JUnit5 execution condition that checks whether a connection to public Internet is available.

First, you add this to your pom.xml:

<dependency>
  <groupId>com.yegor256</groupId>
  <artifactId>jping</artifactId>
  <version>0.0.3</version>
  <scope>test</scope>
</dependency>

Then, you use it like this:

import com.yegor256.WeAreOnline;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

@ExtendWith(WeAreOnline.class)
final class MyTest {
  @Test
  void canDownloadViaHttp() throws Exception {
    new URL("https://www.google.com").openStream();
  }
}

Or if need to override default settings:

import com.yegor256.OnlineMeans;
import com.yegor256.WeAreOnline;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;

@ExtendWith(WeAreOnline.class)
final class MyTest {
    @Test
    @OnlineMeans(url = "https://www.amazon.com", connectTimeout = 500, readTimeout = 1500)
    void canDownloadViaHttp() throws Exception {
        new URL("https://www.amazon.com").openStream();
    }
}

We don't want this unit test to be executed when no Internet connection is available. The WeAreOnline execution condition will prevent JUnit5 from executing the test when you are offline.
