The shopping cart example illustrates pairwise testing using a Unified Modeling Language (UML) state machine diagram. This test design is based on the shopping cart diagram. The design illustrates the target state model, in which each partition includes all the transitions leading to a particular target state. Some of the factor values are functionally dependent on the values of other factors. This design is converted from functionally dependent form (above) using the fixed values conversion procedure to insure that all allowed pairs of factor values are covered.

In the shopping cart example there are four leaf states: emptyCart, nonemptyCart, shopping, checkout. There are eight state transitions which are grouped into four partitions according to their target states:

# all states to emptyCart
# all states to nonemptyCart
# all states to shopping
# all states to checkout

There are 18 test factors with values as follows.

UPDATE CHECKOUT

The first 16 factors are program variables. Factor 17 is the current state, and factor 18 is the event triggering the expected transition. The newItem value indicates an item to place in the cart; n is the number of items in the cart (up to 3 in this test design). The first 3 items in the cart are indexed by 0, 1 and 2, so factors 3-6 are for the item in position 0, 7-10 for position 1, etc. For each cart position i, delChk[i] indicates whether the delete box is checked; item[i] identifies the item; qty[i] is the quantity of the item; newQ[i] shows a new quantity entered. Factors 15 and 16 give the values for i and q in the CHECK(i) and the QTY(i,q) events. These events are functionally dependent, but in this design their fixed values are given explicitly according to the values of i and q. The value n/a indicates that a factor is not applicable to the transition test case.

The items are placed in the cart starting at position 0. They are constrained to be different, to appear in separate cart positions. Otherwise, the item already in the cart would have its quantity incremented; a new cart position would not be filled. For example, when there are two different items, the test design constrains position 0 to have itemA or itemB; position 1 is constrained to have itemC.

In the shopping-nonemptyCart and checkout-nonemptyCart transitions, qty[0] is used as a value for newQ[0]. This indicates that the value shown for the new quantity is the same as the current quantity. Then newQ[0] is functionally dependent on qty[0]. (If qty[0] is 10, then so is newQ[0].) Factors newQ[1] and newQ[2] have similar dependencies on values of qty[1] and qty[2].

The test design is constructed from the functionally dependent form using the fixed values conversion procedure. Partitions 1, 3 and 4 are the same in both forms because their factor values are given explicitly, without functional dependence. Partition 2 (all states to nonemptyCart) is the only one that differs between the functionally dependent and fixed values forms. The relationship between the two forms of the target state design is presented in the shopping cart mapping table.

The test case generator request is given below. The partition prefix, e.g. E, indicates the target state (emptyCart) for each test case.

The shopping cart target state design has 217 test cases in 4 partitions in fixed values form. Partition 2 is the only partition that differs from functionally dependent form. All test cases start with an empty cart. The results tables follow.

The test cases in partition 1 test the allowed transitions from all states to the emptyCart state with all allowed pairs of factor values. Test case E7 is set up as illustrated below.

The items already in the cart are constrained to be different, to appear in separate cart positions, and blocks with the UPDATE event are constrained to yield an empty cart.

E7 is set up by placing itemA and itemC in the cart from the shopping page. The delete box is checked for itemA, and a new quantity 10 is entered. A new quantity 0 is entered for itemC. The update button is clicked to trigger the transition to emptyCart.

The test cases in partition 2 test the allowed transitions from all states to the nonemptyCart state with all allowed pairs of factor values. Test cases N2, N4, N5, N12 and N27 are set up as illustrated below.

The items already in the cart are constrained to be different, to appear in separate cart positions, and blocks with the UPDATE event are constrained not to yield an empty cart. In addition the values for newQ[0], newQ[1] and newQ[2] are constrained to be the fixed values of qty[0], qty[1] and qty[2] respectively for transitions from shopping and checkout. This is because the exit action of the cart state sets newQ[i] equal to qty[i]. (Any new quantity entered is abandoned if the cart is not updated.) So the value for newQ[i] is constrained to be the same as qty[i] before the transition back to nonemptyCart.

The events CHECK(i) and QTY(i,q) are expressed in terms of the fixed values of i and q as well. The fixed values conversion procedure is used to convert the functionally dependent values, qty[0], qty[1], qty[2], CHECK(i) and QTY(i,q), to fixed values form.

N2 is set up by placing itemA, itemB and itemC in the cart from the shopping page. New quantities of 0 for itemA, 0 for itemB and 0 for itemC are entered. The delete box is checked for itemA to trigger the transition to nonemptyCart.

N4 is set up by placing itemA, itemB and itemC in the cart from the shopping page. New quantities of 10 for itemA, 10 for itemB and 10 for itemC are entered; the update button is clicked. The delete boxes are checked for itemA, itemB and itemC. A new quantity of 0 is entered for itemC. Another new quantity of 1 is entered for itemC to trigger the transition to nonemptyCart.

N5 is set up by placing itemA, itemB and itemC in the cart from the shopping page. New quantities of 2 for itemA, 2 for itemB and 2 for itemC are entered; the update button is clicked. The shop button is clicked, and then another itemB is placed in the cart from the shopping page to trigger the transition to nonemptyCart.

N12 is set up by placing itemA, itemB and itemC in the cart from the shopping page. The checkout button is clicked, and then the cart button is clicked to trigger the transition to nonemptyCart.

N27 is set up by placing itemA, itemB and itemC in the cart from the shopping page. A new quantity of 10 is entered for itemB, and the update button is clicked. The delete boxes are checked for itemA and itemB. New quantities of 0 for itemA and 10 for itemC are entered. The update button is clicked to trigger the transition to nonemptyCart.

The test cases in partition 3 test the allowed transitions from all states to the shopping state with all allowed pairs of factor values. Test case S3 is set up as illustrated below.

The items already in the cart are constrained to be different, to appear in separate cart positions.

S3 is set up by placing itemB and itemC in the cart from the shopping page. New quantities of 2 for itemB and 2 for itemC are entered, and the update button is clicked. The delete boxes are checked for itemB and itemC. New quantities of 0 for itemB and 1 for itemC are entered. The shop button is clicked to trigger the transition to shopping.
