Poltergeist / PhantomJS在Gitlab CI中崩溃
背景：
直到最近，我的测试套件还没有处理任何JS功能。 我开始只在我的机器上使用selenium-webdriver javascript驱动程序和firefox 47.0.1，没有任何问题。 然后我转移到支持PhantomJS作为我的JavaScript驱动程序的poltergeist 。 我不得不对一些破碎的测试做一些改动，但是非常享受转换，并且在PhantomJS / poltergeist上“销售”。
预期行为：
我希望测试能够像我在机器上那样传递给我的Gitlab-ci（嘿，我们可以梦想），也许需要一些配置调整。
版本：
Ruby - 2.3.1
Rails - 5.0.0.1
poltergeist - 1.12.0
rspec - 3.5.0
rspec-rails - 3.5.1
水豚 - 2.11.0
cliver - 0.3.2
factory_girl_rails - 4.7.0
phantomjs - 2.1.1（在我的机器和CI服务器上）
水豚配置：
require 'capybara/rspec'
require 'capybara/poltergeist'
Capybara.default_driver = :rack_test
Capybara.register_driver :poltergeist do |app|
options = {
:js_errors => false,
:timeout => 360,
:phantomjs_options => ['--load-images=no', '--ignore-ssl-errors=yes', '--disk-cache=false']
}
Capybara::Poltergeist::Driver.new(app, options)
end
Capybara.javascript_driver = :poltergeist
DatabaseCleaner配置
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
end
config.before(:each) do
DatabaseCleaner.strategy = Capybara.current_driver == :rack_test ? :transaction : :truncation
DatabaseCleaner.clean
DatabaseCleaner.start
end
config.after(:each) do |example|
puts 'RAM USAGE: ' + `pmap #{Process.pid} | tail -1`[10,40].strip
if defined?(page)
Capybara.reset_sessions!
page.driver.restart
end
DatabaseCleaner.clean
end
实际行为/回溯：
1. 失败的测试，PhantomJS崩溃
在我忘记了所有记忆之前，为了获得完整的--fail-fast我使用了rspec --fail-fast选项在我的第一个错误中反馈结果。 这是我回来的：

另外，在我的gitlab-ci.yml文件中，如果我在before_script调用phantomjs --version ，我会收到：
QXcbConnection: Could not connect to display
PhantomJS has crashed. Please read the bug reporting guide at
<http://phantomjs.org/bug-reporting.html> and file a bug report.
任何帮助，将不胜感激。
2. 内存爆发已解决：请参阅更新2
即使增加了服务器上的内存容量，测试也会耗尽内存，并在测试套件完成之前崩溃测试套件。 要在每次测试后跟踪我的RSpec配置中的内存使用情况，请运行：
puts '在此处输入代码RAM USAGE: ' + PMAP＃{Process.pid} | 尾巴-1 [10,40].strip
内存在模型测试中受到的影响最小，但在集成测试下迅速增长。 像这样：
Model Test-
RAM USAGE: 567800K
Model Test-
RAM USAGE: 567800K
Model Test-
RAM USAGE: 567800K
Model Test-

Model Test-
RAM USAGE: 568652K
Model Test-
RAM USAGE: 568788K
First Feature Test:

并从那里吹起来。
为了解决这个问题，我已经确保使用适当的DatabaseCleaner策略，也可以通过尝试诸如Capybara.reset_sessions!等工具来循环使用Capybara.reset_sessions! ， Capybara.current_session.driver.quit ， page.driver.quit ， page.driver.restart没有真正的快乐。
更新：

1.崩溃
Gitlab支持已经建议调查我们的软件包和依赖关系是否导致PhantomJS出现无头的情况。 我们现在正在调查。
2.记忆
我已经针对几个不同的迭代运行了一个内存跟踪器，它似乎只是简单地启用我们的js: true使用javascript驱动程序进行js: true功能测试，以消耗内存，从1G进行大约1,750次测试，超过我们的4G限制在1,800-1,850测试。 我相信，这似乎发生在无论是selenium-webdriver poltergeist作为js司机。
更新2：
下午11:45 UTC，16/12/16
1.崩溃
仍在等待我们的服务器上正确安装软件包。 如果这是问题，将更新并奖励答案。
2.记忆
在我们正在迁移到Javascript驱动程序启用的一批测试的分支上，加速测试的部分配置实现了一个DeferredGarbageCollector，其中包含吞噬内存的设置。 PhantomJS和Poltergeist不会泄漏。 解决了
http://github.com/ariya/phantomjs/issues/14240是PhantomJS崩溃的原因 - Ubuntu发布的PhantomJS版本需要X才能运行。
下载官方发布版本并使用它来解决崩溃问题。
您可能希望将内存问题作为单独问题添加。
