For identifying a particular Test case is python a new field will be introduced in managed scripts. This new field will be used to mark particular test case as Python or not. The below are the stepwise information on how a particular test case will executed

1. The below alter scripts needs to be executed in Automatics Orchestration DB

   1. Code Block
      language sql title Alter scripts linenumbers true
      alter table script_details add TEST_SCRIPT_TYPE varchar(25) default 'JAVA'; alter table script_details add IS_PYTEST_TC boolean default false; insert into available_job_params (PARAMETER_NAME,UPDATED_BY) values ('Test_Script_Type','admin'); insert into available_job_params (PARAMETER_NAME,UPDATED_BY) values ('is_pytest_testCase','admin');

2. At first Python test case should be added in automatics, for that when adding a new test case the new test case identification field should be selected as Python and saved in Automatics., the the second field  to identify the particular test case is using Pytest framework or not .
   1. Image Added
3. Once a Test case is triggered, Automatics will first check whether the test case is Python or not, by using the value in the new identification field.
4. Once Jenkins job for Python script execution is triggered from automatics, it will pull the latest Python code from the configured repo along with the latest automatics core RDK B or V tests and it will invoke the corresponding Python script using JEP Java Process builder based on the Automation ID of the test case.

Enable Python scripts to use Automatics Core, Test Utils & Props

...

1. The below python script will invoke AutomaticsTapApi java class in Automatics Core to get the current execution mode if available AutomaticsTapAPI.py
