Explore the Unity interface through a 2D platformer project, identifying scene view, error arch, inspector, project window, and game view, and test colliders, rigidbody, and prefabs.
Discover how Unity game objects act as containers filled with components like transform, sprite renderer, and rigidbody2d to control position, visuals, gravity scale, and Y value for placement.
Explore how prefabs function as master stamps in Unity, updating all instances from one change; distinguish blue linked objects from black unpacked objects and understand how overwrites affect specific levels.
Master the search bars and debug mode to quickly locate assets, filter by type, inspect raw variables, and catch crashes for faster quality assurance.
Discover how the Unity canvas hosts all UI, render modes like screen space overlay, screen space camera, and world space. Learn QA checks for clipping and missing camera references.
Master rect transform basics for UI in Unity, learn how anchors prevent UI from drifting across resolutions, and verify coin counter placement on different aspect ratios.
Master Unity UI by configuring buttons with color states and interactable behavior, adding images and text, and using image types like simple, sliced, and filled, while testing overflow and localization.
Discover how Unity uses a mouse raycast to detect UI clicks, and how raycast target settings decide if objects are clickable or block interactions, including invisible blockers.
Explore the player controller as the movement brain, tune public variables like move speed and jump force, and use debug mode to inspect is grounded and test pc/mobile controls.
Learn how to read Unity console errors and stack traces. Trigger and diagnose failures with Debug.LogError and use console tools like clear, collapse, and errorPause to locate issues quickly.
Identify and fix the three Unity errors—null reference, unassigned reference, and index out of range—by inspecting inspector slots, player controller components, and delivering precise bug reports with screenshots.
Learn to sort Unity errors with the traffic light system—white ready, yellow warning, red crash—by adding debug lines and filtering the console.
Learn how the game manager acts as a switchboard, linking game logic to the UI, tracking score, and triggering the level complete panel while avoiding soft locks.
Learn to test mobile features in Unity with the Device Simulator and install it via Package Manager. Switch to mobile controls and check notch and UI during play.
Configure a qa build by enabling development build, verifying scene order and splash at index 0, and selecting the correct architecture before building in Unity.
Perform a ten-minute smoke test to verify a build launches, runs, and closes without crashes, checks UI and resolution, menu-to-level flow, input responsiveness, focus handling, and exit options.
Discover how to locate and read the Unity player log on Windows to diagnose crashes, copy the log for bug reports, and note that it overwrites on every launch.
Track Unity performance with the in-game stats, keep frame time under 16 ms for 60 fps, watch spikes, and optimize by batching draws to reduce draw calls.
Open the profiler via window analysis to monitor green rendering, blue scripts, and yellow v-sync; inspect spikes and the error archive for 16 milliseconds.
Catch performance spikes by tracing a lag from the LagGenerator script, observe a 281 milliseconds spike in the profiler, and distinguish blue script bottlenecks from green rendering for Unity QA.
Compare client authority and server authority in online games, and learn three critical QA tests—expensive download test, network handover, and the Persian mismatch test—to prevent data desync and bugs.
Explore latency and ping, simulate bad connections, visualize ping, and test lag compensation, jitter, and packet loss using tools like Clumsy or Unity Lag Simulator.
Learn how games persist data through serialization, from simple local saves to cloud saves, covering save formats like player prefs, json, and binary, plus migration and corruption tests.
Enable remote config to adjust game difficulty and events from the server without updates, using a json-based config and testing fallback values, live update scenarios, and a-b testing.
Learn how A/B testing and bucketing shape game decisions, and master QA with sticky buckets, including fresh install re-roll, persistence checks, and cross-platform identity to prevent data confusion.
Explore how rewarded ads work in free-to-play games and the handshake with ad networks, then highlight common bugs and tests like pause issues, callback failures, and the airplane trick.
Assess pc compatibility by testing aspect ratios, inputs, and frame rates across hardware tiers, including minimum specs checks. Verify 4k scaling, alt-tab stress, and ghost input to prevent runtime issues.
Explore how Steam wrappers provide DRM, ownership checks, achievements, and the overlay. Learn QA checks for pause behavior, input focus, offline mode, and cloud conflicts.
Learn to craft precise Jira bug summaries with a feature in brackets, what happened, and condition, then document environment, steps to reproduce, expected results, evidence, and severity/priority.
Explore how detailed test cases and fast checklists support regression and smoke testing for a feature-complete game, using preconditions, precise steps, and design-document based expectations with IDs like PH01.
Define a test plan as a strategic guide that sets scope, entry and exit criteria, assesses risk, and covers smoke, sanity, and regression tests to ensure a reliable release.
Explore how ci-cd pipelines—using TeamCity, Jenkins, or GitHub Actions—automate builds from feature, develop, and main branches and support destructive, integration, and regression testing.
Navigate bug triage in game development by balancing quality and deadlines, and learn to align QA, development, and production roles to decide which bugs ship.

Practice testing a 2D Unity game by logging issues and performing root-cause analysis. Identify UI, animation, physics, and end-zone bugs and learn fixes via data binding, tags, layers, and triggers.
3D FPS game project - in Unity Hub press “Create a project” and find “Learning” tab
To intentionally break the FPS game navigate to the Course folder on Google Drive and find “Scripts” zip file, download it and replace your current “Scripts” file in project folder.
To intentionally break the Fox 2D platformer game, do the same as above, but for 2D Platformer project, and in the end rename the folder to “Scripts”
Become a data-driven Unity tester by embracing the QE engineer mindset, using the engine's own tools to locate broken logic and distinguish bad design from rule violations.
