我正在尝试为我的一个项目获取 Sonar 报告。
我已经运行了mvn clean install
Running blah.blah.BlahTest1
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.016 sec
Running blah.blah.BlahTest2
Tests run: 3, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.078 sec
当我运行 mvn sonar:sonar 时，出现以下错误。

我不确定从哪里开始寻找。我尝试在谷歌中搜索找不到与我的问题类似的任何内容。
请帮助我了解可能需要查找的原因。
谢谢。

最佳答案
虽然我不是 Maven 专家，但我有实现，其中，在 Maven 生命周期中，我执行一些 JUnit 来查找代码覆盖率和 Sonar，当然。我正在附上我的 pom。也许这有帮助。

关于java - Sonar 测试用例失败，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31871868/
很好奇，就使用rubyonrails自动化单元测试而言，你们正在做什么？您是否创建了一个脚本来在cron中运行rake作业并将结果邮寄给您？git中的预提交Hook？只是手动调用？我完全理解测试，但想知道在错误发生之前捕获错误的最佳实践是什么。让我们理所当然地认为测试本身是完美无缺的，并且可以正常工作。下一步是什么以确保他们在正确的时间将可能有害的结果传达给您？ 最佳答案 不确定您到底想听什么，但是有几个级别的自动代码库控制:在处理某项功能时，您可以使用类似autotest的内容获得关于哪些有效，哪些无效的即时反馈。要确保您的提
我正在编写一个包含C扩展的gem。通常当我写一个gem时，我会遵循TDD的过程，我会写一个失败的规范，然后处理代码直到它通过，等等......在“ext/mygem/mygem.c”中我的C扩展和在gemspec的“扩展”中配置的有效extconf.rb，如何运行我的规范并仍然加载我的C扩展？当我更改C代码时，我需要采取哪些步骤来重新编译代码？这可能是个愚蠢的问题，但是从我的gem的开发源代码树中输入“bundleinstall”不会构建任何native扩展。当我手动运行rubyext/mygem/extconf.rb时，我确实得到了一个Makefile(在整个项目的根目录中)，然后当
我有一个围绕一些对象的包装类，我想将这些对象用作散列中的键。包装对象和解包装对象应映射到相同的键。一个简单的例子是这样的:classAattr_reader:xdefinitialize(inner)@inner=innerenddefx;@inner.x;enddef==(other)@inner.x==other.xendenda=A.new(o)#oisjustanyobjectthatallowso.xb=A.new(o)h={a=>5}ph[a]#5ph[b]#nil,shouldbe5ph[o]#nil,shouldbe5我试过==、===、eq?并散列所有无济于事。
我有一些Ruby代码，如下所示:Something.createdo|x|x.foo=barend我想编写一个测试，它使用double代替block参数x，这样我就可以调用:x_double.should_receive(:foo).with("whatever").这可能吗？ 最佳答案 specify'something'dox=doublex.should_receive(:foo=).with("whatever")Something.should_receive(:create).and_yield(x)#callthere
Sinatra新手；我正在运行一些rspec测试，但在日志中收到了一堆不需要的噪音。如何消除日志中过多的噪音？我仔细检查了环境是否设置为:test，这意味着记录器级别应设置为WARN而不是DEBUG。spec_helper:require"./app"require"sinatra"require"rspec"require"rack/test"require"database_cleaner"require"factory_girl"set:environment,:testFactoryGirl.definition_file_paths=%w{./factories./test/
我真的很习惯使用Ruby编写以下代码:my_hash={}my_hash['test']=1Java中对应的数据结构是什么？ 最佳答案 HashMapmap=newHashMap();map.put("test",1);我假设？ 关于java-等价于Java中的RubyHash，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.com/questions/22737685/
我遵循MichaelHartl的“RubyonRails教程:学习Web开发”，并创建了检查用户名和电子邮件长度有效性的测试(名称最多50个字符，电子邮件最多255个字符)。test/helpers/application_helper_test.rb的内容是:require'test_helper'classApplicationHelperTest在运行bundleexecraketest时，所有测试都通过了，但我看到以下消息在最后被标记为错误:ERROR["test_full_title_helper",ApplicationHelperTest,1.820016791]test
我已经构建了一些serverspec代码来在多个主机上运行一组测试。问题是当任何测试失败时，测试会在当前主机停止。即使测试失败，我也希望它继续在所有主机上运行。Rakefile:namespace:specdotask:all=>hosts.map{|h|'spec:'+h.split('.')[0]}hosts.eachdo|host|begindesc"Runserverspecto#{host}"RSpec::Core::RakeTask.new(host)do|t|ENV['TARGET_HOST']=hostt.pattern="spec/cfengine3/*_spec.r
我在app/helpers/sessions_helper.rb中有一个帮助程序文件，其中包含一个方法my_preference，它返回当前登录用户的首选项。我想在集成测试中访问该方法。例如，这样我就可以在测试中使用getuser_path(my_preference)。在其他帖子中，我读到这可以通过在测试文件中包含requiresessions_helper来实现，但我仍然收到错误NameError:undefinedlocalvariableormethod'my_preference'.我做错了什么？require'test_helper'require'sessions_hel
只是想确保我理解了事情。据我目前收集到的信息，Cucumber只是一个“包装器”，或者是一种通过将事物分类为功能和步骤来组织测试的好方法，其中实际的单元测试处于步骤阶段。它允许您根据事物的工作方式组织您的测试。对吗？ 最佳答案 有点。它是一种组织测试的方式，但不仅如此。它的行为就像最初的Rails集成测试一样，但更易于使用。这里最大的好处是您的session在整个Scenario中保持透明。关于Cucumber的另一件事是您(应该)从使用您的代码的浏览器或客户端的角度进行测试。如果您愿意，您可以使用步骤来构建对象和设置状态，但通常您
