Have you tried running tests in parallel on mobile devices?

Yes, running tests in parallel on mobile devices is a common practice to speed up testing and increase coverage.

Typically, tools and frameworks that support parallel execution are used, such as:

• Appium with parallel session configuration
• Firebase Test Lab or AWS Device Farm for cloud-based parallel testing
• Using CI/CD systems with parallel agents

An example using Go and Appium (pseudocode):

func runTestOnDevice(deviceID string, wg *sync.WaitGroup) {
    defer wg.Done()
    // Initialize Appium session for deviceID
    // Run tests
}

func main() {
    devices := []string{"device1", "device2", "device3"}
    var wg sync.WaitGroup
    for _, d := range devices {
        wg.Add(1)
        go runTestOnDevice(d, &wg)
    }
    wg.Wait()
}

This approach allows tests to run simultaneously on multiple devices, reducing overall testing time.
