Students Learn About:- the
selection of appropriate test data, including:
- data that test all the pathways
through the algorithm
- data that test boundary conditions
‘at’, ‘above’ and ‘below’ values upon which decisions are based
- data where the required answer
is known
- data which is outside the
expected values
- the
need for thorough test data
- testing
both algorithms and coded solutions with test data such as:
- desk checking an algorithm
- stepping through a coded
solution line by line
| Students Learn To:
- determine the expected result given test data
- compare the actual output from a piece of code with the expected output from test data to detect logic errors
- create a set of appropriate test data and use it to verify the logic in a solution
- perform a desk check by producing a table showing the changes to the content of variables as the algorithm or code is stepped through manually
