Browser Synthetic Tests
1. Introduction
Browser Synthetic Tests are a type of monitoring technique that simulates user interactions with web applications to measure performance, availability, and functionality. These tests help identify issues before they affect real users.
2. Key Concepts
- **Synthetic Monitoring**: A method of testing that simulates user behavior to monitor application performance.
- **User Journeys**: Predefined sequences of interactions that mimic the paths users take through a website.
- **Performance Metrics**: Key performance indicators such as page load time, response time, and error rates.
- **Geographic Testing**: Running tests from different locations to assess performance based on user geography.

3.1 Define User Journey
Identify the critical user paths within your application that need to be monitored.
3.2 Set Up Monitoring Tool
Select and configure a synthetic monitoring tool (e.g., Pingdom, New Relic) to automate the testing process.
3.3 Configure Test Parameters
Specify parameters such as geographic locations, frequency of tests, and performance thresholds.
3.4 Run the Test
Execute the configured tests to simulate user interactions and gather performance data.
3.5 Analyze Results
Review the collected data to identify any potential issues or performance bottlenecks.
3.6 Optimize Performance
Based on the analysis, implement optimizations to enhance the user experience.
4. Best Practices
- Regularly update user journeys to reflect changes in user behavior.
- Use multiple geographic locations to gain insights into performance variability.
- Integrate synthetic tests with alerting systems for immediate notifications of issues.
- Combine synthetic monitoring with real user monitoring for comprehensive insights.
5. FAQ
What is the difference between synthetic monitoring and real user monitoring?
Synthetic monitoring simulates user interactions to test performance, while real user monitoring (RUM) collects data from actual users to analyze performance in real-time.
How often should I run synthetic tests?
It’s recommended to run synthetic tests regularly—at least once an hour, depending on the criticality of the application.
Can synthetic tests identify all performance issues?
No, synthetic tests cannot capture every issue, especially those related to real user behavior. It’s best used in conjunction with other monitoring methods.
