105 Types of Software Testing Every Tester Should Know

Listen on the go!

Due to businesses embracing digital platforms, mobile, big-data, social media, cloud and the internet of things, there has been a definite rise in software services. With agile methodology, testing is introduced earlier on in the software lifecycle.

  • The past few years have witnessed an exponential growth in the number and variety of consumer and enterprise mobile applications, and this shift to a mobile platform in every industry is expected to re-engineer businesses for mobile responsiveness.
  • Real-time scalability challenges, instant data collection and deployment, and an increasing need for live integration of information, are some of the needs and challenges that make it imperative for Big Data applications to be tested thoroughly. Cigniti leverages its experience of having tested large scale data warehousing and business intelligence applications to offer a host of Big Data Testing services and solutions.
  • Over the last decade, how internet is being leveraged and used has undergone a major shift with the advent of Smart Phones and Tablet Computers. This shift has caused a “Big Transformation” in the e-commerce industry, as it has dramatically changed consumer behavior and moved them away from transacting traditionally. Consumer base and expectations have grown manifold. Consumers expect e-commerce platforms to be smarter, faster, and more secure.

In this post, we address the various types of software testing. Software testing is of different types, and they are all performed in order to achieve different objectives when testing a software application. It is a general misconception that software testing is usually only performed by specialized testing teams. While this holds true for almost all cases of testing, there are still significant types of testing that end-users, developers, and specially configured systems in certain organizations would need to perform. The well-known list of 105 types of testing has been categorically split according to the teams in charge of conducting those types of software testing.
