API: Concept and Testing – As we know, API testing is a type of testing a software that is performed as a part of integration testing to determine if they meet our expectations for functionality, reliability, performance, and security.

In order to discuss API and Web services testing, we need to first identify what is an API and how it works. An application programming interface, or API, works to connect an application to the web and to other APIs.

API testing is used to determine whether APIs return the correct response for a broad range of feasible requests, react properly to the cases such as failures and unexpected/extreme inputs, deliver responses in an acceptable amount of time etc.

WHY IS API TESTING IMPORTANT?

API testing is one of the most challenging parts of the whole chain of software testing and QA testing because it works to assure that our digital lives run in an increasingly seamless and efficient manner. While developers tend to test only the functionalities they are working on, testers are in charge of testing both individual functionalities and a chain of functionalities, discovering how they work together from end to end.

The first part of API testing involves setting up a testing environment, with the required set of parameters around the API. This involves configuring the database and server for the application’s requirements. Once you’ve set up your API testing environment, make an API call right away to make sure nothing is broken before you go forward to start your more thorough testing.

COMMON KINDS OF API TESTING

Of course, automated API testing can be performed in many conditions, particularly when you are pressed for time, making it compelling when you are following continuous software development release cycles.

However, in certain situations, like where APIs are connecting the Internet, it’s nearly impossible to perform only testing automation. Therefore, it’s good to automate if the API calls are giving back the correct responses.

THUMB RULES TO FOLLOW

Now it’s good to have a list of rules of thumb to follow in order to help make the test as successful as possible.

Happy Testing!

Many companies are entering this market, but due to the high level of competition, they aren’t capable of making an impact. One of the mistakes that many of these companies are making is not investing in their digital marketing efforts to support the overall marketing objective.

4. SEARCH (SEO)

Did you know that 77% of online health seekers say they begin their session at a search engine? An essential part of your digital marketing strategy, whether you’re a medical device company or not, is to search for keywords and phrases that individuals might use to find your medical device.

If your company does not appear in the search results, you should invest in SEO measures and online advertising to start increasing your brand exposure. Furthermore, these keywords are the gateway to reaching your potential customers from all around the world.

5. SOCIAL MEDIA

The most effective form of word of mouth is happening online. Now with social media, consumers utilize these channels to express their opinions, learn about new products, and engage with brands and key influences.

As a medical device company, you must ensure that you are also active on these channels and use social listening tools to be aware of what consumers are talking about in order to address their needs directly and keep track of your brand image.

In addition, your social media presence can be targeted toward building relationships with key industry influences in order to reach a wider audience and generate leads. Overall, “54% of B2B marketers said they have generated leads from social media” (SMO).

6. PAID ADS

A digital marketing strategy is incomplete without the investment in paid ads. In today’s competitive landscape, visibility is key. You cannot expect customers to flock to your website as soon as your product is released. Organic search is very valuable but paid advertisements, such as Google Adwords and display ads, is crucial in gaining exposure in search results.

Here are 5 reasons why you should invest in paid ads:

7. LEAD MANAGEMENT

The overall objective of all your digital marketing efforts is to generate leads. It is your responsibility to be able to effectively manage these leads, nurture them with the appropriate content, and eventually turn them into customers.

“79% of marketing leads never convert into sales. Lack of lead nurturing is the common cause of this poor performance.” Do you have a lead nurturing strategy in place? Are you sending marketing qualified leads to your sales teams?

8. MARKETING AUTOMATION

“80% of marketing automation users saw their number of leads increase, and 77% saw the number of conversions increase” VB Insight. Generating leads has no value if your company is not following up on them and nurturing them properly.

One of the key advantages of utilizing a marketing automation system is the fact that it is customizable based on your various targets, sales cycles, promotions, or any other strategic plan. Hence, this process makes it much easier to monitor leads as they move through the sales cycle. Therefore, you can maximize the potential of every active lead that enters that cycle.

9. WEBINARS

Integrating webinars in your digital marketing strategy is key to positioning your company as a thought leader in your industry. Especially in the ever-changing medical device market, it is crucial to continually educate consumers and individuals in the industry to build trust, increase web traffic and brand awareness, and generate leads. Webinars can also be re-purposed for multiple campaigns. Therefore, Webinars is one of the Significant Components of Digital Marketing.

10. VIDEOS

By implementing video in your digital marketing strategy, you create engaging content that consumers can easily view and share. Based on recent research, “64% of website visitors are more likely to buy a product after watching a video”. Therefore, every medical device company should take advantage of this video marketing trend and create original video campaigns that present the company’s values, product features, and the lucrative benefits to the consumer.

As per our experience, Videos are the most effective Significant Components of Digital Marketing.

11. ANALYTICS

One of the most valuable elements of having a digital marketing strategy is the fact that you can continually monitor the outcomes and be able to optimize your strategy with each campaign iteration. There are several analytics tools that will assist you in tracking the progress of your marketing efforts in order to be able to analyze and adapt over time. This availability of data is key to maximizing your return on investment.

12. SALES TOOLS

Every company, especially one in the medical device industry, requires an active sales force. However, this sales force is ineffective without the right set of sales tools. Your salespeople are your army and you must be able to provide them with the proper ammunition in order to increase your chances of winning in this competitive landscape.

As part of your digital marketing strategy, it is essential to invest in a robust set of sales tools, such as brochures, sales presentations, mobile sales app, and a sales deck, in order to empower your sales force and increase the success rate of your campaigns.

We are now living in the digital age. Therefore, traditional marketing alone won’t result in the profits you’re looking for. Marketing in digital channels is a requirement. So there is no way around it. Just like you devoted a lot of your time and energy into developing your product, it is essential to invest in a comprehensive digital strategy to introduce your product to your targeted markets and continually manage your brand presence.

Ensure that you measure your actions so you understand your digital footprint and whether you are maximizing the potential of your marketing campaign. When done effectively, this can set you apart from your competitors and lead to sustainable success for your medical device product.

It has always been a confusing part for almost every client to choose in between AngularJS and NodeJSfor their web applications development. Moreover, we have come across a number of clients who wanted us to suggest which technology to use for building server side and client side web applications. However, understanding the difference in between AngularJS and NodeJSis must before you pick any of them for your server side and client side Web Application.

Primarily, AngularJS Development and NodeJS Development both are JavaScript frameworks used to develop web applications. Initially JavaScript was used for simple things like Validation of form data, Image zooming on hover of thumbnail, animating html elements and others.

However, from last few years, JavaScript emerged largely and it has become a powerful programming language to create optimised server side and client side web applications.

NODEJS

NodeJS is written in C, C++ and JavaScript languages to interact with server-side and create smooth and powerful web applications. Moreover, it is a cross-platform runtime environment for web applications. It uses V8 JavaScript engine to execute JavaScript code. It’s similar to JRE (Java Runtime Environment), Adobe AIR, CLR (Common Language Runtime), ART (Android Runtime) or Action Script.

It is widely used for creating server-side Real-time web applications.

ANGULARJS

AngularJS by Google is also JavaScript framework but it has unique syntax and tag attributes. Moreover, it is MVC based architecture. Furthermore, AngularJS makes use of custom HTML tags and HTML tags attributes (directives). Although it is written in JavaScript, it is completely different than other JavaScript library like jQuery.

AngularJS is widely used to create powerful single page client-side web application. If you are looking to Hire AngularJS Developer, please get in touch with us.

In conclusion, NodeJS is runtime environment useful to develop server-side web applications while AngularJS is useful to develop single page or multi-page client side web applications.

AngularJS-Vs-NodeJs-Compatibility-Applications-Uses

COMPATIBILITY

You must install NodeJS in order to write web application using NodeJS. It can be easily installed in Windows, MacOS and Linux. On the other hand, AngularJS does not need to be installed. Moreover, you just need to add core library files of AngularJS in order to develop your first web application using AngularJS. AngularJS is compatible with all modern web and mobile browsers.

APPLICATIONS AND USES

NodeJS

NodeJS is an event-driven architecture which is useful in creating real-time web applications like Chat apps. It also supports non-blocking input-output I/O and has built-in core modules. One of them is the HTTP module which is used to create web server in your NodeJS web application.

Moreover, there are many other frameworks built using NodeJS (express.js, meteor, geddyjs, mojito, sails.js, partial.js etc). These additional frameworks with a built-in set of features help you to write powerful, fast and scalable server-side web applications.

AngularJS

AngularJS allows you to create MVC pattern with two way data binding. Two way data binding means, changes in model are propagated to view and changes in view are reflected in model. It makes your client-side web application more powerful. AngularJS is more popular to create single page client-side web applications.

In conclusion, both are open sources and powerful to their own features. You can derive your web application requirement and choose the one accordingly. NodeJS is used to build real time server side web applications while AngularJS is more suitable for creating single page client side web applications.

Amazon Web Services (AWS) is a secure cloud services platform, offering computing power, database storage, content delivery. These help your businesses to scale and grow. Talking about AWS History and Benefits, AWS started offering services in 2006. Explore how millions of customers are currently leveraging AWS cloud products and solutions to build sophisticated applications with increased flexibility, scalability and reliability.

AWS HISTORY AND BENEFITS

For AWS History and Benefits, let’s start with the AWS history first. Next part will be all about most important AWS benefits.

First of all, Amazon Web Services (AWS) began offering IT infrastructure services to businesses in the form of web services in 2006 — now commonly known as cloud computing. One of the key benefits of cloud computing is the opportunity to replace up-front capital infrastructure expenses with low variable costs that scale with your business.

With the Cloud, businesses no longer need to plan for and procure servers and other IT infrastructure weeks or months in advance. Instead, they can instantly spin up hundreds or thousands of servers in minutes and deliver results faster.

2003

In late 2003, Chris Pinkham and Benjamin Black presented a paper describing a vision for Amazon’s retail computing infrastructure. Furthermore, it was completely standardized, automated and would rely extensively on web services for services such as storage, drawing on internal work already underway.

Near the end, they mentioned the possibility of selling virtual servers as a service. With this proposal, the company could generate revenue from the new infrastructure investment. They launched their first AWS service for public usage in November 2004 which was Simple Queue Service.

We can’t skip mentioning Chris Brown when we talk about AWS History and Benefits. Yes, Amazon EC2! Amazon EC2 was built by a team in Cape Town, South Africa, under Pinkham and lead developer Chris Brown.

2007

In June 2007, Amazon claimed that more than 180,000 developers had signed up to use Amazon Web Services. If you are looking to Hire AWS Developer, you can checkout our services. We have an expert pool of AWS developers.

UI elements and content play an important role in the success of any eCommerce website and hence, you should actively get involved in ensuring the correctness of UI elements and content.

Think about your own user experience when you visit a website: Are you more likely to purchase if you can easily find what you’re looking for or if you have to click through 50 options?

One of the best and most proven ways to test is something called A/B testing. A/B testing is comparing two versions of a web page to see which one performs better. You compare two web pages by showing the two variants.

5. MOBILE RESPONSIVENESS

The website should respond properly to devices on which it is displayed and this is why testing mobile responsiveness is an essential part of the process.

If you wish your website to be used by visitors viewing it on their Smartphone or tablet then you also need to test all of the functionality on each of the following mobile devices.

Many of the browser testing tools can help with mobile websites like Appium, AppAssist, fast lane etc.

6. SECURE PAYMENTS & CUSTOMER INFORMATION

Payments are an essential part of testing eCommerce websites. After all, this is what allows users to purchase for their items without the need to call a number to place their order.

eCommerce business owners also have to ensure that all the payment and sensitive information regarding customers are completely secured at all times like all the payments are processed via servers that are SSL encrypted.

Different payment types should all be tested, e.g. Credit Card, PayPal, Bank Transfers, Installments, etc.

7. TESTING : KEEP IT REAL

It is advisable to test your eCommerce store in the real-world scenarios. However, the production environment is always different in terms of infrastructure, software configurations, shared networks and links. This is the reason the impact of the application is different in a real environment and devices than lab environment.

Lastly, acknowledge that continuous testing and monitoring is essential to make your e-commerce site grow Faster. Hope this helps and happy testing.

From the shocking launch of a new language to prominent similarities with other languages, it has been just 3 years and still, it looks like Swift has come a long way! Swift is getting popular each and every day. Any good iOS Swift developer hoping to start new iOS project would choose nothing but Swift language to begin with.

IOS SWIFT DEVELOPER

In order to save your time and make the transition easier and interesting, we have prepared a list of libraries that according to us every iOS Swift developer must know. If you are looking to hire iOS App Developer, get in touch with us.

1.) ALAMOFIRE

Almost every application nowadays deals with web service calls. API integration is the base for almost every application in today’s era. Alamofire is an HTTP networking library built on top of NSURLSession and the Foundation URL loading system. Alamofire comes to the great rescue when one wants to abstract away and simplify networking in the application.

2.) SWIFTYJSON

Well, the API integration part is done and one feels like that is it! Now only part left is to manage JSON and use the data from it. Is it that easy as it sounds? well, you’ll know! And then what saves us from handling explicit data types that cause bugs and crashes is SwiftyJSON. It really deals with JSON in a well readable way which handles options unwrapping automatically for us.

3.) OBJECTMAPPER

So, We made a successful call attempt to APIs and managed well to receive but what next?! Fetching data by mapping resource is another tedious job to handle. ObjectMapper helps us convert JSON into a model object and not just that but vice versa too! It supports nested object pretty well too.

4.) EUREKA

And when you just thought your job is easier, one more challenge arises when you have to display all the fetched data into table views. Not really difficult but boring to very high extent as it is one of the most used element. In order to spice it up, Eureka helps you write them in a simple and elegant way. It consists of rows, sections, and forms. It really saves abundant time especially when your application contains a plethora of forms.

5.) QUICK

A behavior drove development framework not just for Swift but for Objective-C too which is inspired by RSpec, Spectra and Ginkgo. One of the major benefits of using Quick is that it comes with Nimble which is a matcher framework for tests.

6.) SNAPKIT

Another latest approach to set UI for application is using Auto Layout. SnapKit is an Auto Layout library that simplifies coding for the same requiring nothing but just a minimal code that too without losing readability. It is type safe which comes at rescue in order to get rid of programming errors.

7.) RXSWIFT

RxSwift is nothing but the swift version of Rx and serves the same goal as to enable easy composition of asynchronous operations and event/data streams. Consequently, RxSwift is a framework for functional reactive programming.

8.) SPRING

Spring is an animation library. Be it inside of storyboard’s runtime attribute or through code, Spring helps one both ways to set an animation to an object. It supports number of already written animations, transitions and properties.

9.) CORESTORE

The main motive of CoreStore is to provide type safe and elegant interaction with Core Data. It is a wrapper library that provides APIs for all common methods to effectively interact with database.

10.) KINGFISHER

Kingfisher helps us download and cache images from the web. It does that all asynchronously. It caches downloaded images both in memory as well as disk in order to improve application experience to all new level.

What are your thoughts on the same, people? Do you know some library that deserves the place in this list? Please leave a comment and let us know.
