Class SshdServerMock

java.lang.Object
  com.sonyericsson.hudson.plugins.gerrit.trigger.test.SshdServerMock

All Implemented Interfaces:

org.apache.sshd.server.CommandFactory

public class SshdServerMock
extends Object
implements org.apache.sshd.server.CommandFactory

The beginning of a mock of a sshd server. When it is done the idea is to use this to send in stream-events over the ssh connection, and make connection related tests without running Gerrit on the local machine. There is some progress but most of the predefined command types has issues.

Constructor Detail

SshdServerMock

public SshdServerMock()

Method Detail

createCommand

public org.apache.sshd.server.Command createCommand(String s)

Specified by:

createCommand in interface org.apache.sshd.server.CommandFactory

setCurrentCommand

protected SshdServerMock.CommandMock setCurrentCommand(SshdServerMock.CommandMock command)

Sets the current command being executed and adds it to the commandHistory.

Parameters:

command - the command.

Returns:

the command.

getCurrentCommand

public SshdServerMock.CommandMock getCurrentCommand()

The last started command. There could be other commands running in parallel.

Returns:

the current command.

getRunningCommand

public SshdServerMock.CommandMock getRunningCommand(String commandSearch)

Gets the first running command that matches the given regular expression.

Parameters:

commandSearch - the regular expression to match.

Returns:

the found command or null.

returnCommandFor

public void returnCommandFor(String commandPattern,
                             Class<? extends SshdServerMock.CommandMock> cmd)
                      throws NoSuchMethodException

Specifies a command type to instantiate and give to mina when a command matching the given regular expression is wanted.

Parameters:

commandPattern - the regular expression

cmd - the class to create the command from. The class must have a constructor taking a single String argument which is the command requested.

Throws:

NoSuchMethodException - if there is no matching constructor.

returnCommandFor

public void returnCommandFor(String commandPattern,
                             Class<? extends SshdServerMock.CommandMock> cmd,
                             Object[] arguments,
                             Class<?>[] types)
                      throws NoSuchMethodException

Specifies a command type to instantiate and give to mina when a command matching the given regular expression is wanted.

Parameters:

commandPattern - the regular expression

cmd - the class to create the command from. The class must have a constructor where the first argument is a String followed by the class types provided by the types parameter.

arguments - the other arguments to the constructor besides the command.

types - the other class types to match the constructor against.

Throws:

NoSuchMethodException - if there is no matching constructor.

returnCommandFor

public void returnCommandFor(String commandPattern,
                             Class<? extends SshdServerMock.CommandMock> cmd,

Specifies a command type to instantiate and give to mina when a command matching the given regular expression is wanted.

Parameters:

commandPattern - the regular expression

cmd - the class to create the command from. The class must have a constructor where the first argument is a String followed by the class types provided by the types parameter.

oneShot - if this command should only be returned the first time it is called for.
