          Java開(kāi)源測(cè)試工具

               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(lèi),就可以用Junit進(jìn)行自動(dòng)測(cè)試了。

          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?

          【轉(zhuǎn)載】軟件測(cè)試的十二個(gè)誤區(qū)

               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)  閱讀全文

          Glossary of Android

               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".

          Python中的Closure


          #定義:如果在一個(gè)內(nèi)部函數(shù)里,對(duì)在外部作用域(但不是在全局作用域)的變量進(jìn)行引用,那么內(nèi)部函數(shù)就被認(rèn)為是閉包(closure)
          分解來(lái)說(shuō),包含下面3個(gè)條件:
          1) 需要函數(shù)嵌套, 就是一個(gè)函數(shù)里面再寫(xiě)一個(gè)函數(shù).
          2) 外部函數(shù)需要返回一個(gè)內(nèi)部函數(shù)的引
          3) 外部函數(shù)中有一些局部變量, 并且, 這些局部變量在內(nèi)部函數(shù)中有使用
          一些概念:
          1)自由變量: 外部函數(shù)中定義的局部變量, 并且在內(nèi)部函數(shù)中被使用
          2) 閉包: 那個(gè)使用了自由變量并被返回的內(nèi)部函數(shù)就稱(chēng)為閉包

          #支持閉包的語(yǔ)言有這樣的特性:
          1)函數(shù)是一階值(First-class value),即函數(shù)可以作為另一個(gè)函數(shù)的返回值或參數(shù),還可以作為一個(gè)變量的值
          2)函數(shù)可以嵌套定義,即在一個(gè)函數(shù)內(nèi)部可以定義另一個(gè)函數(shù)

          #代碼示例

           1def counter(start_at=0):
           2    count = [start_at]
           3    def incr():
           4        count[0] += 1   #對(duì)局部變量的引用
           5        return count[0]
           6    return incr  #返回一個(gè)函數(shù)對(duì)象
           7

          10    c = counter(3)
          11    print type(c)

          Bloom Filter

               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
