How to send data to Serial Port in Qt Test

egbiomated

I am trying to write some integration tests around my serial device and it appears that i can't send data in my tests i get the following error message:

QWARN  : Test::test_case3() QObject::startTimer: Timers can only be used with threads started with QThread

My Test case:

void Test::test_case3()
{
    // MotorTest mt;
    // QThread* thread = new QThread( );
    // mt.moveToThread(thread);
    // thread->start();

    qDebug("MOTOR TESTS");
    Motor motor;
    // // QThread::sleep(1);
    QTest::qSleep(1000);
    motor.motor_jog_accel(10);
    // / QTest::qSleep(1000);
    motor.motor_jog_decel(10);
    // // QTest::qSleep(1000);
    motor.motor_jog_speed(10);
    // // QTest::qSleep(1000);
    motor.motor_jog_enable();
    // // QTest::qSleep(5000);
    motor.motor_jog_disable();
    // // QTest::qSleep(1000);
}

Here is some of the Code from the motor that is relevant:

#include "motor.h"
#include <string.h>
#include <QIODevice>
#include <QDebug>

Motor::Motor()
{
    sp.setPortName("COM1");
    sp.open(QIODevice::ReadWrite);
}

// void Motor::motor_send_command(char buff[], uint16_t buffLen)
void Motor::motor_send_command(char buff[], uint16_t buffLen)
{
    qDebug() << "SENDING: " << buff;
    char cbuff[50] = { '\0' };
    strncpy(cbuff, buff, 50);
    snprintf(cbuff, 50, "%s\r", buff);
    sp.write(cbuff);
}

void Motor::motor_send_command(char buff[])
{
    qDebug() << "SENDING: " << buff;
    char cbuff[50] = { '\0' };
    strncpy(cbuff, buff, 50);
    snprintf(cbuff, 50, "%s\r", buff);
    qDebug() << "ABOUT: " << buff;
    sp.write(cbuff);
    qDebug() << "SENT: " << buff;
}

void Motor::motor_set_accel(uint16_t accel)
{
}

void Motor::motor_set_accel_max(uint16_t accel)
{

}

void Motor::motor_start_jog()
{

}

void Motor::motor_change_speed(uint16_t speed)
{

}

void Motor::motor_set_decel(uint16_t decel)
{

}

void Motor::motor_jog_accel(uint16_t accel)
{
    motor_send_command("JA1000");
}

void Motor::motor_jog_velocity(uint16_t velocity)
{

}

void Motor::motor_jog_disable()
{
    motor_send_command("SJ");
}

void Motor::motor_jog_enable()
{
    motor_send_command("CJ");
}

void Motor::motor_jog_decel(uint16_t decel)
{
    motor_send_command("JL1000");
}

void Motor::motor_jog_speed(uint16_t speed)
{
    motor_send_command("JS1");
}

void Motor::motor_disable()
{

}

void Motor::motor_enable()
{

}

void Motor::motor_microstep_resolution(uint16_t resolution)
{

}

void Motor::motor_set_direction(uint8_t direction)
{

}

void Motor::motor_stop_jogging()
{

}

void Motor::motor_velocity_max(uint16_t vmax)
{

}

Is there any way to be able to start the main test with QThread? I guess the interrupts used for the serialport are not able to start because of that?

Hi,

Are you using QTEST_MAIN for your tests ?
