All of us have had the frustrating experience of downloading a mobile app only to find it disappointing in terms of functionality and speed. Therefore, mobile applications need to be tested to ensure they are free from bugs that curtail their usability, functionality, and consistency.
Usability test cases include ensuring that keyboard input be minimized as far as possible and text is kept simple and visible to the users. The user needs to be prompted when trying to download a large amount of data which is not compatible with the application performance. Some of the functional test cases include ensuring that the app gets minimized in the case of an incoming phone call and allows social networking options such as sharing, posting, navigating etc.
The application should display relevant error messages to the user in case of an error. The application needs to work in all versions be it 2G, 3G or 4G. Since mobiles come in different screen resolutions, build and hardware, compatibility testing needs to be done to ensure the application performs well across different types of mobiles.
In the digital age, your organization has to provide a seamless customer experience, worker experience, and partner/supplier experience. Digital assurance and testing services facilitate the smooth integration of the various digital functions for fast and efficient business outcomes.
Digital assurance involves testing across the entire digital ecosystem of a business - cloud, mobility, connected devices and big data down to specific elements like web portals, web content, web analytics and digital marketing. Automation and virtualization strategies can be deployed to ensure faster time to market.
To arrive at the optimal assurance strategy, social analytics and defect analytics can be deployed. Performance related issues should not only be checked from the server side, but also from the front end. The digital infrastructure is also tested to ensure it is resilient to security vulnerabilities.
Large datasets that are versatile in volume, variety, and velocity have to be tested for their quality of data processing. Big Data & Analytics Testing is done to validate structured and unstructured data for conformity, consistency, accuracy, and data completeness.
Since big data refers to large data sets that cannot be processed using large datasets, Big data testing is more about verifying the data processing than testing individual features of the software. First, data from RDBMS, social media, blogs, weblogs etc. should be validated to ensure that correct data is being used. This is followed by MapReduce validation and output validation phases.
The test environment should have adequate space to store and process large amounts of data. To maintain high performance, it should have minimum requirements for CPU and memory utilization. It should be characterized by distributed nodes and data. Performance testing for big data includes data throughput, data processing, and sub-component performance. Architecture testing is another critical aspect of big data testing as a poorly designed system can lead to performance degradation.
E-Commerce sites are highly dynamic in nature. The traffic keeps fluctuating and can get very high at certain times, offers and discounts keep changing, new products keep pouring in, customer identity has to be protected - to name a few challenges.
E-commerce sites, therefore, have to be tested for their ability to handle dynamic load conditions and prevent identity theft of customers to deliver a smooth shopping experience for the customer. Various aspects like hero image, search, product details page, shopping cart payments, recommendations, categories and after order tests have to be taken care of.
Testing of every link in the homepage using HTTP status code has to be done before regression testing as the links keep increasing or changing. Regression testing of the site should be performed to keep pace with the frequent changes to the site. As far as security testing for e-commerce websites is concerned, Data confidentiality, DENIAL OF SERVICE ATTACK, content security, User Account security, credit card security has to be taken care of.
