What is the test coverage?

[Yuxin Liu]

I ran the npm run test, and got a result of "57 tests passed". Is there any information about the radio on test coverage?

You can run AVA with the --verbose flag to list every tests when they are passed.

npx ava --verbose

Or else you can look at the test directory to have deep insights on the tests.
I hope that answers your question.

Thanks for the reply. I can list all tests that are passed, and there are 57 tests in total. But sadly, I still don't know the code coverage information of the test. (Some npm packages show their code coverage such as 94% or 100%.)

You can run ava with c8 to calculate code coverage: https://github.com/avajs/ava/blob/main/docs/recipes/code-coverage.md

Though bigger question is: What causes your interest?

It's easy to get a 100% test coverage, it's much harder to write tests that actually verifies the intended functionality.

Highlighting code coverage isn't very useful and not a very good metric to eg. evaluate modules by.

Cool! c8 works well. Thanks for the advice 🌹

I'm doing research about Software Analysis; I need to collect popular projects with high code coverage tests.😊

Such a cool discussion :)
