hevm Description
The hevm project serves as a tailored implementation of the Ethereum Virtual Machine (EVM) designed for tasks like symbolic execution, unit testing, and debugging of smart contracts. Created by DappHub, it seamlessly integrates with the suite of tools offered by the same developer. The hevm command line interface enables users to symbolically execute smart contracts, conduct unit tests, debug contracts interactively while displaying the Solidity source code, or execute any arbitrary EVM code. It allows computations to be carried out using a local state established within a testing framework or retrieved from live networks through RPC calls. Users can initiate symbolic execution with specified parameters to detect assertion violations and can also customize certain function signature arguments while keeping others abstract. Notably, hevm adopts an eager approach to symbolic execution, meaning that it initially strives to investigate all branches of the program. This comprehensive method enhances the reliability and robustness of smart contract development and testing.

Testsigma
Testsigma is a low-code end-to-end test automation platform for Agile teams. It lets SDETs, manual testers, SMEs, and QAs collaboratively plan, develop, execute, analyze, debug, and report on their automated testing for websites, native Android and iOS apps, and APIs. It is available as a fully managed, cloud-based solution as well as a self-hosted instance that is open source (Testsigma Community Edition).
The platform is built with Java, but the automated tests are code-agnostic. Through built-in NLP Grammar, teams can automate user actions in simple English, or generate airtight test scripts with the Test Recorder. With features like built-in visual testing, parametrized or data-driven testing, 2FA testing, and an AI that automatically fixes unstable elements and test steps, identifies and isolates regression-affected scripts, and provides suggestions to help you find and fix test failures, Testsigma can replace tens of different tools in the QA toolchain to enable teams to test easily, continuously, and collaboratively.

Etheno
Etheno serves as a versatile tool for Ethereum testing, acting as a JSON RPC multiplexer, an analytical tool wrapper, and a mechanism for test integration. It simplifies the challenges associated with configuring analysis tools such as Echidna, particularly for extensive multi-contract projects. Smart contract developers are encouraged to leverage Etheno for thorough contract testing, while Ethereum client developers can utilize it for effective differential testing of their implementations. By operating an efficient JSON RPC server, Etheno can route calls to multiple clients seamlessly. It also offers an API that allows for the filtering and alteration of JSON RPC calls, facilitating differential testing by dispatching JSON RPC sequences across various Ethereum clients. Furthermore, Etheno allows users to deploy and engage with multiple networks simultaneously and integrates smoothly with popular testing frameworks like Ganache and Truffle. With the capability to launch a local test network using a single command, Etheno ensures ease of setup. Users can also take advantage of a prebuilt Docker container for a quick installation and trial of Etheno. Given its versatility, Etheno offers a wide array of command-line arguments, catering to diverse testing needs and preferences. This flexibility makes it an invaluable resource for anyone involved in Ethereum development.

Mayhem
Mayhem is an innovative fuzz testing platform that integrates guided fuzzing with symbolic execution, leveraging a patented technology developed at CMU. This sophisticated solution significantly minimizes the need for manual testing by autonomously detecting and validating defects in software. By facilitating the delivery of safe, secure, and reliable software, it reduces the time, cost, and effort typically required. One of Mayhem's standout features is its capability to gather intelligence about its targets over time; as its understanding evolves, it enhances its analysis and maximizes overall code coverage. Every vulnerability identified is an exploitable and confirmed risk, enabling teams to prioritize their efforts effectively. Furthermore, Mayhem aids in remediation by providing comprehensive system-level insights, including backtraces, memory logs, and register states, which expedite the diagnosis and resolution of issues. Its ability to generate custom test cases in real-time, based on target feedback, eliminates the need for any manual test case creation. Additionally, Mayhem ensures that all generated test cases are readily accessible, making regression testing not only effortless but also a continuous and integral part of the development process. This seamless integration of automated testing and intelligent feedback sets Mayhem apart in the realm of software quality assurance.
