• The Business Impact of Performance: Understand how performance directly influences revenue and customer satisfaction.
• The Economics of Performance Testing: Learn how to justify and implement cost-effective performance testing strategies.
• Key Performance Testing Terminology: Grasp essential concepts like:
  • Response Time: Measure how long it takes for a server to respond to a request.
  • Think Time: Simulate user pauses between actions.
  • Pacing Time: Control the rate at which virtual users execute tasks.
  • Concurrency: Simulate multiple users accessing the system simultaneously.
  • Vuser: Virtual User - the simulated user performing actions.
  • Latency: Delay in data transfer.
• Architectural Concepts: Explore various application architectures and their impact on performance.
• Resource Utilization: Learn how to monitor and optimize server resource usage (CPU, Memory, Network).
• Types of Performance Tests: Understand different testing types, including load, stress, endurance, and spike testing.
• Performance Test Life Cycle: Follow a structured approach to performance testing:
  • Stages: Planning, Design, Execution, Analysis, Reporting.
  • Activities: Requirements gathering, test case creation, test environment setup, test execution, result analysis.
  • Best Practices: Implement proven strategies for effective performance testing.

HTTP/HTML Protocol Deep Dive

Gain a solid understanding of how web applications function:

• HTTP Request & Response: Learn the core mechanics of client-server communication.
• HTTP Headers: Understand the role of headers in conveying information.
• Response Codes: Interpret HTTP status codes to diagnose issues.
• HTTP Methods: Master common methods like GET, POST, PUT, and DELETE.
• URL Encoding: Understand how URLs are structured and encoded.
• Using Developer Tools: Utilize browser developer tools to analyze HTTP traffic.

Performance Testing Metrics & Laws

• Essential Statistics: Calculate and interpret key performance metrics:
  • Average: The mean value of a set of data.
  • Standard Deviation: A measure of data dispersion.
  • Percentile: The value below which a given percentage of data falls.
• Basic Performance Laws: Apply fundamental principles to predict and optimize performance.

Hands-on Jmeter Training

Develop practical skills with Apache JMeter, the industry-leading open-source performance testing tool:

  • TestPlan: The core of your test plan.
  • ThreadGroup: Simulate user groups.
  • Listeners: Collect and display test results.
  • Samplers: Send requests to the server.
  • Timers: Introduce delays and pacing.
  • Pre-processors: Prepare data before requests.
  • Post-processors: Process responses after requests.
  • DebugSampler: Step-by-step script debugging.
  • HTTPs Test Script Recorder: Record HTTP(S) requests.
• Regular Expressions: Extract and manipulate text using regular expressions.
• Groovy Scripting: Extend JMeter functionality with Groovy scripts.
• Script Recording: Learn how to record browser activity for automated testing.
  • Browser Proxy Settings: Configure browser proxy settings.
  • Security Certificates: Handle security certificates.
