Minitest/MultipleAssertions error

[broksonic21]

Expected behavior

Bumping to 0.34.1 shouldn't return errors, but getting throughout our code base

Actual behavior

Offenses:

REDACTED:73:7: W: Minitest/MultipleAssertions: Test case has too many assertions [4/3].
      def test_REDACTED ...
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
REDACTED:85:7: W: Minitest/MultipleAssertions: Test case has too many assertions [18/3].
      def test_REDACTED ...
      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You can pass the --debug option. But it would be best if you can provide a minimal example of the code it's being run against.

# frozen_string_literal: true

class FooTest < ::Test

  def test_it_fails
    _, b = try_update(foo: 3) do
      see(bar: c.bar, baz: "baz")
    end

    assert_eq c.id, b.id
    assert_eq c.foo, b.foo
  end

end

reproes this.

[broksonic21]

nothing to do with asserts, it looks like:

# frozen_string_literal: true

class FooTest < ::Test

  def test_it_fails
    _d, _b = try_update(foo: 3) do
      see(bar: c.bar, baz: "baz")
    end
  end

end

has same error - must be anytime there's a split return value?
