Why Testing?

Testing is an essential process in software development that ensures the application meets the specified requirements and functions as intended. It helps identify and resolve issues early, thus improving software quality and user satisfaction. Testing also reduces the risk of failures and mitigates the consequences of potential defects, which can lead to costly system downtime and loss of customer trust.

Causes of software defects

Software defects can arise from various sources, such as requirement misunderstandings, design errors, coding mistakes, data inconsistencies, and hardware failures. Other contributing factors include inadequate testing, communication gaps among team members, and insufficient attention to detail during development.

Tester objectives

The primary objectives of a tester include identifying and reporting defects, verifying that the software meets its requirements, and validating its functionality under various conditions. Testers also strive to ensure that the software is user-friendly, reliable, and secure and that it performs optimally in the target environment.

Testing and debugging

Testing and debugging are complementary processes in software development. Testing involves executing the application under controlled conditions to identify defects and evaluate its quality. Debugging, on the other hand, is the process of identifying the root causes of defects and fixing them. While testing uncovers issues, debugging helps resolve them to improve software quality.

Principles of testing

Some fundamental principles of testing include the following:

  1. Testing shows the presence of defects, not their absence.
  2. Exhaustive testing is impossible due to the infinite number of possible inputs and conditions.
  3. Early testing is essential to identify and resolve issues before they become more complex and costly.
  4. Defect clustering refers to the phenomenon where a small number of modules contain most of the defects.
  5. The pesticide paradox states that repeatedly using the same test cases will eventually become less effective as the software evolves.
  6. Testing should be context-driven, considering project requirements, risks, and resources.

Test activities

Test activities typically involve planning, designing, executing, and evaluating tests and reporting and tracking defects. These activities can be carried out at various stages of software development, including requirements analysis, design, implementation, and maintenance.

Retesting

Retesting is executing previously failed test cases after defects have been fixed to ensure that the issues have been resolved and no new problems have been introduced.

Resource triangle

The resource triangle represents the relationship between time, cost, and scope in software testing. Balancing these three factors is critical to achieving optimal testing coverage and results within project constraints.

Completion criteria

Completion criteria are predefined metrics and conditions that determine when testing is complete. These criteria can include factors such as test coverage, the number of defects detected and fixed, and the acceptable level of residual risk.

Static and dynamic testing

Static testing involves analyzing software artefacts, such as requirements, design documents, and source code, without executing the application. Techniques include reviews, inspections, and static analysis tools. On the other hand, dynamic testing involves executing the software to observe its behaviour and evaluate its quality. Techniques include functional, non-functional, and structural testing.

Testing independencies

Independent testing is having a separate team or individual, not involved in the software development process, perform testing. This approach helps ensure objectivity and reduces the risk of overlooking defects due to familiarity with the code or design.

Code of Ethics

The Code of Ethics for software testers emphasizes professional conduct, competence, confidentiality, and the responsibility to act in the best interest of stakeholders. Adhering to this code promotes trust, credibility, and integrity within the software testing profession.
