Re-run the test when the test fails.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:

Minitest::Retry.use!( retry_count: 3, # The number of times to retry. The default is 3. verbose: true, # Whether or not to display the message at the time of retry. The default is true. io: $stdout, # Display destination of retry when the message. The default is stdout. exceptions_to_retry:  # List of exceptions that will trigger a retry (when empty, all exceptions will). )
on_failure callback is executed each time a test fails:
Minitest::Retry.on_failure do |klass, test_name, result| # code omitted end
on_consistent_failure callback is executed when a test consistently fails:
Minitest::Retry.on_consistent_failure do |klass, test_name, result| # code omitted end
on_retry callback is executed each time a test is retried:
Minitest::Retry.on_retry do |klass, test_name, retry_count, result| # code omitted end
Minitest::Retry.use! class Minitest::RetryTest < Minitest::Test def test_fail assert false, 'test fail' end end
