[英]Docker compose .Net Core NUnit Test and Redis
我有一个包含 API 和 NUnit 测试的 .Net Core 解决方案。 当我运行docker-compose up
,如果我不包含测试,API 就可以正常工作。 但是,如果我实施测试,则 docker compose 无法构建,并出现错误StackExchange.Redis.RedisConnectionException : It was not possible to connect to the redis server(s). UnableToConnect on redis-service:6379/Interactive
StackExchange.Redis.RedisConnectionException : It was not possible to connect to the redis server(s). UnableToConnect on redis-service:6379/Interactive
in command line。
我的Dockerfile

我docker-compose.yml
:

我的测试班:
namespace ReportApi.Test
{
class RedisCacheControllerTest
{
public IDatabase Cache { get; set; }
public RedisCacheController Controller { get; set; }
[SetUp]
public void Init()
{
// Set up Redis Cache
var redis = ConnectionMultiplexer.Connect("redis-service:6379");
var services = new ServiceCollection();
services.AddScoped(s => redis.GetDatabase());
var provider = services.BuildServiceProvider();
Cache = provider.GetService<IDatabase>();
// Create controller instance
Controller = new RedisCacheController(Cache);
}
[Test]
public void InsertRecordTest()
{
// Create a new instance of RedisCache
RedisCache redisCache = new RedisCache()
{
id = "testId",
value = "CacheData"
};
// If the redisCache object doesn't exist, check if it returns 200 OK;
// otherwise check if it returns 409 Conflict
if (Cache.StringGet(redisCache.id).Length() == 0)
{
Assert.IsInstanceOf<OkObjectResult>(Controller.Create(redisCache));
}
else
{
Assert.IsInstanceOf<ConflictObjectResult>(Controller.Create(redisCache));
}
}
[Test]
public void RetrieveRecordTest()
{
string key = "testId";
// If the record exists, check if it returns 200 OK;
// otherwise check if it returns 204 No Content
if (Cache.StringGet(key).Length() != 0)
{
Assert.IsInstanceOf<OkObjectResult>(Controller.Get(key));
}
else
{
Assert.IsInstanceOf<NoContentResult>(Controller.Get(key));
}
}
}
}
Redis 在 docker-compose.yml 中定义,只有在每个服务(在其中定义)都已经构建后才会运行。
因此,在构建 Dockerfile 时,还没有从 docker-compose 运行任何内容。
在这种情况下,人们通过互联网推荐不同的方法,例如: https : //medium.com/@christiansparre/integration-testing-with-docker-compose-and-visual-studio-team-service-83a1166055a8
但是,无论如何,我建议您不要在构建 Dockerfile 时运行测试。 相反,从您的 docker-compose.yml(上面的链接)运行它们。
您当前使用的方法的目标是确保您的容器映像在创建时已经过测试。 但是,你没有积分。 如果您的测试在镜像构建后失败,只需删除并不要使用它,如果容器不起作用,没有人要求您运行保持容器。
