Feature Request: Report all failures

[greena13]

HealthBit version: 0.1.8

Currently only the first failed check is returned. It would be nice to have an option to continue beyond the first failed check and report all failures.

Same here I think its crucial! Not a lot of work but would be a breaking change for custom formatter as they now would receive an array of errors to format instead of one.

This monkey patch does it for me though:

module HealthBit
  def check(env)
    results = checks.map do |check|
      check.call(env)
    end

    results.compact
  end

  def rack(this = self)
    @rack ||= Rack::Builder.new do
      run ->(env) do
        errors = this.check(env)
        if errors.any?
          [
            this.formatter.code_failure(errors, env, this),
            this.formatter.headers_failure(errors, env, this),
            [this.formatter.format_failure(errors, env, this)]
          ]
        else
          [
            this.formatter.code_success(env, this),
            this.formatter.headers_success(env, this),
            [this.formatter.format_success(errors, env, this)]
          ]
        end
      end
    end
  end

  class Formatter
    # @param errors [HealthBit::CheckError]
    # @param env Hash
    # @param health_bit HealthBit
    def format_failure(errors, env, health_bit)
      format = health_bit.show_backtrace ? CheckError::FORMAT_FULL : CheckError::FORMAT_SHORT
      errors.map { |error| error.to_s(format) }.join("\n")
    end
  end
end

Here the code change but we need to either ship a breaking change or work around it somehow AxelTheGerman@2741a69
