8 years ago Dataset - New Test Suite
Instanting a new Dataset
- cannot be instantiated without pageSize
- cannot be instantiated without fetch()
with default constructor values
- has default constructor values
- initializes the state
- does not fetch a page
fetching a page
- fetches a page of records
- returns a pending state
- fetches a set of empty pending records
immutable states
resolving a fetch request
- transitions to a new resolved state
- resolves records
rejecting a fetch request
- transitions to a new rejected state
- rejects records
changing the readOffset
- transitions to a new rejected state
- loads an additional page
not changing the readOffset
- does not transition to a new state
Loading Records
with setReadOffset at the start of the dataset
with less than one page loadHorizon
- requests one page of records
with less than two pages loadHorizon
- requests two pages of records
resolving all requests
- has two resolved pages
rejecting all requests
- has two rejected pages
incrementing the readOffset to the next page
- has three resolved pages
decrementing the readOffset past 0
- sets the readOffset to 0
with setReadOffset at the middle of the dataset
with less than one page loadHorizon
- initializes six page of records
- has two pending pages
with less than two pages loadHorizon
- initializes seven pages of records
- has four pending pages
incrementing the read offset to the next page before resolving any pages
- unloads a page
- has four pending pages
resolving all requests
- has four resolved pages
incrementing the readOffset to the next page
- unloads a page
- unfetches the unloaded page
- has four resolved pages
decrementing the readOffset to the prev page
- unloads a page
- has four resolved pages
Statistics
when fetch() returns totalPages
- makes one request
resolving the request with totalPages stats
- sets total pages
Setting the offset to the end of the dataset
- makes one additional request
Setting the offset past the loadHorizon boundary of the dataset
- does not make any additonal requests
- sets the readOffset at the out of bounds index
- has an unrequested state
- has an unrequested record at the readOffset
- has an unrequested empty page on the record
rejecting the request with totalPages stats
- sets the total pages
