故障運行RSpec的測試爲WebSphere自由檔案Buildpack

Question

我使用了開放源碼軟件Cloud Foundry的自由開源回購簡介Buildpack並運行到以下故障執行bundle exec rspec

681例，3次失敗時 失敗例子：

rspec ./spec/bin/compile_spec.rb:49 # compile script should work with the liberty WEB-INF case 
rspec ./spec/bin/compile_spec.rb:65 # compile script should also work with the zipped up server case 
rspec ./spec/bin/compile_spec.rb:82 # compile script pass environment variable directory 

3個故障都有一個共同的疊層...

1) compile script should work with the liberty WEB-INF case 
Failure/Error: expect(result).to be_success 
expected `#<Process::Status: pid 84398 exit 1>.success?` to return true, got false

罐有人指引我們如何解決這些故障似乎從一個Dir.mktmpdir塊內Open3.popen3調用幹。這些來自主分支的結果https://github.com/cloudfoundry/ibm-websphere-liberty-buildpack/

-Thanks。

Answer 1

我在Travis CI系統中看不到這樣的故障。另外，在本地機器上進行測試並不會導致任何故障。在測試輸出中是否有其他錯誤？在出現故障的情況下，輸出中應該有以stdout:和stderr:開頭的消息。

Answer 2

這些失敗的長時間運行測試的問題是堆棧跟蹤在確定實際發生的事情時非常糟糕。我們確定這些故障的根本原因爲缺少網絡連接。
