Spring Boot. application.properties

Let’s assume we have some paramaters in application.properties that we want to use in our Spring Boot application/tests. With Spring Boot we can do that easily using @Value annotation. Here is an example how to get parameters from application.properties in TestNG tests.

Parameters in application.properties

testData.users.file=test-users.json
site.url=https://www.lenar.io

@Value Spring Boot annotation

@Value("${testData.users.file}")
private String usersFile;

@Value("${site.url}")
private String siteUrl;

TestNG + Spring Boot. application.properties


Using parameters from Spring Boot application.properties in TestNG tests.

package io.lenar.examples.spring;

import java.io.IOException;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.Assert;
import org.testng.annotations.Test;

@SpringBootTest(classes = TestNGWithSpringApplication.class)
public class ApplicationPropertiesExampleIT extends AbstractTestNGSpringContextTests {

    @Value("${testData.users.file}")
    private String usersFile;

    @Value("${site.url}")
    private String siteUrl;

    @Test
    public void testUserFileTest() throws IOException {
        Assert.assertEquals(usersFile, "test-users.json");
    }

    @Test
    public void siteUrlTest() throws IOException {
        Assert.assertEquals(siteUrl, "https://www.lenar.io");
    }

}
