Test Cases/Unit test for the /generate-presigned-url endpoint

[uzaxirr]

It is desired to have test cases for the /generate-presigned-url endpoint which gives a pre-signed url and videoID as output. the s3 SDK is needed to be mocked.

Here is a snippet that might be useful

// mockS3Client is a mock object that implements the S3 client interface
type mockS3Client struct {
	mock.Mock
}

// PutObjectRequest is a mock function that implements the S3 client's PutObjectRequest method
func (m *mockS3Client) PutObjectRequest(input *s3.PutObjectInput) (*s3.PutObjectOutput, error) {
	args := m.Called(input)
	return args.Get(0).(*s3.PutObjectOutput), args.Error(1)
}

// Presign is a mock function that implements the S3 client's Presign method
func (m *mockS3Client) Presign(input *http.Request, expiration time.Duration) (string, error) {
	args := m.Called(input, expiration)
	return args.String(0), args.Error(1)
}

// AbortMultipartUpload is a mock function that implements the S3 client's AbortMultipartUpload method
func (m *mockS3Client) AbortMultipartUpload(input *s3.AbortMultipartUploadInput) (*s3.AbortMultipartUploadOutput, error) {
	args := m.Called(input)
	return args.Get(0).(*s3.AbortMultipartUploadOutput), args.Error(1)
}

// AbortMultipartUploadRequest is a mock function that implements the S3 client's AbortMultipartUploadRequest method
func (m *mockS3Client) AbortMultipartUploadRequest(input *s3.AbortMultipartUploadInput) (*request.Request, *s3.AbortMultipartUploadOutput) {
	var args = m.Called(input)
	return args.Get(0).(*request.Request), args.Get(1).(*s3.AbortMultipartUploadOutput)
}

func setupRoutes(s3Client *mockS3Client) *gin.Engine {
	router := gin.Default()

	// Set up the route for the GeneratePresignedURL function
	router.GET("/presigned-url", func(c *gin.Context) {
		GeneratePresignedURL(
			c,
			s3Client,
		)
	})

	return router
}

func TestGeneratePresignedURL(t *testing.T) {
	// Create a mock object for the S3 service client
	mockS3Client := &mockS3Client{}

	// Define a function that will be used to mock the Presign method
	mockS3Client.On("Presign", mock.Anything).Return("https://my-presigned-url.com", nil)

	// Set up a test HTTP server and routes using the mock S3 client
	server := httptest.NewServer(setupRoutes(mockS3Client))
	defer server.Close()

	// Create a test HTTP request with the fileName and extension query params
	req, err := http.NewRequest("GET", server.URL+"/presigned-url?fileName=test.mp4", nil)
	if err != nil {
		t.Fatalf("Error creating HTTP request: %s", err)
	}

	// Make the HTTP request to the GeneratePresignedURL function
	res, err := http.DefaultClient.Do(req)
	if err != nil {
		t.Fatalf("Error making HTTP request: %s", err)
	}

	// Assert that the response status is 200 OK
	assert.Equal(t, http.StatusOK, res.StatusCode)

	// Read the response body
	resBody, err := ioutil.ReadAll(res.Body)
	if err != nil {
		t.Fatalf("Error reading response body: %s", err)
	}

	// Unmarshal the response body into a map
	var data map[string]interface{}
	err = json.Unmarshal(resBody, &data)
	if err != nil {
		t.Fatalf("Error unmarshalling response body: %s", err)
	}

	// Check that the response includes the expected pre-signed URL and video ID
	if data["preSignedURL"] != "https://my-presigned-url.com" {
		t.Errorf("Expected pre-signed URL 'https://my-presigned-url.com', got %s", data["preSignedURL"])
	}
	if data["videoID"] == nil {
		t.Error("Expected video ID in response, got nil")
	}
}
