From c77182c65c0cd798a311bb3da4e32e1f76835e6c Mon Sep 17 00:00:00 2001 From: Alex Wang Date: Fri, 7 Nov 2025 15:17:11 -0800 Subject: [PATCH] test(examples): add wait and handler error test examples - Add testing examples - wait for condition - handler error - Update wait example with Duration change - Update web runner and workflow, only warning on error response so that we can test on funciton exception --- .github/workflows/deploy-examples.yml | 3 +- .gitignore | 1 + README.md | 4 ++- examples/examples-catalog.json | 11 +++++++ examples/src/block_example/block_example.py | 3 +- examples/src/callback/callback.py | 5 ++- .../src/callback/callback_with_timeout.py | 6 ++-- examples/src/handler_error/handler_error.py | 13 ++++++++ examples/src/parallel/parallel.py | 3 +- examples/src/parallel/parallel_with_wait.py | 7 ++-- .../run_in_child_context_large_data.py | 3 +- .../src/step/step_with_exponential_backoff.py | 7 ++-- examples/src/step/steps_with_retry.py | 4 +-- examples/src/wait/multiple_wait.py | 5 +-- examples/src/wait/wait.py | 3 +- examples/src/wait/wait_with_name.py | 3 +- .../wait_for_condition/wait_for_condition.py | 33 +++++++++---------- .../test/handler_error/test_handler_error.py | 32 ++++++++++++++++++ .../test_wait_for_condition.py | 23 ++++--------- .../runner.py | 5 ++- tests/e2e/basic_success_path_test.py | 3 +- tests/runner_test.py | 25 ++++++++++++-- 22 files changed, 142 insertions(+), 60 deletions(-) create mode 100644 examples/src/handler_error/handler_error.py create mode 100644 examples/test/handler_error/test_handler_error.py diff --git a/.github/workflows/deploy-examples.yml b/.github/workflows/deploy-examples.yml index 64e3a63..383d874 100644 --- a/.github/workflows/deploy-examples.yml +++ b/.github/workflows/deploy-examples.yml @@ -158,10 +158,9 @@ jobs: # Check for function errors FUNCTION_ERROR=$(jq -r '.FunctionError // empty' /tmp/invoke_response.json) if [ -n "$FUNCTION_ERROR" ]; then -
