This repository is used to store test code, test the features of different versions of the solidity language features on XDC.

Test features

Testing features of v0.8.24

• Testing block.blobbasefee: global function, retrieve the blob base fee of the current block.

• Testing blobhash(uint): global function, retrieving versioned hashes of blobs, akin to the homonymous Yul builtin.
• Testing blobbasefee(): Yul builtin, retrieve the blob base fee of the current block.
• Testing blobhash(): Yul builtin, retrieve the versioned hashes of blobs associated with the transaction.
• Testing mcopy(): Yul builtin, cheaply copy data between memory areas.
• Testing tload()and tstore(): Yul builtin, load and store data from transient storage.

Testing features of v0.8.25

• Code Generator: Use MCOPY instead of MLOAD/MSTORE loop when copying byte arrays.
• EVM: Set default EVM version to cancun.
• Yul Analyzer: Emit transient storage warning only for the first occurrence of tstore.

Testing features of v0.8.26

• Introduce a new overload require(bool, Error) that allows usage of require functions with custom errors. This feature is available in the via-ir pipeline only.

Testing features of v0.8.27

• Make require(bool, Error) available when using the legacy pipeline.
• Yul: Parsing rules for source location comments have been relaxed: Whitespace between the location components as well as single-quoted code snippets are now allowed.

Testing features of v0.8.28

• if support transient storage state variables of value types.

Test guide

Before starting, please ensure that your development environment meets the following requirements:

• Node.js: version 12.x or higher.
• npm: used to manage project dependencies.

How to test

1. Clone the repository

   git clone [email protected]:JukLee0ira/solidityTesting.git
   cd solidityTesting

2. Install dependencies

   Use npm to install the project dependencies:

   npm install

3. Configure environment variables

   Create a .env file in the project root directory and configure it according to the following example:

   PRIVATE_KEY=your private key
   RPC_URL=your RPC URL
   

   Note: Please ensure that your private key and RPC URL are valid, and do not publicly expose your private key.

Use Hardhat to test

1. Compile contracts

   Run the following command in the project root directory to compile the contracts:

   npx hardhat compile

2. Run tests

   Choose your test network and use the following command to run the tests:

   npx hardhat test --network <your testnet>

   now you should see the test results of each feature
