S3 SDD Unit 2 - 5. Testing

What is the purpose of testing?

• To make sure that your program has no errors

• To write more code

• To delete your program

• To slow down the process

Testing a program means that you have to run it to see whether it does what you _________.

• expect

• ignore

• forget

• repeat

To test your program you should use sensible ________ and construct a ________.

• test data, test table

• random data, summary table

• input data, result chart

• output data, frequency table

What is the definition of Normal test data?

• Data that will be expected in the program

• Data that is always incorrect

• Data that is never used in testing

• Data that causes the program to crash

What is the definition of Extreme test data?

• Data on the edge of what is expected, the lowest or highest acceptable value.

• Data that is always within the normal range of values.

• Data that is randomly generated without any restrictions.

• Data that is never used in any testing process.

What is the definition of Exceptional test data?

• Data that is not expected, a value above or below what is expected.

• Data that is always within the expected range.

• Data that is used for normal operations only.

• Data that is always correct and valid.

When a programmer is inputting code and testing it to see if it works, the code won’t always work. This may be because of errors in the code. The types of errors programmers make come into how many categories?

• Two

• Three

• Four

• Five
