Go 中的 Pact 消费者测试。 dsl.Match 函数的问题

php editor Apple will share with you today a question about Pact consumer testing in Go. When using Pact for consumer testing, we often use the dsl.Match function to match specific fields in requests and responses. However, we may encounter some problems, such as fields not matching correctly. This article will delve into this issue and provide solutions to help you better deal with the challenges of Pact consumer testing.

Question content

I am writing pact consumer test using go. When I define the interaction I need to add the expected response object. The provider service is written in php and this is the response I expect:

return  [
            'status' => 'success',
            'data' => [
                'configuration' => associative array,
                'undeploy_configuration' => associative array,
                'meta_data' => associative array,
                'undeploy_lora_app_key' => string,
            ],
        ];

This is the object I created in go to represent the response I should get:

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"),
        }),
    })

However, when I run the test, I get this error:

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

This is the complete code:

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)
}

Workaround

The method you are using (match) takes a struct annotated with a struct tag (see https://github.com /pact-foundation/pact-go#auto-generate-matchers-from-struct-tags) specifies how structs should be matched. You've manually provided the struct with the correct matcher, so there's no need to wrap it in match at all.

Something like this should work:

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