Properties Files for Config

Example

src/test/resources/config.properties

base.url=https://qa.shopease.example.com
browser=chrome
headless=false
explicit.wait.seconds=10

Example

java.util.Properties reads the file; a system property (-Dbrowser=firefox) can override a value. Here the file content comes from a string:

import java.io.StringReader;
import java.util.Properties;

public class Main {
    public static void main(String[] args) throws Exception {
        String file = """
            base.url=https://qa.shopease.example.com
            browser=chrome
            explicit.wait.seconds=10
            """;
        Properties config = new Properties();
        config.load(new StringReader(file));

        System.setProperty("browser", "firefox");      // as if run with mvn test -Dbrowser=firefox
        String browser = System.getProperty("browser", config.getProperty("browser"));
        int wait = Integer.parseInt(config.getProperty("explicit.wait.seconds"));
        String retries = config.getProperty("retry.count", "0");   // default when missing

        System.out.println("URL: " + config.getProperty("base.url"));
        System.out.println("Browser: " + browser + " (file says " + config.getProperty("browser") + ")");
        System.out.println("Wait: " + wait + "s, retries: " + retries);
    }
}

Output

URL: https://qa.shopease.example.com
Browser: firefox (file says chrome)
Wait: 10s, retries: 0
