I am using spring cloud contract (1.1.0) but i am completly stuck when I want to use Pageable
The following example is working, without the pageable
@GetMapping("/employees")
@Timed
public List<EmployeeDTO> getAllEmployees() {
log.debug("REST request to get all Employees");
List<Employee> employees = employeeRepository.findAll();
return employeeMapper.employeesToEmployeeDTOs(employees);
}
And this one is using the pageable
@GetMapping("/employees")
@Timed
public ResponseEntity<List<EmployeeDTO>> getAllEmployees(@ApiParam Pageable pageable)
throws URISyntaxException {
log.debug("REST request to get a page of Employees");
Page<Employee> page = employeeRepository.findAll(pageable);
HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(page, "/api/employees");
return new ResponseEntity<>(employeeMapper.employeesToEmployeeDTOs(page.getContent()), headers, HttpStatus.OK);
}
My contract is here. Working for the first example, not for the second
import org.springframework.cloud.contract.spec.Contract
[
Contract.make {
name("get all")
request {
method 'GET'
url('/api/employees?sort=id,desc')
}
response {
status 200
body([
[id : 1,
firstName : value(consumer('test'), producer(regex('[a-zA-Z0-9]{1,255}'))),
lastName : value(consumer('test'), producer(regex('[a-zA-Z0-9]{1,255}'))),
phoneNumber : value(consumer('test'), producer(regex('[a-zA-Z0-9]{1,255}'))),
salary : value(consumer(1000), producer(regex('[0-9]{1,10}'))),
commissionPct : value(consumer(1000), producer(regex('[0-9]{1,10}')))
],
[id : 2,
firstName : value(consumer('test2'), producer(regex('[a-zA-Z0-9]{1,255}'))),
lastName : value(consumer('test2'), producer(regex('[a-zA-Z0-9]{1,255}'))),
phoneNumber : value(consumer('test2'), producer(regex('[a-zA-Z0-9]{1,255}'))),
salary : value(consumer(2000), producer(regex('[0-9]{1,10}'))),
commissionPct : value(consumer(2000), producer(regex('[0-9]{1,10}')))
]
])
headers {
contentType('application/json;charset=UTF-8')
}
}
}
]
And the stack trace :

What should I do ? What should I modify to make it works ?
But what exactly are you trying to achieve? What you've presented in the example is actually a single body that contains two elements. Is that what you wanted to send? Or would you want with the first call the first element and then the second. If that's the case then you do a stateful case with scenarios http://cloud.spring.io/spring-cloud-contract/1.0.x/#_scenarios . You'd need to do 2 separate contracts.
Another question is if you really need to test if paging works. You want to test that the contract is valid and it will be by sending the request once only (or I'm missing sth that you want to test?).
UPDATE:
I think it's related to Spring Data + Rest Assured. Please check out this issue - Isolated Controller Test can't instantiate Pageable
