Out of Bounds

While searching for more information about Boundary Value testing I stumbled across “Boundary Value Analysis & Equivalence Partitioning with Examples” by the website guru99 which gave a great explanation of what each is and gave an interactive part that you could type in values to see where they would fall on the specific examples. Boundary testing is checking the extreme values and the in-between vales and allows the tester to focus on the important values to be tested rather than go through and try to test every possible input. The great thing about this source is that it provides not only a textual explanation but also a visual and interactive one as well.
while Boundary testing focuses on the minimum and maximum and values between them, Equivalence partition checks even the values that are invalid and do not meet the requirements set by the program. For Example, An Equivalence partition would check for exceptions like if a person gave a negative value for money to be withdrawn from a bank account. I found this website extremely helpful because I was having trouble distinguishing between the two types since they are similar in some ways. personally I believe that Equivalence testing is the more sensible approach because it covers the values that would not and should not work for a system/program and makes sure that they are dealt with appropriately.
