Software Testing Curve

1. Can you explain the PDCA cycle and where testing fits in? Software testing is an important part of the software development process. In normal software development there are four important steps, also referred to, in short, as the PDCA (Plan, Do, Check, Act) cycle. Let's review the four steps in detail. Plan:  Define the goal and the plan for achieving that goal. Do/Execute:  Depending on the plan strategy decided during the plan stage we do execution accordingly in this phase. Check:  Check/Test to ensure that we are moving according to plan and are getting the desired results. Act:  During the check cycle, if any issues are there, then we take appropriate action accordingly and revise our plan again. So developers and other stakeholders of the project do the "planning and building," while testers do the check part of the cycle. Therefore, software testing is done in check part of the PDCA cyle. 2. What is the difference between white box, blac

As a software developer, you certainly have a high-level picture of how web apps work and what kinds of technologies are involved: the browser, HTTP, HTML, web server, request handlers, and so on. In this article, we will take a deeper look at the sequence of events that take place when you visit a URL. 1. You enter a URL into the browser It all starts here: 2. The browser looks up the IP address for the domain name   The first step in the navigation is to figure out the IP address for the visited domain. The DNS lookup proceeds as follows: Browser cache –  The browser caches DNS records for some time. Interestingly, the OS does not tell the browser the time-to-live for each DNS record, and so the browser caches them for a fixed duration (varies between browsers, 2 – 30 minutes). OS cache  – If the browser cache does not contain the desired record, the browser makes a system call (gethostbyname in Windows). The OS has its own cache. Router cache

Clickjacking Clickjacking  ( User Interface redress attack ,  UI redress attack ,  UI redressing ) is a  malicious technique  of tricking a  Web   user  into clicking on something different from what the user perceives they are clicking on, thus potentially revealing  confidential  information or taking control of their computer while clicking on seemingly innocuous  web pages . It is a  browser security  issue that is a  vulnerability  across a variety of  browsers  and  platforms . A clickjack takes the form of embedded  code  or a script that can execute without the user's knowledge, such as clicking on a  button  that appears to perform another function. [5]  The term "clickjacking" was coined by Jeremiah Grossman and Robert Hansen in 2008. [ citation needed ]  Clickjacking can be understood as an instance of the  confused deputy problem .
