Unit testing is the basic method of checking errors in a program and the codes in the program. The syntax and the logical errors in a program and codes are identified in this testing category. This may be done by a single tester or a group of testers to ensure that there is no room for future errors. More info on unit testing an error can be corrected before moving to the next stage. The unit testing is the most sensitive among all the software testing methods since errors not identified are passed to the integration testing method.
