assert_error_reported(error_class = StandardError, &block)

断言该代码块应导致至少向Rails.error报告一个异常。

如果在yield的代码块中评估的代码报告了匹配的异常,则通过。

assert_error_reported(IOError) do
  Rails.error.report(IOError.new("Oops"))
end

要测试有关报告的异常的更多详细信息,可以使用返回值。

report = assert_error_reported(IOError) do
  # ...
end
assert_equal "Oops", report.error.message
assert_equal "admin", report.context[:section]
assert_equal :warning, report.severity
assert_predicate report, :handled?
# File activesupport/lib/active_support/testing/error_reporter_assertions.rb, line 88
def assert_error_reported(error_class = StandardError, &block)
  reports = ErrorCollector.record do
    _assert_nothing_raised_or_warn("assert_error_reported", &block)
  end

  if reports.empty?
    assert(false, "Expected a #{error_class.name} to be reported, but there were no errors reported.")
  elsif (report = reports.find { |r| error_class === r.error })
    self.assertions += 1
    report
  else
    message = "Expected a #{error_class.name} to be reported, but none of the " \
      "#{reports.size} reported errors matched:  \n" \
      "#{reports.map { |r| r.error.class.name }.join("\n  ")}"
    assert(false, message)
  end
end

assert_no_error_reported(&block)

断言该代码块不应导致向Rails.error报告异常。

如果在yield的代码块中评估的代码没有报告异常,则通过。

assert_no_error_reported do
  perform_service(param: 'no_exception')
end
# File activesupport/lib/active_support/testing/error_reporter_assertions.rb, line 62
def assert_no_error_reported(&block)
  reports = ErrorCollector.record do
    _assert_nothing_raised_or_warn("assert_no_error_reported", &block)
  end
  assert_predicate(reports, :empty?)
end
