With the move from python 2 to 3 this feature broke because there is no testing for this.
The purpose of this bug is to create tests for the import of tests from other layers. As documented in the Adding New Tests section of the mega-manual. http://www.yoctoproject.org/docs/2.1/mega-manual/mega-manual.html#qemu-image-writing-new-tests The test that has to be created to verify this functionality should do the following things: bitbake add-layer <runtime-testing-layer> configure build for testimage and add the new tests to the TEST_SUITES execute the newly added test
