Pros and cons of end to end testing tools

  |   0 评论   |   399 浏览

My background in test automation is based on using Selenium WebDriver and Java. Since JavaScript has been widely used for testing web applications, I have decided to investigate tools currently available on the market. I will use these tools to make different scripts and hence find their advantages and disadvantages.

I have investigated the following tools and syntax for automation:

  1. Selenium Webdriver + Java
  2. Selenium WebDriver + Cucumber + Java
  3. Selenium WebDriver + Jasmine syntax for JavaScript applications
  4. Selenium WebDriver + Mocha syntax for JavaScript applications
  5. Cypress
  6. Selenium WebDriver + Protractor
  7. Selenium WebDriver + NightWatch
  8. Selenium WebDriver + WebDriverIO

A Step By Step Guide to Tomcat Performance Monitoring

Monitoring the metrics and runtime characteristics of an application server is essential to ensure the adequate functioning of the applications running on that server, as well as to prevent or resolve potential issues in a timely manner.


As far as Java applications go, one of the most commonly used servers is Apache Tomcat, which will be the focus of this article.

Tomcat performance monitoring can be done either by relying on JMX beans or by using a dedicated monitoring tool like MoSKito or JavaMelody.

3 ways to start Appium Server from Java

When you start learning Appium or start writing your first test script with it, your initial approach (especially from a beginner’s point of view) would be to start and stop the Appium server manually. Initially, a lot of people start working with the GUI based Appium versions.

GUI versions of Appium are easy to use, and users can easily start and stop the Appium server manually using the controls provided in the tool. After some time, many people would download and install the latest versions of Appium, which most of the times would be a non-GUI version. And its still relatively easy to start and stop the non-GUI version of Appium manually.

Web性能优化:图片优化 有更新!

HTTP Archieve有个统计,图片内容已经占到了互联网内容总量的62%,也就是说超过一半的流量和时间都用来下载图片。从性能优化的角度看,图片也绝对是优化的热点和重点之一,Google PageSpeed或者Yahoo的14条性能优化规则无不把图片优化作为重要的优化手段,本文覆盖了Web图片优化的方方面面,从基本的图片格式选择、到尚未被广泛支持的响应式图片均有所提及。

Google Web Fundamentals的说法我很喜欢:

图片优化既是一门艺术,也是一门科学,图片优化是一门艺术,是因为单个图片的压缩不存在最好的特定性方案,而图片优化之所以是一门科学,是因为许多开发得很出色的方法和算法可以明显减小图片的大小。要找到图片的最优设置,需要按照许多维度进行认真分析:格式能力、编码数据内容、像素尺寸等。

SS、SSR链接解析,查看对应密码、端口、协议

网上有很多人会分享一些免费的 ss/ssr 免费账号,有的会直接把服务、端口、ip、协议等展示出来(对于这种,直接手动输入相应参数就可以了),有的则直接显示二维码(二维码更方便,直接用客户端软件扫一下就可以使用)。

不过,也有很多是直接以链接的形式展示出来,比如 ss://xxxxxssr://xxxx,对于这种链接的方式,复制链接后,然后直接使用ss 、ssr客户端软件导入链接即可。以 ssr 链接为例,假设有这么一个链接(以下的 ss ssr 链接都转载至 https://doub.io/sszhfx/)。
