bun:test/no-alias-methods

Some matchers have two names. For example, toBeCalled is the same matcher as toHaveBeenCalled. If a project uses both, a search for one name misses the tests that use the other.

--fix renames the matcher.

Configure#

Off by default. To turn it on:

bunfig.toml

[lint.rules]
"bun:test/no-alias-methods" = "error" # or "warn"
