    • constantAndVariableDefinitionDelayedCallbackInvocations

      protected Queue<org.eclipse.xtext.util.Pair<String,Runnable>> constantAndVariableDefinitionDelayedCallbackInvocations
      This list is used to collect invocations to callbacks during a parallel constant/variable definition phase. Callbacks are not expected to be thread-safe, so we need to synchronize those calls anyway, and we want to have them in deterministic order, so we have to sort them by the variable/constant name.

      The existence of this queue defines that all callback invocations should be delayed. If it does not exist, immediate invocation is necessary.
    • MY_FORK_NAME

      protected static final String MY_FORK_NAME
      If this JVM instance is executing a fork, the name is stored here.
    • FORK_STARTUP_RETRYCOUNT_PROPERTY

      protected static final int FORK_CONNECTION_TIMEOUT_DEFAULT
      The default fork connection timeout, in seconds.
      See Also:
    • FORK_SINGLE_CONNECT_TIMEOUT_PROPERTY

      protected static final String FORK_SINGLE_CONNECT_TIMEOUT_PROPERTY

      See Also:
    • FORK_SINGLE_CONNECT_TIMEOUT_DEFAULT

      protected static final int FORK_SINGLE_CONNECT_TIMEOUT_DEFAULT
      The timeout in milliseconds used for a single connection attempt to a fork. If this timeout is hit, but the total timeout for connecting is not yet over, another attempt is being started.
      See Also:
    • FORK_CONNECT_DELAY

      protected static final int FORK_CONNECT_DELAY
      The delay until connection attempts are made to a newly started fork.
      See Also:
    • FORK_PAUSE_WAIT_INTERVAL

      protected static final int FORK_PAUSE_WAIT_INTERVAL

      The system property that allows to override the single connect timeout used when connecting to forks.
      See Also:
    • CHILD_PROCESS_KILL_TIMEOUT_DEFAULT

      protected static final int CHILD_PROCESS_KILL_TIMEOUT_DEFAULT
      The default time to wait for child processes to be killed.
      See Also:
    • forkInExecution

      protected ForkDefinition forkInExecution
      The fork that is currently being executed. This is set regardless of whether we are a fork ourselves and are currently executing our own stuff, or whether we are a master or different fork and skipping over a bunch of invocations due to them being executed by another fork.
    • variantInExecution

      protected VariantDefinition variantInExecution
      The currently executed test variant.
    • setupSuitesExecuted

      protected Map<ForkDefinition,Set<SuiteDefinition>> setupSuitesExecuted
      The setup suites that have been executed.
    • singleRunSuitesExecuted

      protected Set<SuiteDefinition> singleRunSuitesExecuted
      The single-run suites that have already been executed.
    • abortExecutionCause

      protected ExceptionWrapper abortExecutionCause
      In case of an AbortExecutionException aborting the test execution, this exception is stored here (actually, only the message and stack trace string are stored - this is because the data could just as well come from a fork, in which case an exception can not be transported over the remoting connection).
    • lastSuiteForFork

      protected Map<ForkDefinition,Integer> lastSuiteForFork
      Maps each ForkDefinition to the suite call and a number that counts any suite invocations. The fork should die after this number of suites has executed. Since suite invocation numbers are predeterminable in the dry run and deterministic, this can be used to find out whether a suite during the test run has been the last one to run on a particular fork. During this real test run, the counter is decremented on each suite invocation on a fork, so in the end, we know when the fork has finished execution (= counter reaches zero).

      This map is only used by the master to keep track of when the forks should die. It will then wait until they do. The forks still carry the responsibility to terminate their execution in a clean way!
    • numberOfSuiteInvocationsLeftOnThisFork

      protected int numberOfSuiteInvocationsLeftOnThisFork
      This counts the number of suite invocations ttill to be done on this fork. Is only used if this test runner is indeed a fork (otherwise this value has no meaning). Is somewhat related to lastSuiteForFork in that this is the individual number of invocations on a fork that is left; it is initially seeded with the corresponding lastSuiteForFork value from the master process and then counted down to know when a fork can take the quick path to termination. Basically this is an optimization to allow for quicker termination on forks that would otherwise have a huge bunch of test scripts to run through in dry mode when they're finished.
    • timeSyncResult

      protected TimeSyncResultMessage timeSyncResult
      The result of a time sync request from this fork sent to a master is stored here.
    • timeSyncResultSyncObject

      aCallback - the callback to use to report test results
      aResultLocale - the locale to be used for the test result generation (if not provided, use the non-localized default strings, which usually are in English)
      aRemotingPort - the port on which the remoting server should listen, or null if remoting should be disabled
      aRemotingBindHost - the host name (or IP) to which the remoting server should bind
      aRandomSeed - the seed for the RandomNumberOperation (optional; randomly determined if not given).
      someCommandLineArguments - all command line arguments as given to the original Java programs' main routine (required for forking!)
      Throws:
      IOException - if the remoting server startup fails, or if the connection from the master process does not complete in time (for forks only)
    • performRemotingBinding

      protected void performRemotingBinding(Integer aRemotingPort, String aRemotingBindHost) throws IOException
      Performs the remoting port binding.

    • waitForSetListInjection

      protected void waitForSetListInjection() throws IOException
      If this is a fork, we now need to wait for the setlist and test scripts to be injected by the master! Otherwise this method returns immediately.
      Throws:
      IOException
    • shutdown

      public void shutdown(boolean anEmptyRemotingOutputQueueFlag)
      Shuts down this test runner instance.
      Specified by:
      shutdown in interface TestRunner
      Parameters:
      anEmptyRemotingOutputQueueFlag - true if the remoting server shall be given time to send all remaining messages to clients while closing connections
    • run

      public SuiteSummaryResult run(SuiteDefinition aRootSuite, VariantDefinition aVariant, boolean aBlockForRemotingFlag)
      Description copied from interface: TestRunner
      Executes a specified suite. Designated starting point for test execution.
      Specified by:
      run in interface TestRunner
      Parameters:
      aRootSuite - the suite to execute
      aBlockForRemotingFlag - whether execution should pause before actually starting until execution is resumed via remoting
      Returns:
      the suite execution result (this may also be null in case there is no tangible "result", like when the test runner is actually just running the part of a single fork within a bigger test suite - the partial result in this case is not relevant, but is automatically integrated in the result of the master process)
    • run

      protected SuiteSummaryResult run(Suite aRootSuiteCall, VariantDefinition aVariant, boolean aBlockForRemotingFlag)
      Executes a specific suite call. Internal starting point for test execution.
      Parameters:
      aRootSuiteCall - the suite call to execute
      aBlockForRemotingFlag - whether execution should pause before actually starting until execution is resumed via remoting
      Returns:
      the suite execution result
    • handlePossibleAbortException

      protected void handlePossibleAbortException(Throwable anException)

      Parameters:
      anException -
    • checkForAbortion

      protected boolean checkForAbortion()
      Checks whether a situation demanding for a quick test run abortion has occurred. This is true if either an AbortExecutionException has been thrown (locally or by a fork) or if we are a fork and our last suite has executed. This method does NOT only check something, but also ensures that the setListCallback is also removed from the current callback hierarchy - a very important step, since after this method has returned true for the first time, a different execution path than normally is expected, which would cause the set list callback to throw an inconsistency exception.
      Returns:
      true if the test execution shall take the quick path to an end

    • removeBreakpoint

      protected void removeBreakpoint(int anEntryReference)
      Removes a specific breakpoint.
      Parameters:

    • createBreakpoint

      protected void createBreakpoint(int anEntryReference)
      Creates a new breapoint.
      Parameters:
      anEntryReference - the setlist entry reference at which the breakpoint will be created
    • distributeTimeSyncRequest

      protected TimeSyncResultMessage distributeTimeSyncRequest(Date aStartTime, List<org.eclipse.xtext.util.Pair<Long,TemporalUnit>> aDiffTime, BigDecimal aProgressionFactor, String[] someTargetedForks)
      This will be called when a master process either receives a time sync message from one of its forks and has to redistribute it to all the forks that this time sync is intended for, or when a master process encounters a time sync command by itself. In both cases it may have to execute it for itself. This method ONLY runs on the master! It calculates the actual internal state variables necessary for the test time proxies running in the individual fork processes and forwards those to the forks (and to the master itself), where these state variable values are then being used to call the TestTimeAdapter.

      The method is also responsible for collecting the responses about successful or failed timesyncs and for aggregating them into a result object. It blocks until this has finished (or a timeout has hit).
      Parameters:
      aStartTime - the time to set to (if null, use current system time)
      aDiffTime - the time difference in case of relative timesetting (if used, start time is ignored, because relative time setting always works with the previously-set fake test time as basis)
      aProgressionFactor -
      someTargetedForks -
      Returns:
      null if nothing went wrong, an exception wrapper containing all messages and all exceptions (textually merged) in case of (non-critical) errors
    • distributeTimeSyncRequestAsync

      protected void distributeTimeSyncRequestAsync(Date aStartTime, List<org.eclipse.xtext.util.Pair<Long,TemporalUnit>> aDiffTime, BigDecimal aProgressionFactor, String[] someTargetedForks, Fork aResultTarget)
      Like
      invalid reference
      #distributeTimeSyncRequest(Date, BigDecimal, String[])
      , but performs the work in an asynchronous thread, so it returns instantly. The result of the operation is sent to the provided fork that shall receive it.
      Parameters:
      aStartTime -
      aDiffTime -
      aProgressionFactor -
      someTargetedForks -
    • setTestTimeGuarded

      protected TimeSyncResultMessage setTestTimeGuarded(long aRealtimeOffset, long aRealtimeDecouplingTime, double aProgressionFactor)
      Performs a guarded call to the TestTimeAdapter. If the call runs into any exception, it will be caught and returned.
      Parameters:
      aProgressionFactor -
      aStartTime -
      Returns:
      null in case of success or an exception wrapper with errors in case of errors
    • isFork

      public static boolean isFork()
      Determines whether this JVM is a forked JVM from a master Integrity process.
      Returns:
    • createFork

      protected Fork createFork(Suite aSuiteCall) throws ForkException
      Creates a new fork instance. This starts up the forked JVM and connects to it for remote control.
      Parameters:
      aSuiteCall - the suite call that shall be run on the fork
      Returns:
      the new fork
      Throws:
      ForkException - if any problem arises during forking

    • resetWaitBeforeNextStep

      protected void resetWaitBeforeNextStep()
      Resets a scheduled interruption (see scheduleWaitBeforeNextStep()).
    • checkForValidationError

      protected void checkForValidationError(org.eclipse.emf.ecore.EObject anObject)
      Checks and ensures that the specified object has no validation errors.

    • timesetTraceLog

      protected void timesetTraceLog(String anAction, String aLogMessage, Date aStartDate, List<org.eclipse.xtext.util.Pair<Long,TemporalUnit>> aDiffTime, BigDecimal aProgressionFactor, String[] someTargetedForks)
      Outputs a timeset trace log. Although this checks for isTimesetTracingEnabled, the caller may also check to save some cycles when generating expensive parameters.
      Parameters:
      anAction - the action
      aLogMessage - the message to log
    • timesetTraceLog

      protected void timesetTraceLog(String anAction, String aLogMessage)
