How was the first release of the JDK Unit?

Can someone explain the following

  • How was the first JDK release module tested? Since Junit came after Java, how did they do it?
  • Are current releases using Junit to validate the JDK API?

The JDK is being tested, at least for now, using jtreg . I do not know how to use JUnit to test JDK.

I assume that the first JDKs (pre Java 1.0) were tested using a harness implemented using other technologies; e.g. C, shell scripts, etc.

Of course, Java testing was done in Java long before JUnit appeared. I remember that in the late 1990s, the infrastructure developed at DSTC was developed at DSTC, and a structure called Mauve was used in the GNU Classpath project. The Java Testing Framework is not rocket science.
