Class ScreenshotOnFailureExtension

java.lang.Object
com.vaadin.testbench.ScreenshotOnFailureExtension

All Implemented Interfaces:

org.junit.jupiter.api.extension.Extension, org.junit.jupiter.api.extension.TestWatcher

public class ScreenshotOnFailureExtension extends Object implements org.junit.jupiter.api.extension.TestWatcher

This JUnit extension grabs a screenshot when a test fails. Usage: 

 
 public class MyTestCase extends TestBenchTestCaseJUnit5 {

      \@RegisterExtension public ScreenshotOnFailureExtension screenshotOnFailure = new ScreenshotOnFailureExtension(this, true);

      \@Test public void myTest() throws Exception {
          ...
      }
 }

NOTE! Do NOT call driver.quit() in your tearDown() method (annotated with AfterEach). The tear down method will be run before this extension is run and if the driver is closed it is no longer possible to grab a screen shot of the situation.
