I am getting 'assertCookie' failed errors in the Lithium Test Dashboard

Question

I installed a fresh Li3 using this command from the installationguide:

composer create-project --prefer-dist unionofrad/framework project

Afterwards i ran all tests to see if Lithium is working correctly and got the following errors in the Lithium Test Dashboard:

Assertion 'assertCookie' failed in lithium\tests\cases\storage\session\adapter\CookieTest::testWriteDefaultParameters() on line 79: /^Set-Cookie:\s[\w.-]+[write]=value+to+be+written;\sexpires=Mon, 10-Oct-2016 14:17:34 GMT;\spath=// - Cookie not found in headers.

How can i solve these issues to have a clean running Li3?
