerabilities or weakness of the software application. The main objective of security testing is to find the vulnerabilities of the system & determine that its data and resources are protected from the possible intruder.
