使用sinon，nyc和ava测试js / esm项目-尽管有控制台日志，在控制台上进行w / spy测试仍失败

Question

I have an esm project I'm trying to test with ava , nyc and sinon . I have had some success using sinon to spy on console.log and report whether or not it is being called, but on another set of files, where I feel I'm doing the same things, I can't get it to work. I don't know if it's sinon or ava or what is the problem. I made a test repo here . When you run npm run test it will fail and say console.log was not called, but you can see at the top of the output a statement was logged. What am I doing wrong?

Thank you!

Answer 1

main() is asynchronous and you only call console.log() after awaiting. At that point you've already torn down the spy. Use await main() and make the test implementation asynchronous as well.
