Methods used by large companies are different than that used by medium and small companies. Who the tester works for – This is a major factor in determining the types of system testing a tester will use.The specific types used by a tester depend on several variables. There are over 50 different types of system testing. What Types of System Testing Should Testers Use? This is when the tester focuses his/her attention on the interactions between the hardware and software during system testing. Hardware/Software Testing – IBM refers to Hardware/Software testing as “HW/SW Testing”.Testers might make a list of additional functionalities that a product could have to improve it during functional testing. Functional Testing – Also known as functional completeness testing, Functional Testing involves trying to think of any possible missing functions.Migration Testing – is done to ensure that the software can be moved from older system infrastructures to current system infrastructures without any issues.Recovery Testing – is done to demonstrate a software solution is reliable, trustworthy and can successfully recoup from possible crashes.It also makes sure no old bugs appear from the addition of new software modules over time. Regression Testing – involves testing done to make sure none of the changes made over the course of the development process have caused new bugs.Load Testing – is necessary to know that a software solution will perform under real-life loads.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.Below we have listed types of system testing a large software development company would typically use For an exhaustive list of software testing types click here. There are more than 50 types of System Testing. System testing done by a professional testing agent on the completed software product before it is introduced to the market.Īcceptance testing – beta testing of the product done by the actual end users. It is crucial to test each module’s effect on the entire program model. One piece of software can contain several modules which are often created by several different programmers. This involves testing of each individual code module. Integration testing done before, during and after integration of a new module into the main software package. Unit Testing is normally done by the programmer who writes the code. Unit testing performed on each module or block of code during development. These are the steps taken to fully test new software in preparation for marketing it: The following is a list of software testing categories arranged in chronological order. Software Testing HierarchyĪs with almost any software engineering process, software testing has a prescribed order in which things should be done. You need to build detailed test cases and test suites that test each aspect of the application as seen from the outside without looking at the actual source code. That is a very basic description of what is involved in system testing. Testing of the user’s experience with the application.Verify thorough testing of every input in the application to check for desired outputs.This is also called End to End testing scenario. Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole.System Testing involves testing the software code for following System test involves the external workings of the software from the user’s perspective. In contrast, black box or System Testing is the opposite. White box testing is the testing of the internal workings or code of a software application. System test falls under the black box testing category of software testing. What Types of System Testing Should Testers Use?Ĭlick here if the video is not accessible.
