My Logger implementation

<configuration>
<appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>[%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
</appender>
<root level="warn">
    <appender-ref ref="Console" />
</root>

My Logger Class

public class LogManager extends TestBase {
protected static ThreadLocal<StringBuilder> log = ThreadLocal.withInitial(StringBuilder::new);

public static void log(String msg) {
    log.get().append(msg).append("\n");
}

@BeforeSuite(alwaysRun = true)
public void setUp() {
    TestNG testNG = new TestNG();
    testNG.setVerbose(2);
    Logger bonigarcia = (Logger) LoggerFactory.getLogger("io.github.bonigarcia");
    Logger testng = (Logger) LoggerFactory.getLogger("org.testng");
    Logger apache = (Logger) LoggerFactory.getLogger("org.apache");
    Logger slack = (Logger) LoggerFactory.getLogger("com.slack.api");
    Logger gitHub = (Logger) LoggerFactory.getLogger("org.kohsuke");

    bonigarcia.setLevel(Level.WARN);
    testng.setLevel(Level.ERROR);
    apache.setLevel(Level.WARN);
    slack.setLevel(Level.WARN);
    gitHub.setLevel(Level.WARN);
    log.remove();
}

}

I am starting my test suit with mvn command and I can not prevent logging from testng because it runs before my codes. I found that in the testng documentation but I couldn't figure out how to do it.

Starting from TestNG version 7.5 TestNG makes use of the logging facade provided by Slf4j. TestNG by default does not bring in any explicit Slf4j facade implementation. To control the logs being output by TestNG internals, please add a dependency on any suitable Slf4j implementation (Native Or Wrapped implementation) from here

Answer 1

In addition to @Krishnan I updated the pom and logback accordingly and problem solved

pom.xml

<testResources>
        <testResource>
            <directory>src/test/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>*.properties</include>
                <include>*.xml</include>
            </includes>
        </testResource>
    </testResources>

logback.xml

<configuration>
    <appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>[%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <root level="warn">
        <appender-ref ref="Console" />
    </root>
    <logger name="org.testng" level="error">
        <appender-ref ref="Console"/>
    </logger>
</configuration>

Answer 2

You would need to do the following for getting this to work

Add the below to your logback.xml

<logger name="org.testng" level="debug">
  <appender-ref ref="Console"/>
</logger>

The logger is initialised much before the @BeforeSuite is called which perhaps is why the logging levels that you are attempting to set is NOT getting honoured.

But if you set the log levels from your log configuration file (logback.xml in this case) you should be fine!
