Black box testing is also termed as functional testing. It ignores how the internal functionality of a system works and depends only what are the outputs on specified inputs. Source code availability is not an important in back box testing.
Hi
Software testing is of following types.
1.Blackbox testing.
2.Whitebox testing.
3.Greybox testing.
Blackbox testing: This is performed by the test
engineers on the front end of the application.
Test engineer's are least bother about source
code. They validates only through UI(user
interface) by giving the inputs and validating the application weather working as per client requirements or not.
Blackbox testing is done by test engineer's manually or can be done by using automation tools.
