Software testing basically involves the use of certain techniques in order to fix any bugs or glitches in the software of any device and various types of testing techniques in software testing are used. The purpose is to ensure that the software runs fine and can be used without any issues or faults in a device. Have you ever noticed how new models of phones, printers, computers and laptops are released every few months? Well, these products are launched into the market after certain types of testing techniques in software testing are used.
There are some types of testing techniques in software testing that take into the account the fact that the code of the software has been changed. The change of the code can have an impact upon the device and these bugs then have to be dealt with so that the code and the software are compatible with one another. Only when this happens, the device can function efficiently. If anything goes wrong with the software and if bugs are found, the software is fixed so that it can work properly and then, it is included in the newer model of a device. You know how Samsung and Apple keep releasing newer models of the same phone? That is because the devices that their software is installed into are tested for bugs and glitches and new and updated software is released every few months to ensure that the device runs smoothly.
In some cases the functionality of the software is tested and these types of testing technique in software testing are known as unit regression testing. Where these types of testing techniques in software testing are concerned, they are used to perfect the software so that it functions properly. Though it does so to a great extent, the functionality is still affected by glitches and bugs every now and then.
In some cases additional variables are added to the software of a device and when this is done the types of testing techniques in software testing are used in order to check out the impact of the addition of a new variable to software with other variables in the software. The only issue is that other variables are not considered. The only variable taken into account is the new one. These types of testing techniques in software testing are known as partial regression tests.
Another of the many types of testing techniques in software testing is sanity testing. What happens in these types of testing techniques in software testing is that sometimes an application may crash for some reason or the other. If it crashes all the time there is an obvious need for it to be corrected. Though in some cases this may be due to the fact that the software in the device is outdated but in other instances this occurs for technical reasons which are fixed by the manufacturer.
These are some of the types of testing techniques in software testing though there are many others that are more complicated!
