TestFrameworkDetectionTest test case might fail running independently

[voxik]

Trying to run shoulda-context 2.0.0 test suite with Bundler 4.0, I observe the following test error:

  1) Failure:
TestFrameworkDetectionTest#test_: TestFrameworkDetection should detect Minitest 5.x when it is loaded standalone.  [test/shoulda/test_framework_detection_test.rb:31]:
Expected: ["Minitest::Test"]
  Actual: ["Resolving dependencies..."]

After analysis, there seems to be some issue with Bundler 4.0 always printing the "Resolving dependencies..." message.

Nevertheless, the point is that the test case could be more robust, because I can reproduce the issue also with Bundler 2.6.9 the following way:

$ bundle -v
Bundler version 2.6.9

$ rm gemfiles/test.gemfile.lock 

$ TEST_FRAMEWORK=minitest BUNDLE_GEMFILE=gemfiles/test.gemfile ruby -Ilib:test -rsingleton -e 'require "shoulda/test_framework_detection_test.rb"'
Run options: --seed 64350
