- Quality Assurance (QA) Processes: Familiarity with QA processes such as peer reviews, code inspections, and unit testing enhances software quality and reduces defects.
Analytical Skills
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:
