  public void verifyAll(Closure closure){
    GroovyRuntimeUtil.invokeClosure(closure);
  }
All assertions in this block are executed and the errors recorded and reported at the end.

<p>Example:

<pre>
expect:
verifyAll {
  1 == 2
  2 == 3
}
</pre>

This will report two errors, instead of just the first.
