Title: Standard for testing on the JVM
Length: Short
> There is no standard for testing on the JVM: the only common

Copied from
<>entest4j  -- which
expounds on the history, motivation, goal and benefits of such a
standard for testing on the JVM. Here's another quote:

> The primary goal of the project is to enable testing frameworks

> like Hamcrest, AssertJ, etc. to use a common set of exceptions

> visualization of test execution in IDEs and reports.

I propose to supersede that project by integrating the few error
and exception classes into the core of the JDK for the benefit
of the greater Java community.

Perhaps by creating a package in module "java.base", e.g.
"java.lang.assertion" as the container of those errors and exceptions.

Or introduce a dedicated "java.test" module? Which, later, might
also host the platform for testing on the JVM. More on that idea
can be found here:
