CapturedOutput

interface CapturedOutput : CharSequence

Provides access to System.out and System.err output that has been captured by the OutputCaptureExtension or OutputCaptureRule. Can be used to apply assertions either using AssertJ or standard JUnit assertions. For example:

assertThat(output).contains("started"); // Checks all output
assertThat(output.getErr()).contains("failed"); // Only checks System.err
assertThat(output.getOut()).contains("ok"); // Only checks System.out
