JUnit changes from 2.7 to 2.8

[Byron Ludwig]

Hi,

Could someone please explain how GWT now compiles and runs JUnit test cases as I have just upgraded my code base from 2.7 to 2.8.2 and now none of my GWT test cases work.

What has changed between releases? I can now see it trys to compile the project like a normal startup and this never occurred before.

Everything else is working after upgrading and my application compiles and runs perfectly fine, just not the test cases.

Here is the exception I am getting but I cannot make heads or tails where the actual error is?

Any help is appreciated.

See http://www.gwtproject.org/release-notes.html#Release_Notes_2_8_0_RC1

Specifically, in the "deprecations" section: “Classic dev mode deprecated.You can switch back to dev mode for your test cases temporarily by passing gwt.args=‘-devMode’.”

 

Everything else is working after upgrading and my application compiles and runs perfectly fine, just not the test cases.

Here is the exception I am getting but I cannot make heads or tails where the actual error is?

Try passing -strict (or -failOnError) and/or -draft in the gwt.args system property.

[Byron Ludwig]

Thanks for the reply. 

Do you know how I add those in Eclipse? I also note that I cannot edit the arguments in Eclipse as there is an existing issue:

https://github.com/gwt-plugins/gwt-eclipse-plugin/issues/168

Is there another way to set these?

[Byron Ludwig]

I fixed the issue with the GWT plugin and was able to set the -devMode flag as a VM Argument.

It now works.

Thanks for the help.
