使用rspec

Question

我使用hanami框架和rspec lib来测试我的代码和PG数据库。当我尝试测试一个动作时，我得到以下错误：

PG::InFailedSqlTransaction: ERROR:  current transaction is aborted, commands ignored until end of transaction block

我的操作已包含在存储库事务中：

  def call(params, dependencies)
    begin
      dependencies.repository.transaction do
        create_user(params, dependencies)
        assign_tags(params, dependencies)
        assign_notes(params, dependencies)
      end
    rescue Hanami::Model::Error, Domain::Errors::Exception => error
      raise Domain::Errors::CreateUserFailed, error.message
    end
  end

在这里你可以看到我的部分测试失败了：

it 'should raise exception if params contains duplicated email' do
expect{service.call(duplicated_email)}
  .to raise_exception(Domain::Errors::CreateUserFailed)
  .with_message('Duplicated values found (id or 
  email)')
end

it 'should raise exception if params contains duplicated note id' do
expect{service.call(duplicated_note_id)}
  .to raise_exception(Domain::Errors::CreateUserFailed)
end

第一次测试通过，但第二次测试通过了前面提到的异常。我知道这是因为先前的测试在事务块中引发了异常。我找到了这个answer中提到的解决方案，但我不适用于我的情况。

RSpec.configure do |config|
  config.before(:suite) do
   DatabaseCleaner.clean_with :deletion
  end

  config.before(:each) do
   DatabaseCleaner.strategy = :transaction
  end

  config.before(:each) do
   DatabaseCleaner.start
  end

  config.after(:each) do
   DatabaseCleaner.clean
  end
end

感谢所有答案：）

编辑：

 Failure/Error:
   expect{service.call(duplicated_note_id)}
     .to raise_exception(Domain::Errors::CreateUserFailed)
     .with_message('Duplicated values found in user notes (id)')
