Convert migrate kernel tests to KernelTestBaseTNG

+1 from me, would love to see this.

Not sure what the CI error is?

Needs a use statement, there a few of these.

Really keen to see this, running from PHPStorm is so convenient. Re-rolled and fixed the absolute namespaces at the same time.

Found the fatal, there was an empty test file. Also changed a few more tests over to KTB. Had some fails with EntityFileTest, not sure if that is specific to my environment or not, see what the bot says.

More empty files.

Some more fixes, I reverted back EntityFileTest because that uses $base_url which doesn't seem to get set correctly in the new KTB.

Down to one fail, not sure how to get the vfs stuff working in MigrateFileTest

Fixed both files tests using vfs, thanks to dawehner for the help getting public:// working.

hmm, that test passed locally for me, could be something to do with the global temp files on the bot.

No, that was just a bad interdiff, I actually moved it. You can tell because its the one that failed in #31 :)

Fixed.

Thanks for the review, pretty excited to get this in, the experience of running these locally is much better although its a shame the bot doesn't give better results.

Feedback done.

I went over the patch looks pretty good to me, every file seemed to have a namespace and a comment update along with the file being moved.

I've removed one assertion from the EntityFileTest because of a limitation with realpath and vfs which was causing it to fail. We have a similar assertion right below that tests the same thing without vfs anyway.

Forgot the interdiff.

Committed 4478bb1 and pushed to 8.1.x. Thanks!
