Defect Taxonomies Section IV Supporting Technologies

However, since 2000, many researchers have started to actively use software engineering classification models to classify usability defects. One of the most prominent approaches is the adoption of a cause-effect model. In Pre-CUP, usability evaluators use nine attributes to describe usability defects in detail. Once the usability defects have been fixed, the developers record four attributes in Post-CUP. For example, technical information about defect removal activity, failure qualifier, expected phase, and frequency are difficult to obtain, especially for those who have limited usability-technical knowledge.

Despite reported benefits, Kubernetes installations are susceptible to security defects, as it occurred for Tesla in 2018. Understanding how frequently security defects appear in Kubernetes installations can help cybersecurity researchers to investigate security-related vulnerabilities for Kubernetes and generate security best practices to avoid them. In this position paper, we first quantify how frequently security defects appear in Kubernetes manifests, i.e., configuration files that are use to install and manage Kubernetes. Next, we lay out a list of future research directions that researchers can pursue.We apply qualitative analysis on 5,193 commits collected from 38 open source repositories and observe that 0.79% of the 5,193 commits are security-related. Based on our findings, we posit that security-related defects are under-reported and advocate for rigorous research that can systematically identify undiscovered security defects that exist in Kubernetes manifests. We predict that the increasing use of Kubernetes with unresolved security defects can lead to large-scale security breaches.

A Formal Taxonomy to Improve Data Defect Description

This information could help software developers to understand the reason why a user considers the problem as a valid usability defect. Based on these definitions, the two keywords refer to the ability of users to recognize and understand possible actions based on visual cues of user interface. The unclear separation between the keywords can lead to misclassification of defects that will eventually affect the identification of root cause and similar resolution strategies.

In this article, we summarize recent research in the IaC domain by discussing key quality issues, specifically security and maintainability smells, that may arise in an IaC script. We also mine open-source repositories from three organizations and report our observations on the identified smells. Furthermore, we also synthesize recommendations from the literature for software practitioners that could improve the quality of IaC scripts. Software development teams dealing with large computing infrastructure can get benefited from the actionable recommended practices.

Your Taxonomy

We validate our approach on a comprehensive dataset of model transformations. No taxonomy has a one-fits-all property – it’s likely to require some modifications to fit the product your testing for. Consider the defects you want to target and their level of detail.

In addition, researchers in the domain may use this study to find opportunities to improve the state-of-the-art. At the outset, a defect taxonomy acts as a checklist, reminding the tester so that no defect types are forgotten. Later, the taxonomy can be used as a framework to record defect data. Subsequent analysis of this data can help an organization understand the types of defects it creates, how many , and how and why these defects occur. Then, when faced with too many things to test and not enough time, you will have data that enables you to make risk-based, rather than random, test design decisions. In addition to taxonomies that suggest the types of defects that may occur, always evaluate the impact on the customer and ultimately on your organization if they do occur.

Impact of End User Human Aspects on Software Engineering

Poorly written IaC scripts impact various facets of quality and, in turn, may lead to serious consequences. Many of the ill-effects can be avoided or rectified easily by following recommendations derived from research and best practices gleaned from experience. While researchers have investigated methods to improve quality aspects of Puppet scripts, such research needs to be summarized and synthesized for industry practitioners.

  • Note how this taxonomy could be used to guide both inspections and test case design.
  • But, if a user experiences the slowness of retrieving the search results and is frustrated by a delay, in addition to performance it also affects usability.
  • With little information, the functionality and usability issues were difficult to distinguish.
  • Now, we like to think of defect-based testing as having radar for a certain kind of bug .

Keep your users (that’s you and other testers in your organization) in mind. Later, look for natural hierarchical relationships between items in the taxonomy. Combine these into a major category with subcategories underneath.

Project Level Taxonomies

Usability is one of the prominent software quality characteristics that measures the understandability, learnability, operability and attractiveness of the software products . In the context of community open source software in which no specific software development processes were carried out, usability activities are often ignored. Volunteers are more focused on functionality and features rather than appearance, design aesthetic, and how people will use the products . As a result, open source projects often have poor interfaces and complex user interaction , . Infrastructure as Code scripts, such as Puppet scripts, provide practitioners the opportunity to provision computing infrastructure automatically at scale.

Defects that have low impact may not be worth tracking down and repairing. Usability engineering needs to make it feasible to be used in open source software development. The use of the taxonomy has been validated on five real cases of usability defects. However, evaluation results using the OSUDC were only moderately successful.

Whittaker s How to Break Software Taxonomy

One of the first defect taxonomies was defined by Boris Beizer in Software Testing Techniques. In software test design we are primarily concerned with taxonomies of defects, ordered lists of common defects we expect to encounter in our testing. Each of these characteristics and subcharacteristics suggest areas of risk and thus areas for which tests might be created. An evaluation of the importance of these characteristics should be undertaken first so that the appropriate level of testing is performed.

If you had a similar software testing project you can get additional inspiration from it. Usually, a decision has to be made between the level of detail and the redundancies in the list. Covering array generation is the core task of Combinatorial interaction testing , which is widely used to discover interaction faults in real-world systems. Considering the universality, constrained covering array generation is more in line with the characteristics of applications, and has attracted a lot of researches in the past few years.

Классификация дефектов (Defect Taxonomy)

Instead of using the standard requirements docs or the use cases, we use the defects to base test cases. A defect taxonomy is a method of gathering indications of problem areas. To create your own taxonomy, first start with a list of key concepts. Make sure the items in your taxonomy are short, descriptive phrases.
