我不明白模拟在Grails 4.0中如何工作。 我有一个失败的单元测试(这只是真实测试的一个说明,真实测试实际上涉及控制器):
import com.myapp.MySearchService
class ApiControllerSpec extends Specification implements ControllerUnitTest<ApiController> {
def setup() {
}
def cleanup() {
}
void "test listSources"() {
given:
def mock = Mock(MySearchService) {
find(_) >> [["label": "abc", "description": "xsad"]]
}
when:
System.out.println(mock.find(''))
then:
1 * mock.find(_) >> [["label": "abc", "description": "xsad"]]
}
有错误
Too few invocations for:
1 * mock.find(_) >> [["label": "abc", "description": "xsad"]] (0 invocations)
Unmatched invocations (ordered by similarity):
1 * mock.invokeMethod('find', [<java.lang.String@0 value= hash=0>])
at org.spockframework.mock.runtime.InteractionScope.verifyInteractions(InteractionScope.java:93)
at org.spockframework.mock.runtime.MockController.leaveScope(MockController.java:77)
at toe.ApiControllerSpec.test listSources(ApiControllerSpec.groovy:29)
和标准输出
null
有趣的是,如果我使用一个非常简单的测试类而不是MySearchService ,则可以正常工作。因此,我假设它必须与Grails / Spring的设置方式有关。这也可能解释了以下几行:
Unmatched invocations (ordered by similarity):
1 * mock.invokeMethod('find', [<java.lang.String@0 value= hash=0>])
但是我该如何设置呢?我在文档的任何地方都找不到。感谢您的帮助!

模拟的语法不正确-这是在Grails 4.0.1中测试的工作示例
void "test something"() {
given:
def mock = Mock(SearchService) {
1 * find(_) >> ['foobar'] // note the interaction count is required when defining this way.
}
when:
def result = mock.find('')
then:
result == ['foobar']
}
请参阅-http://spockframework.org/spock/docs/1.0/interaction_based_testing.html-部分:Declaring Interactions at Mock Creation Time
请注意,Grails文档中可能没有此内容,因为没有任何Grails特定信息,只有Spock。

这已经不是一个很好的解决方法:
void "test listSources"() {
given:
def mock = Mock(MySearchService) {
invokeMethod('find', _) >> [["label": "abc", "description": "xsad"]]
}
when:
System.out.println(mock.find(''))
then:
1 * mock.invokeMethod('find', _) >> [["label": "abc", "description": "xsad"]]
}
