Method: Object#stub
- Defined in:
- lib/minitest/mock.rb
#stub(name, val_or_callable, *block_args, **block_kwargs, &block) ⇒ Object
Add a temporary stubbed method replacing name
for the duration of the block
. If val_or_callable
responds to #call, then it returns the result of calling it, otherwise returns the value as-is. If stubbed method yields a block, block_args
will be passed along. Cleans up the stub at the end of the block
. The method name
must exist before stubbing.
def test_stale_eh
obj_under_test = Something.new
refute obj_under_test.stale?
Time.stub :now, Time.at(0) do
assert obj_under_test.stale?
end
end
– NOTE: keyword args in callables are NOT checked for correctness against the existing method. Too many edge cases to be worth it.
