## Compatibility Tests
|
|
|
|
These tests attempt to ensure forward and backward compatibility for Dolt versions.
|
|
|
|
For each Dolt release version listed in `test_files/backward_compatible_versions.txt`, a legacy
|
|
repository is created using the corresponding release and populated with data from
|
|
`test_files/setup_repo.sh`. Then, using a Dolt client build at HEAD, a series of BATS tests are run
|
|
against each legacy repository.
|
|
|
|
To test forward compatibility, a repository is created and populated using Dolt built at HEAD. For
|
|
each Dolt release version listed in `test_files/forward_compatible_versions.txt`, the same BATS
|
|
tests are run against the repo created with Dolt at HEAD.
|
|
|
|
Then there is a third set of tests that test bidirectional compatibility, whether older and current
|
|
clients can alternate doing writes on the same DB withut anything breaking. These tests do their own
|
|
initialization and don't rely on the `setup_repo.sh`. Forward compatibility is the limiting factor
|
|
for these tests (fewer versions are forward compatible at any given time), so that's the versions we
|
|
do bidirectional testing against.
