ABP Framework version: v6.0.1
UI type: MVC
DB provider: EF Core
Tiered (MVC) or Identity Server Separated (Angular): no
Exception message and stack trace:
Steps to reproduce the issue:"

I have a solution with several modules added (one of them is called Core). In Core.Domain I have an entity called Attachments (Attachments are files that users can upload to the system). In Core.Domain I have AttachmentDataSeederContributor where I seed one attachment. As part of this seed data, I have a need to save the file contents in my seed data to blob storage.

When I run DBMigrator, my data seeds as expected. However, when I attempt to run my tests, I receive the following error for all tests: Message: Volo.Abp.AbpInitializationException : An error occurred during the initialize Volo.Abp.Modularity.OnApplicationInitializationModuleLifecycleContributor phase of the module PlatformNext.Core.CoreTestBaseModule, PlatformNext.Core.TestBase, Version=0.1.0.0, Culture=neutral, PublicKeyToken=null: An exception was thrown while activating PlatformNext.Core.Attachments.AttachmentDataSeederContributor -> λ:Volo.Abp.BlobStoring.IBlobContainer -> Volo.Abp.BlobStoring.BlobContainer1[[Volo.Abp.BlobStoring.DefaultContainer, Volo.Abp.BlobStoring, Version=6.0.1.0, Culture=neutral, PublicKeyToken=null]]..

No BLOB Storage provider was registered! At least one provider must be registered to be able to use the BLOB Storing System.

Hi,

You need to configure a BLOB Storage provider: https://docs.abp.io/en/abp/latest/Blob-Storing#blob-storage-providers

Hi,

You need to configure a BLOB Storage provider: https://docs.abp.io/en/abp/latest/Blob-Storing#blob-storage-providers

It is configured in the WebModule.

private void ConfigureBlobStorage(ServiceConfigurationContext context, IConfiguration configuration)
    {
        var env = context.Services.GetHostingEnvironment();

        Configure<AbpBlobStoringOptions>(options =>
        {
            options.Containers.ConfigureDefault(container =>
            {
                //use database blob storage for development convenience, use Azure in production
                if (env.IsDevelopment())
                {
                    container.UseDatabase();
                }
                else
                {
                    container.UseAzure(azure =>
                    {                        
                        azure.ConnectionString = configuration["AzureBlobProviderConfiguration:ConnectionString"];
                        azure.ContainerName = configuration["AzureBlobProviderConfiguration:ContainerName"] ?? "default";
                        azure.CreateContainerIfNotExists = bool.TryParse(configuration["AzureBlobProviderConfiguration:CreateContainerIfNotExists"], out bool createContainerIfNotExists) ? createContainerIfNotExists : true;
                    });
                }
            });
        });
    }

Hi,

It appears that it needs this configuration somewhere in tests in order to work. Where should that go?

Hi,

DbMigrator and Web are two applications, you should to configuration it in the DbMigrator project too.

DbMigrator is working without issue and is seeding data, including blob storage data, as expected.

The issue is only occurring when running the automated tests. I am specifically looking for guidance on working with blob storage from the test projects.

Hi,

Ok, so you need to configure it in the test project. for example: https://github.com/abpframework/abp/blob/dev/framework/test/Volo.Abp.BlobStoring.Azure.Tests/Volo/Abp/BlobStoring/Azure/AbpBlobStoringAzureTestModule.cs#L42

I was able to solve the issue by adding the below to my EntityFrameworkCoreTestModule: new BlobStoringDbContext( new DbContextOptionsBuilder<BlobStoringDbContext>().UseSqlite(connection).Options ).GetService<IRelationalDatabaseCreator>().CreateTables();

in the CreateDatabaseAndGetConnection method.
