ABP框架使用(版本3.3.1) - Test Project

1.  foreign key constraint failed

在TestDataBuilder 中已经加了IdentityUser，但测试Application的时候，还是会报错

TestDataBuilder 

        private async Task AddUsers()
        {
            var adminUser = new IdentityUser(_guidGenerator.Create(), "administrator", "admin@abp.io");
            adminUser.AddRole(_adminRole.Id);
            adminUser.AddClaim(_guidGenerator, new Claim("TestClaimType", "42"));
            await _userRepository.InsertAsync(adminUser);

        }

?

1 2 3 4 5 6 7

protected override void AfterAddApplication(IServiceCollection services) {     _currentUser = Substitute.For<ICurrentUser>();     _currentUser.Id.Returns(_testData.UserJohnId);     _currentUser.IsAuthenticated.Returns(true);     services.AddSingleton(_currentUser); }

这种方法不起作用
optionsBuilder.UseSqlite($"Filename={databaseName}", x => x.SuppressForeignKeyEnforcement());

可以在连接字符串里指定不用Foreign Keys参数
AbpIdentityEntityFrameworkCoreTestModule

?

1	var connection = new SqliteConnection("Data Source=:memory:;Foreign Keys=False");

2. 测试的application方法disable了UOW,会报错Context已经displose

                await WithUnitOfWorkAsync(async () =>
            {
...

            });

3.Substitue 其它

ISettingProvider _settingProvider = Substitute.For<ISettingProvider>();
            _settingProvider.GetOrNullAsync(Arg.Any<string>()).Returns((string) null);
_settingProvider.GetOrNullAsync(IdentitySettingNames.Password.RequiredLength).Returns(Task.FromResult("42"));
            services.Replace(ServiceDescriptor.Singleton(_settingProvider));

Substitue DomainService

    public class ItemManager : DomainService
    {
        public ItemManager()
        {

        }
        public virtual  string GetTestData()
        {
            return "GetTestData";

        }

    }

Test

        protected override void AfterAddApplication(IServiceCollection services)
        {
            _itemManager = Substitute.For<ItemManager>();
            _itemManager.GetTestData().Returns("MockData");
            services.AddTransient(provider => _itemManager);
        }

        [Fact]
        public  void Should_Get_Mock_Data()
        {
            var result = _itemManager.GetTestData();
            result.ShouldBe("MockData");
        }

 但如果DomainService有注入其它参数，就会报错

Castle.DynamicProxy.InvalidProxyConstructorArgumentsException : Can not instantiate proxy of class:Items.ItemManager.
Could not find a parameterless constructor.

    public class ItemManager : DomainService
    {
        private IRepository<Item, Guid> _repository;
        public ItemManager(IRepository<Item, Guid> repository)
        {
            _repository = repository;
        }
        public virtual  string GetTestData()
        {
            return "GetTestData";

        }

    }

GetRequiredService 获取参数会报错
System.ArgumentNullException : Value cannot be null. (Parameter 'provider')

必须将所需的参数Substitue出来传递进去

        protected override void AfterAddApplication(IServiceCollection services)
        {
            // var repository = ServiceProvider.GetRequiredService<IRepository<Item, Guid>>();
            var repository = Substitute.For<IRepository<Item, Guid>>();
            services.AddSingleton(repository);
            _itemManager = Substitute.For<ItemManager>(repository);
            _itemManager.GetTestData().Returns("MockData");
            services.AddTransient(provider => _itemManager);
        }

 

 4.判断报某种Exception

            var exception = await Assert.ThrowsAsync<UserFriendlyException>(
                async () => await _testAppService.UpdateAsync(beforeEntity.Id, testDto)
            );
            exception.Code.Contains("Unique").Should().BeTrue();

 5.NSubstitute.Exceptions.CouldNotSetReturnDueToNoLastCallException: Could not find a call to return from.

Make sure you called Returns() after calling your substitute (for example: mySub.SomeMethod().Returns(value)), and that you are not configuring other substitutes within Returns() (for example, avoid this: mySub.SomeMethod().Returns(ConfigOtherSub())).

If you substituted for a class rather than an interface, check that the call to your substitute was on a virtual/abstract member. Return values cannot be configured for non-virtual/non-abstract members.
