Testing

Unit test are critical to the OpenZeppelin framework. They help ensure code quality and mitigate against security vulnerabilities. The directory structure within the /test directory corresponds to the /contracts directory. OpenZeppelin uses Truffle testing framework(based on the Mocha JavaScript testing framework) and the Chai assertion library. To learn more about how tests are structured, please reference OpenZeppelin’s Testing Guide.
