Assertion for http header

Question

Im doing some Unit testing to node application and I check for http response. currnlty I want to test also the http.header response for key and value which I send,what am I doing wrong ?

res.header.should.have.property['prop1'];

1. Assume that I've prop1, how should I do that ?
2. in addition how to assert to the value of prop1 ?

Answer 1

You should be calling property, not indexing into it:

res.header.should.have.property('prop1');

You can simultaneously check the value by passing it as a second argument:

res.header.should.have.property('prop1', 'propValue');

Answer 2

You should try something like

res.header.prop1.should.equal('propValue');

This answer both...
