Base case is where Recursion ends. So, the nomenclature seems to be totally confused, even though corner case seems to mean something a bit different (a combination of values) than edge and boundary cases, which are definitely synonymes. It's probably safe to say that edge, corner, and boundary cases are the same thing in common speech.
May 1, 2011 · An "edge" has two meanings, and both are relevant when it comes to edge cases. An edge is either an area where a small change in the input leads to a large change in the output, or the end of a range. So, to identify the edge cases of an algorithm, I first look at the input domain. Its edge values could lead to edge cases of the algorithm.
May 7, 2021 · An edge case is usually defined as what Wikipedia would say, An edge case is a problem or situation that occurs only at an extreme (maximum or minimum) operating parameter. For example, a stereo speaker might noticeably distort audio when played at maximum volume, even in the absence of any other extreme setting or condition.
However, I'd note that there are two types of edge cases: business requirement edge cases ("If we order 27 left trainers and 28 right trainers that order is probably wrong") which should be dealt with in the project requirements, and actual coding edge cases (dealing with invalid inputs, constantly iterating through lists when a hashset would be more sensible speed-wise when the set gets ...
Jan 25, 2013 · I can imagine a[n admittedly poorly designed] system where there are two edges from one statement to the next. In such a case, if one traverses only one edge then they have statement coverage but not branch coverage. They may be functionally the same (in most cases, at least) but there is a distinction. –
May 25, 2017 · Here is an edge case for defining a getter following SRP and DRY principles: in MVC pattern the view components could be backed by beans encapsulating information to be displayed, those beans could include a type of getter referred by synthetic getter string of words that returns a combination of properties it encapsulates or combination of properties of other beans it encapsulates.
Jul 13, 2018 · First, I look for the edge cases. These are places where the behavior changes. In your case, behavior changes at several points along the sequence of positive integer days. There is an edge case at zero, at one, at seven, etc. I would then write test cases at and around the edge cases.
Jun 8, 2016 · After your testing (and thank you for testing by the way!), send the dev a list of discovered issues. The fixing of those issues will go against the "fixing edge cases" condition of satisfaction. If anything remains unfixed or is discovered too late, decide whether the story needs to be pushed based on whether the use case can be fulfilled.
Apr 25, 2017 · I had a similar case where I wanted to distinguish different meanings of some integer values, and forbid implicit conversions between them. I wrote a generic class like this: template <typename T, typename Meaning> struct Explicit { //! Default constructor does not initialize the value. Explicit() { } //! Construction from a fundamental value.
Jun 16, 2020 · 6-10. [4] Let G = (V,E) be an undirected graph. A set F ⊆ E of edges is called a feedback-edge set if every cycle of G has at least one edge in F. (b) Suppose that G is a weighted undirected graph with positive edge weights. Design an efficient algorithm to find a minimum-weight feedback-edge set.
