Description

Describe the bug

I have written a simple integration test case to my stack in Python, but I am not able to run it. I used integ-runner and tried with cdk deploy --app "python integration_test.py" but it seems none of them are working. Is this feature available only with ts library?

Many thanks

Expected Behavior

Able to run my tests.

Current Behavior

yarn's integ-runner cli uses *ts files to run tests, so with my python code it will not compile

with cdk deploy --app "python integ_tests.py" the stack deployed, but nothing happened

Reproduction Steps

app = App()

stack = Stack(app, "stack",env=default_env)
integ = IntegTest(app, "Integ", test_cases=[stack])

invoke = integ.assertions.invoke_function(
    function_name=stack.writer_lambda.function_name
)
invoke.expect(ExpectedResult.object_like({
    "Payload": "200"
}))

Research direction
Investigate the integ runner CLI code in the aws cdk repository to understand how it currently discovers and executes TypeScript test files. Explore how to extend the runner to support Python or other language test files, possibly by adding a configuration option or language plugin. Review any existing issues or discussions about multi language support.
