Mobile Testing on Cloud

// Android

caps.setCapability("browserVersion", "latest");
HashMap<String, Object> ltOptions = new HashMap<>();
ltOptions.put("platformName", "android");

// iOS — IMPORTANT: use Safari, not Chrome
DesiredCapabilities iosCaps = new DesiredCapabilities();
iosCaps.setCapability("browserName", "Safari");
iosCaps.setCapability("browserVersion", "latest");
HashMap<String, Object> iosOptions = new HashMap<>();
iosOptions.put("platformName", "ios");
iosOptions.put("deviceName", "iPhone 16");

Test Status Reporting

// Java
((JavascriptExecutor) driver).executeScript("lambda-status=" + (passed ? "passed" : "failed"));

// With remark
((JavascriptExecutor) driver).executeScript(
    "lambda-action: {\"action\": \"setTestStatus\", \"arguments\": {\"status\": \""
    + status + "\", \"remark\": \"" + remark + "\"}}"
);
