Poltergeist/PhantomJS 在 Gitlab 中崩溃 CI
Poltergeist/PhantomJS crashing in Gitlab CI
背景：
我的测试套件直到最近才处理任何 JS 功能。我开始了
仅在我的机器上有 selenium-webdriver javascript driver 和 firefox 47.0.1
没有问题。然后我迁移到 poltergeist 支持 PhantomJS 作为
我的 javascript driver。我不得不对一些失败的测试进行一些更改，但是
非常喜欢转换，我是 'sold' PhantomJS/poltergeist。
预期行为：
我预计测试会在我的 Gitlab-ci 上通过，就像在我的机器上一样
（嘿，我们可以做梦），可能需要一些配置调整。
版本：
Ruby - 2.3.1
Rails - 5.0.0.1
闹鬼 - 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
数据库清理器配置
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 Behavior/Backtraces:
1。 测试失败，PhantomJS 崩溃
为了在我耗尽所有内存之前获得失败测试的完整堆栈跟踪，我
在我第一次出错时使用 rspec --fail-fast 选项为我返回结果。
这是我返回的：

如有任何帮助，我们将不胜感激。
2。 内存爆炸 已解决：请参阅更新 2
测试会耗尽内存，即使我们增加了内存容量
服务器，并在测试套件完成之前使测试套件崩溃。跟踪内存使用情况
在我的 RSpec 配置中，每次测试后我 运行:
puts '在此处输入代码RAM USAGE: ' +pmap #{Process.pid} |尾巴-1[10,40].strip
内存在模型测试下影响最小，但增长迅速
在集成测试下。像这样：

然后从那里爆炸。
为了处理这个问题，我确保使用适当的 DatabaseCleaner 策略，
还通过尝试 Capybara.reset_sessions! 等工具循环
Capybara.current_session.driver.quit、page.driver.quit、page.driver.restart
没有真正的快乐。
更新：
世界标准时间下午 5:06，15/12/16
1。崩溃
Gitlab 支持建议调查我们的包和依赖项是否导致 PhantomJS 出现 non-headless 情况。我们正在对此进行调查。
2。内存
我已经 运行 了一个针对几个不同迭代的内存跟踪器，它似乎只是通过 javascript driver 启用我们的 js: true 功能测试消耗内存，从 1G 进行大约 1,750 次测试到超过我们的 4G 限制进行 1,800-1,850 次测试。我相信，这似乎发生在 selenium-webdriver 或 poltergeist 作为 js driver 的情况下。
更新 2：
UTC 时间 2016 年 16 月 12 日下午 11:45
1。崩溃
仍在等待在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。内存
在我们迁移到 Javascript-driver 启用的测试批次的 b运行ch 上，加速测试的部分配置实现了 DeferredGarbageCollector，它的设置吞噬了记忆。 PhantomJS 和 Poltergeist 没有泄漏。 已解决
http://github.com/ariya/phantomjs/issues/14240 是导致 PhantomJS 崩溃的原因 - Ubuntu 发布的 PhantomJS 版本需要 X 到 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添加为一个单独的问题。
背景：
我的测试套件直到最近才处理任何 JS 功能。我开始了
仅在我的机器上有 selenium-webdriver javascript driver 和 firefox 47.0.1
没有问题。然后我迁移到 poltergeist 支持 PhantomJS 作为

此外，在我的 gitlab-ci.yml 文件中，如果我在 before_script 中调用 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.
如有任何帮助，我们将不胜感激。
2。 内存爆炸 已解决：请参阅更新 2
测试会耗尽内存，即使我们增加了内存容量 服务器，并在测试套件完成之前使测试套件崩溃。跟踪内存使用情况 在我的 RSpec 配置中，每次测试后我 运行:
puts '在此处输入代码RAM USAGE: ' +pmap #{Process.pid} |尾巴-1[10,40].strip
内存在模型测试下影响最小，但增长迅速 在集成测试下。像这样：

然后从那里爆炸。
为了处理这个问题，我确保使用适当的 DatabaseCleaner 策略，
还通过尝试 Capybara.reset_sessions! 等工具循环
Capybara.current_session.driver.quit、page.driver.quit、page.driver.restart
没有真正的快乐。

1。崩溃
Gitlab 支持建议调查我们的包和依赖项是否导致 PhantomJS 出现 non-headless 情况。我们正在对此进行调查。
2。内存
我已经 运行 了一个针对几个不同迭代的内存跟踪器，它似乎只是通过 javascript driver 启用我们的 js: true 功能测试消耗内存，从 1G 进行大约 1,750 次测试到超过我们的 4G 限制进行 1,800-1,850 次测试。我相信，这似乎发生在 selenium-webdriver 或 poltergeist 作为 js driver 的情况下。

1。崩溃
仍在等待在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。内存
在我们迁移到 Javascript-driver 启用的测试批次的 b运行ch 上，加速测试的部分配置实现了 DeferredGarbageCollector，它的设置吞噬了记忆。 PhantomJS 和 Poltergeist 没有泄漏。 已解决
http://github.com/ariya/phantomjs/issues/14240 是导致 PhantomJS 崩溃的原因 - Ubuntu 发布的 PhantomJS 版本需要 X 到 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添加为一个单独的问题。
