Can Selenide take screenshots?

Yes, Selenide takes screenshots automatically on every test failure. This is very useful for error analysis.

By default Selenide puts screenshots to folder build/reports/tests.

Can I tell Selenide to put screenshots to a specific folder?

Yes. You can use property -Dselenide.reportsFolder=test-result/reports to set any directory to store screenshots to. For v4.x use -Dselenide.reports=test-result/reports

Another option is to set this folder directly from your code:

Configuration.reportsFolder = "test-result/reports";

JUnit and TestNG support

For JUnit and TestNG, there is a special support for taking screenshots also on successful tests.

Let me remind: normally you don’t need to setup screenshots in most cases because Selenide automatically takes a screenshot when some of its checks like $.shouldBe(..) fails.

But if you want to also automatically take screenshots

1. in case of successful tests, or
2. if some of non-Selenide check fails (like assertEquals or assertThat),

then you can do it by adding couple of lines. See below.

For JUnit 4:

To automatically take screenshot of every failed test:

import com.codeborne.selenide.junit.ScreenShooter;

public class MyTest {
  @Rule
  public ScreenShooter makeScreenshotOnFailure = ScreenShooter.failedTests();

  // ...
}

To take screenshot of every test (even succeeded), use the following command:

@Rule
public ScreenShooter makeScreenshotOnFailure = ScreenShooter.failedTests().succeededTests();

For TestNG:

import com.codeborne.selenide.testng.ScreenShooter;

@Listeners({ ScreenShooter.class})
public class MyTest {
  // ...
}

To automatically take screenshots after every test (even succeeded), execute the following command before running tests:

ScreenShooter.captureSuccessfulTests = true;

For JUnit 5:

How to use in Java:

  @ExtendWith({ScreenShooterExtension.class})
  public class MyTest {
    // ...
  }

How to use in Java (with customization):

  public class MyTest {
    @RegisterExtension
    static ScreenShooterExtension screenshotEmAll = new ScreenShooterExtension(true).to("target/screenshots");
  }

How to use in Kotlin:

  @ExtendWith(ScreenShooterExtension::class)
  class MyTest {
    // ...
  }

How to use in Kotlin (with customization):

  class MyTest {
    companion object {
      @JvmField
      @RegisterExtension
      val screenshotEmAll: ScreenShooterExtension = ScreenShooterExtension(true).to("target/screenshots");
    }
  }

At any moment you wish

Additionally, you can take screenshot at any moment with a single line of code:

import static com.codeborne.selenide.Selenide.screenshot;

String pngFileName = screenshot("my_file_name");

Selenide will create two files: my_file_name.png & my_file_name.html

Later we also added a method that can return a screenshot in a desired format (BASE64, BYTES or FILE):

String screenshotAsBase64 = Selenide.screenshot(OutputType.BASE64);
byte[] decoded = Base64.getDecoder().decode(screenshotAsBase64);
