Example 31 with TestDatabaseManagementServiceBuilder

use of org.neo4j.test.TestDatabaseManagementServiceBuilder in project neo4j by neo4j.

the class UniqueConstraintCompatibility method setUp.

/*
     * There are a quite a number of permutations to consider, when it comes to unique
     * constraints.
     *
     * We have two supported providers:
     *  - InMemoryIndexProvider
     *  - LuceneIndexProvider
     *
     * An index can be in a number of states, two of which are interesting:
     *  - ONLINE: the index is in active duty
     *  - POPULATING: the index is in the process of being created and filled with data
     *
     * Further more, indexes that are POPULATING have two ways of ingesting data:
     *  - Through add()'ing existing data
     *  - Through NodePropertyUpdates sent to a "populating updater"
     *
     * Then, when we add data to an index, two outcomes are possible, depending on the
     * data:
     *  - The index does not contain an equivalent value, and the entity id is added to
     *    the index.
     *  - The index already contains an equivalent value, and the addition is rejected.
     *
     * And when it comes to observing these outcomes, there are a whole bunch of
     * interesting transaction states that are worth exploring:
     *  - Adding a label to a node
     *  - Removing a label from a node
     *  - Combinations of adding and removing a label, ultimately adding it
     *  - Combinations of adding and removing a label, ultimately removing it
     *  - Adding a property
     *  - Removing a property
     *  - Changing an existing property
     *  - Combinations of adding and removing a property, ultimately adding it
     *  - Combinations of adding and removing a property, ultimately removing it
     *  - Likewise combinations of adding, removing and changing a property
     *
     * To make matters worse, we index a number of different types, some of which may or
     * may not collide in the index because of coercion. We need to make sure that the
     * indexes deal with these values correctly. And we also have the ways in which these
     * operations can be performed in any number of transactions, for instance, if all
     * the conflicting nodes were added in the same transaction or not.
     *
     * All in all, we have many cases to test for!
     *
     * Still, it is possible to boil things down a little bit, because there are fewer
     * outcomes than there are scenarios that lead to those outcomes. With a bit of
     * luck, we can abstract over the scenarios that lead to those outcomes, and then
     * only write a test per outcome. These are the outcomes I see:
     *  - Populating an index succeeds
     *  - Populating an index fails because of the existing data
     *  - Populating an index fails because of updates to data
     *  - Adding to an online index succeeds
     *  - Adding to an online index fails because of existing data
     *  - Adding to an online index fails because of data in the same transaction
     *
     * There's a lot of work to be done here.
