Running GWT JUnit on Eclipse

[Pion]

I am following the instructions on http://code.google.com/webtoolkit/tutorials/1.6/JUnit.html.
I can run the junit successfully using command line. My environments
are: Eclipse-Galileo, GWT SDK 1.7 on Windows Vista.

However, I am having problem when trying to run it on Eclipse. Eclipse
gave me the following error message: "The input type of the launch
configuration does not exist".

I tried to follow the instructions on http://code.google.com/eclipse/docs/gwt_junit.html.
My Eclipse "Run" button is disabled -- I can not click it.

Thanks in advance for your help.

Hi Pion,

Did the error you described ("The input type of the launch configuration does not exist") come when you were following the StockWatcher test instructions or the Google Plugin for Eclipse test instructions?

What error did you run into when you tried the Google Plugin for Eclipse test instructions (the second URL you mentioned)?

Thanks
jason

I got the error when following the instructions on
http://code.google.com/webtoolkit/tutorials/1.6/JUnit.html.

Following http://code.google.com/eclipse/docs/gwt_junit.html did not
give me any error. I went to Eclipse "Run -> Run Configurations ... "
which display a dialog box. But the "Run" button (on the dialog box)
has been disabled so I cannot run it.

Could you try right-clicking on your test class and choosing Run as -> GWT Test case?

Thanks,

I right-click on my java test file and select "Run As -> GWT Junit
Test". Then, I got the following error: "The input type of the launch

configuration does not exist".

Strange!  Could you send us the contents of your WORKSPACE/.metadata/.log file?  It might have more detailed information about the error.

Thanks

Sorry for the late reply. I just returned to my desk.

Where can I find those info? Can you give me more specific examples? I
can't seem to find them.

No problem!

If you open your Eclipse workspace folder, there should be a folder called ".metadata".  Inside that, there should be a file called ".log".

I believe Windows hides these files by default, so you may need to use the command prompt to find this file (either that, or turn on the setting to show hidden files -- see http://windowshelp.microsoft.com/Windows/en-US/help/27e9a81a-fac7-457f-896b-e0017a04a59f1033.mspx )

If neither the file nor folder are present, then there may not be any detailed error logs.

Unfortunately, there is no .metadata folder.

There are .settings, .classpath and .project.

Hi Pion,

Could you try the steps below?  I performed these locally and found success.

1) Extract GettingStarted.zip somewhere

2) Eclipse's File > Import > General > Existing projects, choose the extracted StockWatcher directory

3) Right-click on the StockWatcher project, and choose Properties.  Click on Google > Web Toolkit (on the side bar), and confirm there is a GWT SDK set for this project

4) Java Build Path, Libraries tab, Add Library button, JUnit from list, Next button, ensure JUnit 3 is being used, and Finish button and then OK button

5) Right-click on StockWatcher project, New > Source Folder named "test"

6) Create a package in there named "com.google.gwt.sample.stockwatcher.client"

7) Finally, paste the contents below into a new class in that package (named StockWatcherTest.java)

8) Right-click on this class, choose Run As > GWT JUnit Test

If I've screwed up anywhere in these directions, please let me know.  Hope this works!

jason

package com.google.gwt.sample.stockwatcher.client;

import com.google.gwt.junit.client.GWTTestCase;

/**

 * GWT JUnit tests must extend GWTTestCase.

 */

public class StockWatcherTest extends GWTTestCase {

/**

* Must refer to a valid module that sources this class.

*/

public String getModuleName() {

return "com.google.gwt.sample.stockwatcher.StockWatcher";

}

/**

* Add as many tests as you like.

*/

public void testSimple() {

assertTrue(true);

}

}

Thanks, Jason. I really appreciate your help.

I just followed your step-by-step instructions below. Unfortunately,
It still give me "The input type of the launch

configuration does not exist".

Also, I right-click the StockWatcherTest.java and select "Run As ->
Run Configurations", it shows the dialog box and the "Run" button is
disabled.

I don't know if this info will be helpful to you. This morning, I
created a unit test successfully on Eclipse-Galileo for my Google App
Engine by doing the following:

o I created a package com.foo.server.test under src
o Right-click on the package com.foo.server.test, select "New ->
Other ... -> JUnit Test Case ".
o I can run on Eclipse successfully.
o Also, the "Run" button is enabled when I went to "Run As -> Run
Configurations".

Again, thanks for your help.

Jason,
I think I found what my problem was. Your step " 5) Right-click on
StockWatcher project, New > Source Folder named "test"" is the key.

It has to be "Source Folder" -- Just "Folder" will screw things up.

When I right-click the test java file, "Run As -> Run
Configurations ...", the "Run" button is enabled.
Also, I can run the Junit by right-click the test java file "Run As ->
GWT JUnit Test".

Again, thanks for your help! You are the BEST!
