Issues with Rspec tests for Travis CI randomly failing from time to time

[koconder]

Referenced here as well: https://github.com/rspec/rspec/issues/29 / Might be an rspec issue - Not that well versed on ruby and rspec to diagnose.

See example Travis CI build: https://travis-ci.org/duracelltomi/gtm4wp/jobs/380080993 - Randomly it all goes through but sometimes fails for no reason, and would work again on some builds. Example repo where the test code is kept is: https://github.com/koconder/wordpress-test-template/tree/master/spec

In the travis ci build you can see

[Thu May 17 08:02:50 2018] 127.0.0.1:41748 Invalid request (Unexpected EOF)
