可以看出ES Client用到了HttpClient的异步Client,我猜是用future实现同步返回响应结果,这个没仔细看,有错请指出。这里也回答我的自己的一个疑惑,ES Client是支持并发的。
package com.funtest.groovytest
import com.alibaba.fastjson.JSONObject
import com.funtester.es.ESClient
import com.funtester.frame.SourceCode
import com.funtester.frame.execute.FunQpsConcurrent
import java.util.concurrent.atomic.AtomicInteger
class ESC extends SourceCode {
static void main(String[] args) {
def client = new ESClient("127.0.0.1", 9200, "http")
def data = new JSONObject()
data.name = "FunTester"
data.age = getRandomInt(100)
def index = new AtomicInteger(0)
def test = {
data.put("time", index.getAndIncrement())
client.index("fun", "tt", data)
}
new FunQpsConcurrent(test, "ES添加数据").start()
}
}
如果想测试添加、删除功能,只需要把test闭包内容修改即可。
def test = {
data.put("time", index.getAndIncrement())
client.delete("fun", "tt", client.index("fun", "tt", data))
}
下面是搜索功能的性能测试用例:

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
