Khatar AI Chatbot – AI-Powered Mobile Application

Role: Mobile QA Engineer / AI Chatbot Tester Project Type: AI Chatbot Mobile App Testing Focus: Conversational AI Testing, NLP Validation, Intent Testing, Mobile Functional Testing, Regression Testing

Khatar AI Chatbot is an AI-powered mobile application designed to help users interact through natural conversations. The app required detailed QA coverage to ensure that chatbot responses were accurate, relevant, context-aware, and useful across different user inputs and conversation scenarios.

Since chatbot applications depend heavily on intent recognition, response quality, fallback handling, and multi-turn conversation flow, the testing approach focused on both traditional mobile app testing and AI-specific validation.

The client needed complete testing coverage for the chatbot’s core conversation experience. The main goal was to verify that the chatbot could understand different user intents, respond correctly, handle unclear inputs, maintain context during longer conversations, and recover smoothly when it did not understand a user request.

The client also needed regression testing after model updates to ensure that improvements in one area did not break existing chatbot behavior.

I worked as a Mobile QA Engineer and AI Chatbot Tester, responsible for validating the chatbot experience from the user side. My work included testing conversational flows, checking intent mapping, validating response accuracy, reviewing tone and relevance, and reporting issues related to broken conversations or incorrect chatbot behavior.

I also collaborated with developers and AI team members to help improve training data, refine chatbot responses, and strengthen the overall quality of the conversation experience.

I conducted end-to-end testing of the AI chatbot mobile application, covering both mobile app functionality and AI conversation behavior. I tested how the chatbot responded to multiple user intents, unclear questions, repeated prompts, incomplete inputs, and edge-case scenarios.

I designed and executed test scenarios for common user flows, alternative phrasing, ambiguous inputs, incorrect spelling, short commands, long questions, and multi-turn conversations. This helped evaluate how well the chatbot understood user intent and maintained context across the conversation.

I validated chatbot responses based on relevance, correctness, tone, clarity, and contextual continuity. I also checked fallback responses to ensure that the chatbot handled unknown or unsupported queries in a user-friendly way instead of breaking the conversation.

During testing, I identified and reported issues related to incorrect intent mapping, irrelevant answers, repeated fallback responses, broken conversation flow, missing context, and inconsistent chatbot behavior after model updates. I documented defects clearly with input examples, actual responses, expected behavior, and conversation steps so the team could reproduce and improve them.
