Or condition is not working with set_facts in my playbook - ansible

Question

I created one playbook to run the tasks based on the test case so I have created like below
Here when I pass the ansible-playbook playbook.yml -e stage=1, it's skipping all the tasks, and when I debug the test_case* values I could see both are in a false state, So can some help me to work this code.
---
- name: test
hosts: localhost
tasks:
- name: setting the level
set_fact:
test_case_1: "{{ stage == 1 }}"
test_case_2: "{{ stage == 1 or stage == 2 }}"
- name: "running ls command"
shell: "ls -l"
register: testing
when:
- test_case_1 == true
- debug:
msg: "{{ testing.stdout_lines }}"
when:
- test_case_1 == true
- name: "kickoff"
shell: "df -Th"
register: kick
when:
- test_case_2 == true
- name: "printing kickoff"
debug:
msg: "{{ kick.stdout_lines }}"
when:
- test_case_2 == true
Below is the error results which I am getting
[root#server ~]# ansible-playbook playbook.yml -e stage=1
PLAY [test] ***********************************************************************************************************
TASK [Gathering Facts] ************************************************************************************************
ok: [localhost]
TASK [setting the level] **********************************************************************************************
ok: [localhost]
TASK [running ls command] *********************************************************************************************
skipping: [localhost]
TASK [debug] **********************************************************************************************************
skipping: [localhost]
TASK [kickoff] ********************************************************************************************************

skipping: [localhost]
PLAY RECAP ************************************************************************************************************
localhost : ok=2 changed=0 unreachable=0 failed=0 skipped=4 rescued=0 ignored=0
[root#server ~]#
expected results should be, it should execute all the tasks from the play.

Your problem is that you are performing an integer comparison (stage == 1), but when you provide a value on the command line via -e stage=1, you are setting a string value.
You probably want to case the value of stage to an integer using the int filter.

- name: test
hosts: localhost
tasks:
- name: setting the level
set_fact:
test_case_1: "{{ stage|int == 1 }}"
test_case_2: "{{ stage|int == 1 or stage|int == 2 }}"
With this change, things seem to work as expected.
Unrelated to your question, but you could rewrite the second test like this:
{{ stage|int in [1, 2] }}
That simplifies things a bit.
