Question

Configuration Class

public class Configuration {

    protected SSLConfig config = null;
    private static final Logger LOG = LoggerFactory.getLogger(Configuration.class);

    @SuppressWarnings("deprecation")
    @BeforeClass
    public void setKeystore()

    {
        KeyStore keyStore = null;

        KeyStore trustStore = null;
        try {
            String certPassword = System.getProperty("certPassword");
            String certPath = System.getProperty("certPath");

            String trustStorePassword = System.getProperty("trustStorePassword");
            String trustStorePath = System.getProperty("trustStorePath");
            Validate.notNull(certPath, "Path to Certificate on the file system cannot be null");
            Validate.notEmpty(certPassword, "Password cannot be empty");
            Validate.notNull(trustStorePath, "Path to trustStore on the file system cannot be null");
            Validate.notEmpty(trustStorePassword, "TrustStore Password cannot be empty");

            keyStore = KeyStore.getInstance("JKS");
            keyStore.load(new FileInputStream(certPath), certPassword.toCharArray());
            trustStore = KeyStore.getInstance("JKS");
            trustStore.load(new FileInputStream(trustStorePath), trustStorePassword.toCharArray());

            if (keyStore != null) {

                org.apache.http.conn.ssl.SSLSocketFactory clientAuthFactory = new org.apache.http.conn.ssl.SSLSocketFactory(
                        keyStore, certPassword, trustStore);
                config = new SSLConfig().with().sslSocketFactory(clientAuthFactory).and().allowAllHostnames();

            }
            EnvironmentConstants.getEnvironment();

        } catch (Exception e) {
            LOG.error("Error while loading keystore");
            e.printStackTrace();
        }
    }

    @BeforeTest
    public Properties loadproperties() {

        InputStream input = getClass().getClassLoader().getResourceAsStream("errorMessages.properties");
        Properties properties = new Properties();
        try {
            properties.load(input);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return properties;
    }

}
