UUnitTask

UnitTask's are used to implement supporting code for UnitTest's, for handling complex behind-the-scenes setup prior to test execution (e.g. primarily for implementing game-specific server/client environment setup), which is shared between many unit tests, and which is better to abstract-away from visibility in unit tests themselves, for code clarity.

Remarks

UnitTask's are used to implement supporting code for UnitTest's, for handling complex behind-the-scenes setup prior to test execution (e.g. primarily for implementing game-specific server/client environment setup), which is shared between many unit tests, and which is better to abstract-away from visibility in unit tests themselves, for code clarity.

For example, some games require authentication negotiation before the game client can connect to a server, and this is the type of task that UnitTask's are designed for.

Unit tasks that are added to a unit test, must complete execution before the unit test itself can execute.

Variables

  Type Name Description
Protected variable bool bStarted Whether or not the UnitTask has started
Protected variable UProperty TObjectPtr< UUnitTest > Owner The UnitTest that owns this task

Functions

  Type Name Description
Public function Virtual void

Attach ( UUnitTest* InOwner
)

 Attach the task to a unit test
Public function Virtual void

Cleanup ()

 Cleanup the task state, after the task completes
Public function Const EUnitTaskFlags Retrieves UnitTaskFlags
Public function bool Whether or not the task has started
Public function Virtual bool Whether or not the task has completed
Public function Virtual Const bool Must override in subclasses, that need ticking.
Public function Virtual void

NetTick ()

 Tick function that runs at a tickrate of ~60 fps, for interacting with netcode (high UnitTick tickrate, can lead to net buffer overflows)
Public function Virtual void Gives UnitTask's an opportunity to alter the MinimalClient setup parameters

ResetTimeout ( FString ResetReason,
bool bResetConnTimeout,
uint32 MinDuration
)

 See UUnitTest::ResetTimeout
Public function Virtual void Start executing the task
Public function void

TriggerFailure ( FString Reason
)

 Triggers a failure for the UnitTask and owning UnitTest
Public function Virtual void

UnitTick ( float DeltaTime
)

 Events passed from the unit test Main tick function for the unit test
Public function Virtual void After attaching to a unit test, validate the unit task settings are compatible
