Comment tester unitairement les requêtes et les mutations GraphQL dans Go avec gqgen ?

Tests unitaires GraphQL dans Go

Lorsque vous travaillez avec GraphQL et Go, les tests unitaires sont cruciaux pour garantir l'exactitude et la fiabilité de votre code. Voici un exemple simple démontrant comment tester efficacement les requêtes et les mutations GraphQL à l'aide de Go, en tenant compte des frameworks que vous avez mentionnés :

<code class="go">package resolver_test

import (
    "testing"
    "github.com/99designs/gqlgen/client"
    "github.com/99designs/gqlgen/graphql/handler"
    "github.com/mrdulin/gqlgen-cnode/graph/generated"
    "github.com/mrdulin/gqlgen-cnode/graph/model"
    "github.com/mrdulin/gqlgen-cnode/graph/resolver"
    "github.com/mrdulin/gqlgen-cnode/mocks"
    "github.com/stretchr/testify/mock"
    "github.com/stretchr/testify/require"
)

// Define mock objects for UserService
type MockedUserService struct {
    mock.Mock
}

func (s *MockedUserService) GetUserByLoginname(loginname string) *model.UserDetail {
    args := s.Called(loginname)
    return args.Get(0).(*model.UserDetail)
}

func (s *MockedUserService) ValidateAccessToken(accesstoken string) *model.UserEntity {
    args := s.Called(accesstoken)
    return args.Get(0).(*model.UserEntity)
}

// Test MutationResolver_ValidateAccessToken
func TestMutationResolver_ValidateAccessToken(t *testing.T) {

    t.Run("should validate accesstoken correctly", func(t *testing.T) {
        // Create a mock UserService
        testUserService := new(mocks.MockedUserService)
        resolvers := resolver.Resolver{UserService: testUserService}

        // Create a GraphQL client
        c := client.New(handler.NewDefaultServer(generated.NewExecutableSchema(generated.Config{Resolvers: &resolvers})))

        // Define the expected user entity
        ue := model.UserEntity{ID: "123", User: model.User{Loginname: &loginname, AvatarURL: &avatarURL}}

        // Set the mock UserService to return the expected user entity
        testUserService.On("ValidateAccessToken", "abc").Return(&ue)

        // Define the query to test
        var resp struct {
            ValidateAccessToken struct{ ID, Loginname, AvatarUrl string }
        }
        q := `
      mutation { 
        validateAccessToken(accesstoken: "abc") { 
          id, 
          loginname, 
          avatarUrl 
        } 
      }
    `

        // Execute the query and assert the results
        c.MustPost(q, &resp)
        testUserService.AssertExpectations(t)
        require.Equal(t, "123", resp.ValidateAccessToken.ID)
        require.Equal(t, loginname, resp.ValidateAccessToken.Loginname)
        require.Equal(t, avatarURL, resp.ValidateAccessToken.AvatarUrl)
    })
}

// Test QueryResolver_User
func TestQueryResolver_User(t *testing.T) {

    t.Run("should query user correctly", func(t *testing.T) {
        // Create a mock UserService
        testUserService := new(mocks.MockedUserService)
        resolvers := resolver.Resolver{UserService: testUserService}

        // Create a GraphQL client
        c := client.New(handler.NewDefaultServer(generated.NewExecutableSchema(generated.Config{Resolvers: &resolvers})))

        // Define the expected user detail
        u := model.UserDetail{User: model.User{Loginname: &loginname, AvatarURL: &avatarURL}, Score: &score, CreateAt: &createAt}
