Performance / Load Testing:
Need to know how your website will perform under peak load? Our load test engineers are certified in the use of sophisticated stress testing tools designed to tell you the “breaking point” of your servers’ acceptable performance.
Automated Testing:
We have automated test engineers skilled in the use of the powerful automated test tools. These tools enable them to write complex test scripts designed toi automate parts of the testing process thereby significantly reducing the necessity for manual testing.
Regression Testing:
As the testing effort proceeds, fixes can sometimes lead to new problems. Our regression testing techniques allow us to carefully track both old issues as well as new. We assume nothing. Upon receipt of new project builds, we regress old issues and go over old ground to make sure that new, unexpected bugs do not pop up.
Game/Multimedia Testing:
Testing games involves more than just the systematic, formal testing approach that is used for business applications and the like. Games are not as straightforward as is used for business applications and the like. Games are not as straightforward as business applications. Games are not designed to be easy, yet should not be too hard, especially in the beginning. Games should conform to a certain genre of standards and expectations, but should also be creative and different. A game must be much, much more than just “presentable” or “functional” – a game must be fun. Attention must be paid to the game’s adherence to reality, both logically and graphically. Vr4Web Solution understands all of these points and brings our considerable testing experience to game developers coast-to-coast. Our test engineers will find the flaws in your games whether they are designed to run on PC’s or consoles. Hire Vr4Web Solution and keep those technical support lights out.
Client/Server LAN Driven Applications Testing:
Whether you are developing an application designed to run a basic workgroup or robust multi-level domain environment, assuring your software is compatible with common client/server operating system combinations, networking protocols and network topologies is a must. At Vr4Web Solution, we have the most popular server operating systems, client operating systems and networking hardware. Backed by years of experience, our industry certified technicians simulate the network environments encountered in today’s marketplace.
Wireless Applications Testing:
Also included in our full spectrum of quality assurance services is Wireless Application Protocol (WAP) testing. Although still a relatively new technology, Vr4Web Solution has in our vast library of hardware WAP enabled mobile phones. In an ongoing effort to keep up with today’s technology we also maintain a line of Personal Digital Assistant (PDA) devices and modems.
WEBSITE ARCHITECTURE
A Website can be complex, and that complexity — which is what provides the power; of course can be an impediment in assuring Website Quality. Add in the possibilities of multiple authors, very-rapid updates and changes, and the problem compounds.
Here are the major parts of Websites as seen from a Quality perspective.
Browser. The browser is the viewer of a Website and there are so many different browsers and browser options that a well-done Website is probably designed to look good on 35 many browsers as possible. This imposes a kind of de facto standard: the Website must use only those constructs that work with the majority of browsers. But this still leaves room for a lot of creativity, and a range of technical difficulties.
Display Technologies. What you see in your browser is actually composed from many sources:
• HTML There are various versions of HTML supported, and the Website ought to be built in a version of HTML that is compatible. And this should be checkable.
• Java, JavaScript, ActiveX. Obviously JavaScript and Java applets will be part of any serious Website, so the quality process must be able to support these. On the Windows side, ActiveX controls have to be handled as well.
• Cgi-Bin Scripts. This is link from a user action of some kind (typically, from a FORM passage or otherwise directly from the HTML, and possibly also from within a java applet). AH have the different types of Cgi-Bin Scripts (peri, awk, shell-scripts, etc.) need to be handled, and tests need to check "end to end" operation. This kind of a "loop" check is crucial for
E-commerce situations.
• Database Access. In E-commerce applications either you are building data up or retrieving data from a database. How does that interaction perform in real world use? If you give in "correct" or "specified11 input does the result produce what you expect? Some access to information from the database may be appropriate, depending on the application, but this is typically found by other means.
Navigation. Users move to and from pages, click on links, click on images (thumbnails), etc. Navigation in a Website often is complex and has to be quick and error free.
Object Mode. The display you see changes dynamically; the only constants are the "objects" that make up the display. These aren't real objects in the 00 sense; but they have to be treated that way. So, the quality test tools have to be able to handle URL links, forms, tables, anchors, buttons of all types in an "object like" manner so that validations are independent of representation,
Server Response. How fast the Website host responds influences whether a user (i.e. someone on the browser) moves on or continues. Obviously, Internet loading affects this too, but this factor is often outside the Webmaster's control at least in terms of how the Website is written. Instead, it seems to be more an issue of server hardware capacity and throughput. Yet, if a Website becomes very popular — this can happen overnight! — Loading and tuning are real issues that often Ana imposed — perhaps not fairly — on the Webmaster.
Interaction & Feedback. For passive, content-only sites the only issue is availability, but for a Website that interacts with the user, how fast and how reliable that interaction is can be a big factor.
Concurrent Users. Do multiple users interact on a Website? Can they get in each other’s way? While Websites often resemble conventional client/server software structures, with multiple users at multiple locations a Website can be much different, and much more complex, than complex applications.
