Require a message for toThrow() (require-to-throw-message)
toThrow() (and its alias toThrowError()) is used to check if an error is
thrown by a function call, such as in expect(() => a()).toThrow(). However, if
no message is defined, then the test will pass for any thrown error. Requiring a
message ensures that the intended error is thrown.
Rule details
This rule triggers a warning if toThrow() or toThrowError() is used without
an error message.
Default configuration
The following patterns are considered warnings:
test('all the things', async () => {
expect(() => a()).toThrow();
expect(() => a()).toThrowError();
await expect(a()).rejects.toThrow();
await expect(a()).rejects.toThrowError();
});
The following patterns are not considered warnings:
test('all the things', async () => {
expect(() => a()).toThrow('a');
expect(() => a()).toThrowError('a');
await expect(a()).rejects.toThrow('a');
await expect(a()).rejects.toThrowError('a');
});
