There are various phases in software development life cycle (SDLC). Software performance testing is one of the most essential stages. A variety of testing methods are used beginning with the application’s development until it gets the marketing stage. From the initial development of the application until it reaches the maketing phase different testing types will be used. In addition, all the different versions of the software have to be tested before they are delivered to either the costumer or the target market.

Software for web applications is one type of software. The importance of this type of software has increased rapidly since the arrival of the Internet. The majority of the security threats start off from Internet and it is necessary to make sure that the web software is carefully tested prior to releasing to the costumer.

Even though the testing of web software is vital, there is at all times rush in building and testing those application due to time constraints. The different types of tests can be grouped in code testing, [load testing], compatibility testing, functional testing and regression testing.

The web software is usually released by means of a model of software release known as alpha/beta testing.This is a simulated or actual operational test conducted by potential users or an independent test team at the developers’ site. This testing will be upon incomplete software and will be tested for small parts of the software.Alpha testing is often used for ready to use software as a type of in-house acceptance testing. Software that has been alpha tested cannot be released until all the major functional parts have been coded and tested.

After the alpha testing is completed the software is permitted to undergo the beta phase of testing. In beta testing the web software I completely built. The software is made available for use to a restricted number of customers intended for software testing previous to the official release. In case of website design it is easy to put together the various pages as the website design uses HTML. So the alpha/beta technique is generally not used for website development. This means they can build and test one page at a time. After completion they can move onto the next one, with each page independent of each other.

Code testing refers to the process where the testing or development engineer verifies the code and make sure that there are no software bugs. Because the time involved in web development is small it is important that the software is free of bugs. Paired-programming is one of the favourite methods that highly qualified testers can use to produce bug free coding.

Paired programming is a software development method in which two programmers work together at one keyboard. One programmer types in the code when the other person observes and reviews each line at the same time. This strategy is appealing because fewer bugs are produced. According to The Economist, “Laurie Williams of the University of Utah in Salt Lake City has shown that paired programmers are only 15% slower than two independent individual programmers, but produce 15% fewer bugs.”

The testing process continues through out the software development cycle so that at the time of final release it is free of bugs. Load testing is done to see at what point the application fails or the performance reduces when under heavy loads such as multiple users on or heavy server traffic. This type of testing will help to arrive at statistics such as how many users the site will sustain at the same time, the quantity of communication it will hold and the reaction time under various circumstances.

Compatibility testing evaluates the application’s compatibility with the computing environment like the operating system, database, browser compatibility, backwards compatibility, computing capacity of the hardware platform and compatibility of the peripherals.

The testing used to validate the conformance to specifications and requirements is the Functional testing. This testing involves performing a sequence of tests to validate the behavior of the software, feature by feature using a large number of normal and abnormal data. Regression testing is performed to ensure that enhancements, defect repairs or other changes to the software have not disrupted any existing functionality.

When interative methodology is used to develop software regression testing is crucial. In iterative programming, new modules are added to the core module to increase the functionality provided by the application, this needs to be done with the certainty that the added module does not affect the original functionality of the running module. All the types of test mentioned above are necessary to provide complete web software testing.

Which version of Excel?

As to the size of the class, somewhere between five and ten people can usually be accommodating in a training room with reasonable facilities. You will need to ensure that you have a conference or training room equipped with a computer for each delegate and a projector which can be connected to a computer used by the trainer to demonstrate each technique.

One feature that you should almost never omit in an Excel training course is formulas and functions. Functions are the lifeblood of Microsoft Excel. They allow the program to carry out complex calculations and produce useful results in a variety of different areas including statistics, engineering and the financial arena. Be sure to give the training company a good idea of the type of data your people work with and the information they need to obtain. This will enable the trainer to include coverage of functions which can help increase your productivity and get the most out of Excel.

Class sizes

Ideally, training courses should be attended by users with a similar level of experience and with similar requirements. If you have a mixture of skills levels, it is best to split the training into separate sessions to cater for people’s different needs. It is also important to limit attendance to those people who can attend for the entire duration of the training. Having delegates nip in and out of a training session is disruptive and doesn’t really benefit anyone.

If your staff are trained on an older version of Excel and then have their software upgraded to 2007, the differences are so significant that many of them will need retraining!
