Spring boot two data sources, unit tests stopped working - spring

Question

I have switched my application to use two data sources, the code runs fine and both are picked up, however my unit tests have started to fail, code is below, help much appreciated.
Caused by: org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Cannot determine embedded database driver class for database type NONE. If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

Answer 1

A database driver was not found on the classpath for the AutoConfiguration to setup while running your test cases.

Answer 2

As #ndrone stated you need to set your database driver. It is unclear if you are attempting to use AutoConfigureTestDatabase. If so you should reference AutoConfigureTestDatabase from the Spring Boot docs.
If this is the case you could specify the Embedded database to use by using the following in your test (configuration):
#AutoConfigureTestDatabase(connection = EmbeddedDatabaseConnection.H2)
Otherwise, you could modify your application.properties in your test folder to specify the connection type such as:
datasource.primary.driver-class-name=org.h2.Driver
datasource.secondary.driver-class-name=org.h2.Driver
