Converting tests from October / Winter v1 & v1.1?

[samcoppock]

october V1 and previous winter versions used "../../../tests/bootstrap.php" in the tests.

The file was found in the /tests folder and was referenced in the phpunit.xml file

winter 1.2 no longer has the /tests folder and the phpunit file does not reference "../../../tests/bootstrap.php"
it does however reference "./modules/system/tests/bootstrap/app.php"

Does app.php completely replace bootstrap.php?

Yes. See https://github.com/wintercms/meta/blob/master/l9-upgrade-notes.md#upgrade-unit-testing for more details on converting.
