Enhancement of automation testing system using Yocto project

Nowadays, in industries, Testing has become one of the important tasks. Testing is necessary for an effective performance of product and software applications. When companies having a mass production of hardware boards, it is necessary to do testing of each and every module of hardware like SPI, UART, GPIO, PWM, ADC, USB, Ethernet. If we do testing manually then it will significantly take more time, which we can be reduced by automation testing. But the solution is not an automation testing because automation testing also requires the same amount of system, for example for 300 boards 300 system is required. The only difference in manual and automation testing is that in automation testing it will require less human effort. Now we are focusing more on developing a solution in which many tests can be done on one single system i.e. for 300 boards only one system is required for testing hence this problem can be solved by Yocto Project. Yocto project have build the tool named Bitbake which is written in Python language, which works on multithreading and scheduling so that simultaneously you can test more boards on a single system. In this paper we did automation testing of GPIO pins using Yocto project.
