Right now, when an async Vue lifecycle hook such as
mountedthrows/rejects, it seems thatexpect(cleanup).toThrow()is the only way to reliably assert an error. When auto-cleanup is enabled, this would mean thatcleanupis called multiple times for some tests.wrapper.destroy, called bycleanup, rethrows any errors (see @vue/test-utilsthrowIfInstancesThrew). Without try/finally in place, the destroyed wrapper never gets deleted frommountedWrapperswhenwrapper.destroythrows.The assert works, but the test still fails because auto-cleanup throws in
afterEachas it attempts to destroy the wrapper again. It would be tedious to turn off auto-cleanup for the entire test setup, just to call cleanup manually for all remaining tests.Note: I added a test that currently creates some
console.errorlogs, but none of which affect the test outcome negatively. I currently use jest to stub outconsole.errortemporarily. Feel free to remove this if you're fine with some errors being logged.
