Powerful Web Testing Tools

Web testing; Nowadays meant to be very crucial, so many Internet browsers and their supporters. Numerous tools available for web testing most of them require higher budget. Few free website testing tools are available online or as add-ones for example firebug,Yslow. These are not only used for web development also for web testing. We can fetch object details ,CSS, JavaScript and more using these kinds of add ones. It is easy to analyze all these information. Open source Testing tools like Selenium, Watir needs web object’s physical properties or it’s description to run successfully, we can use these tools as an object spy.Checkout some powerful web testing tools

1.Firebug
Firebug integrates with Firefox, it is a great invention for developers can find JavaScript errors , page loading time etc. Most of the developers used to fix Html/CSS, JavaScript errors simply in your finger tips while you browse. Firebug is one of the best applications around for debugging issues with front-end code and CSS. If there’s any image or style that’s out of line, checking it out with Firebug is the best response. It’s even possible to change styles within the extension to see how a website will actually appear in the browser. How this is useful in web testing. We can monitor java script errors, web site performance i.e. site loading time/object wise also Html or CSS validation. Inspect elements option in firebug is like GUI Spy.

2. YSlow
YSlow analyzes web pages and suggests ways to improve their performance based on a set of rules for high performance web pages. YSlow is a Firefox add-on integrated with the Firebug web development tool. YSlow grades web page based on one of three predefined ruleset or a user-defined ruleset. It offers suggestions for improving the page’s performance, summarizes the page’s components, displays statistics about the page, and provides tools for performance analysis, including Smush.it and JSLint.

3. Load Impact (Online testing)
This is used for Performance Testing (Load/Stress). It simulates users and access your website . It simulates large user load on web servers to determine whether or not they can handle the high traffic load. Free users can only attempt using 50 simulated users But this is very useful . The tool will check (ping) from different locations and results will display as a complete report with graphs

API (Application Programming Interface)

An API (Application Programming Interface) is a collection of software functions and procedures, called API calls, that can be executed by other software applications. Application developers code that links to existing APIs to make use of their functionality. This link is seamless and end-users of the application are generally unaware of using a separately developed API.

Bug Priority

Priority indicates how important it is to fix the bug and when it should be fixed
Immediate Priority: The bug is of immediate priority if it blocks further testing and is very visible
At the earliest Priority: The bug must be fixed at the earliest before the product is released
Normal Priority: The bug should be fixed if time permits
Later Priority: The bug may be fixed, but can be released as it is

Black Box or Functional Testing

Black Box Testing is testing without knowledge of the internal workings of the item being tested. The Outside world comes into contact with the test items, only through the application interface, an internal module interface, or the INPUT/OUTPUT description of a batch process. They check whether interface definitions are adhered to in all situations and whether the product conforms to all fixed requirements. Test cases are created based on the task descriptions
Black Box Testing assumes that the tester does not know anything about the application that is going to be tested. The tester needs to understand what the program should do, and this is achieved through the business requirements and meeting and talking with users.
Functional testing: This type of tests will evaluate a specific operating condition using inputs and validating results. Functional tests are designed to test boundaries. A combination of correct and incorrect data should be used in this type of test.

Web Testing- Functional System Testing

System tests check that the software functions properly from end-to-end. The components of the system include: A database, Web-enable application software modules, Web servers, Web-enabled application frameworks deploy Web browser software, TCP/IP networking routers, media servers to stream audio and video, and messaging services for email. A common mistake of test professionals is to believe that they are conducting system tests while they are actually testing a single component of the system. For example, checking that the Web server returns a page is not a system test if the page contains only a static HTML page

Web Testing- Click-Stream Measurement Testing

Makes a request for a set of Web pages and records statistics about the response; including total page views per hour, total hits per week, total user sessions per week, and derivatives of these numbers. The downside is that if your Web-enabled application takes twice as many pages as it should for a user to complete his or her goal; the click stream test makes it look as though your Web site is popular, while to the user your Web site is frustrating

Web Testing- Online Help Testing

Online help tests check the accuracy of help contents, correctness of features in the help system, and functionality of the help system

Web Testing- Click-Stream Testing

Click stream Testing is to show which URLs the user clicked, The Web site’s user activity by time period during the day, and other data otherwise found in the Web server logs. Popular choice for Click-Stream Testing statistics include Keynote Systems Internet weather report, Web Trends log analysis utility, and the Net Mechanic monitoring service.
Disadvantage: Click-Stream Testing statistics reveal almost nothing about the user’s ability to achieve their goals using the Web site. For example, a Web site may show a million page views, but 35% of the page views may simply e pages with the message “Found no search results,” With Click-Stream Testing, there’s no way to tell when user reach their goals

Web Testing- Security Testing

Security measures protect Web systems from both internal and external threats. E-commerce concerns and the growing popularity of Web-based applications have made security testing increasingly relevant. Security tests determine whether a company’s security policies have been properly implemented; they evaluate the functionality of existing systems, not whether the security policies that have been implemented are appropriate
Primary task in security testing over web applications

• Application software
• Database
• Servers
• Client workstations
• Networks

Web Testing – External Beta Testing

External beta testing offers developers their first glimpse at how users may actually interact with a program. Copies of the program or a test URL, sometimes accompanied with letter of instruction, are sent out to a group of volunteers who try out the program and respond to questions in the letter. Beta testing is black-box, real-world testing. Beta testing can be difficult to manage, and the feedback that it generates normally comes too late in the development process to contribute to improved usability and functionality. External beta-tester feedback may be reflected in a future releases.
