Injecting a URI

It is also possible to directly inject the URL into the test which can make it easy to use a different client. This is done via the @TestHTTPResource annotation.

  1. Let’s write a simple test that shows this off to load some static resources.

  2. Create a new file names test.html file in src/main/resources/META-INF/resources/.

  3. Paste the folloing HTML code to the file:

    <html>
<head>
  <title>Testing with Quarkus</title>
</head>
<body>
  <p>... it's fun and entertaining!</p>
</body>
</html>

  4. Our test will verify that the <title> tags contain the right content.

  5. Next, create a new test under src/test/java in the org.acme.people package called StaticContentTest.java. Replace this code to the file:

    package org.acme.people;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;
import java.nio.charset.StandardCharsets;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

import io.quarkus.test.common.http.TestHTTPResource;
import io.quarkus.test.junit.QuarkusTest;

@QuarkusTest
public class StaticContentTest {

    @TestHTTPResource("test.html") // (1)
    URL url;

    @Test
    public void testIndexHtml() throws Exception {
        try (InputStream in = url.openStream()) {
            String contents = readStream(in);
            Assertions.assertTrue(contents.contains("<title>Testing with Quarkus</title>"));
        }
    }

    private static String readStream(InputStream in) throws IOException {
        byte[] data = new byte[1024];
        int r;
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        while ((r = in.read(data)) > 0) {
            out.write(data, 0, r);
        }
        return new String(out.toByteArray(), StandardCharsets.UTF_8);
    }
}
    1 The @TestHTTPResource annotation allows you to directly inject the URL of the Quarkus instance, the value of the annotation will be the path component of the URL. For now @TestHTTPResource allows you to inject URI, URL and String representations of the URL.

  6. The test results will be updated automatically in the terminal:

    All 3 tests are passing (0 skipped), 1 test was run in 451ms. Tests completed at 01:34:45 due to changes to StaticContentTest.class.
