Is there a function similar to bodyContains but for headers?

[Cenric]

I am trying to expect a value in the header to contain certain text, something like

.expect('header', 'key', startsWith('value'))

but nothing seems to work. I see that there is a built in bodyContains function, was wondering how I could do this for running an expect on a header key/value as well?

value parameter is regular expression.

.expect('header', 'key', /^value/))

I think this test will be helpful.

Thank you so much, this helped a lot!
