SpringCloud 方案3：無輸出消息

對(duì)于給定的合同：

Groovy DSL。 

			def contractDsl = Contract.make {
				label 'some_label'
				input {
					messageFrom('jms:delete')
					messageBody([
							bookName: 'foo'
					])
					messageHeaders {
						header('sample', 'header')
					}
					assertThat('bookWasDeleted()')
				}
			}

YAML。 

label: some_label
input:
  messageFrom: jms:delete
  messageBody:
    bookName: 'foo'
  messageHeaders:
    sample: header
  assertThat: bookWasDeleted()

創(chuàng)建了以下JUnit測(cè)試：

					'''
// given:
 ContractVerifierMessage inputMessage = contractVerifierMessaging.create(
	"{\\"bookName\\":\\"foo\\"}"
, headers()
	.header("sample", "header"));

// when:
 contractVerifierMessaging.send(inputMessage, "jms:delete");

// then:
 bookWasDeleted();
'''

然后將創(chuàng)建以下Spock測(cè)試：

					'''
given:
	 ContractVerifierMessage inputMessage = contractVerifierMessaging.create(
		\'\'\'{"bookName":"foo"}\'\'\',
		['sample': 'header']
	)

when:
	 contractVerifierMessaging.send(inputMessage, 'jms:delete')

then:
	 noExceptionThrown()
	 bookWasDeleted()
'''
