All Implemented Interfaces:
org.junit.jupiter.api.extension.AfterAllCallback, org.junit.jupiter.api.extension.AfterEachCallback, org.junit.jupiter.api.extension.BeforeAllCallback, org.junit.jupiter.api.extension.BeforeEachCallback, org.junit.jupiter.api.extension.Extension, org.junit.jupiter.api.extension.ParameterResolver
public class LogCaptorExtension extends Object implements org.junit.jupiter.api.extension.BeforeAllCallback, org.junit.jupiter.api.extension.BeforeEachCallback, org.junit.jupiter.api.extension.AfterAllCallback, org.junit.jupiter.api.extension.AfterEachCallback, org.junit.jupiter.api.extension.ParameterResolver
A JUnit 5 extension to capture logs during tests.

This extension will capture all logs during a test and make them available for assertions.

When using this extension, you should annotate your test class with either WithLogCapture or @ExtendWith(LogCaptorExtension.class).

When using this extension, you can inject a LogCaptor into your test methods. This will contain all logs captured during the test. The log level and log events are reset after each test.

Example code: 

 
 @WithLogCapture
 class MyTest {
     // LogCaptor is automatically injected by the extension
     @Test
     void test(LogCaptor logCaptor) {
         // Your test code here
     }
 }

By default, captured logs are not written to the console. If you want to see the logs in the console, you can use LogCaptor.enableConsoleOutput(). Note that this will need to be done in each test.
