Rule is DEPRECATED
use expect-matcher
and expect-single-argument
instead.
Ensure expect()
is called with a single argument and there is an actual expectation made.
This rule triggers a warning if expect()
is called with more than one argument or without arguments.
It would also issue a warning if there is nothing called on expect()
, e.g.:
expect();
expect("something");
or when a matcher function was not called, e.g.:
expect(true).toBeDefined
This rule is enabled by default.
The following patterns are considered warnings:
expect();
expect().toEqual("something");
expect("something", "else");
expect("something");
expect(true).toBeDefined;
The following patterns are not warnings:
expect("something").toEqual("something");
expect([1, 2, 3]).toEqual([1, 2, 3]);
expect(true).toBeDefined();
