Abort executing playbook if condition not match

[bablu]

 If condition fails it should not go for the next step and exit from there only.

 In following situation,  when: C != test_val    it should exit from here only instead of going to the next step. How can i achieve this.


   - name: Set the output of the this state
     set_fact: A="{{image_avl.stdout}}"         
     tags: avl1

   - name: Define our static value for the desired image number
     set_fact: B={{retain}}                     
     tags: num2

   - name: difference
     set_fact: C = {{A}} - {{B}} 
     tags: del1

   - name: set the desire value  
     set_fact: test_val=1
     tags: fact2 

   - name: condition1
     action: sending email here
     when: C != test_val
     tags: message
 
   - name: condition2
 
   - name: condition3

I don't think this will work, you need to have in inside one {{ }} par.

set_fact: C = {{ A - B }}

You also might need to filter A and/or B through filter int or float
depending on data type.

Just add a fail task:

- fail: msg="Failed because {{ C }} not equal to {{ test_val }}"
when: C != test_val

I tried with fail and it works.

Is this works when we set  any_errors_fatal: true

you can also use "assert" and the execution stops right there and it will not execute any tasks further
