WHAT IS SOFTWARE TESTING?

Posted by Atul on July 21st, 2018

Software testing is basically an inspection of the software directed to furnish the investors with information about the idea of the product that is under scrutiny. It is a test that checks the execution of an application for the purpose of finding bugs in the software. It can also be thought of as a process to verify whether the programmed application meets expectations, both business and technical. That means that this is a means to ensure that the product works as expected. It includes the execution of a product segment or framework part to assess at least one property of interest. 

The extent to which a product is put under test is characterized by the following properties:

• Fulfils requirements that guide its development
• Processes all types of inputs correctly
• Executes within the provided time limit
• Portability and installation hassles
• Provides the desired outcome

Since the probability of tests for simple software components is infinite, we require some strategy to pick a test that works effectively for the required job with the provided time and resources. That is why software testing is basically a try to run a program meaning to find bugs. This process is iterative, i.e., it runs in a loop, because if one bug is fixed it can lead to many other more complex bugs.

The main reason to test is to find out software shortcomings so that they can be fixed. Testing cannot guarantee that the function works under all conditions; it can only prove that it cannot work properly under certain conditions.

There are various methods to accomplish testing of software. Static and dynamic testing are two such methods. Static testing involves proofreading and checks syntax and data flow whereas dynamic testing involves running of the program itself.  A different way to test is the box approach. The box approach involves white box testing and black box testing. The former checks the internal workings of a code where the latter examines the functionality without taking in any internal implementation. Grey box testing includes knowledge about internal information and calculations for reasons to outline tests while executing those tests at the client, or black-box level. Apart from these, testing can be labelled under the following group: installation, compatibility, smoke and sanity, acceptance, alpha, beta, continuous, destructive, security, functional and non-functional, software performance, usability and concurrent testing.

Testing of bugs is essential. If these bugs are ignored they could cost the programmer a huge monetary and even human loss. These bugs, if ignored, are dangerous. In 2015, a software glitch led to the postponing of a 3 billion debt sale by the English government. Automobile manufacturing company, Nissan had to call back more than a million cars because of failure in the airbag sensory detectors. The caffeine-induced company, Starbucks had to close sixty per cent of its stores in the United States due to system failure.

Software testing requires a particular skill set that needs a very logical mind and a good grasp of those skills. The more effectively you practice those skills, the easier it becomes for you to succeed in this field of software testing.
