Groovy Eclipse can't launch junit tests

Question

In Eclipse with groovy plugin, I try to launch a test @Test public void testToLaunch() {...} but I have the error:

The input type of the launch configuration does not exist

What input type is in the context of launch configuration? (can't find such an entry in launch configuration window)

Note: I try sts 2.8.1 and e3.7

Answer 1

This can also happen if there is a problem with the groovy class. A few things to check:

1) Ensure that the class name exactly matches the filename (filename = MyTest.groovy)

package com.mypackage;
import groovy.util.GroovyTestCase;

class MyTest extends GroovyTestCase {}

2) Ensure that the package defined in the file matches the package the file is actually in.

Answer 2

This happens normally when the folder in which test case is present is not a source folder, please check this post as well. Hope that helps!

Answer 3

In Eclipse you can do

Right click ->  properties -> Java build path

Notice test folder is not available in sources. Add it.

Add folder -> Select test -> OK

Now rerun you unit test cases.
