摘要: 一個(gè)完整的自動(dòng)化測(cè)試框架體系包含以下幾個(gè)部分：1、自動(dòng)化測(cè)試框架；2、測(cè)試腳本以及測(cè)試數(shù)據(jù)管理；3、測(cè)試腳本的執(zhí)行管理系統(tǒng)；4、測(cè)試結(jié)果的顯示與分析系統(tǒng)。其中最重要的是自動(dòng)化測(cè)試框架部分。

摘要: JUnit
JUnit是由 Erich Gamma 和 Kent Beck 編寫(xiě)的一個(gè)回歸測(cè)試框架（regression testing framework）。Junit測(cè)試是程序員測(cè)試，即所謂白盒測(cè)試，因?yàn)槌绦騿T知道被測(cè)試的軟件如何（How）完成功能和完成什么樣（What）的功能。Junit是一套框架，繼承TestCase類，就可以用Junit進(jìn)行自動(dòng)測(cè)試了。

摘要: Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin?
For example, less command is located under /usr/bin directory. Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories?
In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories

摘要: 當(dāng)今互聯(lián)網(wǎng)的發(fā)展，已不是大魚(yú)吃小魚(yú)的時(shí)代，而是快魚(yú)吃慢魚(yú)的時(shí)代。互聯(lián)網(wǎng)產(chǎn)品的制勝原則就是一個(gè)字——“快”。在各種形態(tài)的產(chǎn)品研發(fā)中，我們始終貫徹如一的價(jià)值觀之一就是“快”，我們應(yīng)該如何來(lái)理解和詮釋“快”？又會(huì)從哪些方面來(lái)執(zhí)行貫徹這個(gè)原則呢？

摘要: 軟件測(cè)試的十二個(gè)誤區(qū)大體總結(jié)如下：
1) 測(cè)試人員不需要了解軟件開(kāi)發(fā)的知識(shí)：
這個(gè)很要命的，我們談到軟件測(cè)試人員未來(lái)的發(fā)展方向大致有：自動(dòng)化測(cè)試，性能測(cè)試，測(cè)試管理，項(xiàng)目經(jīng)理。這其中自動(dòng)化測(cè)試和性能測(cè)試包括項(xiàng)目管理，都會(huì)要求對(duì)軟件開(kāi)發(fā)有深入的理解，如何能設(shè)計(jì)一個(gè)好的自動(dòng)化框架，好的性能測(cè)試用例，如何管理一個(gè)開(kāi)發(fā)團(tuán)隊(duì)，這都需要我們?cè)谲浖_(kāi)發(fā)方面有所掌握。不單要掌握，而且要精通。此其一。
其二：如果不了解開(kāi)發(fā)知識(shí)，測(cè)試人員很容易被開(kāi)發(fā)人員牽著鼻子走，因?yàn)殚_(kāi)發(fā)人員隨便一忽悠，你如果不了解個(gè)中奧妙，你一個(gè)字也說(shuō)不上來(lái)。(以前我們討論 Cookie和Session，由于GoAhead不支持Session，只能用Cookie來(lái)控制，差點(diǎn)別開(kāi)發(fā)人員忽悠了)

摘要: 寫(xiě)在前面：寫(xiě)Android程序有一個(gè)很重要的原則，不阻塞UI線程。因此Android提供了5種方法來(lái)，讓一些耗時(shí)的作業(yè)在其它線程中執(zhí)行，然后把結(jié)果返回給UI線程，以免阻塞UI線程。

首先android的selector是在drawable/xxx.xml中配置的。

摘要: The Monkey is a command-line tool that that you can run on any emulator instance or on a device. It sends a pseudo-random stream of user events into the system, which acts as a stress test on the application software you are developing.
The Monkey includes a number of options, but they break down into four primary categories:
Basic configuration options, such as setting the number of events to attempt.
Operational constraints, such as restricting the test to a single packag

摘要: Programmers can configure logging either by creating loggers, handlers, and formatters explicitly in a main module with the configuration methods listed above (using Python code), or by creating a logging config file. The following code is an example of configuring a very simple logger, a console handler, and a simple formatter in a Python module:

摘要: The list below defines some of the basic terminology of the Android platform.
.apk file
Android application package file. Each Android application is compiled and packaged in a single file that includes all of the application's code (.dex files), resources, assets, and manifest file. The application package file can have any name but must use the .apk extension. For example: myExampleAppname.apk. For convenience, an application package file is often referred to as an ".apk".

摘要: 一、ASE(Android Scripting Environment)為Android系統(tǒng)帶來(lái)了腳本語(yǔ)言的技術(shù)，通過(guò)它我們可以編輯和執(zhí)行腳本，和腳本解釋交互。腳本可以訪問(wèn)多數(shù)Android API,目前有一個(gè)開(kāi)源項(xiàng)目叫做Scripting Layer for Android (SL4A) ，提供了對(duì)python,javaScript, Lua等腳本的支持。ASE主要通過(guò)兩種方式來(lái)訪問(wèn) Android API,一種是通過(guò)JSON-RPC來(lái)訪問(wèn),另外一種通過(guò)BeanShell（Java語(yǔ)言的動(dòng)態(tài)版本）直接訪問(wèn)Android API。SL4AL架構(gòu)如下圖：

1)
http://www.pythonchallenge.com/ 提供了不同level的Python題目，非常有趣的題目。做完一題后，把URL中的pc改為pcc可以看到上一題的答案
2)
http://projecteuler.net/ 里面有200多道題目，不要要求提交代碼，只要最終答案，提供用各種語(yǔ)言來(lái)解決問(wèn)題。這里（
http://dcy.is-programmer.com/posts/8750.html）有部分題目的答案
非常好玩，有興趣的朋友，快來(lái)試試吧
看看 project euler 的第一道題：
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
用 python 語(yǔ)言寫(xiě)出來(lái)是：
print sum(i for i in xrange(1, 1000) if i % 3 == 0 or i % 5 == 0)
This is the first edition of what is expected to become a recurring series on InfoQ. The idea behind this minibook is that a number of InfoQ articles and interviews which deal with a particular topic (in this case, REpresentational State Transfer, or REST) are combined together to provide a detailed exploration suitable for both beginners and advanced practitioners.

摘要: The Bloom filter, conceived by Burton Howard Bloom in 1970, is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set.False positivesare possible, but false negatives are not. Elements can be added to the set, but not removed (though this can be addressed with a counting filter). The more elements that are added to the set, the larger the probability of false positives

摘要: These posts have garnered a number of interesting comments. I want to address two of the negative ones in this post. Both are of the same general opinion that I am abandoning testers and that Google is not a nice place to ply this trade. I am puzzled by these comments because nothing could be further from the truth. One such negative comment I can take as a one-off but two smart people (hey they are reading this blog, right?) having this impression requires a rebuttal. Here are the comments:

摘要: One of the key ways Google achieves good results with fewer testers than many companies is that we rarely attempt to ship a large set of features at once. In fact, the exact opposite is often the goal: build the core of a product and release it the moment it is useful to as large a crowd as feasible, then get their feedback and iterate. This is what we did with Gmail, a product that kept its beta tag for four years. That tag was our warning to users that it was still being perfected. We removed

摘要: Android applications are, at least on the T-Mobile G1, limited to 16 MB of heap. It's both a lot of memory for a phone and yet very little for what some developers want to achieve. Even if you do not plan on using all of this memory, you should use as little as possible to let other applications run without getting them killed. The more applications Android can keep in memory, the faster it will be for the user to switch between his apps. As part of my job, I ran into memory leaks issues in Andr
