• Steps to reproduce the issue:

Suppose we are trying to create a unit/integration test for a method in an application service layer equipped with a [RequiresFeature] attribute

[RequiresFeature(MyFeatures.MyAwesomeNewFeature)]
public virtual async Task< ItemsDto > GetListOfItemsAsync()
{
	return new ItemsDto
	{
		....
	};
}

Already in the ApplicationTestModule module with the AddAlwaysAllowAuthorization() extension all Permissions are being bypassed. But how can we bypass feature requirement for test purposes ?

public class IMyApplicationTestModule : AbpModule
{
    public override void ConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.AddAlwaysAllowAuthorization();
        ....
    }
}

I tried to mock IFeatureChecker like in following example. But it broke all other unit test under MyAppService_Tests

    public class MyAppService_Tests : IMyApplicationTestBase
    {
        private readonly IMyAppService _iMyAppService;
        private readonly MyOptions _myOptions;
        private readonly ISettingProvider _settingProvider;

        private IFeatureChecker _featureChecker;

        public IMyAppService_Tests()
        {
            _iMyAppService = GetRequiredService< IMyAppService >();
            _myOptions = GetRequiredService< IOptions < MyOptions > >().Value;
            _settingProvider = GetRequiredService< ISettingProvider >();
        }

        protected override void AfterAddApplication(IServiceCollection services)
        {
            _featureChecker = Substitute.For< IFeatureChecker >();
            _featureChecker.IsEnabledAsync(MyFeatures.MyAwesomeNewFeature).Returns(Task.FromResult(true));
            services.AddSingleton(_featureChecker);
        }
        

        [Fact]
        public async Task GetListOfItems_Should_Return_IItemsDto()
        {
            // Arrange
            ....
            // Act
            var result = await _iMyAppService.GetListOfItemsAsync();

            // Assert
            result.ShouldNotBeNull();
        }}

This usage going to throw following exeception ex;

Volo.Abp.AbpInitializationException : An error occurred during the initialize Volo.Abp.Modularity.OnApplicationInitializationModuleLifecycleContributor phase of the module MyCompany.MyTag.MyApp.IdentityTestBaseModule, MyCompany.MyTag.MyApp.TestBase, Version=0.1.0.0, Culture=neutral, PublicKeyToken=null: The input string '' was not in a correct format..
