What are the meaning of these values?
Are invalid values rejected? I don't see any code/tests for that.

Explaining the values would be out of scope of the Python documentation. I think invalid values should be accepted, after all its browser's job to discard invalid values. Suppose, in future they proposed or added another value for SameSite then we need to make space for that too. By the way i'm not sure about this, let the member decide.

Tim is correct that we need to add a test for invalid values. However, we need to decide on what we should do with invalid values first. I don't have time to do a research at the moment, but just a note that Firefox doesn't implement SameSite support yet: https://bugzilla.mozilla.org/show_bug.cgi?id=795346

You're right. However, chrome implemented SamSite. Right now only Chrome implemented this. https://bugs.chromium.org/p/chromium/issues/detail?id=459154
I checked the test cases they wrote for the same, i didn't find test cases for invalid values.
