Fundamentals of Software Testing

Imagine you buy a new remote-control car. Before playing with it, you check if it moves forward, turns left or right, and stops when you press stop. If something doesn’t work, you fix it before giving it to someone. Software Testing is exactly this, but instead of a toy, we check software (apps, websites, programs). It is the process of checking software to find errors (bugs) and to make sure it works correctly according to user requirements.

Objectives of Software Testing

• To find bugs: Like finding holes in a bucket before filling it with water.
• To check correctness: Making sure the output is right, not wrong.
• To improve quality: Better software leads to happy users.
• To ensure reliability: Software should not crash

White-Collar Crime: Definition and Context

White-collar crime cannot be understood only by looking at the illegal act. It refers to crimes committed from positions of social and economic power, usually within organizational or corporate contexts. What defines these crimes is not only illegality, but the status of the offender, their access to power, and the abuse of trust and authority involved. According to Sutherland, white-collar crime differs from street crime because it is embedded in legitimate institutions.

Survival-Based Crime vs Elite Crime

The main difference between survival-based crime and elite crime lies in motivation. Survival-based crime is motivated by necessity or subsistence, while elite crime is motivated by profit, advantage,

Why Barcelona Changed Its Image

Why has Barcelona changed its image in recent years? In recent years, Barcelona's branding has slowly changed, mainly because the old tourist image started to cause problems.

From Tourism to a More Realistic City Image

Unit 1: Foundations of Political Theory

Political theory studies the ideas, values, and principles that influence human action in society. The twentieth century was marked by scientific and technological development and by powerful ideologies such as totalitarianism, nationalism, and racism.

Ethics is defined as the systematic study of human relations and the values that guide our decisions. To understand politics, we must first understand moral ideals.

The Platonic ideal claims that there are universal and objective moral truths. Modern thought questions this idea by emphasizing historical change and moral pluralism.

Social Contract Theorists

• Thomas Hobbes: Describes the state of nature as a condition of permanent insecurity and potential conflict.

Define Global Warming and Its Indicators

Definition:

Experiment No. 1: Normal Consistency of Cement

Objective

To determine the normal consistency of a given sample of cement.

Apparatus

• Vicat apparatus (conforming to IS: 5513-1976)
• Balance
• Gauging trowel
• Stopwatch

Theory

To determine the initial setting time, final setting time, soundness, and strength of cement, a parameter known as standard consistency must be used. The standard consistency of a cement paste is defined as the consistency that permits a Vicat plunger (10 mm diameter and 50 mm length) to penetrate to a depth of 33–35 mm from the top of the mould.

Procedure

1. The standard consistency of a cement paste is defined as the consistency that permits the Vicat plunger to penetrate to a point 5 to 7 mm from the bottom of the Vicat mould.
