What is Software Testing

Testing the Quality with right platform

System TestingUnit Testing Integration Testing

Individual units or modules are tested. It involves testing of source code by developers.

Individual modules are grouped together and tested. The purpose is to determine that modules are working as expected once they are integrated.

Testing is performed on the whole system by checking whether the system or application meets the requirement specification document.

Cross-Compiler Vs Host-Compiler (1/2)

What is a native compiler:

A native compiler is a compiler that works on a compilation for the same technology on which it runs.

What is a cross compiler :

A compiler which can convert instructions into machine code or low-level code for a computer other than that on which it is run.
