How to replace @Rule annotation in JUnit 5 on TextReport and BrowserWebDriverContainer?

Question

I'm trying to migration from JUnit4 to JUnit5 and I have a @Rule annotation and I don't exactly know how I can replace this. I tried @ExtendWith but not working for me.

My code with JUnit 4 annotations:

 @Rule public TextReport textReport = new TextReport(); @Rule public BrowserWebDriverContainer chrome = new BrowserWebDriverContainer() .withCapabilities(new ChromeOptions());

Edit: The part of my current code is:

@Testcontainers @ExtendWith(TextReportExtension.class) public class TestBase { @Container public static BrowserWebDriverContainer chrome = new BrowserWebDriverContainer() .withCapabilities(new ChromeOptions()); @Before public void setup() { RemoteWebDriver driver = chrome.getWebDriver(); System.out.println("VNC Address: " + chrome.getVncAddress());

All test classes extends TestBase. And I get an error:

java.lang.IllegalStateException: Mapped port can only be obtained after the container is started

I've updated my answer and I guess the error comes from mixing JUnit 4 & 5 in the same test. — rieckpil

Testcontainers offers JUnit 5 support by adding the following dependency to your project:

<dependency> <groupId>org.testcontainers</groupId> <artifactId>junit-jupiter</artifactId> <version>1.14.3</version> <scope>test</scope> </dependency>

This allows you to refactor BrowserWebDriverContainer to the following:

@Testcontainers public class YourTest { @Container public static BrowserWebDriverContainer chrome = new BrowserWebDriverContainer() .withCapabilities(new ChromeOptions()); }

For the TextReport rule, simply add the following extension from selenide to your class and it will capture the console for you:

@Testcontainers @ExtendWith(TextReportExtension.class) public class YourTest { }

UPDATE: Make sure to always either use JUnit 4 or JUnit 5 in your test. @Before is from JUnit 4, try to replace it with @BeforeEach and ensure your @Test is coming from import org.junit.jupiter.api.Test;.
