I've deeply studied SDLC. This course included classes about planning, scheduling, estimating, monitoring, reporting, control and completion of test activities and studies concerning process of recognizing, recording, classifying, investigating, resolving and disposing of defects. Also I`ve learned Scrum and Kanban workflows and something about Project Management. On this couse I`ve created Test Cases, wrote Defect reports and used Test Techniques.
I've grasp the basic theoretical questions such as: Software Development Lifecycle, Fundamentals of testing, Requirements, Test types and test levels.
