[nicolebudiman]

As an admin or a manager,
I should be able to create a new lease
so that I can assign occupant to the correct lease.

Acceptance Criteria
Given that I click on a particular Apartment from the Homepage and view the Apartment Profile,
When I click on Add New Lease,
Then, I will be able to enter the lease start date, end date and monthly rent of the new lease.

Given that I leave any of the fields blank,
When I try to submit,
Then, I will be able to see a warning message that a certain field is blank.

Given that the end date I entered is before or same as the start date,
When I try to submit,
Then, I will be able to see a warning message that lease end date should be after lease start date.

Given that the monthly rate I entered is negative,
When I try to submit,
Then, I will be able to see a warning message that the monthly rate should not be negative.

Given that there is an existing lease of which dates overlap with the new lease
When I try to submit any valid change,
Then I will be able to see a warning message that there is a current existing lease with overlapping dates.

As a guest,
I should not be able to add any new lease
so that the data is not added without the right authorisation

Acceptance Criteria
Given that I click on a particular Apartment from the Homepage,
When I view the Apartment Profile
Then, I should not be able to see any link to add a new lease

To confirm:

1. Does apartment status matter?
