What is the difference between a tester and a quality assurance specialist?

The process of creating and documenting test scenarios, test data, and verification conditions based on requirements and specifications. The goal is to test the product's functionality, performance, usability, and other aspects as thoroughly and efficiently as possible. Key tasks include defining what to test, how to test, what data to use, and what success criteria to apply.

Main test design techniques include:

• Specification-based techniques (Black-Box Testing):

  • Equivalence Partitioning
  • Boundary Value Analysis
  • Decision Table Testing
  • State Transition Testing
  • Pairwise Testing
  • Use Case Testing

• Structure-based techniques (White-Box Testing):

  • Statement Coverage
  • Decision/Branch Coverage
  • Condition Coverage
  • Path Coverage

• Experience-based techniques:

  • Exploratory Testing
  • Error Guessing
  • Ad-hoc Testing

The test design process typically involves:

1. Requirements and specifications analysis.
2. Test areas identification.
3. Selection of suitable test design techniques.
4. Development of test cases.
5. Selection of test data.
6. Creation of preconditions and postconditions.
7. Documentation of test artifacts (Test Plan, Test Cases, Test Data).
