Method Detail

execCommand

public static String[] execCommand(String command,
                                   boolean haltOnCommandFailure)

Execute the given command either in this member or a remote member depending on the value of CliHelperPrms.executeRemote.

Parameters:

command - The command to execute.

haltOnCommandFailure - If false, then allow the method to fail when the command fails. if true, then expect the method to succeed when, for example, the test gave the command bad arguments intentionally.

Returns:

[0] The TestableShell.getOutputText() result of the command. [1] The presentation string (the output text of the command that is presented to the user).

execCommandLocally

public static String[] execCommandLocally(String command,
                                          boolean haltOnCommandFailure)

Execute the given command in this member

Parameters:

command - The command to execute.

haltOnCommandFailure - If false, then allow the method to fail when the command fails. if true, then expect the method to succeed when, for example, the test gave the command bad arguments intentionally.

Returns:

[0] The TestableShell.getOutputText() result of the command. [1] The presentation string (the output text of the command that is presented to the user).

execCommandOnRemoteCli

public static String[] execCommandOnRemoteCli(String command,
                                              boolean haltOnCommandFailure)

Execute the given command in another member running gfsh. The other member must be checking the blackboard to know to execute the command. This method ensures that only one command will be run at a time even if it is called concurrently.

Parameters:

command - The command to execute.

haltOnCommandFailure - If false, then allow the method to fail when the command fails. if true, then expect the method to succeed when, for example, the test gave the command bad arguments intentionally.

Returns:

[0] The TestableShell.getOutputText() result of the command. [1] The presentation string (the output text of the command that is presented to the user).

HydraTask_execCommandFromBB

public static void HydraTask_execCommandFromBB()

Execute a command in this member running gfsh. The command is on the blackboard. This can be called repeatedly to poll for a command waiting to execute.
