Oracle - Hit/Miss Ratios
Oracle - Hit/Miss RatiosHere are some scripts related to Hit/Miss Ratios .Buffer Hit RatioBUFFER HIT RATIO NOTES:Consistent Gets - The number of accesses made to the block buffer to retrieve data in a consistent mode. DB Blk Gets - The number of blocks accessed via single block gets (i.e. not through the consistent get mechanism). Physical Reads - The cumulative number of blocks read from disk. Logical reads are the sum of consistent gets and db block gets. The db block gets statistic value is i

However, our intuition – backed by research and empirical evidence – is that unnecessarily complex and convoluted code, written by
认识p-unit:一款开源的性能测试框架
认识p-unit:一款开源的性能测试框架来源: AppFuse中文社区 http://www.ibm.com/developerworks/cn/java/j-lo-punit/index.htmlp-unit 是一款开放源码的性能测试框架,和 JUnit 不同,JUnit 关注的是测试案例的正确性,而 p-unit 不仅关注测试案例的正确性,还收集测试案例的性能参数,默认情况下,p-unit 收集测试案例的时间和内存消耗情况,可以产生文件,图片,和 PDF 格式的报表。此外,p-unit 还支持参数化测试,多线程测试以及不同 Java 虚拟机性能之间的比较。p-unit 简介或许我们已经习惯了使用 JUnit 来写单元测试来保证代码质量(
QA and Testing Interview Questions
When interviewing for a QA or Testing position, it's important to be honest. Hiring managers want to know what you know, what you can do, and what you are like. And nobody wants to hire a liar.As a hiring manager, I can tell if you are stretching the truth - particularly if you are just repeating simple definitions to complex concepts. If you are asked about QA or Testing terms that aren't familar to you, tell the interviewer that you haven't heard of those terms, then ask what they mean. Sinc

WinRunner - As a GUI based load testing tool
We use WinRunner as a load testing tool operating at the GUI layer as it allows us to record and playback user actions from a vast variety of user applications as if a real user had manually executed those actions. We use WinRunner in addition to LoadRunner when we want to record user experience response time. Visit mercuryinteractive.com/products/WinRunner/ for detailed information on WinRunner.http://www.loadtest.com.au/Technology/winrunner.htmThe following diagram shows how a GUI layer testin
Standard WinRunner Functions
This helps me select functions quickly by type of object and then by purpose. Add the function prefix to the suffixes inside each cell. I am working now to create sample scripts that demo these functions in use.http://www.wilsonmar.com/1wrfuncs.htmTopics this page: OS Functions File Functions COM Functions Window Functions Text Controls Navigation Controls Special Controls String Functions CSO Libraries Custom Controls Function Libraries Generic Custom Functions Naming Conventions Your comments

Three Reasons To Consider Being a Test Developer
Three Reasons To Consider Being a Test Developer When it comes to careers in the world of software most people think of programmers or what are more formally known as developers. Developers are the people who write the software which is consequently sold or utilized by the organization. I’ll call them dev-developers to distinguish them from test developers. Sometimes people will also think of testers. Testers are the people who don’t program but run the software written by devel
Crap4J力求通过算法判定代码质量http://www.crap4j.org/
Crap4J力求通过算法判定代码质量Crap4J这个新项目的目标非常清晰: 现在没有一种特别简单的,100%准确并且客观的方法来判定一段代码是否糟透了。不过研究和经验都能证明我们的直觉:那些由其他人写的过于复杂和曲折的代码往往就是那些让人说出“这简直是垃圾”的代码。如果看这段代码的人将来还要负责维护这段代码,那么他的反应往往就会变成“有没有搞错!” 但光是抱怨还不够,我们需要更精确的测量。Crap4j根据复杂性和测试覆盖率得出了一个数值指标。 给定任意Java方法m,m的CRAP值如下式计算: CRAP(m) = comp(m)^2 * (1 - cov(m)/100
Approaches to Performance Testing
Approaches to Performance Testinghttp://dev2dev.bea.com/pub/a/2005/09/performance_testing.htmlAbstractThere are many different ways to go about performance testing enterprise applications, some of them more difficult than others. The type of performance testing you will do depends on what type of results you want to achieve. For example, for repeatability, benchmark testing is the best methodology. However, to test the upper limits of the system from the perspective of concurrent user load, capa
