The XYZ Bank supports a couple to buy a home under the following two approval requirements (R): R1 The couple must be currently employed full time. R2 The couple current combined annual total income must not be more than $100,000. Specifically, the couple combined annual total income must be between $0 and $99,999 (inclusive). The income is in integer value. 1a [5 points] Determine the equivalence classes for the above two approval requirements. 1b [7 points] Determine the boundaries of the equivalence classes identified in your answers to 1a. For each boundary, identify a value on the boundary, a value just below the boundary, and a value just above the boundary. 1c [8 points] You intend to perform defensive testing of the two approval requirements, R1 and R2. Design a set of test cases to test the two above approval requirements based on the equivalence classes and boundary values identified in your answers to 1a and 1b. Note: for invalid employment status, you only need to provide test cases for one invalid employment status.
