如何在 C# 中为基于操作的方法（例如在 xunit 中插入数据）编写单元测试

Question

嗨，我正在学习单元测试，我有两种方法可以更新并创建内容条目。该功能工作正常，但我不知道如何为此功能编写单元测试。

以下是更新条目的方法

public async Task UpdateEntryAsync(string contentTypeId, string entryId, int? version, string endpoint)
{
    var entryRequest = await _httpClient.GetAsync($"{endpoint}/{entryId}");
    var entryContent = await entryRequest.Content.ReadAsStringAsync();
    dynamic getEntry = JsonConvert.DeserializeObject(entryContent);

    //Update the PreviousSlug with current slug
    getEntry.fields.previousSlug = getEntry.fields.slug;
    var updatedEntryJson = JsonConvert.SerializeObject(getEntry);
    var updatedEntryContent = new StringContent(updatedEntryJson, Encoding.UTF8, "application/json");

    // Set headers for update request
    updatedEntryContent.Headers.Add("X-Contentful-Content-Type", contentTypeId);
    updatedEntryContent.Headers.Add("X-Contentful-Version", version.ToString());
    
    await _httpClient.PutAsync($"{endpoint}/{entryId}", updatedEntryContent);

    version++;
    updatedEntryContent.Headers.Remove("X-Contentful-Version");
    updatedEntryContent.Headers.Add("X-Contentful-Version", version.ToString());
    await _httpClient.PutAsync($"{endpoint}/{entryId}/published", updatedEntryContent);
}

以下方法用于创建和发布：

public async Task CreateAndPublishRedirectEntryAsync(string entryId, string previousSlug,   
    string slug)
    {
        var endpoint = "entries";

        var referenceEntry = new
        {
            sys = new { type = "Link", linkType = "Entry", id = entryId }
        };

        var fields = new RedirectionManager
        {
            PreviousSlug = new Dictionary<string, string> { { "en-GB", previousSlug } },
            CurrentSlug = new Dictionary<string, string> { { "en-GB", slug } },
            StatusCode = new Dictionary<string, int> { { "en-GB", 301 } },
            CurrentArticle = new Dictionary<string, dynamic> { { "en-GB", referenceEntry } }
        };

        var redirectEntry = JsonConvert.SerializeObject(new { fields });
        var content = new StringContent(redirectEntry, Encoding.UTF8, "application/json");
        content.Headers.Add("X-Contentful-Content-Type", "redirectManager");

        var redirectResponse = await _httpClient.PostAsync(endpoint, content);
        var redirectResponseContent = await redirectResponse.Content.ReadAsStringAsync();
        var entry = JsonConvert.DeserializeObject<ContentType>(redirectResponseContent);

        if (!redirectResponse.IsSuccessStatusCode)
        {
            return;
        }

        await _httpClient.PutAsync(endpoint, content);
        content.Headers.Add("X-Contentful-Version", "1");
        await _httpClient.PutAsync($"{endpoint}/{entry.Sys.Id}/published", content);
    }

我无法对其他答案添加评论，但是 github 的创建者在另一个答案上对mockhttp的使用有很好的描述 在单元测试中模拟 HttpClient
