Continuous Testing, Quality, Security, and Feedback

Principles of Continuous Testing, Quality, Security, and Feedback

This chapter explains how the continuous strategies are essential for digital transformations that utilize continuous development practices known as Agile, continuous delivery practices known as DevOps and DevSecOps, and continuous operations practices known as Site Reliability Engineering (SRE).

In this chapter, we’ll cover the following main topics:

  • Introducing continuous testing, continuous quality, continuous security, and continuous feedback
  • Defining continuous testing, quality, security, and feedback
  • The guiding principles and pillars of continuous testing
  • The guiding principles and pillars of continuous quality
  • The guiding principles and pillars of continuous security
  • The guiding principles and pillars of continuous feedback

Defining continuous testing, quality, security, and feedback

This section explains the importance of defining continuous testing, quality, security, and feedback and the challenges associated with doing so, followed by practical definitions for continuous testing, quality, security, and feedback.

The need for definitions of testing, quality, security, and feedback

There are no standard definitions for continuous testing, quality, security, and feedback, just as there are no standard definitions for DevOps, DevOps, or SRE. However, defining continuous testing, quality, security, and feedback within the context of an organization’s transformation to mature DevOps, DevSecOps, and SRE practices is crucial for several reasons. Definitions provide a foundation to establish metrics and measure the performance and progress for people, processes, and technologies dimensions of holistic digital transformations. The importance, potential benefits, and consequences of having (or not...

Instead of a book with concrete examples of how to do what the title says, it is a book for management types that says "you should go and figure out how to do all these wonderful things." Not worth the paper it's printed on. When I worked for Yahoo, we had a Safari books subscription that every employee had access to. I was able to preview books to figure out if I wanted to spend my own money on them. I would never have purchased this book if I had previewed it.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
