Environment:

  • vert v1.0.0
  • chai v5.1.1
  • mocha v10.4.0
• Antelope cdt v4.0.1

Description

I have added unit tests for my smart contract using vert, mocha and chai. When running them, they always fail with the error Not implemented _ashlti3. Here is call stack:

To export memory i use wabt, which is called with script from official documentation:

wasm2wat FILENAME.wasm | sed -e 's|(memory |(memory (export "memory") |' > TMP_FILE.wat
wat2wasm -o FILENAME.wasm TMP_FILE.wat
rm TMP_FILE.wat

Unfortunately, the smart contract is too long to include here. So if you have any specific questions about it, please let me know. I will do my best to answer them.
