README

Siatest

The siatest package is designed to handle the integration tests for the Sia codebase.

Methodology

When writing siatests, the developer should structure the tests to mimic production use. All interactions with Sia should be performed through the API and client methods.

Test group creation is a time and resource intensive operation. Whenever possible tests should be grouped together and share the same test group.

Submodules

There is a submodule of the siatest package for each module of Sia (ie Host, Renter, Wallet, etc). There submodules contain all the test code for the corresponding Sia module.

In addition to these testing submodules there is a dependencies submodule. The dependencies submodule is for dependency injection for tests that need to exploit a specific test scenario that cannot be reliably tested through normal means.

Subsystems

The following subsystems help the SiaDir module execute its responsibilities:

Local Dir Subsystem

Key Files

The Local Dir subsystem is responsible for representing a local directory on disk that could be uploaded to the Sia network.

Exports TestNode Methods

  • NewLocalDir creates a new LocalDir in the TestNodes renter directory

LocalDir Methods

  • CreateDircreates a new LocalDir
  • Files returns a slice of files that are in the LocalDir
  • Name returns the name of the LocalDir
  • NewFile creates a new LocalFile in the LocalDir
  • NewFileWithName creates a new LocalFile with a specified name in the LocalDir
  • NewFileWithMode creates a new LocalFile with a specified mode in the LocalDir
  • Path returns the path of the LocalDir
  • PopulateDir populates a LocalDir with files and sub-directories

Outbound Complexities

  • NewLocalDir calls out to the testhelper subsystem's RenterDir method
Local File Subsystem

Key Files

The Local File subsystem is responsible for representing a file on disk that has been uploaded to the Sia network.

Exports

  • Data returns the byte slice data of a file
  • Delete deletes the local file from disk
  • Equal compares a byte slice to the data stored on disk
  • FileName returns the file name
  • Move moves the file to a new random location
  • Path returns the on disk path to the file
  • Size returns the size of the file
  • Stat is a wrapper for os.Stat
Remote Dir Subsystem

Key Files

The Remote Dir subsystem is responsible for representing a directory on the Sia network.

Exports

  • SiaPath returns the siapath of the remote directory
Remote File Subsystem

Key Files

The Remote File subsystem is responsible for representing a SiaFile on the Sia network.

Exports

  • Checksum returns the checksum of the remote file
  • SiaPath returns the siapath of the remote file
Test Group Subsystem

Key Files

The Test Group subsystem to responsible for creating a group of TestNodes to form a mini Sia network.

There is a testGroupBuffer that is used to control the creation of the TestGroups in order to reduce too many open file errors.

Exports

  • NewGroup creates a new TestGroup with fully synced, funded, and connected TestNodes based on node params
  • NewGroupBuffer creates a buffer channel and fills it
  • NewGroupFromTemplate creates a new TestGroup with fully synced, funded, and connected TestNodes based on group params
  • AddNodeN adds a number of nodes of a given template to a TestGroup
  • AddNodes adds a list of nodes to a TestGroup
  • Close closes the group
  • Hosts converts the map of host nodes to a slice and returns it
  • Nodes converts the map of nodes to a slice and returns it
  • Miners converts the map of miners nodes to a slice and returns it - RemoveNode removes a node from the group
  • Renters converts the map of renters nodes to a slice and returns it
  • RestartNode restarts a node from the group
  • SetRenterAllowance sets the allowance of a renter node in the group
  • StartNode starts a group's previously stopped node
  • StartNodeCleanDeps starts a group's previously stopped node with nil dependencies
  • StopNode stops a group's node
  • Sync makes sure that the group's nodes are synchronized

Inbound Complexities

Outbound Complexities

Test Node Subsystem

Key Files

The Test Node subsystem is responsible for representing a node on the Sia network.

Exports

  • NewNode returns a new TestNode that has a funded wallet
  • NewCleanNew returns a new TestNode that has an unfunded wallet
  • NewCleanNewAsync returns a new TestNode that has an unfunded wallet and uses the NewAsync function of the server package
  • IsAlertRegistered checks if an alert is registered with a TestNode
  • IsAlertUnregistered checks if an alert has been unregistered with a TestNode
  • PrintDebugInfo logs out some helpful debug information about a TestNode
  • RestartNode stops and then restarts a TestNode
  • SiaPath returns a siapath of a LocalDir or LocalFile that could be used for uploading
  • StartNode starts a TestNode
  • StartNodeCleanDeps starts a TestNode but first sets any dependencies to nil
  • StopNode stops a TestNode
Test Helpers Subsystem

Key Files

The Test Helper subsystem contains helper methods and functions for executing tests.

Exports

  • ChunkSize calculates the size of a chunk based on the pieces
  • DownloadDir returns the LocalDir of the TestNode that represents the downloads directory
  • FilesDir returns the LocalDir of the TestNode that represents the upload directory
  • Fuzz returns -1, 0, or 1
  • RenterDir returns the path of the TestNode's renter directory
  • RenterFilesDir returns the path of the TestNode's files directory
  • Retry calls a function a number of times with a sleep duration in between each call
  • TestDir creates a tmp directory on disk for the test

Inbound Complexities

  • The LocaDir subsystem's NewLocalDir method uses the RenterDir method
Modules Subsystem

Key Files

The modules subsystem contains useful methods that are common across a module's test suite. For example, uploading a file is necessary for almost every renter test so there are a number of Upload methods in renter.go that can be used to deduplicate code.

See each corresponding module file for more details and examples.
