Häufige Annahme

Calling assert_same with nil compares identity using equal? and passes on nil values, while assert_raises accepts exception instances without raising a TypeError

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• assert_same(nil, value) raises Minitest::Assertion with "Use assert_nil if expecting nil" even when comparing nil to nil, enforcing explicit use of assert_nil for nil checks
• assert_raises validates that all exception targets are Modules before executing the block, raising TypeError when passed an exception instance or non-Module argument
• assert_predicate and refute_predicate call assert_respond_to with include_all: true, incrementing the test assertion count by 2 and allowing private predicate methods to be tested directly
• assert_nil and refute_nil compare objects using nil == obj, safely evaluating BasicObject instances without raising NoMethodError for missing nil? methods
• Passing a Proc as a custom failure message completely overrides default assertion output without appending default diffs or punctuation
