The following is a list of software testing categories arranged in chronological order. These are the steps taken to fully test new software in preparation for marketing it:

    • Unit testing – testing performed on each module or block of code during development. Unit Testing is normally done by the programmer who writes the code.


    • Integration testing – testing done before, during and after integration of a new module into the main software package. This involves testing of each individual code module. One piece of software can contain several modules which are often created by several different programmers. It is crucial to test each module’s effect on the entire program model.


    • System testing – testing done by a professional testing agent on the completed software product before it is introduced to the market.


  • Acceptance testing – beta testing of the product done by the actual end users.

Different Types of System Testing

There are more than 50 types of System Testing. For an exhaustive list of software testing types click here. Below we have listed types of system testing a large software development company would typically use

    1. Usability Testing – Usability Testing mainly focuses on the user’s ease to use the application, flexibility in handling controls and ability of the system to meet its objectives


    1. Load Testing – Load Testing is necessary to know that a software solution will perform under real-life loads.


    1. Regression Testing- – Regression Testing involves testing done to make sure none of the changes made over the course of the development process have caused new bugs. It also makes sure no old bugs appear from the addition of new software modules over time.


    1. Recovery Testing – Recovery testing is done to demonstrate a software solution is reliable, trustworthy and can successfully recoup from possible crashes.


    1. Migration Testing – Migration testing is done to ensure that the software can be moved from older system infrastructures to current system infrastructures without any issues.


    1. Functional Testing – Also known as functional completeness testing, Functional Testing involves trying to think of any possible missing functions. Testers might make a list of additional functionalities that a product could have to improve it during functional testing.


  1. Hardware/Software Testing – IBM refers to Hardware/Software testing as “HW/SW Testing”. This is when the tester focuses his/her attention on the interactions between the hardware and software during system testing.

What Types of System Testing Should Testers Use?

There are over 50 different types of system testing. The specific types used by a tester depend on several variables. Those variables include:

  • Who the tester works for – This is a major factor in determining the types of system testing a tester will use. Methods used by large companies are different than that used by medium and small companies.
  • Time available for testing – Ultimately, all 50 testing types could be used. Time is often what limits us to using only the types that are most relevant for the software project.
  • Resources available to the tester – Of course some testers will not have the necessary resources to conduct a testing type. For example, if you are a tester working for a large software development firm, you are likely to have expensive automated testing software not available to others.
  • Software Tester’s Education – There is a certain learning curve for each type of software testing available. To use some of the software involved, a tester has to learn how to use it.
  • Testing Budget – Money becomes a factor not just for smaller companies and individual software developers but large companies as well.
