java.lang.Object
  ds.ov2.test.Check_data_transmission

 class Check_data_transmission
extends Object

Test the protocol layer by sending arguments and receiving results of varying sizes. The bytes sent and received are enumerated to detect bugs. Checks various corner cases, for instance total argument length of 509, 510 and 511 bytes.

Method Detail

check_with_sizes

public long check_with_sizes(String msg,
                             int a1,
                             int a2,
                             int a3,
                             int a4,
                             int a5,
                             int r1,
                             int r2,
                             int r3,
                             int r4,
                             int r5,
                             boolean performance_test)
                      throws CardException,
                             Data_protocol_host.Data_error

Test the protocol layer by sending 5 arguments and receiving 5 results of the specified size. Runs first the data size protocol to set the size of the Resizable_buffer's that are used as arguments and results. If performance_test is false the bytes in the transmission are enumerated to catch reordering bugs.

Parameters:

msg - identifier for progress messages

a1 - size of the first argument

a2 - size of the second argument

a3 - size of the third argument

a4 - size of the fourth argument

a5 - size of the fifth argument

r1 - size of the first result

r2 - size of the second result

r3 - size of the third result

r4 - size of the fourth result

r5 - size of the fifth result

performance_test - if true do not enumerate the bytes sent to obtain pure transmission times

Returns:

duration of the data transmission (without setting the sizes or allocating the buffers but with the protocol layer overhead) in nanoseconds

Throws:

Data_protocol_host.Data_error - if an error in the protocol layer is detected

CardException - on communication problems

run_ex

public void run_ex()
            throws CardException,
                   Data_protocol_host.Data_error

Run protocol layer checks. Check with a number of different argument and result sizes.

Throws:

Data_protocol_host.Data_error - if an error in the protocol layer is detected

CardException - on communication problems

run

public void run()

Exception wrapper for run_ex(). Run the protocol layer checks and print escaping exceptions.
