90. CONSUMER-DRIVEN CONTRACTS
93. CLIENT API { "foo": "bar" }
94. CLIENT API { "foo": "bar" } { "foo": "bar" } STUB
95. CLIENT BUILD #1 { "foo": "bar" } { "foo": "bar" } STUB
96. CLIENT BUILD #2 { "foo": ["bar"] } { "foo": "bar" } STUB
97. CLIENT BUILD #2 { "foo": ["bar"] }
98. CLIENT BUILD #2 { "foo": ["bar"] }
99. CLIENT API { "foo": "bar" }
100. CLIENT API { "foo": "bar" } THE STATUS CODE SHOULD BE 200 THE FOO PROPERTY SHOULD BE BAR
101. CLIENT API { "foo": "bar" } CONTRACT { "statusCode": 200, "body": { "foo": "bar" } }
102. CLIENT BUILD #1 { "foo": "bar" } CONTRACT { "statusCode": 200, "body": { "foo": "bar" } }
