What is meant by unit testing? It is a testing method where smallest pieces of code known as “units” are tested. A unit can be a property, a method, a subroutine or a function. Each software component is validated to know whether it is working as expected. It is performed during the coding phase of the software development process. https://www.evernote.com/shard/s430/client/snv?isnewsnv=true&noteGuid=cb4ad00a-c4c3-41ab-a2f7-95552516bf59&noteKey=pWj1uPTBv2t5KxhEBmS659G7qS-O8DwngNdpaaviA8JXAtLjWKh9_Md80g&sn=https%3A%2F%2Fwww.evernote.com%2Fshard%2Fs430%2Fsh%2Fcb4ad00a-c4c3-41ab-a2f7-95552516bf59%2FpWj1uPTBv2t5KxhEBmS659G7qS-O8DwngNdpaaviA8JXAtLjWKh9_Md80g&title=What%2Bis%2Bmeant%2Bby%2Bunit%2Btesting%253F
