Software testing is the process of software validation and verification. It helps to ensure that software meets the requirements specified by the customer and software developers. It can be done manually or with automated tools. In this article, we will outline the different types of software testing that are used to ensure quality.
Many software developers are now using codeless test automation tools to make their software testing processes more efficient. The kinds of tests that are performed on software, to look for errors of all kinds, include:

Unit testing is a software development process in which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.
Integration testing is a type of software testing that aims to verify the proper functioning of an integrated software system. The process of integration testing involves combining individual software modules, testing them as a group, and then verifying the functionality of the resulting integrated software.
Acceptance testing is a software testing process in which software is tested for compliance with the requirements specified by the customer or user. Acceptance testing is usually done by the customer or user but can also be carried out by software developers or software testers.
System testing aims to verify the functioning of a complete software system. The system under test can be a software application, a hardware system, or a combination of both.
Regression testing is a process of testing software that is used to verify that software changes (such as bug fixes, new features, or software updates) have not introduced new bugs.
Performance testing is used to verify that software can handle the required amount of work or transactions.
Security testing is a method of testing used to verify that software is secure from external threats, such as viruses, worms, and Trojan horses.
Usability testing is a process of testing that is used to verify that software is easy to use and understand.
Compatibility testing is a software testing process that is used to verify that software can run on different hardware platforms, operating systems, and software applications.
Load testing also called “stress testing”, is a software testing process that is used to verify that software can handle the required amount of work or transactions.
Scalability testing, also called “capacity planning”, is a software testing process that is used to verify that software can handle the required amount of work or transactions. Scalability testing is another job for those involved in the software’s production.
Many of these tests will be carried out by software testers and developers. They must be either carried out by experts or by automated systems that are also often codeless and so do not require expertise. That is where this is applicable and possible. Businesses can choose what approach to take with each different piece of software. Where they can go automated it is generally the best approach. It is good to have all the options.
Bearing in mind that software can be for private individuals or businesses of all sizes, it is important to know just how much usage it can realistically cope with. This can only be determined through testing. It is not everything that can be anticipated when coding necessarily.
Software testing is important, and the above tests are all part of the process when companies are looking to test as many of the areas as possible that ensure effective performance. That is in the real world where businesses and customers interact together.
