Test Expressions

The most important thing is to write tests like

    (expectedResult == obtainedResult)

or

    expectedResult.equals(obtainedResult)

You can do that without JUnit, of course. For the purpose of this document, I will call the smallest unit of testing, like the expression above, a test expression . All that JUnit does is give you flexibility in grouping your test expressions and convenient ways to capture and/or summarize test failures.
