Go中的Pact消费者测试.dsl的问题.匹配功能

Question

我正在用Go编写一个Pact消费者测试。在定义交互时，我需要添加预期的响应对象。提供者服务是用PHP编写的，这是我期望的响应:

return  [
'status' => 'success',
'data' => [
'configuration' => Associative Array,
'undeploy_configuration' => Associative Array,
'meta_data' => Associative Array,
'undeploy_lora_app_key' => String,
],
];

这是我在Go中创建的对象，用来表示我应该得到的响应:

deviceConfigurationResponse := dsl.Like(map[string]interface{}{
"status": "success",
"data": dsl.Like(map[string]interface{}{
"configuration": dsl.MapMatcher{
"config1": dsl.String("value1"),
"config2": dsl.String("value2"),
},
"undeploy_configuration": dsl.MapMatcher{
"undeploy1": dsl.String("value3"),
"undeploy2": dsl.String("value4"),
},
"meta_data": dsl.MapMatcher{
"meta1": dsl.String("info1"),
"meta2": dsl.String("info2"),
},
"undeploy_lora_app_key": dsl.String("example_undeploy_lora_app_key"),
}),
})

然而，当我运行测试时，我得到这个错误:

--- FAIL: TestGetDeviceConfiguration (1.79s)
panic: match: unhandled type: interface {} [recovered]
panic: match: unhandled type: interface {}

这是完整的代码:

func TestGetDeviceConfiguration(t *testing.T) {
// Create Pact client
pact := &dsl.Pact{
Consumer: "consumer",
Provider: "provider",
PactDir:  "./pacts",
}
defer pact.Teardown()
deviceConfigurationResponse := dsl.Like(map[string]interface{}{
"status": "success",
"data": dsl.Like(map[string]interface{}{
"configuration": dsl.MapMatcher{
"config1": dsl.String("value1"),
"config2": dsl.String("value2"),
},
"undeploy_configuration": dsl.MapMatcher{
"undeploy1": dsl.String("value3"),
"undeploy2": dsl.String("value4"),
},
"meta_data": dsl.MapMatcher{
"meta1": dsl.String("info1"),
"meta2": dsl.String("info2"),
},
"undeploy_lora_app_key": dsl.String("example_undeploy_lora_app_key"),
}),
})
// Define the expected interaction with the provisioning-service
value := "123456789"
pact.
AddInteraction().
Given("Device configuration exists for the given device ID").
UponReceiving("A request to get device configuration").
WithRequest(dsl.Request{
Method:  "GET",
Path:    dsl.String(fmt.Sprintf("/api/prov/state/%s/configuration", value)),
Headers: dsl.MapMatcher{"Accept": dsl.String("application/json")},
}).
WillRespondWith(dsl.Response{
Status:  200,
Headers: dsl.MapMatcher{"Content-Type": dsl.String("application/json")},
Body:    dsl.Match(deviceConfigurationResponse),
})
// Test the OnSessionEstablished function
var test = func() error {
cache := new(CacheMock)
deviceConfigGetter := new(DeviceConfigGetterMock)
_, err := GetDeviceConfiguration(value)
cache.AssertExpectations(t)
deviceConfigGetter.AssertExpectations(t)
return err
}
// Verify the interaction with the provider
var err = pact.Verify(test)
assert.NoError(t, err)
}

您正在使用的方法(Match)采用带结构标记的结构体(参见https://github.com/pact-foundation/pact-go#auto-generate-matchers-from-struct-tags)，这些标记指定了结构体中的各种项应该如何匹配。您已经手动提供了具有正确匹配器的结构，因此根本不需要将其包装在Match中。

应该这样做:

WillRespondWith(dsl.Response{
Status:  200,
Headers: dsl.MapMatcher{"Content-Type": dsl.String("application/json")},
Body:    deviceConfigurationResponse,
})
