[dependabot]

Updates the requirements on minitest to permit the latest version.
Updates minitest to 6.0.2

Changelog

Sourced from minitest's changelog.

=== 6.0.2 / 2026-02-23

• 7 bug fixes:

  • Added missing drb dependency from minitest-server. (y-yagi)
  • Cleaned up bisect's sub-commands to load files directly, not ruby+require.
  • Fixed bisect to use same cmd ($0) to run tests as original invocation.
  • load server_plugin if server is loaded. (y-yagi)
  • Manipulate local args instead of ARGV in Sprint.run.
  • Only show --bisect in usage if using minitest.
  • Remove -Itest:lib from bisect's rb_flags since bin/minitest adds them.

=== 6.0.1 / 2025-12-26

• 1 minor enhancement:

  • Added new rake task test:fu to Minitest::TestTask, to only run tests with FU (focused units?) in their name. This should mostly obviate the need for the minitest-focus plugin.

• 5 bug fixes:

  • Fixed --help and --version exiting 1. (grosser)
  • Fixed method signature of Minitest::Benchmark.run. (flavorjones)
  • Flush stdout/stderr before exit./bin/minitest -Ilib ./bug1046.rb:1 < /dev/null (grosser)
  • Improved usage banner output by reordering and reformatting.
  • Normalize paths while processing file.rb:line args.

=== 6.0.0 / 2025-12-17

This is a major release. Read this.

Please give feedback here: minitest/minitest#1040

Oh god... here we go... (again)

• 8 deaths in the family(!!):

  • Deleted MiniTest and MiniTest::Unit::TestCase compatibility namespaces.
  • Deleted all use of Marshal for serialization.
  • Deleted maglev? and rubinius? guard methods. LOL.
  • Deleted all minitest/spec expectations from Object. Use _/value/expect.
  • Dropped minitest/mock.rb. This has been extracted to the minitest-mock gem.
  • assert_equal(nil, value) no longer allowed. Use assert_nil to be explicit.
  • Removed assert_send. Use assert_predicate or assert_operator.
  • Removed Minitest::Test#class_name.

• 7 major (oft incompatible) changes:

  • Big: Major refactored MT6's run path!
