AI QA Q&A

---

🔹 1. AI-Powered Test Case Generation / AI बाट Test Case कसरी Generate हुन्छ?

AI-powered test case generation भनेको यस्तो प्रक्रिया हो जहाँ Artificial Intelligence ले आफ्नो trained model प्रयोग गरेर test cases स्वतः लेख्छ — code, user story, वा requirement को आधारमा।

🔍 Traditional QA मा tester ले test case manually लेख्थ्यो, तर अब AI ले त्यो काम smart तरिकाले गर्न सक्छ।

---

✅ कसरी काम गर्छ? (How It Works)

🧠 Step-by-Step AI Test Generation Process:

1. Input Analysis:
   • Source code, BDD feature file, या requirement document लाई AI ले पढ़्छ।
2. NLP (Natural Language Processing):
   • Text को meaning निकालेर AI ले test case को structure बनाउँछ।
3. Prediction Model:
   • Trained ML models ले कुन step test case मा आउनुपर्ने हो भनेर अनुमान गर्छ।
4. Test Case Output:
   • Final output structured test cases in Gherkin, Java, JSON, or Excel format.

---

🧪 Example Scenario:

🔸 Input:

“As a user, I want to log in using email and password so that I can access the dashboard.”

🔹 AI Generated Test Case (Gherkin Style):

gherkin

CopyEdit

Scenario: User logs in with valid credentials

  Given the user is on the login page

  When the user enters a valid email and password

  And clicks the login button

  Then the dashboard should be displayed

✅ Tester ले यो test case बाट automation script तयार गर्न सक्छ, or AI ले त्यसलाई code मा पनि convert गर्न सक्छ।

---

📌 Benefits of AI Test Case Generation

Benefit	Explanation
⏱️ Faster Test Design	Manual effort बचत, test plan तुरुन्त तयार
🧠 Consistent Coverage	Human error घटाउँछ, logic gaps detect गर्छ
📊 Data-Driven Testing	AI ले past bugs र usage pattern बाट test prioritize गर्छ
🔄 Requirement Traceability	Each test case को requirement source maintain हुन्छ
⚙️ CI/CD Friendly	Frequent builds मा quickly new tests generate हुन्छन्

---

🤖 Copilot + Healenium + TestGen Tools मिलाएर के हुन्छ?

You can:

• Copilot बाट test script लेख्न,
• Healenium बाट flaky locator handle गर्न,
• AI tools बाट smart test case generation integrate गर्न।

👉 यो combination ले Next-Level QA Automation Framework बनाउँछ।

🔹 2. Visual Testing using AI / AI प्रयोग गरेर Visual Testing

Visual Testing भनेको UI को visual elements (text, layout, spacing, colors, buttons) को सही रूपमा rendering भएको छ कि छैन भनेर test गर्ने प्रक्रिया हो।

AI-based Visual Testing ले screenshot comparison मात्र होइन — intelligent pixel, DOM, र layout level मा smart comparison गर्छ।

🔍 Traditional testing ले केवल element present छ कि छैन हेर्छ। Visual AI Testing ले UI सही देखिन्छ कि छैन भन्ने test गर्छ।

---

🧠 Why Traditional Visual Testing Fails

Problem	Example
✅ Locator ठीक छ तर UI बिग्रेको	Button UI मा overlap, cutoff, या alignment issue
✅ Text change भयो	Minor content change ले assertion fail गर्दैन, तर visually खराब देखिन्छ
❌ Responsive design बिग्रिएको	Mobile view मा UI misalign भए पनि test pass हुन सक्छ

---

🤖 AI Visual Testing कसरी काम गर्छ?

🔸 Step-by-Step Process:

1. Baseline Screenshot Capture
   → First run मा app को screenshot capture हुन्छ।
2. New Screenshot Capture During Test
   → हरेक test execution मा नया screenshot लिन्छ।
3. AI-Powered Comparison
   → AI ले pixel, layout, font-size, spacing, alignment, even visual noise सम्म detect गर्छ।
4. Smart Highlighting
   → Minor expected changes ignore गरेर meaningful diffs मात्र देखाउँछ।
5. Report Generation
   → Visual diff को screenshot र issue summary generate हुन्छ।

---

java

CopyEdit

Eyes eyes = new Eyes();

eyes.open(driver, “MyApp”, “Login Test”, new RectangleSize(800, 600));

eyes.checkWindow(“Login Page Visual Check”);

eyes.close();

✅ यो code ले UI को snapshot लिएर baseline सँग compare गर्छ।

---

🔹 3. Predictive Defect Analysis with AI

AI प्रयोग गरेर कुन भागमा bug आउन सक्छ भन्ने कुरा advance मा थाहा पाउने प्रक्रिया।

---

🧠 What is Predictive Defect Analysis?

Predictive defect analysis भनेको testing सुरु गर्नु अघि नै AI ले अनुमान गर्छ कि कुन module, file, वा feature मा bug आउन सक्छ।
यो अनुमान past defect data, code complexity, commit frequency, र test coverage जस्ता चीजहरूमा based हुन्छ।

🔍 Imagine doing smart testing only where it matters most.

---

⚙️ AI कसरी defect अनुमान गर्छ?

🔸 Step-by-Step Process:

1. Historical Data Collection
   → Jira, GitHub, या Bugzilla बाट past defects को log, commit history, test failure pattern ल्याइन्छ।
2. Feature Extraction
   → कुन module कति change भएको छ, complexity के छ, coverage कति छ आदि कुरा analyze हुन्छ।
3. ML Model Training
   → Trained models (Random Forest, Decision Tree, or Neural Networks) use गरेर “bug-prone areas” predict गर्छ।
4. Prediction Layer
   → Model ले यस्तो भनिदिन्छ:
   👉 “Module A मा bug आउनको chance 82% छ”
   👉 “Component X frequently fails under stress test”
5. Test Priority Assignment
   → QA टीमले यस्तो module लाई high priority test set मा राख्छ।

🔹 5. AI in CI/CD Pipelines (Test Selection & Optimization)

CI/CD pipeline मा AI प्रयोग गरेर smart test चलाउने तरिका

CI/CD pipeline मा सबै test हरु हरेक पटक run गर्नु time-consuming र inefficient हुन्छ। AI ले यो समस्या solve गरेर smart test selection र test optimization गर्न मद्दत गर्छ।

🔍 AI ले decide गर्छ कुन-कुन test चलाउने based on recent code changes, history, र risk factor.

---

🧠 Why It Matters?

• ⌛ Time बचत: 1,000+ test case हरू मध्ये केवल 50–100 वटा जरूरी test मात्र run हुन्छ।
• 🚀 Faster Deployment: Build pipeline तुरुन्त pass हुन्छ।
• ⚠️ Risk Coverage: Important test miss नहुने AI logic प्रयोग हुन्छ।

---

⚙️ How AI Works in CI/CD Testing

🔸 Step-by-Step Flow:

1. Code Change Detection
   → GitHub, GitLab जस्ता system बाट recent commits ट्र्याक हुन्छ।
2. Impact Analysis
   → कुन component impact भयो, त्यसमा related test case हरू खोजिन्छ।
3. Historical Defect Analysis
   → Past failure pattern हेरेर कुन test important हो भनेर AI decide गर्छ।
4. Smart Test Selection
   → केवल उनै test case run हुन्छन् जुन relevant छन् — बाकि skip हुन्छ।
5. Confidence Scoring
   → Run हुने हरेक test लाई confidence score assign हुन्छ: Low, Medium, High
