Cleaning up output from Console

[kazurayam]

1. Can we control if println appears on the Log Viewer,

No, I don’t think it is possible.

or is that locked to com.kms methods like KeyWordUtil only?

Yes, almost.

What determines if something gets displayed on the Log Viewer?

com.kms.katalon.core.util.KeywordUtil calls com.kms.katalon.core.logging.KeywordLogger, where you can find ultimately org.slf4j.Logger is used.The LogViewer in the KS GUI seems displaying the logs recorded through the SLF4J logging infrastructure. Therefore, any output through System.out.println does not come up to the LogViewer. I believe KS uses the Logback as an implementation backing the SLF4J interface.

2. I find that the Console cuts off after a certain number of lines. Can we view the entirety of Console Logs, or at least view the log file in our filesystem?

Please have a look at my previous posts.

How can I change the message format of WebUI.comment("msg")? + logging into FILE

I am using Katalon Studio 5.10.1 on Windows 7 Problem to solve When I run this test case: import com.kms.katalon.core.webui.keyword.WebUiBuiltInKeywords as WebUI def arg0 = 2 def arg1 = 3 def result = arg0 + arg1 WebUI.comment("arg0 + arg1 = ${result}") I get the following output in the Console: 2019-01-11 11:28:35.018 INFO c.k.katalon.core.main.TestCaseExecutor - -------------------- 2019-01-11 11:28:35.034 INFO c.k.katalon.core.main.TestCaseExecutor - START Test Cases/AdditionDemo 201…

Write the sl4J logs into a text file

Katalon Studio uses the logback as the implementation of the slf4j interface. Some articles on the web explains how to use SLF4J and Logback. For example, please refer to: Once I have ever tried to change the logback configuration in Katalon Studio. See the following post:. In this post, I tried to change the format of log messages by modifying the logback configuration. Similarly you can add new appender which writes message into file by modifying the logback configuration. Here I just men…

There is a way for you. You can write a Custom Keyword that modifies the LogBack configuration dynamically. If you do it, you can customize the logging behavior of KS runtime.

It is a hard practice, easily broken, difficult to keep stable. I suppose that Katalon Team is reluctant to offer a feature of customizing LogBack configuration due to the same reason. If a less-skillful user break the logging feature in KS, he/she can not debug it at all because no log is visible.

As far as I see, KS is a product oriented for beginners and novices, not for programming experts. So I would not stick to the customization offering too much. If I personally want to, I can make it anyway…
