Hey, I’m using the open zeppelin test helpers, and I’ve repeatedly noticed a very strange behavior, which is that my test file seems to magically add a require statement at the top of my file if I type some special things. Specifically, I’ve seen that I typed latestBlock and then ran my tests, and boom! The top of my file then contained const { latestBlock } = require('@openzeppelin/test-helpers/src/time'); . I 100% absolutely no questions asked did not add this import. I’ve also seen this happen with web3 as well. I can’t replicate every time, but I can confirm this has happened multiple times. ie. I remove the import, run my tests, and the import statement comes back.
Anyone run into this or know what’s going on? It almost seems like some pre-processor (perhaps from Buidler or Truffle) is running that looks for keywords from my test files and automatically adds imports if it can. Which if so, is insane, and I at least want to know it’s happening, and probably turn it off somehow.
Environment
I’m using OpenZeppelin test helpers 0.5.6, Open Zeppelin contracts 3.1.0, Buidler 1.4.3. Also buidler-truffle5 of 1.3.4, and truffle-contract 4.2.1. When I run my tests, I use npx buidler test --show-stack-traces , through npm test. This is all just on my local Macbook Pro, on Catalina 10.15.6
