Variables

  Type Name Description
Public variable TSharedPtr< SWindow > AbortAllDialog The 'abort all' dialog
Public variable UProperty TArray< TObjectPtr< UUnitTest > > ActiveUnitTests Holds a list of currently active unit tests
Public variable UProperty Config uint8 AutoCloseMemoryPercent As above, but when reaching this limit, recently started unit test(s) will be terminated/re-queued, to get back within limits
Public variable bool bAbortedFirstRunUnitTest If a unit test was aborted on its first run, strictly cap all first-run unit tests to one at a time
Public variable bool bAllowRequeuingUnitTests Whether or not to allow re-queuing of unit tests
Public variable UProperty Config bool bCapUnitTestCount Whether or not to cap the maximum number of unit tests that can be active at any given time
Public variable UProperty Config bool bCapUnitTestMemory Whether or not to cap active unit tests, based on memory usage
Public variable UProperty TArray< TObjectPtr< UUnitTest > > FinishedUnitTests Unit tests which are finished, and are kept around until printing the final summary
Public variable UProperty Config uint8 MaxAutoCloseCount Limits the number of auto-aborts a particular unit test will allow, before it is no longer accepted for re-queueing
Public variable UProperty Config uint8 MaxMemoryPercent When total physical memory usage, as a percentage, reaches this limit, no new unit tests can be started
Public variable UProperty Config uint8 MaxUnitTestCount Specifies the maximum number of unit tests that can be run at any given time
Public variable UProperty TArray< TObjectPtr< UClass > > PendingUnitTests Holds a list of unit tests pending execution
Public variable TUniquePtr< FOutputDeviceFile > StatusLog The log file for outputting overall unit test status
Public variable TSharedPtr< SLogWindow > StatusWindow The log window which displays the overall status of unit testing
Public variable UProperty Config uint32 UnitTestSessionCount The number of recorded sessions where UE has run unit tests (max one per each run of the UE process)

Constructors

  Type Name Description
Public function  

UUnitTestManager ( const FObjectInitializer& ObjectInitializer
)

 UUnitTestManager

Destructors

  Type Name Description
Public function Virtual   Destructor for handling removal of log registration

Functions

  Type Name Description
Public function void

DumpStatus ( bool bForce
)

 Dumps status information for running/pending unit tests, to the status window and log
Public function bool

Exec ( UWorld* InWorld,
const TCHAR* Cmd,
FOutputDevice& Ar
)

 Handles exec commands starting with 'UnitTest'
Public function Static UUnitTestManager *

Get ()

 Static getter for the unit test manager
Public function const FString Returns the base log directory used by unit tests
Public function Static FSlateColor  
Public function void Initialize the unit test manager
Public function void Initialize unit test log output
Public function bool Returns whether or not there are unit tests running (or about to be run)
Public function void

NotifyCloseAllDialogResult ( const TSharedRef< SWindow >& DialogWindow,
EAppReturnType::Type Result,
bool bNoResult
)

 When the main status window is closed, a dialog pops up asking if you want to abort all running unit tests; this returns the result
Public function void

NotifyCloseDialogResult ( const TSharedRef< SWindow >& DialogWindow,
EAppReturnType::Type Result,
bool bNoResult
)

 When a log window is closed, a dialog pops up asking if the unit test should be aborted - this returns the result NOTE: This dialog is non-modal, i.e. doesn't block the game thread - so the unit test is not guaranteed to still exist
Public function void

NotifyLogWindowClosed ( const TSharedRef< SWindow >& ClosedWindow
)

 Notifies when a log window has closed
Public function void Notification that is triggered when a unit test is cleaning up
Public function void

NotifyUnitTestComplete ( UUnitTest* InUnitTest,
bool bAborted
)

 Notification that is triggered when a unit test completes
Public function void Opens the status log window
Public function void Opens the log window, for a unit test
Public function void Checks to see if we're ready to execute any unit tests in the queue, and if so, begins execution
Public function void Prints the final unit test summary, when all active/pending unit tests have completed
Public function void

PrintUnitTestResult ( UUnitTest* InUnitTest,
bool bFinalSummary,
bool bUnfinished
)

 Prints the results information for a single unit test
Public function bool

QueueUnitTest ( UClass* UnitTestClass,
bool bRequeued
)

 Queues a unit test for execution
Public function Virtual void

Serialize ( const TCHAR* Data,
ELogVerbosity::Type Verbosity,
const FName& Category
)

 We're hiding UObject::Serialize() by declaring this. That's OK, but Clang will warn about it.
Public function void

SetStatusColor ( FSlateColor InStatusColor
)

  
Public function void

SetStatusLog ( bool bInStatusLog
)

 Getters/Setters
Public function bool

WithinUnitTestLimits ( UClass* PendingUnitTest
)

 Tests whether currently active unit tests, and optionally/additionally, a unit test about to be executed, fall within limits/restrictions on unit test counts and memory usage

Overridden from FTickableGameObject

  Type Name Description
Public function Virtual Const bool Used to determine if an object should be ticked when the game is paused.

Overridden from FTickableObjectBase

  Type Name Description
Public function Virtual Const TStatId Return the stat id to use for this tickable
Public function Virtual Const bool Must override in subclasses, that need ticking.
Public function Virtual void

Tick ( float DeltaTime
)
