    近年来,大众参与的软件创新与创业活动已经成为网络时代软件开发和应用的新形态,正在快速改变着全球软件创新模式和软件产业格局。系统地揭示这种网构化软件开发形态背后蕴含的核心机理,构建适应我国自主发展特点的软件创新生态环境,是当前我国软件产业发展面临的重大历史机遇。


    在此背景下,国防科技大学、北京大学、北京航空航天大学、中科院软件所等单位合作开展了基于网络的软件开发群体化方法与技术研究,揭示了以大众化协同开发、开放式资源共享、持续性可信评估为核心的互联网大规模协同机理,与软件开发工程化方法相结合,系统地提出了基于网络的软件开发群体化方法,形成了网构化软件开发和运行技术体系,构建了可信的国家软件资源共享与协同生产环境(简称“Trustie”,中文简称“确实”)。


    Trustie团队就是在此过程中不断成长的一个勇于探索、勇于创新、勇于挑战的科研人员组成的群体,其中包括大学老师、工程师、研究生和本科生。


    Trustie团队揭示了以大众化协同开发、开放式资源共享、持续性可信评估为核心的互联网大规模协同机理,与软件开发工程化方法相结合,系统地提出了基于网络的软件开发群体化方法,产生了三方面技术发明,构建了可信的国家软件资源共享与协同生产环境(简称“Trustie”,中文简称“确实”),形成授权发明专利26项、软件著作权38项、技术标准(或提案)7项,发明人受邀赴国内外重要学术会议做主题报告20余次,如图1。

上述课堂的作业都加入了题库,但在新课程里选的时候,报不能选,因为是“我收到的作业”


加入题库的题,应该是可以直接选用的,请排查一下解决后马上上线

Ruby Intro


This 3-part homework gives some basic practice in Ruby as well as getting you accustomed to making testing a regular part of your workflow.


Learning Goals


After completing this assignment, you will know how to:

  • Write simple code that uses basic constructs in the Ruby language, including methods and arguments, conditionals, string and array manipulation, regular expressions, and basic object-oriented programming mechanisms
  • Understand the Ruby project conventions for where code files and test files are located in a project's directory hierarchy
  • Run individual tests or suites of tests using the RSpec unit testing tool
  • Understand the basic syntax of RSpec unit tests


Overview


The repo for this assigment follows a fairly standard Ruby convention for codebases: the code files are stored in lib/ and the test files are stored in spec/. (We use the RSpec unit-testing framework; if we were using Ruby's default framework, known as Test::Unit, the test files would be under test/.)

We've placed "starter code" in lib/ruby_intro.rb; when you're all done, you can submit to Trustie.


However, you can test each of the 3 parts separately. The files spec/part[123]_spec.rb contain RSpec tests for each of the three parts. For example, to test your answers to Part 1, say rspec spec/part1_spec.rb. rspec with no arguments runs the tests in all the files spec/*_spec.rb.

  • The line numbers in the RSpec error report will give you guidance as to which tests failed. (You can check the RSpec documentation to see how the .rspec file can be used to customize the output format.)

To ensure you have the rspec gem installed you need bundler and can then run bundle install like so (if you accidentally do not use c9 ide):

$ gem install bundler $ cd hw-ruby-intro $ bundle

When the above completes successfully you'll have RSpec installed and can run rspec from the command line to test your code.


Before starting your homework, please refer to the recommanded workflow as below for this and future assignment:

  • Create a project with the name hw-ruby-intro in your Trustie workspace
  • Create a project repository with the name hw-ruby-intro in the setting page of the project
  • Link the project repository to this assignment
  • Clone the homework repository to your c9 ide workspace or anywhere you coding


git clone https://github.com/saasbook/hw-ruby-intro


  • Do your homework and test your solution


  • Commit change to your local git repository
  • Push your local repository at c9 workspace to your Trustie project repository
  • Submit your homework assignment in Trustie

Please refer to the Trustie user guide for creating project, repository, and using basic git command to manage your code repositories.

1. Arrays, Hashes, and Enumerables

Check the Ruby 2.x documentation on Array, Hash and Enumerable as they could help tremendously with these exercises. :-)

  1. Define a method sum(array) that takes an array of integers as an argument and returns the sum of its elements. For an empty array it should return zero. Run associated tests via:                         

    $ rspec spec/part1_spec.rb:5


  2. Define a method max_2_sum(array) which takes an array of integers as an argument and returns the sum of its two largest elements. For an empty array it should return zero. For an array with just one element, it should return that element. Run associated tests via:

    $ rspec spec/part1_spec.rb:23


  3. Define a method sum_to_n?(array, n) that takes an array of integers and an additional integer, n, as arguments and returns true if any two elements in the array of integers sum to n.sum_to_n?([], n) should return false for any value of n, by definition. Run associated tests via:

    $ rspec spec/part1_spec.rb:42


You can check your progress on the all the above by running $ rspec spec/part1_spec.rb.


2. Strings and Regular Expressions

Check the documentation on String and Regexp as they could help tremendously with these exercises. :-)

  1. Define a method hello(name) that takes a string representing a name and returns the string "Hello, " concatenated with the name. Run associated tests via:

    $ rspec -e '#hello' spec/part2_spec.rb


  2. Define a method starts_with_consonant?(s) that takes a string and returns true if it starts with a consonant and false otherwise. (For our purposes, a consonant is any letter other than A, E, I, O, U.) NOTE: be sure it works for both upper and lower case and for non letters! Run associated tests via:

    $ rspec -e '#starts_with_consonant?' spec/part2_spec.rb


  3. Define a method binary_multiple_of_4?(s) that takes a string and returns true if the string represents a binary number that is a multiple of 4. NOTE: be sure it returns false if the string is not a valid binary number! Run associated tests via:

    $ rspec -e '#binary_multiple_of_4?' spec/part2_spec.rb


You can check your progress on the all the above by running $ rspec spec/part2_spec.rb.


3. Object Oriented Basics

Define a class BookInStock which represents a book with an ISBN number, isbn, and price of the book as a floating-point number, price, as attributes. Run associated tests via:

$ rspec -e 'getters and setters' spec/part3_spec.rb


The constructor should accept the ISBN number (a string, since in real life ISBN numbers can begin with zero and can include hyphens) as the first argument and price as second argument, and should raise ArgumentError(one of Ruby's built-in exception types) if the ISBN number is the empty string or if the price is less than or equal to zero. Include the proper getters and setters for these attributes. Run associated tests via:

$ rspec -e 'constructor' spec/part3_spec.rb


Include a method price_as_string that returns the price of the book formatted with a leading dollar sign and two decimal places, that is, a price of 20 should format as "$20.00" and a price of 33.8 should format as "$33.80". Run associated tests via:

$ rspec -e '#price_as_string' spec/part3_spec.rb


You can check your progress on the all the above by running rspec spec/part3_spec.rb.


More Challenges

  • Try getting setup with an automated test framework such as guard or autotest. Guard or AutoTest can be set up so that they will run all the tests in spec/, but every time you edit and save your code file, the tests are automatically re-run, so you don't have to run them manually. As we'll see later, this is the "watch the test fail" part of the TDD or test-driven process of development: write the tests before you write the code, watch the test fail, fill in the code and save the code file, then watch the test pass!
