Projects like https://netflix.github.io/pollyjs/ let you replay when the recording exists (ideal), or record if it's missing.

When working on tests/features, this behavior is desirable to having to switch TEST_MODE & continually re-running tests/code.

Let's say there is a function F(x) such that x is an object, and freturns a Promise. If inside of f, x is mutated, such as via x.a = 'blah', then the arguments that get serialized to the mock file will include a: "blah". Instead, the arguments to f should be snapshotted at the time that the function is called, and what is serialized to the mock file should not reflect later mutations.

Would be nice if wrapAsyncMethod supported Promises. Could submit a PR if you're open to it

Great product. Wanted to try a simple test in capture and then replay mode for a mocha test. I am trying to make it work with a browser test, which opens a site in a browser, captures the traffic and then replays the traffic when machine is not connected to Internet at all. Is that something doable?

Which is the approach to use easy-fix in a Continuos Integration env? It's not clear for me at this moment. Which mode should I use to run the integration tests in a CI? Which should be the proper flow? I'm a bit confused

This would allow the filename to be dynamic based on the args provided to the call.
