Unable to debug my gwt test case in eclipse

[deba...@ainosoft.com]

Hi guys,

Somehow I am unable to understand our lack of interest in supporting Java based debugging for GWT test cases. (devmode is deprecated )

I followed the workaround suggested in the release notes and got to a point where it does try to execute the test without compiling to JavaScript. But got an exception. The detailed exception message is attached as a text file. 

Aug 16, 2017 1:13:38 PM com.gargoylesoftware.htmlunit.WebConsole info
INFO: /launch error: Failed to load module com.ainosoft.deba.Gwt_2_8_1_learningJUnit.JUnit: undefined

I passed the -Dgwt.args="devMode" to the JUnit test configuration. 

Can someone help me out ?

thanks a lot,

Debasish

Found a simple solution - 

Add this line to your Junit.gwt.xml file after you configure you pass this -Dgwt.args="-devMode" as your VM argument. You will also need to add your src/main/java src/test/java to your run configuration classpath explicitly. 

<set-property name="user.agent" value="gecko1_8" />

Somehow there is no default user agent used in the JUnitShell responsible for running the test.
