Overview

Checks if test cases contain any assertion calls.

Matchers such as must_equal and wont_match are also treated as assertion methods.

Examples:

# bad
class FooTest < Minitest::Test
  def test_the_truth
  end
end

# good
class FooTest < Minitest::Test
  def test_the_truth
    assert true
  end
end

# bad
class FooTest < ActiveSupport::TestCase
  describe 'foo' do
    it 'test equal' do
    end
  end
end

# good
class FooTest < ActiveSupport::TestCase
  describe 'foo' do
    it 'test equal' do
      musts.must_equal expected_musts
    end
  end
end
