The current ->setMethods() has been silently (won't emit any
warning) in PHPUnit 9. And will stop working (current plans)
in PHPUnit 10.
Basically the now deprecated method has been split into:
- onlyMethods(): To point to existing methods in the mocked artifact.
- addMethods(): To point to non existing (yet) methods in the mocked
artifact.
In practice that means that all our current setMethods() calls can be
converted to onlyMethods() (existing) and done. The addMethods() is
mostly useful on development phases, not final testing.
Finally note that <null> isn't accepted anymore as parameter to
double all the methods. Instead empty array [] must be used.

While this is not strictly required, because removal will
happen in PHPUnit 9.0, we are already getting rid of all
uses in core.
From release notes:https://phpunit.de/announcements/phpunit-8.html
assertInternalType() is deprecated and will be removed in
PHPUnit 9. Refactor your test to use assertIsArray(), assertIsBool(),
assertIsFloat(), assertIsInt(), assertIsNumeric(), assertIsObject(),
assertIsResource(), assertIsString(), assertIsScalar(),
assertIsCallable(), or assertIsIterable() instead.
All the setup/teardown/pre/post/conditions template methods
now are required to return void. This was warned with phpunit 7
and now is enforced.
At the same time, fix a few wrong function names,
provider data and param types, return statements...
The tests do not actually do anything, they just make sure that the
method signature is correct on the given PHP version. They are mostly
relevant and useful on 3.3.
