Analytical Skills

What skills are required to be a software tester

Analytical skills are essential for software testers. They involve the ability to analyze and interpret software requirements and specifications, identify and evaluate software defects, and assess and prioritize risks.

To effectively analyze software requirements, testers must understand the business needs and objectives that the software is intended to meet. They must also be able to identify and interpret any ambiguities or inconsistencies in the requirements.

Identifying and Evaluating Software Defects

Software testers use a variety of methods to identify and evaluate software defects, including:

  • Static analysis: This involves examining the source code of a software application to identify potential defects.
  • Code reviews: This involves manually reviewing the source code of a software application to identify defects.
  • Testing: This involves executing a software application to identify defects.

Once defects have been identified, testers must evaluate their severity and impact. This involves considering the potential consequences of the defect, as well as the likelihood of the defect occurring.

Risk Assessment and Prioritization

Risk assessment is an important part of software testing. It involves identifying and evaluating the risks associated with a software application. Testers use a variety of risk assessment techniques, including:

  • Failure modes and effects analysis (FMEA): This technique involves identifying the potential failure modes of a software application and evaluating their impact and likelihood.
  • Fault tree analysis (FTA): This technique involves constructing a graphical representation of the potential causes of a software failure.

Once risks have been identified and evaluated, testers must prioritize them. This involves considering the severity of the risks, the likelihood of the risks occurring, and the cost of mitigating the risks.

Understanding Software Architecture and Design Principles

Understanding software architecture and design principles is essential for analytical testing. This involves understanding how a software application is structured and how its components interact with each other.

Testers must also understand the design principles that were used to develop the software application. This will help them to identify potential defects and to develop effective test cases.
