Any kind of software testing which searches to discover new bugs or regressions in an ongoing program or application after amendments were made to it as a part of purposeful development or patch is known as Regression Testing in Software Development.

Regression testing concentrates on detecting flaws after changes are made to the main coding of software. It functions to reveal software failures as well expose old bugs that reappear.

Software regression takes place when the applications that were functioning properly suddenly stop its normal operation. Usually, such breakdown or regressions crop up uninvited when the existing programs are updated with newer versions.

The coding in the new version of the software fails to operate in the desired manner when it integrates with the previous version’s code.

General techniques of regression testing in software development comprises of repeating tests that were formerly performed on the software and observe to see if the software glitches that were resolved earlier have recurred.

The intensity of the testing is determined based on the stage of the software release and the risk involved in the updated features.

For example : to enable your Windows operating system to run smoothly and securely, Microsoft releases software patches to incorporate latest security updates, performance enhancement and feature enrichment.

 Such patches undergo extensive regression testing to check if the software operates efficiently in conjunction with all the software and hardware that are installed on windows.

This process holds true for all operating systems, software programs or applications and includes updating mobile phone firmware as well.   

In the business world, software regression testing has been conducted since a long time by a team of software quality assurance after the software developers finish their task of building the software.

The glitches detected during this phase involve lot of expenses. This issue is currently being attended to by the unit testing.

As a component of the development cycle, the developers write test cases however; these cases are usually unit tests or functional tests that authenticate the planned outcome only.

 The developer mainly concentrates on unit based testing and consists of positive as well as negative test cases. Functional tests are carried out on the entire program using numerous inputs whereas; unit tests are carried out on single functions.

Regression testing is performed not only to verify the precision of the program, but also to monitor the quality of its functionality.

For example, after creating compiler software, regression testing is done to check extent of the code, time taken for simulation and test suite cases.

The regression test suite covers three special modules of test cases:

a) A mock test of a replica of the actual software that has all the functions of the real software.

b) Further tests on the functioning of the software that can possibly be influenced by any alteration.

c) Tests that concentrates on the specific software sections that are modified.

Though regression tests can be executed via manual testing methods by employing software programming procedures, it is also performed by means of automated testing software or tools.

An automated test suite has a software tool that lets the testing mechanism to complete the regression testing in software development automatically.  

Programming projects are often connected to automate systems that run the regression tests after a specified period of time (daily, weekly, monthly and so on) and highlight software malfunctions.

Outsourcing software development is a good way to reduce costs and get the best quality IT software products. In the present economic downturn situation, it makes sense to use tools and techniques that are cost-effective.

The advantage with software development is that its development can be done in any part of the world. The end product can also be used anywhere. There is increased competition in the market, and only companies that can remain competitive can stay in the business.

This can be achieved easily if specialized works that require heavy investment are outsourced. There are various advantages to outsourcing the development of software.

• It Is Cost-Effective

Outsourcing software development proves a cheaper option compared to keeping a full-fledged development team in the organization.

Until a company is solely in the software development industry, it does not make sense to hire and keep many software developers on monthly salaries. Most likely, these software developers may be used only occasionally.

• Difficult To Find Qualified Professionals

It is also a fact that software developers are very costly to hire. Besides, a company may be situated in a location where there are very few software developers.

In such a case, it is more likely that the company has to pay higher than the industry standard salary if it wants to hire a software developer on a full-time basis.

• Allows You To Focus on Your Core Business

Business experts agree that for better profits a company must concentrate on its core business. If a company is not involved in software business then outsourcing software development is a better choice.

Such a company may not be able to utilize the team of software developers efficiently. Outsourcing allows the company to pay more attention to its core competency.

Nowadays, it is possible to monitor software development work in real time. There are various tools and techniques that can be used to monitor the work in progress at the company hired for software development.

What To Keep In Mind When Outsourcing

While outsourcing software development, there are some important things that must be remembered.

• Requirements

It is important to be sure about your requirements. This is the best way to avoid any confusion later on.

The software development company entrusted with the job must know every detail of the requirement. It is a good idea to prepare a draft and get opinions of employees who will be using the software.

• Check Credentials

Before selecting any particular software development company, it is important to check its credentials. It must have the required number of software professionals.

It must have handled similar jobs in the past and have some experience in the field of software development.

• Monitor Regularly

Just handing over the job and receiving the end product is not a good way to get the quality software. After assigning the task, it is necessary to monitor the progress of offshore software development regularly.

• Budget

Outsourcing software development is done to reduce the costs substantially. One way to achieve this goal is to do some cost-comparison of charges from different vendors.

There are thousands of software development companies. With a little research, it is possible to find the most affordable software development company.

Software development is a well-known process in the information and technology world; it ranges from building simple software such as those that are used by individuals, to highly sophisticated software built for large organizations.

In any of these cases, there is always a need to stay in control of any software developed by an individual or a company. This can be achieved through thorough tests and adequate supervision of software development projects, which in another way can be termed QA testing.

QA testing is basically a kind of test that gives details of a product to the consumers. In the development process of software, observations, corrections and some other forms of implementation factors are incorporated.

This must be duly documented and made known to those that will be making use of the development as it will enhance the integrity and the acceptability of the developed product.

So what is QA testing and why is it crucial to software development? Users of a particular software product measure the reliability and usability of the tool through the information provided by its developers.

These are some of the types of QA testing:

• Testing if a particular code that has been implemented to perform a particular function is working as expected.

• Checking for mistakes that might have been made by the developer or the programmer, by performing different kinds of usage operations and even sometimes trying to break the codes.

• Using the developed software in different environments, to certify its compatibility with any platform that prospective users might want to use.

• Subjecting the software to a lot of hands for testing, so that all can be able to analyze errors or bugs from different angles.

However, in performing some or all of these test operations there are some things that should be noted;

First, you need to understand that is better to make corrections on software when it has not been released to the public. This is because making corrections is cheaper and it reduces the chances of people losing confidence in the software.

Also, it enables the developers of software to be able to develop complex functionalities and take note of those that will be developed and added as updates. There are experts available when it comes to software testing as these people have taken it on as a profession.

People in this category, also known as Software Testers, should be hired when there is a need to test software. From their wealth of experience, they know the specific and common things to test for in any development.

Another way of finalizing tests is to release a test-version of the development for few people in the target market to use and give feedback as regards the product.

In conclusion, this can be grouped into two modes of testing in software development, testing from the point of view of the developer and from the point of view of the users.

The purpose of software testing is to ensure that the software performs as it should.

There was a recent announcement that the Duqu virus was using a flaw in Windows operating system to infect computers. This is an example of a software defect that was not uncovered in testing and which could have serious implications for users.

It is ultimately the users of software who benefit from thorough testing. The following areas are potential sources of problems:

• The individual programs may not be operating correctly
• The combination of several programs may not be performing as required.
• The programs may be performing correctly to specification but may not meet the actual user requirements in operation – the specification is flawed.
• The system may be performing correctly as designed, but the design may be problematic, as in the Duqu virus example mentioned above

For proper testing, the tests should be designed in tandem with the software. Tests should actually be set up before the programs are written to encourage thorough testing. The following types of tests should be done:

• Unit testing – In unit testing the individual programs are tested. To simplify this, programs should be specified to perform only one task. This makes the testing simpler because the number of interactions is limited
• The units which form parts of sub-systems should be tested in combination to make sure that they are performing correctly.
• The whole system should be tested to make sure it is functioning to specification.
• The software should be tested to be sure it can be implemented correctly.
• User testing by a knowledgeable user is needed to make sure the system as designed will meet the user needs correctly.

A knowledgeable user should preferably be available at all stages of testing to help make sure that the software, while performing correctly to design, will also meet the actual requirements in practice and that important functionality has not been overlooked in the design process.

The users involved in testing should preferably be those who actually currently perform the tasks. More senior people may not be aware of all the detail involved in performing a task.

Traditionally, a testing team only got involved in system acceptance testing, but it is better if they are engaged at every stage. The earlier a fault, particularly a design fault, is picked up, the less it costs to correct and the shorter the delay.

Automatic testing tools which are available are a very useful adjunct, as well as different testing methodologies, each of which has its own advantages.

These help to pick simple programming errors and technical mistakes. But ultimately there is no substitute for the educated eye of an experienced user for ensuring correct functioning and design.

White box testing will report on the code usage in each Black-box test, and whether all the code has been tested. Without this it is difficult to ensure that everything has been tested and that every possible combination has been covered.

In practice, an unexpected combination which rarely occurs can be the agent that reveals a programming flaw, and these may go undetected and compromise the data.

To many people it may seem that testing is an expensive process and there is often a temptation to reduce the amount of testing due to budgetary constraints. This is a basic mistake which can compromise the success of the project.

It is better to limit functionality or reduce “bells and whistles” if the budget is tight, but not testing. Thorough testing is the best way of making sure that a quality system is produced, and this should be the primary concern.

Mobile applications are increasingly being recognized by marketers as pretty powerful tools to help solidify relationships with customers and create very loyal followers in the process.

It is however important to realize that mobile applications development is not as easy as it may sound and it requires special skills and a deep understanding of exactly how it works best for your interests in reaching out to your customers.

To start with it is important to recognize the unique advantages that mobile phone applications bring to the table. People usually carry their mobile phones wherever they go.

What this means is that as a business you can get immediate access to your market and customers. What’s more is that most people will access and read messages received on their mobile devices.

This is very different from web messages where it is becoming an increasing challenge to get even a small percentage of the folks who receive the message to actually open it.

The most effective way to use mobile phone applications to create loyal customers is to offer additional useful services usually for free. It should be the kind of service that will always help your customers remember you and your main line of paid products and services.

This is important in a world that is increasingly crowded by too many advertising messages all competing for our attention at the same time. Ads are hurled at the consumer every waking moment from so many different mediums and outlets.

People (read, your customers) now tend to shut out most of these messages and the result is that advertising is much less effective than what it used to be. With mobile applications development you have a unique opportunity to reach and engage folks who are increasingly shutting out the advertising “noise” that is now everywhere around them.

The big challenge is getting a large chunk of your audience to opt in to your mobile phone application because it is all permission based and you do not want to ruin the reputation of your brand by intruding on people with services and messages that they have not requested.

However if you have a useful application this should not be too difficult. You can use additional features like making it possible for the users of your application to personalize it for their specific and individual needs. This has been proven to turn many applications into highly sought-after mobile services.

It is well worth your time to take the extra trouble of ensuring that your mobile application is highly desirable to customers because the reality is that there are plenty of others competing for the attention of your prospects out there.

One of the things you can do is to ensure that you have a rich, loaded interface. Pay attention to the little but important details like taking full advantage of the phone functions like touch screen features which are usually a big hit with phone users.

If it is something that your users will enjoy and want to keep using then you have a hit and an amazing communication channel to keep on talking to your prospects directly.

This way you can ensure that they remain loyal because they are continuously reminded of you in a way that they do not find annoying or intrusive. That is the real power of mobile applications in helping you create loyal customers.
