import pytest import sys # This script demonstrates how to programmatically run tests from the langchain-tests package. # In practice, you would typically run 'pytest' directly from your terminal. # Ensure langchain-tests and pytest are installed: # pip install langchain-tests pytest # To run all tests within the 'langchain_tests' package: # Use '--pyargs' to treat the target as a Python package, allowing pytest to discover tests. test_target = "langchain_tests" print(f"Running tests for target: {test_target}") # pytest.main() returns an exit code. sys.exit() uses this code. # -v for verbose output. exit_code = pytest.main(["-v", "--pyargs", test_target]) if exit_code != 0: print(f"Tests failed with exit code {exit_code}") else: print("All specified tests passed!") # You can also run specific test modules: # exit_code_specific = pytest.main(["-v", "--pyargs", "langchain_tests.unit_tests.test_retrievers"]) # if exit_code_specific != 0: print("Specific retriever tests failed.")
