الآن بما أنكم تفهمون أساسيات k6 واختبار الأداء، فقد حان الوقت لوضع هذه المعرفة موضع التطبيق. هذه المقالة تمرركم من خلال كتابة الاختبارات الحقيقية، ودمجها في خطوط الأنابيب CI/CD، واستخدام أدوات التنميط لتحديد وإصلاح اختناقات الأداء.
هذا الجزء الثاني من a من إثنان جزء سلسلة يعمل التحميل إختبار مع:
إذا لم تقرأ الجزء 1، ابدأ هناك لفهم K6 الأساسيات، التركيب، وأنواع الاختبار قبل الغوص في التنفيذ.
قبل تشغيل إختبارات K6، دعونا نُثبّت قائمة الحد الأدنى للاختبار:
الـ مُستخدِم مشروع:
cd Mostlylucid.MinimalBlog.Demo
dotnet run
أو استخدام DOcker:
docker run -d -p 5000:8080 \
-v $(pwd)/Markdown:/app/Markdown \
--name minimalblog-test \
scottgal/minimalblog:latest
لأغراض الاختبار الدقيق للأداء، يُبنى دائماً في نمط الإصدار:
dotnet run --configuration Release
أنت:
● الطرح ● نمط التنقيط / نمط الإصدار / /
|--------|------------|--------------|
| الـتُبيِّثات تم تمكين المعوقين من الاستفادة الكاملة من عمليات التفتيش المشتركة الكاملة

| تدقيق (تابع) التحقق من السلامة الإضافية على النحو الأمثل في الأماكن الآمنة
| (مُنكر))) 2-10 x أداء خط الأساس الأبطأ
لِمَ يُعطي نمط التنحيط النتائج المُضلِّلة:
Debug.Assert() بيانات التنفيذ، إضافة تأكيدات أن الإنتاج لن يكون لهإلى استخدام نمط الضبط لـ اختبار:
(أ) سير العمل:
# 1. Develop and debug with Debug mode
dotnet run # Debug mode (default)
# 2. Validate functionality works
k6 run --vus 1 --duration 10s smoke-test.js
# 3. Switch to Release for actual performance testing
dotnet run -c Release
# 4. Run full load tests
k6 run load-test.js
(أ) قاعدة التحكم في الإبهامإذا كنت تقيس الأداء، استخدم الإصدار. إذا كنت تصلح الحشرات، استخدم التنقيح.
إنشاء عدّة علامات إلى إختبار مع:
# Create test posts directory
mkdir -p TestMarkdown
# Create sample posts
for i in {1..10}; do
cat > TestMarkdown/test-post-$i.md <<EOF
# Test Post $i
This is test post number $i with some **bold** text and *italic* text.

الآن نحن على استعداد لكتابة اختباراتنا!
دعونا نبدأ بإختبار بسيط للتدخين للتحقق من الوظائف الأساسية:
** smoke-test.js**
import http from 'k6/http';
import { check, sleep } from 'k6';
export const options = {
vus: 1,
duration: '30s',
thresholds: {
http_req_duration: ['p(95)<500'], // 95% of requests should be below 500ms
http_req_failed: ['rate<0.01'], // Less than 1% errors
},
};
const BASE_URL = __ENV.BASE_URL || 'http://localhost:5000';
export default function() {
// Test homepage
let response = http.get(`${BASE_URL}/`);
check(response, {
'homepage status is 200': (r) => r.status === 200,
'homepage has content': (r) => r.body.length > 0,
'homepage response time OK': (r) => r.timings.duration < 500,
});
sleep(1);
// Test a single post
response = http.get(`${BASE_URL}/post/test-post-1`);
check(response, {
'post status is 200': (r) => r.status === 200,
'post has content': (r) => r.body.length > 0,
'post contains title': (r) => r.body.includes('Test Post 1'),
});
sleep(1);
// Test categories page
response = http.get(`${BASE_URL}/categories`);
check(response, {
'categories status is 200': (r) => r.status === 200,

sleep(1);
// Test category filter
