# features/profile-form/04-validation.feature
 
@REQ-101
Feature: Profile Form Validation
  As a Cloud Architect
  I want the form to validate my inputs
  So that I get immediate feedback on errors
 
  Background:
    Given the architect is logged in
    And they navigate to "/profile/create"
 
  @REQ-101 @critical
  Scenario: Required fields show errors when empty
    Given the architect is on step 1 "Personal Info"
    And they have not filled in any fields
    When they click "Next"
    Then they should see "Full name is required"
    And they should see "Email is required"
    And the form should not advance to step 2
 
  @REQ-101
  Scenario: Email format is validated
    Given the architect is on step 1 "Personal Info"
    When they type "not-an-email" in the "Email" field
    And they click "Next"
    Then they should see "Please enter a valid email address"
 
  @REQ-101
  Scenario: LinkedIn URL must point to linkedin.com
    Given the architect is on step 1 "Personal Info"
    When they type "https://twitter.com/someone" in the "LinkedIn URL" field
    And they click "Next"
    Then they should see "Must be a valid LinkedIn profile URL"
 
  @REQ-102
  Scenario: Years of experience must be between 0 and 50
    Given the architect is on step 2 "Experience"
    When they type "-3" in the "Years of Experience" field
    And they click "Next"
    Then they should see "Must be between 0 and 50 years"
 
  @REQ-102
  Scenario: Job end date must be after start date
    Given the architect is on step 3 "Job History"
    When they set start date to "2025-06-01"
    And they set end date to "2024-01-01"
    And they click "Next"
    Then they should see "End date must be after start date"

# features/profile-form/08-file-uploads.feature
 
@REQ-201
Feature: File Upload Protection
  As a Cloud Architect
  I want the form to reject invalid files
  So that only safe, correct images are uploaded
 
  @REQ-201 @critical
  Scenario: Profile photo rejects oversized file
    Given the architect is on step 5 "Uploads"
    When they select a 15MB file for "Profile Photo"
    Then they should see "File must be under 5MB"
 
  @REQ-201 @critical
  Scenario: Profile photo rejects non-image files
    Given the architect is on step 5 "Uploads"
    When they select a .exe file for "Profile Photo"
    Then they should see "Only JPEG, PNG, and WebP files are accepted"
 
  @REQ-201
  Scenario: Maximum file count enforced
    Given the architect has uploaded 10 architecture diagrams
    When they try to add another file
    Then they should see "Maximum 10 files allowed"

# features/profile-form/03-multi-step.feature
 
@REQ-301
Feature: Multi-Step Navigation
  As a Cloud Architect
  I want to navigate between form steps
  So that I can fill out the form at my own pace
 
  @REQ-301 @critical
  Scenario: Completing step 1 unlocks step 2
    Given the architect fills all required fields on step 1
    When they click "Next"
    Then step 2 "Experience" should be active
    And step 1 should show a checkmark
 
  @REQ-301
  Scenario: Navigating back preserves data
    Given the architect is on step 3 "Job History"
    And they have entered "Acme Corp" as company name
    When they click "Back"
    And they click "Next"
    Then the company name field should still contain "Acme Corp"
 
  @REQ-301
  Scenario: Cannot skip ahead past invalid steps
    Given the architect is on step 1 "Personal Info"
    And the "Full Name" field is empty
    When they click step 3 in the progress indicator
    Then step 1 should remain active
