Apache JMeter™ is a powerful open-source load testing tool used to analyze and measure the performance of various software applications, with a primary focus on web applications. Originally designed for web application testing, it has expanded to cover a wide range of testing functions.
Key Features:
- Versatile Testing: Supports testing of web applications (HTTP, HTTPS), web services (SOAP/REST), databases (JDBC), LDAP, JMS, mail protocols (SMTP(S), POP3(S), IMAP(S)), and more.
- Test IDE: Provides a full-featured IDE for rapid test plan creation, recording, building, and debugging.
- Command-Line Mode: Offers a CLI mode for load testing from any Java-compatible OS.
- Dynamic HTML Reporting: Generates ready-to-present dynamic HTML reports.
- Data Extraction: Simplifies data correlation with the ability to extract data from HTML, JSON, XML, and other formats.
- Extensible Core: Features pluggable samplers, scriptable samplers (Groovy, BeanShell), pluggable timers, and visualization plugins.
Use Cases:
- Load Testing: Simulates heavy load on servers, networks, or objects to test strength and analyze performance under different load types.
- Performance Testing: Measures the performance of static and dynamic resources and web applications.
- Regression Testing: Ensures that new code changes do not adversely affect existing functionality.
- API Testing: Tests the performance and reliability of APIs.
- Database Testing: Evaluates database performance under load.
JMeter is not a browser; it operates at the protocol level, simulating multiple browsers to test server performance. It does not execute JavaScript or render HTML pages like a browser.
