🧪 Restful Booker - JMeter Performance & Stress Testing

This project demonstrates performance and stress testing on the Restful Booker API using Apache JMeter. It includes simulation of real-world traffic: login, create a booking, and search for a booking, along with timed execution and report generation.

---

✅ What Has Been Done

• Designed a JMeter test plan (booking.jmx) that simulates:

  • User login
  • Booking creation with random data
  • Booking search using extracted booking ID

• Applied a Gaussian Random Timer (Deviation: 2000ms, Constant Delay: 500ms) for realistic traffic simulation

• Performed Load Testing in 3 steps:

  • Step 1: 5 minutes
  • Step 2: 10 minutes
  • Step 3: 15 minutes

• Performed Stress Testing by gradually increasing users until bottlenecks were observed

• Collected test results in .jtl format and generated:

  • 📊 HTML reports
  • 📈 Excel summary: booking-api-test-report.xlsx

---

🔧 Prerequisites

• JMeter 5.5 or later
• Java 8 or higher
• Git (for cloning the repo)

---

🚀 How to Run the Test

# Step 1: Clone the repo
git clone https://github.com/your-username/RestfulBooker_Jmeter_Testing.git
cd RestfulBooker_Jmeter_Testing

# Step 2: Open booking.jmx in JMeter

# Step 3: Run the test (GUI or CLI mode)
# For GUI: Open booking.jmx in JMeter and press Start
# For CLI: jmeter -n -t booking.jmx -l booking.jtl

# Step 4: Generate HTML report
jmeter -g booking.jtl -o Reports/
