Method Detail

setInstrumentation

public void setInstrumentation(boolean instrumentation)

getInputParameters

public abstract String[] getInputParameters()

Returns:

the input parameters with which the system under test should be started

getJVMParameters

public abstract String[] getJVMParameters()

Returns:

the JVM parameters (eg -X and -D) with which the system under test should be started

getBaseURL

public abstract String getBaseURL()

Returns:

the base URL of the running SUT, eg "http://localhost:8080". Note: this value will likely depend on how getInputParameters() has been implemented

getPathToExecutableJar

public abstract String getPathToExecutableJar()

Returns:

a String representing either a relative or absolute path to the where the JAR of the system under test is located

getLogMessageOfInitializedServer

public abstract String getLogMessageOfInitializedServer()

Returns:

a string subtext that should be present in the logs (std output) of the system under test to check if the server is up and ready.

getMaxAwaitForInitializationInSeconds

public abstract long getMaxAwaitForInitializationInSeconds()

How long (in seconds) we should wait at most to check if SUT is ready and initialized (this related to the getLogMessageOfInitializedServer() method)

Returns:

preStart

public abstract void preStart()

If the SUT needs some third-party processes (eg a non-embedded database), here they can be configured and started. This method is going to be called before we start the SUT.

postStart

public abstract void postStart()

This method is going to be called after the SUT is started.

preStop

public abstract void preStop()

This method is going to be called before the SUT is stopped.

postStop

public abstract void postStop()

If the SUT needs some third-party processes (eg a non-embedded database), here we can shut them down once the SUT has been stopped.

startSut

public String startSut()

Description copied from interface: SutHandler

Start a new instance of the SUT.
This method must be blocking until the SUT is initialized.

Returns:

the base URL of the running SUT, eg "http://localhost:8080"

isSutRunning

public boolean isSutRunning()

Description copied from class: SutController

Check if the system under test (SUT) is running and fully initialized

Specified by:

isSutRunning in class SutController

Returns:

stopSut

public void stopSut()

Description copied from interface: SutHandler

Stop the SUT

isInstrumentationActivated

public final boolean isInstrumentationActivated()

Description copied from class: SutController

Check if bytecode instrumentation is on.

Specified by:

isInstrumentationActivated in class SutController

Returns:

newSearch

public final void newSearch()

Description copied from class: SutController

Re-initialize all internal data to enable a completely new search phase which should be independent from previous ones

Specified by:

newSearch in class SutController

newTestSpecificHandler

public final void newTestSpecificHandler()

Specified by:

newTestSpecificHandler in class SutController

getTargetInfos

public final List<TargetInfo> getTargetInfos(Collection<Integer> ids)

Specified by:

getTargetInfos in class SutController

getAdditionalInfoList

public final List<AdditionalInfo> getAdditionalInfoList()

Description copied from class: SutController

Get additional info for each action in the test. The list is ordered based on the action index.

Specified by:

getAdditionalInfoList in class SutController

newActionSpecificHandler

public final void newActionSpecificHandler(int actionIndex)

Specified by:

newActionSpecificHandler in class SutController

startExternalProcessPrinter

protected void startExternalProcessPrinter()
