• Collaboration: Working closely with developers to understand software design and identify potential issues.
• Continuous Improvement: Identifying opportunities to improve testing processes and methodologies.
• Regression Testing: Executing regression tests to ensure that new code changes do not introduce new defects or break existing functionality.
• Performance Testing: Conducting performance tests to evaluate the speed, stability, and scalability of software.
• Security Testing: Performing security tests to identify vulnerabilities in software.

Skills Required:

• Strong understanding of software testing principles and methodologies.
• Proficiency in at least one programming language (e.g., Java, Python).
• Experience with test automation frameworks (e.g., Selenium, JUnit, TestNG).
• Familiarity with bug tracking systems (e.g., Jira).

The SDET role has evolved significantly over time, driven by the increasing complexity of software and the growing need for quality assurance. Initially, software testing was primarily a manual process performed by dedicated testers. However, as software development methodologies evolved towards Agile and DevOps, the need for automated testing became more apparent.

Early Days:

• Software testing was primarily a manual process.
• Testers were often separate from developers.
• Testing was typically performed at the end of the development cycle.

The Rise of Automation:

• The introduction of automated testing tools and frameworks.
• The emergence of the SDET role, combining development and testing skills.
• The shift towards continuous testing and integration.

SDET Today:

• SDETs are integral members of development teams.
• They are involved in all stages of the development cycle.
• They are responsible for ensuring the quality of software through automated and manual testing.

Future Trends:

• Increased use of artificial intelligence (AI) and machine learning (ML) in testing.
• Greater emphasis on performance and security testing.
• The rise of cloud-based testing platforms.

Key Milestones:

• The introduction of the Agile methodology.
• The emergence of DevOps practices.
• The development of open-source testing tools and frameworks.

Impact on the Industry:

• Improved software quality.
• Faster release cycles.
• Reduced development costs.
• Increased customer satisfaction.
