to check file has the same value or not i e comparing file with stat module

Question

I can see a file i.e., test.txt on remote1 and remote2 which has version with date and these file contains aren't fixed.

$ cat test.txt
Release_P1.11_2017-08-02-094316
02/08/2017

I wanted to set the condition to check if file contains are same then continue to perform further tasks and if they are not the same then stop the tasks

 ---
   - name: latest file check
     stat:
        path: /tmp/test.txt
        get_checksum: yes
     register: test_file_check

   - debug:
        var: test_file_check.stat.checksum
Checksum value are equal if file contains will be same, otherwise it's not the same.
I am unable to figure it out. Can anyone help me with this?
Thanks

Try the following script:

Do the second time check and when condition be like:

- hosts: remote_1
  tasks:
    - name: first file check
      stat:
        path: /tmp/test.txt
        get_checksum: yes
      register: test_file_check_1

...........................................
- hosts: remote_2
  tasks: 
    - name: next check
      stat:
        path: /tmp/test.txt
        get_checksum: yes
      register: test_file_check_2
...........................................

- name: Block run only if file has no changes
  command: /bin/true
  when: test_file_check_1.stat.checksum == test_file_check_2.stat.checksum
