A key aspect of your blockchain development is the creation and testing of smart contracts. Once you deploy smart contracts, it’s impossible to modify them. So, Solidity testing is a critical step in the creation process. However, the process of smart contract testing is challenging and requires the help of an experienced Blockchain development company. Such a firm knows the best strategies and tools to use in auditing and testing solidity contracts. Keep reading to know the best tools to use when testing solidity smart contracts.
Why testing smart contracts is vital in Blockchain development
Here are the primary benefits of smart contract penetration testing:
- Tests authentic behavior: pentesting smart contracts helps to check whether the agreements function as intended. If the contracts don’t perform as planned, you can identify and fix the issues before deploying the agreements.
- Check any side effects of added code: some added code might introduce errors in the smart contract at the development stage. So, Solidity testing allows you to check whether you’ve harmed any past functionalities.
- Simplification of refactoring: an excellent testing suite helps you to know the specific areas to focus. This allows you to avoid wasting time by overhauling the whole solution.
- Handling of high-value settlements: smart contracts hold assets of high value. So, simple mistakes can cause significant asset loss. Thus, smart contract testing is the only way to discover vulnerabilities in your creation.
- Digital contracts are immutable: once you deploy smart contracts, it’s impossible to alter them. This means that you lack a chance to fix flaws if you discover them later after deploying the agreements. So, testing solidity contracts is the best way to identify and fix bugs before launching your product.
How do you test digital contracts?
Usually, you carry out Solidity testing through the application of Solidity and JavaScript. Solidity is the programming tool used to build digital agreements that operate on the Ethereum network. During Blockchain development, you can use solidity to evaluate the internal qualities of Solidity virtual agreements. On the other hand, JavaScript is helpful when checking your solution’s external conduct.
Which tools do you use for testing smart contracts?
Here are the primary tools to apply when testing smart contracts:
Truffle
Truffle is a test application suitable for networks that use EVM. The model allows you to craft easy-to-handle tests via JavaScript and Solidity.
Truffle offers a clean setting when running your testing files. With the snapshotting feature, Truffle ensures that your files remain separate all the time.
Regarding speed, Truffle is faster than many testing tools in the industry. The high speed ensures that you run your tests faster and avoid wasting time.
Ganache
Truffle has a tool known as Ganache, a popular app for testing solidity smart contracts. Ganache has various features, such as a block explorer and Deploy and Run Transactions pane. While the block explorer feature helps track test information, the Deploy & Rub Transaction assists you in introducing your agreement into the mainnet.
Securify
The tool was developed through the collaboration between Ethereum Foundation and ChainSecurity. It can evaluate Ethereum digital agreements to check whether their behavior aligns with your objectives.
Waffle
This is a smart contract penetration testing tool developed by ETHWorks. It’s popular with many smart contract testers because of its simplicity. It enables you to build and test your smart contracts via Mocha and Chai.
Chai is a library that offers features for comparing the results of a specific evaluation with the anticipated value. Its language is simple to understand as it resembles English.
On the other hand, Mocha is a javascript model that works closely with Chai. It is perfect for tasks performed in a particular order and ensures that the evaluation cases operate autonomously.
Oyente
Smart contracts require safety audits before deploying them on the mainnet. Oyente is a famous tool for security testing in Blockchain development. It evaluates various vulnerabilities, such as transaction order dependence, integer overflow, and timestamp.
Mythril
It’s a popular testing platform in the blockchain development field. It uses the latest evaluation strategies, such as symbolic execution and taint assessment. Besides Ethereum, the suite helps many other networks. Testers only need to provide their smart contract address, and the tool starts evaluating it immediately. Some flaws the platform checks includes random number, timestamp, and deprecated elements.
Final words
Pentesting smart contracts is a critical phase before deploying them on the mainnet. Because the contracts hold high-value assets, evaluating whether they contain any development mistakes is vital. Doing so helps you clear the bugs, vulnerabilities, and flaws. The tools explored here can help you perform your tests.
