Explain STLC with an example.

 Software Testing Life Cycle (STLC) defines a structured approach to testing in the SDLC process. It includes:

  1. Requirement Analysis – Understanding client requirements.
  2. Test Planning – Defining test strategies and schedules.
  3. Test Design – Creating test cases and scripts.
  4. Test Execution – Running tests manually or using automation.
  5. Defect Lifecycle – Reporting and tracking bugs until resolved.
  6. Test Closure – Evaluating testing outcomes and ensuring quality.

For example, in an e-commerce application, testers validate features like product search, checkout, and payments through these structured phases.

How do you log a bug?

 A bug (or defect) is an issue identified during testing that affects functionality. It is logged using a defect tracking tool (e.g., Jira, Bugzilla) with the following details: Defect ID – Unique identifier for tracking. Summary – Brief description of the issue. Description – Steps to reproduce the bug. Severity – Impact level (High, Medium, Low). Priority – Fixing urgency (Critical, High, Medium, Low). Environment – Where the bug was found (Dev, Test, Prod). Assigned To – Developer responsible for fixing. Status – Open, In Progress, Resolved, Closed. Attachments – Screenshots/logs for reference.

What is CI, CD and CT?

 In software development, CI (Continuous Integration), CD (Continuous Delivery/Deployment), and CT (Continuous Testing) are key DevOps practices that streamline the software development lifecycle by enabling automation, rapid feedback, and continuous deployment of high-quality code. Continuous Integration (CI): Developers frequently merge code changes into a shared repository, triggering automated builds and tests to detect issues early, ensuring stability and consistency. Continuous Delivery/Deployment (CD): Automates the release process; in Continuous Delivery , deployments require manual approval, whereas in Continuous Deployment , releases occur automatically without manual intervention. Continuous Testing (CT): Involves running automated tests throughout development, providing real-time feedback on code quality and reducing the risk of defects reaching production.
