Agnostic Programming: Learning to Design and Test Basic by Kinga Laura Dobolyi PDF

By Kinga Laura Dobolyi

Agnostic Programming: studying to layout and attempt uncomplicated Programming Algorithms is written for novices who are looking to examine simple programming options with out the main points of any specific programming language. instead of an in-depth dialogue of programming syntax and pointless definitions, this brief publication introduces the center, foundational programming constructs with a test-driven method. brief, yet difficult programming routines are discovered on the finish of each bankruptcy. an exceptional first programming ebook for college kids who will proceed to software in a number of languages, with a heavy concentrate on challenge fixing and checking out.

Sample text

Let’s say each person gains points for stability indicators such as having a high GPA, and loses points for conflict indicators such as messiness. Although, theoretically, a person could have a very low number, or a very high number, our algorithm might only care about the cases when they have a negative score, cases when they have a score of zero, a score of one, or more than one. For example, we wouldn’t just want to average the scores for two people and recommend they be roommates if the result is non-negative; you might have a messy person put together with a clean person, which is uncomfortable for the latter.

Therefore, we will supplement all of our test suites with these boundary test cases. This is still just a flavor of input domain characterization, where we happen to have even finer granularity for our partitions to include new partitions that are the boundaries or edges of existing partitions. Let’s try it. Exercise: What would be a boundary input for the partitions of equilateral and isosceles triangles? Answer: What this question is asking is, given our integer domain space, what is the isosceles triangle that looks the most similar to an equilateral triangle (since we can’t have it the other way around)?

Why are we talking about testing code, before we have written any? Because, ideally, software testing should begin before code was written: this is called test driven development. Yes, tests should be written before you start to write code (or pseudocode, which is how we will refer to our ordered steps of solutions from now on). For example, imagine you are responsible for finding a caterer to provide food for your neighbor’s summer barbecue. Ironic, as, if you recall correctly, they borrowed your grill over a year ago…but hey, it’s free food, and you don’t want to get stuck eating tepid corn-from-a-can and reheated mystery meat.
