.put() does not work as expected

This comment is pretty old... but came across the same issue. Explicitly setting Content-Type in header resolved it. For example:

suite.use('localhost', 3000)
    .path('/users')
    .setHeader('Content-Type', 'application/x-www-form-urlencoded')
    .put({ firstName: 'Testibus', lastName: 'Testman' })
        .expect(200)
