Unit Testing

Smart contract unit tests are authored in Javascript.

In this tutorial, we provide two illustrations of unit testing using Hardhat and Truffle.

Each example repository encompasses the following:

  • contracts folder: This holds the smart contract files.
  • test folder: The unit test files are situated under the test folder.
  • README.md file: This contains guidelines for compiling, testing, deploying, and verifying the smart contracts.

In the aforementioned examples, unit tests are incorporated into a single Javascript file. However, you can include as many tests and files as your project necessitates.

In the illustrations, there are three categories of tests:

  • Verifying if a value aligns with what's expected
  • Checking if an event is initiated with the correct arguments
  • Checking if a revert has occured.
