log-testing

Download Build Status License

A simple library for testing log events.

Getting Started

log-testing is available on Maven Central.

<dependency>
    <groupId>com.tyro.oss</groupId>
    <artifactId>log-testing</artifactId>
    <version>2.1</version>
    <scope>test</scope>
</dependency>

A typical test using Logback and JUnit 5 looks like the following. Log4j and JUnit 4 are also supported.

import com.tyro.oss.logtesting.logback.LogbackAssert.Companion.assertThat
import org.junit.jupiter.api.Test
import org.junit.jupiter.api.extension.RegisterExtension
import org.slf4j.LoggerFactory

class ExampleTest {

    private val logger = LoggerFactory.getLogger(ExampleTest::class.java)

    @JvmField
    @RegisterExtension
    val log = LogbackCaptor(ExampleTest::class)

    @Test
    fun `should log message`() {
        logger.info("test message")

        assertThat(log)
                .hasSize(1)
                .hasInfo("test message")
    }
}
