Software Testing Methodologies and Planning Strategies

Categories of System Testing

System Testing is a level of software testing in which the complete integrated system is tested as a whole. It checks whether the software works correctly according to user requirements. System Testing includes different categories that test various features of the software such as performance, security, reliability, and recovery. These categories help in improving the quality and efficiency of the software system.

1. Reliability Testing

Reliability Testing is used to check

Java Shipping Logic and Software Architecture

Shipping Cost Calculation Logic

The following rules define the shipping cost based on weight:

  • Return -1 if the weight is less than 0 or greater than 100 kg.
  • Return 10.00 if the weight is between 0 and 10 kg.
  • Return 20.00 if the weight is between 10.01 and 20 kg.
  • Return 50.00 if the weight is between 20.01 and 50 kg.
  • Return 100.00 if the weight is between 50.01 and 100 kg.

Java Method Implementation

public static double calculateShippingCost(double weight) {
    if (weight < 0 || weight > 100) return

Principles of Effective User Interface Design

Command and Natural Languages

Command languages represent text-based interaction where the user types commands instead of selecting from menus.

Basic Goals of Language Design

  • Precision and compactness
  • Ease of writing and reading
  • Fast learning and simplicity (to reduce errors)
  • Easy retention

Higher-Level Goals

  • Match real-world tasks and be convenient for user tasks
  • Compatible with existing notation
  • Flexible for both novices and experts
  • Expressive and visually appealing
