Test Results

VoltTest provides comprehensive performance metrics and statistics through the TestResult class.

Basic Usage

$result = $test->run();

// Get key metrics
echo "Success Rate: " . $result->getSuccessRate() . "%\n";
echo "Total Requests: " . $result->getTotalRequests() . "\n";

Available Metrics

Basic Metrics

// Test duration
$result->getDuration();           // Returns: "24.000873057s"

// Request counts
$result->getTotalRequests();      // Returns: 5000
$result->getSuccessRequests();    // Returns: 4148
$result->getFailedRequests();     // Returns: 852

// Performance metrics
$result->getSuccessRate();        // Returns: 82.96
$result->getRequestsPerSecond();  // Returns: 208.33

Response Time Statistics

// Time measurements
$result->getMinResponseTime();      // Returns: "7.388011ms"
$result->getMaxResponseTime();      // Returns: "18.179649581s"
$result->getAvgResponseTime();      // Returns: "3.848391356s"
$result->getMedianResponseTime();   // Returns: "8.997304894s"
$result->getP95ResponseTime();      // Returns: "16.74641748s"
$result->getP99ResponseTime();      // Returns: "17.552319263s"

Raw Data Access

// Get all metrics as array
$metrics = $result->getAllMetrics();

// Access raw output
$rawOutput = $result->getRawOutput();

Metrics Format

The TestResult class parses and formats the following output structure:
