It seems to me that there perhaps needs to be more clarity here ... I think there is perhaps a difference in between "kernel tests should have fewer depencies" and "mocks missing from Pharo".

Is "Pharo" and "kernel" synonymous?

I imagine that there is a minimal/minimum kernel image that has the kernel and nothing else ... but this kernel image has very little in it and may not even have bare bones development tools ...

I also imagine that there is at least one "Pharo minimal" image (perhaps this is the "kernel" that Guille is referring to?) that is the minimum kernel plus the bare minimum of development tools installed ... no bells and whistles, or anything shiny ... this is the base image that developers would use when they want to build an image aimed at their specific needs ... and of course the image is the starting point for the "developer image" ...

I also imagine that there is at least one "developer image" that is targeted at developers and this image will be billed as the "recommended developers image" and this image should come with the full suite of development tools and supporting projects to make life easy for most developers so that they don't have to customize their development environment from the get-go.

I would think that maintaining the "developer image" would be not that much more complicated than maintaining the 100 or so Contributor builds --- it is built on top of the "Pharo minimal/kernel" image --- all the tests are run, which is the most important thing...

I would say this dependency is needed.

    And again i'll hold my position: whoever wants to load it can do
    it. There is no need to put it there by default.

Do you know how much easier it would be to design and test FileSystem with mocks. Code and tests will be much better and simpler from the beginning.
And I could said it about any package which provide abstractions.

Now no project which is part of Pharo can use mocks for tests. So it is not question of loading it for own project. Pharo contributors can't use mocks.

And there is another story. Imaging Ruby guys join Pharo development (not real story :)). Many years In Ruby people use mocks and "human should" assertions. Most TDD evolution was from Ruby. I imaging their impression about Pharo "the best for TDD".

And generally I would said we have quite bad tests in system. They are slow, they corrupt image. Mocks will help to improve this situation.
