[Bug]: $referenceRepository->getReferences() is broken

[alexislefebvre]

Preconditions

Current version of the bundle.

getReferences() gives wrong results: it contains 1 fixture when it should contain 2.

Steps to reproduce

See

• 244

Expected result

References should contain as many entries than data that was loaded.

Actual result

Only one fixture is returned.

Possible solutions

• fix MysqlDatabaseBackup
• measure if backups are useful to speed up tests, and if the difference is not huge, deprecate all the backup classes and publish a 3.x release without the cache

Caches have been removed from 3.x:
