localhost is usually resolves to loopback interface address - 127.0.0.1, however it is possible to bind to different interface. Therefore, the URL might not work.
It's safer to use use :inet.sockname/1 https://www.erlang.org/doc/man/inet.html#sockname-1 to retrieve listening address and then derive an interface address from :inet.getifaddrs/0 https://www.erlang.org/doc/man/inet.html#getifaddrs-0

I see some overlap with a PR I just created. For the ip address I made this PR: #137

Motivation
Sometime can be a little annoying to add the
endpoint_urlto every test file or add it to the test case.As the endpoint url is something that in the majority of times the test needs to interact to be able to use bypass, seems to make sense that it could be grabbed easily. The port seems to be something more internal that not all tests would need to know and use.
Proposed Solution
Add
endpoint_urlfield to bypass struct. Existing code would work normally with existingportattribute.
