If sale < 1000
Commission = 10% * sale
If sale >= 1000
Commission = 10%*1000 + 15%*(sale – 1000)
if sale > 1800
Commission = 10%*1000+ 15%*800+ 20%* (ราคาขาย1800)

Please answer the question is
Which Test case from test script file that are created following
the test case table to be fail. And Tester consults with
programmer, the program should be revised or not.
Question#2
1. Please
swap
between
programmer
and
tester
responsibility. Programmer creates a new java class as
Triangle.java following the pseudo code. As tester is ready
to create TriangleTest.java following the test case table as
below,
2. Tester and programmer check the test cases is coverage
how many percentage by EclEmma tool. Must create test
cases coverage the program at least 90%.
