11. Enterprise Java Design Patterns for Test Automation

Enums for Type-Safe Automation

Avoid passing error-prone raw strings like "chrome" or "prod".

public enum BrowserType {
    CHROMIUM("chromium"),
    FIREFOX("firefox"),
    WEBKIT("webkit");
private final String value;
    BrowserType(String value) { this.value = value; }
    public String getValue() { return value; }
}
public enum Environment {
    DEV("https://dev.targetqa.com"),
    STAGING("https://staging.targetqa.com"),
    PROD("https://targetqa.com");
private final String url;
    Environment(String url) { this.url = url; }
    public String getUrl() { return url; }
}
