+Scripts will create the insert sql files for a randomized fake data postgres database. This database is based of the actual db in photowall project.
+```
+npm test
+```
+
+### Writing tests
+
+The tests are held in testcontainers [testcontainers-node](https://github.com/testcontainers/testcontainers-node). One container holding a test postgres database and one container started from the Dockerfile containing the Apollo GraphQL server. These containers have connections with each other.
+
+Each test is build around inserting fake data in the empty db, fetching that data through the GraphQL and with raw Sql queries and then comparing the results.
+
+To write new inserts into the DB generate sql files with js in the src/__test__/db_generator tool. Then load the new sql file in the containerSetup.ts file.
+
+When you have the data you need in the db, write tests in all.test.ts file following the pattern already set.
