| # php-document-store | ||
|
|
||
| Event Engine PHP Document Store Contract | ||
|
|
||
| ## Testing | ||
|
|
||
| This package includes an in-memory implementation of the `DocumentStore` interface which is useful for tests. | ||
| To be able to test the in-memory implementation in isolation we have to copy some classes from `event-engine/persistence` into the test namespace of this repo. | ||
| The implementation depends on classes from that other package, but we cannot pull it with composer due to circular dependencies. | ||
| We'll solve the issue in the future by moving the in-memory implementation to `event-engine/persistence`, but for now backwards compatibility is more important. |
