to be within

• <string> [not] to be within <string> <string>

Asserts that a string is within a range of strings.

expect('a', 'to be within', 'a', 'd');
expect('b', 'to be within', 'a', 'd');
expect('aabbcc', 'to be within', 'aaa', 'aaz');

In case of a failing expectation you get the following output:

expect('abbbcc', 'to be within', 'aaa', 'aaz');

expected 'abbbcc' to be within 'aaa'..'aaz'

This assertion can be negated using the not flag:

expect('bar', 'not to be within', 'foo', 'baz');
expect('e', 'not to be within', 'a', 'd');
expect('abbbcc', 'not to be within', 'aaa', 'aaz');

In case of a failing expectation you get the following output:

expect('c', 'not to be within', 'a', 'd');

expected 'c' not to be within 'a'..'d'
