[dependabot]

Bumps rubocop-minitest from 0.39.1 to 0.40.0.

Release notes

Sourced from rubocop-minitest's releases.

RuboCop Minitest v0.40.0

New features

• #355: Add new RuboCop::TestCase as a stable API for testing custom cops with Minitest. The cop under test is derived from the test class name and can be configured with cop_class, cop_config, other_cops, and target_ruby_version. (@​koic)

Changes

• #345: Fix false positives and negatives in Minitest/NonExecutableTestMethod for nested test classes and for test methods defined before the test class. (@​amckinnie)
• #278: (Breaking) Remove the cop argument from inspect_source and investigate in the Minitest test support; the cop under test is now resolved automatically. The test configuration now merges the default configuration for the cop under test and sets AllCops: TargetRubyVersion explicitly. (@​koic)

Pull Request Overview

The dependency update is up to standards according to the automated analysis. However, the library update introduces a breaking change by removing the 'cop' argument from 'inspect_source' and 'investigate' methods in test support. Since the PR diff is limited to the lockfile, it is critical to confirm that any existing tests for custom cops remain compatible with the updated test helpers.

About this PR

• The library update includes a breaking change: the 'cop' argument has been removed from 'inspect_source' and 'investigate' methods in test support. If the codebase uses these methods for testing custom cops, those tests will fail and require updates.

Test suggestions

• Verify that all existing Minitest-based tests pass.
• Ensure no regressions in 'Minitest/NonExecutableTestMethod' logic for nested classes.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify that all existing Minitest-based tests pass.
2. Ensure no regressions in 'Minitest/NonExecutableTestMethod' logic for nested classes.
