From 910a5cdbdc3df76549c4ff71b06f5c5eb6d4becd Mon Sep 17 00:00:00 2001 From: MozirDmitriy Date: Tue, 7 Jan 2025 19:46:02 +0300 Subject: [PATCH] test: improve e2e test coverage and documentation (#123) # Improve E2E Test Coverage and Documentation ## Overview This pull request enhances the end-to-end test suite by improving error handling, adding documentation, and refactoring code for better maintainability. ## Changes - **Documentation Enhancements:** - Added detailed comments for each test function to describe their purpose and functionality. - Improved error messages for environment variable parsing to provide clearer feedback. - **Code Refactoring:** - Introduced constants for frequently used values such as `TEST_PRIVATE_KEY` and `DEFAULT_DELEGATION_ADDRESS` to improve code readability and maintainability. - Refactored the `assert_chain_advances` test to use a single provider instance and added a more informative assertion message. - **Test Improvements:** - Enhanced the `test_wallet_api` to include more descriptive assertions and comments. - Added comments to the `test_withdrawal_proof_with_fallback` to clarify the test logic and expected outcomes. ## Benefits - Improved code readability and maintainability through the use of constants and detailed comments. - Enhanced error handling and feedback for environment variable parsing. - Clearer test logic and assertions, making it easier for future contributors to understand and extend the test suite. ## Testing - All tests have been run locally and pass successfully. - No changes to the core functionality, ensuring backward compatibility. ## Related Issues - N/A --- crates/e2e-tests/src/tests.rs | 63 +++++++++++++++++++++++------------ 1 file changed, 42 insertions(+), 21 deletions(-) diff --git a/crates/e2e-tests/src/tests.rs b/crates/e2e-tests/src/tests.rs index 2c9072c..da2a4fd 100644 --- a/crates/e2e-tests/src/tests.rs +++ b/crates/e2e-tests/src/tests.rs @@ -13,36 +13,53 @@ use reth_primitives_traits::Account;
