7.1: know the purpose of testing and be able to design and use test plans and test data.

Keyword	Definition
actual result	description of what a program actually did when it was tested
expected result	description of what a program should do if it worked fully
test data	the specific values that will be input into a program in order to test one part of it
test plan	a list of ways in which a program will be tested to make sure it works fully

7.2: understand how to write code that accepts and responds appropriately to user input.

Keyword	Definition
input	the data that a program accepts in (e.g. from the user or a file)
output	the data that a program sends out (e.g. to the user or a file)
process	the calculations that take place to work out what outputs to send based on the inputs a program receives

7.3: use validation and exception handling to make programs robust

Keyword	Definition
presence check	type of validation where the program checks data for empty values
range check	type of validation where data is checked to see if it's between an expected minimum and maximum value
type check	type of validation where data is checked against what sort of data the program expects (e.g. integer, boolean, character or string)
validation	checking that input data is suitable for processing and doesn't contain anything that would cause an error to occur
