[MAGETWO-1802] Import of file with spaces in required attributes is allowed

[piotrekkaminski]

In case empty values (spaces) are specified for required attributes in import file (example: first name and last name), there is no validation error and import is done successfully. Though it's not possible to create a customer with empty first name and last name via admin interface.

Test data

email	_website	firstname	group_id	lastname
test_ifebgl@unknown-domain.com	base		1

Preconditions

1. Version 2.0

Steps to reproduce

1. Open Backend -> System -> Import/Export -> Import
2. Select Entity Type: Customers
3. Select Import Behaviour: Append Complex Data
4. Select Import Format Version: Magento 1.7 format
5. Select test file
6. Click Check Data button.

Expected result

validation error, messages "Required attribute 'firstname' has an empty value in rows: 1" and "Required attribute 'lastname' has an empty value in rows: 1" are shown

Actual result

validation successful, message "File is valid! To start import process press "Import" button" is shown

Note

The same issue exists for Magento 2.0 import format
