What are the 4 types of test data? | Normal, Abnormal, Extreme, Boundary |
What is a normal test data? | consist of values which are accepted by algorithm |
What is abnormal test data? | consist of values which are expected to be rejected by the algorithm |
What is extreme test data? | consist of smallest and largest possible values which are expected to be accepted by algorithm |
What is boundary test data? | used to determine where the smallest and largest values occur (used to find the extreme)(around the edge) |
What is the definition of validation? | checking if a value is reasonable before being accepted into a computer system |
Name the 6 types of validation check | Range, length, format, type, presence, character, check digit |
What is a range check? | checks if a number input is in a specified range (e.g between 0 and 25) |
What is a length check? | checks if input contains certain number of characters in the range (8 digit and above) |
What is a type check? | checks if data input is a certain type (string or integer) |
What is format check? | checks if data is inputted in certain format (email) |
What is presence check? | checks if data is entered and value isn't null |
What is character check? | checks if string input does not contain any invalid character or symbols |
What is verification? | checking if data has been accurately input into a computer |
What are the 4 types of verification? | double entry, screen/visual check, parity check, checksum |
What is double entry? | data is input twice. Computer checks if both entries match |
What is screen/visual check? | after user inputs data, computer displays input for user to confirm that it is correct |
how does the not equal sign look like? | <> |
What statements does IF statement use? | IF, THEN, ELSE, ENDIF |
What statements does CASE statement use? | CASE, OF, OTHERWISE, ENDCASE |
Go read the example of CASE statement in notes | okay |
Name 3 loop statements | WHILE, REPEAT, FOR |
What is the definition of WHILE statement? | a repetition continues while a condition is true |
What are the statements in WHILE statement? | WHILE, DO, ENDWHILE |
What is the definition of REPEAT statement? | a repetition which continues until a condition is true |
What are the statements of REPEAT statement? | REPEAT, UNTIL |
What is the definition of FOR statement? | a set repetition |
What are the statements used in FOR statement? | FOR, TO, NEXT |
