module SolidAssert
module Assert
# Expresses a condition and fails if the condition is not satisfied
#
# Usage
# assert false
# assert not_nil_object
# assert !list.empty?, "The list should not be empty at this point"
#
# @param condition The condition to assert
# @param message The optional message when the condition is not satisfied
# @raise {AssertionFailedError} when the condition is not satisfied
def assert(condition, message=nil)
raise SolidAssert::AssertionFailedError.new(message) if !condition
end
# Let you {#assert} a block of code. It comes handy when your assertion requires more than one lines of code
# Usage:
# invariant do
# some_number = 1
# other_number = 2
# some_number == other_number
# end
#
# invariant "Both numbers should be equal" do
# some_number = 1
# other_number = 2
# some_number == other_number
# end
# @param message The optional message when the block doesn't evaluates to a satisfied condition
# @yield The block that will be evaluated for deciding whether the condition is satisfied
def invariant(message=nil)
assert yield, message
end
