This is using two different files to make sure that changing the value actually works.

So you probably need to create two images (can both be druplicon.png as source I think).

This looks good. We can open a follow-up issue to split the huge class into multiple classes with more separate test methods so that it's more like a unit and not a web test. We can also add a base test class then but it's not that useful to add a base class if we currently only have a single class that would use it.

The TypedDataTest::createTypedData() $context parameter defaults to an array, but it is passed on as the $name parameter to TypedDataManager::create(), which should be a string. @fago confirmed this on IRC:

fago: Xano, it should be updated to match the typed data manager's create() parametrs

Now with parameter name change.

Clean-up looks correct and seems to be blocking other tests. Back to RTBC.

Great, faster tests++ :)

Committed and pushed to 8.x. Thanks!
