Question: How many combinations can a maximum of 16 of the five ABCDE balls be extracted repeatedly?
For example, there are five combinations of a B c d e which can be composed of one ball, A combination of 5 + 4 + 3 + 2 + 1 = 15 (repeated arrangement of BA and AB is considered as one)
Aa AB ac ad AE
Bb bc bd be
CC CD CE
Dd de
EE
The combination of three balls is (5 + 4 + 3 + 2 + 1) + (4 + 3 + 2 + 1) + (3 + 2 + 1) + (2 + 1) + 1 = 35

We all know that the most common functions in daily development are: compile, package, run JUnit testcase, and check the encoding specifications. Here is an ant template file for these most commonly used features, which will be shared with you.

Why is Page Object required?
Page Object (PO) is a common mode in the automated Acceptance Test of the interface. I want to discuss the necessity of Po with @ slot's nickname. I will express my point of view in this article.
The main value of Po is the encapsulation of interface interaction details, which enables the test case to focus more on the business rather than the Interface Details and improve the readability of the test case, this is actually very beneficial to the implementation of be
methodology of people, to introduce a colleague in a word:站在教学的角度来讲,我还是很推崇TDD的,TDD是一个很好的思维框架,如果非要教人一个思维框架的话就得教TDD,不然人会瞎碰,不思考,不总结,不结果导向,靠灵感编程,凭直觉设计,撞大运修bug。最糟糕的是因为没有好的习惯会接二连三的发生灵异现象。同一道题,习惯不好的人做,总能做出无数种新问题来。而且问题套问题,给他解决要浪费我半天时间,如果他学会了TDD出的错只在最近一个引入的变化里,就好纠正多了。甚至他自己都能纠正。The blogger is very sympathetic to the colleague's view, and the author thinks:tdd重要的不是测试代码本身,是解决问题的思维,也许可以泛化,哪怕没测试,如果能够做到快速验证,反馈,价值的稳定叠加,有足够信心,也未尝不可。也许你会说测试可以cover功能,那么如果只有这一点的话,我更喜欢BDD
On Sunday prior to the agile 2009 Conference, the third agile Alliance Function Testing seminar was held. Anyone interested in improving existing functional testing tools (relative to unit testing) can participate in the open space agenda. Participants included the creators and contributors of the following tools: Selenium, SWAT, cucumber, webtest, robotframework, and twist.
Because of the open space format, the outline and schedule of the Meeting were decided on site, and there were 3 time s
phing for automated testing, and finally it can be integrated with selenium to complete large-scale automated integration testing.
Selenium
Selenium is a tool for Web application testing. Selenium's test cases run directly in the browser, just as the real user is doing. Compared with the mainstream web Automation testing framework QTP, Ruby-based Watir, selenium supports a variety of browsers such as IE, Mozilla Firefox, automatic recording scripts and the automatic generation of Java, C #,

When we look at the code, we often see @override appear in the previous line of the function. Many people do not understand what this means.
In fact, @override is telling the compiler that your method is a method of overloading the parent class. What is the effect of doing so. In this case, the compiler will look in the parent class method to see if there is a method to determine if you are overloaded.
For example, the parent has a method of add (), when you want to overload, written as
; beforeEach !-> console.log 'beforeEach file test!' afterEach !-> console.log 'afterEach File test!' describe '#readFile()', !-> can 'should read test.ls without error', !(done)-> fs.readFile 'test.ls', !(err)-> if err throw err done! can 'should read test.js without error', !(done)-> fs.readFile 'test.js', !(err)-> if err throw err done!
