MissingMethodException when running integration tests

[Dale Lotts]

I'm writing some integration tests for by JSON API - the test run fine when run individually, however, the second or subsequent test fails when run together/

The failures are always MissingMethodException's referring to one of the dynamaic methods on a domain class - i.e. .save(), .addTo...(), etc.

I don't know when these methods are added or what about the test could possibly cause this behavior - any suggestions of where to look would be much appreciated.

Sample test that runs fine along but fails with MissingMethodException when run with other integration tests.

class ContactAPITests extends IntegrationTestCase {

    @Test

    void "Create customer with name only"() {

        def headers = ['Content-Type': 'application/json', 'Accept': 'application/json']

        def content = '{"name":"Customer Test"}'

        def expected = '{"id":2,"version":0,"addresses":[],"attributes":[],"companyName":null,"creditCards":[],"emailAddresses":[],"name":"Customer Test","occasions":[],"officeNotes":null,"phoneNumbers":[],"stripeCustomerID":null,"systemType":false}'

        // create new person

        sendRequest('/api/contact', 'POST', headers, content.bytes)

        assertEquals(201, response.status)

        assertEquals(expected, response.contentAsString)

        assertTrue(response.getHeader('Content-Type').startsWith('application/json'))

        // get list of persons

        sendRequest('/api/contact', 'GET', headers)

        assertEquals(200, response.status)

        assertEquals("[${expected}]".toString(), response.contentAsString)

        assertTrue(response.getHeader('Content-Type').startsWith('application/json'))

    }

}

Geez - hard to figure out but easy to fix.

Do not use @TestFor(...) in integration tests. =) Removing this annotation fixed the problem. =)
