Hi,

How I fill config.native before run onReady in unit test? I need test synchronization config.native (from admin web page config data) and iobroker object database.

By default the tests take what is defined in io-package.json

It`s not appropriate, because I need test following cases:

• Add new row in my web admin page. It is should be correct synchronization with iobroker database
• Delete row in my web admin page. It is should be correct synchronization with iobroker database
• Change exists row in my web admin page. It is should be correct synchronization with iobroker database
• Receive from low-level device some command by my adapter. It is should be correct change state in iobroker database
• Call from user code SetState function. It is should be correct state change in my adapter and send correct command to low-level device

I think that adapter should be create in each test suite (for example in describe->beforeEach may be) or is there another way to test my adapter

So you want to dynamically change the adapter config before each test?

Yes. I need configure my adapter or emit command from low-level device (via mock) before each test.

Also needed in some cases where default values can not be used for testing ...

There is now the property overwriteAdapterConfig on the test options object.
