black box testing is a testing that mainly concentrate on the functional department of a software program.Black box testing is complementry to white box testing.black box testing deals with the external view of the program.In this testing, test case don't know about the internal structure of the program.Black box testing starts when the white box testing stops.The black box testing is mainly done by programmer of every level in one or the other way. Suppose,we have a program of finding the greatest out of three numbers.For this, black box testing will be as follows:-- 1)What are the required inputs for this program? lets say----4,6,3 2)The output for this will be 6. 3)Now if the answer is 6, then the program is O.K otherwise, the program is wrong.

In Black Box testing the practical approach would be following: 1.) Develop Test-to-pass test cases; apply valid inputs to insure that s/w function does what it is intended to do in correct way. 2.) Error-Forcing; develop test cases to force all the error messages to appear. 3.) Now start thinking like a cracker; design test cases to break the s/w. Use Methods: 1- Process and Data flow diagrams 2. Equivalence Partitioning 3. Boundary Value Analysis 4. Cause & Effect diagram Automated scripts are useless until there is a clear need of reuse. Do not rely on Record and Play back feature of automated tools as this is nothing than wasting time. you know, you will encounter any bug while you will generate test script and this you will do manually.

TOOLS:generally all r using winrunner. TECHNIQUES: Equivalance Partioning(EP):divide the inputs,outputs etc into the area which r the same. Boundary Value Analysis(BVA):rather than selecting EP it selects just above or below Error Guessing(EG): its take a large way to get it determined. eg: the way of guessing is a follows- 1.the text field is empty 2.the text field hv some inputs 3.all the inputs hv same values....

Equivalence testing is to divide the given range into equal partitions where value from each partition can serve the purpose of all other values in that range.So, no. of values becomes equal to number of partitions.
