Application development is essential for any organization to tap into the growing market as well as popularity. But it is just not enough to build up an app; it is just the beginning or rather the easy part. The app must be tested for user experience issues as well as bugs. For measuring those factors, certain metrics are essential. These metrics are known as KPIs or Key Performance Indicators which may differ for each organization. These factors help determine the success of an application. With so many mediums available, it may be hard to select the apt KPIs; to make the job easier, here are some common must-have KPIs that an organization should use almost compulsorily. Continue reading KPI to decide the success of an application
When it comes to development as well as designing of web pages, the first and foremost factor that the designers and developers keep in mind is – accessibility. This is the most, if not the only fundamental objective behind designing web pages. When we mention the term, ‘accessibility’, this literally means making a particular site available or visible to anyone trying to look for the site to get information about any product or service. In simple terms the word, ‘accessibility’ means making the pages ‘public’. Now, the issue is not as simple as it looks. The main reason behind making the web pages accessible is not just making it available to anyone, but a combination of a number of other factors. Let us discuss the three most important reasons behind making the pages accessible. Continue reading Top 3 reasons to make websites accessible
When we speak about programming languages, newer types with more value added features are being innovated or structured every now and then. All these languages are bringing in a revolution in the software world. Amongst an appreciable number of software programming languages that are being adored all over the world, let us discuss top 10, which are making news in 2014.
It is another intermediate level platform that comes up with various object oriented features that are originally designed to enhance the functionality of C. C++ helps major software packages like Adobe, Winamp, FireFox and so on. C++ is generally utilized for developing system, software applications, client applications, high-end server, video games etc.
3. Objective C
This is another general purpose language that is object oriented and is used for Apple OS. It also powers APIs as well as Apple’s OS X, iOS. Besides, it is also capable of creating various apps for iPhone.
PHP or HyperText Processor is a server side, open source scripting language that is specifically designed for the dynamic websites as well as development apps. The language comes up with properties that help it to be directly embedded into HTML source documents instead of any external file and this has made the language immensely popular for the web developers. It is one of the most popular languages that are applied to develop sites like Facebook, WordPress, Digg and so on.
It is another highly popular concurrent, general-purpose as well as garbage collection language as well as runtime system. The sequential subset of this language comes up with capabilities to help in the evaluation, dynamic typing, and single assignment. The language has value added features like hot swapping, so that the codes can well be changed during run time, without stopping a particular system.
This is one of the most widely applied and popular scripting languages for server-sides that are specifically designed to be used in mobile apps as well as various websites. It is considered one of the easier languages that the beginners find fairly handy to use, much due to its readability along with its compact syntax. This implies that the developers will have the option of using fewer codes than other similar types of languages for expressing a particular concept.
This is one of the most famous client side as well as server-side scripting languages that is developed to be used across various web browsers and is considered essential for development of different interactive as well as animated web functions. The language can also be used for developing games and for writing desktop applications.
Ruby is a dynamic, scripting platform that is object-oriented and is used to develop websites along with mobile apps. Basically, this platform has been designed in a simplistic way, mainly to power ROR or Ruby on Rails, which is used on Shopify, Scribd, Groupon, and GitHub. The language is considered extremely user-friendly and easy, especially for the beginners.
SQL or Structured Query Language is a specially designed platform that is used to manage data in various RDBMSs or Relational Database Management Systems. It is most extensively used to utilize its unique “Query” function that searches various informational Databases.
This is a standardized as well as a general purpose programming platform that is purely functional. It comes up with a number of non-strict semantics as well as strong static typing. It can also be used as a functional programming platform, where ‘function’ is used as the primary control construct.

There are a lot of software development companies in the market. Each of them claims to be the best in the business. From one point of view, it will give a lot of options to choose from. However, from the other it may well leave a customer bedazzled at the end of the day. The customer, as a result may end up choosing a company which is not enough experienced to meet the requirements. Again, it may so happen that the customer selects a company that will charge an exorbitant price that will overshoot the budget by a substantial extent. Hence, it is imperative to select and adopt a definite way, when it comes to looking for the right software development company.
Experts are of the opinion that it is not right to put emphasis solely on the price of services. It is because there are a lot of companies that will promise to deliver service in shoestring budget. However, the quality of most of these ‘so called cheap’ services will be far from the expectation. Hence, what is needed is a right balance between the quality and price. In fact, it is imperative to give more emphasis on quality than price. However, when we speak of quality, there are certain factors that are needed to be focused on, before entrusting the responsibility. Let us discuss them in details.
While putting more emphasis on the quality instead of price, the following aspects are to be taken into account.
First of all, it is crucial to make sure the developers associated with the service provider have a wide range of customers from various niches of industries. This will imply that the service provider has a wide range of experience. It is because the more experience the software developers will have across a wide range of businesses, the better will be their probability of providing higher quality services.
In this respect, it is important to guarantee that the company has the experience of using various types of technologies. It is definitely better to opt for the firms that have the experience of creating projects in Java, .Net, PHP, C++ for different platforms like web, iPhone, and desktops. In case someone is willing to opt for an organization that will be able to take up the responsibility of an application development, the customer should not opt for firms who have experience on solely that particular technology. Always, companies with a wide range of experience across various platforms or technologies should get preference.
Never opt for big or expensive names. These big names may have a pool of highly talented or experienced developers and technicians, but there is no assurance that your project will reach their desks. It may well be that your requirements will be taken care of by developers who are less talented and even fresher. These big shots will charge exorbitant amounts more because of their reputation and value of their brand name than the quality of work they will deliver. Frankly speaking, at the end of the day it may drill a deep hole in your purse while you do not get what you pay for.
It is better to invest money for companies that mainly use offshore labor. This means, these companies do not rely solely on experts and developers from the developed countries. When that happens, the cost automatically shoots up because of the high labor cost these countries charge. It is better to opt for companies that hire labors from the developing, yet technologically sound countries which charge much lower labor cost.
Companies that deliver quality service will not deliver the entire project once and for all. They will, instead, prefer small and frequent releases in installments. This makes your understanding easier and it can be made surely that the product that is being delivered is entirely glitch free. Besides, it also makes deployment much easier.
Do not opt for companies that have just a few developers. Solid teams that will be delivering the project in time are ideal as that will help in controlling the costs. Experts are of the belief that one should vouch for companies which are home to at least 3 to 4 times more technicians and developers than what is needed to complete the project on time.
A quality software developing firm must have an online tool that will help track and trace the progress of the development. The tool should come in handy when taking care of bugs or features, and will also help in keeping a track of the developers’ working hours or daily notes that is left on an hourly or day to day basis. The company should also make every document available online, including the agreements and the terms & conditions thereof, various invoices, payment details etc.
When it comes to agreements, firms that give the ownership are preferable. The company needs to hand over the resulting source codes and other inventions that come up out of the development.
When you are offering the responsibility of software development to a firm, you better put more emphasis on quality instead of price for it is quality that will make the difference at the end of the day. Again, when you are focusing on quality, all the factors will have to be taken into account to make sure that the software developing company is competent enough to provide you the quality service that you are eyeing for.

Five Essential Elements of the Web Components
Similar to other software development projects, website development also needs a solid blueprint. The web components provide the blueprint for a project through the tag. The tag enables programmers to store specific markup on the page that can be reused and cloned subsequently. The developers familiar with handlebars, moustaches and similar libraries can understand and use the tag immediately. As the markup inside a template are not recognized by web browsers, it becomes easier to include non-executable tags for images, videos and audio having external sources.
Unlike other web components, decorators are yet to have a specification. The decorator components can, however, be used in a number of ways. Normally, decorators complement the rich visual and behavioral changes by applying templates. In addition to overriding and enhancing the way existing elements are presented, the programmers also have option to use CSS to customize the decorators. Thus, each user can define his own decorator simply by using a markup and a scripting language.
3) Custom Elements
The custom elements can be defined as advanced DOM elements that can be defined by programmers. However, the custom elements, unlike decorators, are both ephemeral and stateless. So the programmers can use custom elements to encapsulate state, along with providing script interfaces. However, each author must understand some of the important differences between custom elements and decorators. A custom element can be defined through the < element > tag.
4) Shadow DOM
Most web developers use iframes to ensure that the user experience is not affected negatively due to HTML and CSS. Despite being useful, iframes cannot be used for building complex and large internet applications. As an innovative web component, Shadow DOM enables programmers to avail the features and advantages of iframes including style and markup encapsulation. The developers can further use Shadow DOM to strictly control the interaction between content and styles. The programmers can crate Shadow DOM simply by selecting an element, and then invoking its createShadowRoot method. The action will return a document fragment that can be filled with desired content.
Both custom elements and decorators can also be loaded from external sources. The < link > tag is used to define if the custom element or decorator will be loaded from external sources, along with the URL of the external file. The user agent can further interpret the decorators and custom elements. But the import property of the < link > tag will help the scrip in accessing the DOM. Further, programmers are required to use the CORs attribute to describe if the definitions are designed to run across multiple websites and internet applications.

The Agile testing approach emphasizes on agility and speed. The development process runs concurrently along with the evaluation process. Testers have to work often as well as fast since the development model is time-boxed. The testing of the code has to be done very frequently, in fact in some cases almost daily. This makes Agile testing quite challenging, more so in comparison to evaluation of traditional development methods. If not handled properly there is a risk involved of Agile testing becoming uncontrolled, chaotic and unstructured. But when automation and agile testing are implemented together, it is possible to overcome those challenges.
Inadequate test coverage
This can be hugely problematic; with Agile, there is an increase in volumes of tests. Due to that, often for every user story, too little results of tests are written down which leads to lack of visibility into codes changed all of a sudden. Sometimes developers change codes that are beyond the scopes of released features which are done for many reasons. To tackle this challenge tests should be linked to user stories which will provide insights into test coverage.
It is not always very easy to take care of deadlines; there are times when we have very little time for testing at a cycle’s end. Long evenings along with proper documentation will help in that case. However, it may be challenging since testers are required by Agile to work by deadlines each day. So make everything work, the automation of most tasks must be done well.
Codes broken accidentally because of frequent builds
If daily builds are performed, there always remains a risk of breaking the existing code. When sole reliance is on manual testings, full regression of the existing code every day is not practical. So the best bet is to use automated evaluation tools for recoding and running of tests automatically. This will ensure the testing of more stable features without new code breaking into them.
Detection of defects
It is very important to detect defects early on during the development cycle; being late will need more money and time for the fixing process. In fact, if the defects could not be found till the production, it will prove to be a bigger problem altogether. Implementing peer reviews along with using of static analysis tools for scanning of code for identification of defects early on, can help in this respect.
Ignoring traditional evaluation techniques
As the movement of agile testing is faster, the coping of the flowing development stream is very challenging for testers. So it is best to adopt a streamlined as well as proper approach. For that you should not be just dependent on documents but you should constantly keep interactions with stakeholders, developers, end users and clients.
Detection as well as fixing of bugs
The main aim of this testing is detection and getting rid of major bugs during the very initial stages. It is very expensive to fix bugs during the later stages of development cycle. In fact, despite identifying the bugs, fixing within the specific time-frame may be extremely challenging. This can be resolved by running static analysis tools over source codes. Automated tools can also be used for detection of hidden bugs.
Bad API Testing
The best coding skills are not necessarily inherited by testers. These days, the APIs are revealed by most software so that it can be easily used by other developers for integration along with other uses. If this area sees any mistakes the application or software’s popularity will be seriously crippled. Using API testing tools that are automated will give Agile testers an edge to tackle API evaluation.
According to the points discussed here, agile approach needs to be dealt with accuracy as well as speed. Manual testing is not a process that can be relied upon solely. Efficient automation will make the testing processes better and faster. Thus automation has to be implemented during all levels so that you can ensure all angles. Independent software testing companies can help immensely in this regard.
