Boundary value analysis as the name stands is testing between the values on a set boundary. One value lesser and One value higher will be taken for testing and testing takes place to make sure the desired values work bug free. For example if we take values from 0 to 10, for boundary value analysis we pick from -1 to 11. When it comes to decision table testing, it is checking all the possibilities in True or False method. If we pick 2 fields, there will be 4 tables in decision table testing. For example, if we choose Sign in page and take the 2 fields, user name and password, the conditions for testing can be correct user name & correct password, correct username & wrong password, wrong username & correct password and wrong username & wrong password. We will will get 4 columns in the combination of T&T, T&F, F&T and F&F. Use case testing is checking the possibilities of finding bugs. For a sign in page, there will be numerous possibilities and combinations to test the product.
