REAL Code Examples from the Repository

Example 1: Basic Speed Test

// Basic speed test initialization
const speedTest = new SpeedTest();

// Start the speed test
speedTest.start();

// Event listener for test completion
speedTest.on('complete', function(result) {
  console.log('Speed Test Result:', result);
});

This example initializes a basic speed test and logs the results to the console. The SpeedTest class is straightforward to use, making it easy to integrate into any project.

Example 2: Stress Test

// Initialize a stress test with a specific duration
const stressTest = new SpeedTest({
  stress: 'High'
});

// Start the stress test
stressTest.start();

// Event listener for test completion
stressTest.on('complete', function(result) {
  console.log('Stress Test Result:', result);
});

This example demonstrates how to run a stress test with a preset duration. The stress parameter can be set to various values like Low, Medium, High, etc., or a specific number of seconds.

Example 3: Automatic Speed Test

// Initialize a speed test to run automatically
const autoTest = new SpeedTest({
  autoRun: true
});

// Start the automatic speed test
autoTest.start();

// Event listener for test completion
autoTest.on('complete', function(result) {
  console.log('Automatic Speed Test Result:', result);
});

This example shows how to run a speed test automatically on page load. The autoRun parameter ensures the test starts immediately without user intervention.
