Component	System component::Calculate
Feature	System feature::http://wiki.laptop.org/go/Calculate
Objective	Test objective::
Tools	Test tools::n/a
Setup	Test setup::n/a
Procedure	[[Test procedure::1. Open the XO machine 2. Run the Calculate Activity on XO machine 3. Test invalid inputs for the fours arithmetic operations 4. Test valid inputs for the fours arithmetic operations]]
Expected Results and Pass Criteria	[[Pass criteria::1. When test the invalid inputs,like letters, the calculation should do not work out. 2. When test the valid inputs, the calculation should work out well, except any number divided by 0 (any number / 0), since it should be undefined for division.]]
Comments	[[More notes::The following is the case sequence to test the four arithmetic operations(addition, subtract, multiply, division ): input1(pos, neg, 0, invalid(a-z)), input2(pos, neg, 0, invalid(a-z)) ,operations(+,-,*,/) We build 14 tests for this test case by pairwise.]]

For example, when input1 is a, and input2 is 1, then the calculation should do not work out for a + 1. The invalid inputs values are from a to Z.]]	Created::2009/03/26

However, we just test the numbers as the inputs for the test case. We need do more tests to verity truth values for the fours arithmetic operations.]]	Created::2009/03/26
