java - what is the purpose of assertThat in JDBI? -

-

i going through codebase found in github. found set of lines in code contains following function:assertthat.any appreciated.

 myobject = somedao.foo(obj);  assertthat(myobject.getupdated,isafter(updated));

this assertion lib called hamcrest used ensure states in program. if fail throw exception output understanding goes wrong. assert or assertequals methods junit. , used in test class can use them in normal program ensure states expect (preconditions, postconditions,class invariants or design contract).

so ensures date getupdated> date updated when wrong exception thrown.
