Description
🚀 Feature Proposal
Some new APIs like fetch make use of Error.prototype.cause which jest does not display at all for thrown errors, which makes debugging these errors harder than necessary.
Motivation
It will make errors with cause easier to debug.
Example
test("cause", () => {
try {
throw new Error("cause");
} catch (err) {
throw new Error("wrapped", {cause: err});
}
});Will output only the wrapped error message, which is often unhelpful:
FAIL ./test.js
● cause
wrapped
It'd be better if the cause message would also be shown:
FAIL ./test.js
● cause
wrapped
cause
Pitch
Because Error.prototype.cause is a standard Javascript feature.
