Example 3 with TransformWork

use of com.google.copybara.TransformWork in project copybara by google.

the class SequenceTest method testSequenceTreeStateIsNotCached_allGood.

/**
 * The TreeState passed to a Sequence shouldn't return a cached TreeState after invocation and
 * calling updateTreeState(). Since it could contain many non-cache-safe transforms and the
 * last one could be a safe one. But we shouldn't be able to reuse that cache.
