Grails 3.1.9 Functional Test Port
With Grails 3.1.9 and above we now get a default port for Functional tests that is randomly assigned. This is a great feature that was added in with this commit.
While this is a nice addition our tests which were not using Geb were left broken this is due to the fact we now need to know what port was selected for a given run of the tests. So our old test:
@Integration
class UserEndpointSpec extends Specification {
def "POST new user"() {
given:
ResponseEntity<Map> resp
RestTemplate restTemplate = new RestTemplate()
def requestBody = [
email: 'phil@aol.com',
fullName: 'Phil',
password: 'password',
username: 'phil'
]
when:
resp = restTemplate.postForEntity("http://localhost:8080/users", requestBody, Map)
then:
resp.statusCode == HttpStatus.NO_CONTENT
}
}
Was broken since the app no longer started on 8080, but we can fix that with a new property that the @Integration annotation adds which is serverPort so the test becomes:
@Integration
class UserEndpointSpec extends Specification {
def "POST new user"() {
given:
ResponseEntity<Map> resp
RestTemplate restTemplate = new RestTemplate()
def requestBody = [
email: 'phil@aol.com',
fullName: 'Phil',
password: 'password',
username: 'phil'
]
when:
resp = restTemplate.postForEntity("http://localhost:${serverPort}/users", requestBody, Map)
then:
resp.statusCode == HttpStatus.NO_CONTENT
}
}
If you are wondering how serverPort is actually set you can see it happening inside IntegrationTestMixinTransformation. It will add a property to the test class with the port.
