How to check whether SPI working or not?

Question

I am totally new to Raspberry Pi. I am trying to simulate a sensor with raspberry pi where my -

Devices

Sensor:       ANALOG DVICES ADIS16227-CMLZ iSensor (ADIS1622x/PCBZ) 
Device:       Raspberry Pi 3 Model B v1.2 (Broadcom BCM2837|FBG)

Pin connection

Pin No        Specification
----------------------------
17            VDD
19            MOSI
20            GND
21            MISO
23            SCLK
24            CE0

Current output

spi mode: 0
bits per word: 8
max speed: 500000 Hz (500 KHz)

My SD card has broken and add new SD card with Raspbian as Linux raspberrypi 4.9.36-v7+ #1015 SMP Thu Jul 6 16:14:20 BST 2017 armv71 GNU/Linux.

Previous output (in old broken SD card)

spi mode: 0
bits per word: 8
max speed: 500000 Hz (500 KHz)

Troubleshoot

1. Activated spi with sudo raspi-config and also with sudo nano /boot/config.txt and got

   dtparam=spi=on
   

2. Got output for lsmod as

   Module            Size            Used by
   ...               ...             ...
   spidev            7373            0
   i2c_bcm2835       7167            0
   bcm2835_gpiomem   3940            0
   spi_bcm2835       7596            0
   i2c_dev           6913            0
   ...               ...             ...
   

3. ls -l /dev/spi* shows

   crw-rw---- 1 root spi 153, 0 Jul 9 17:19 /dev/spidev0.0 
   crw-rw---- 1 root spi 153, 1 Jul 9 17:19 /dev/spidev0.1
   

Question

1. So, How can I check my spi driver for linux whether it is working or not while my Broadcom BCM2837 and activated modules for bcm2835?
