Tout
Tout is a small helper for altering the visibility of methods while testing them. This allows classes to be structured with normal public/private methods while still maintaining full test coverage.
Tout allows a private method to be made public only for the duration of the test group, it sets the method back to private at the end of the example group to avoid any possible side effects.
Usage
Tout allows the easy and safe testing of private methods via the publicize
helper like so:
publicize(class, :method_name)
Here it is in use in a small test suite:
class NormalClass
def public_foo
"public"
end
private
def private_foo
"private"
end
end
describe NormalClass do
describe "#private_foo"
publicize(described_class, :private_foo)
it "returns 'private'" do
expect(described_class.private_foo).to eq("private")
end
end
end
