Due to a technical difficulties we have to build a version of a testrunner that binds specifically to certain NetBeans versions. As a result there are three NBMs of Android Test Runner module. One works with NetBeans 6.9 the second with 6.9.1 and the last will work with 7.0 and future builds (I tested it with NetBeans 7.0RC2). When installing from our continuous build select 'Android' and one of the 'Android Test Runner for NetBeans x.y'. Similarly if you want to install from ZIP archive select all NBM files but those that do not match your IDE version. This should not be hard and AutoUpdate support will not allow you to install the version that is not compatible with your version in next step anyway.
The latest build tagged as 1.5beta is now available for download from Kenai hosting.
