It provides a complete EthereumTester API for account management, transaction submission, block mining, and state queries\u2014all running in Python with deterministic, reproducible behavior.\n\nThe library enforces strict input/output formats (hexadecimal strings for hashes and addresses, integers for numeric values) and includes features like auto-mining of transactions, time travel, and manual block mining. It depends on eth-abi, eth-account, eth-keys, eth-utils, rlp, and semantic_version to handle cryptographic operations and data encoding.","worth_installing":"Yes, if you are testing Ethereum applications locally. eth-tester is the standard in-memory simulator for the Ethereum Python ecosystem and has low install friction. However, be aware that maintenance is aging (last release 2025-04-23, no recent commits visible) and the pre-alpha classifier suggests it may not be production-hardened; verify test coverage and reliability for your specific use case before relying on it for critical contract validation."},"id":"eth-tester","links":{"html":"https://skillfed.io/packages/eth-tester","md":"https://skillfed.io/packages/eth-tester.md","pypi":"https://pypi.org/project/eth-tester/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-04-23","license_spdx":null,"license_treatment":"permissive","name":"eth-tester","python_support":"supports_current","summary":"eth-tester: Tools for testing Ethereum applications."},"popularity":{"monthly_downloads":287304,"position":8034,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.13.0b1"}
