Functional Programming in Java, Second Edition: p. 117, Nitpicking "verbose test"
In the given “old-school” test for the generation of an exception:
@Test public void VerboseExceptionTest() {
rodCutter.setPrices(prices);
try {
rodCutter.maxProfit(0);
fail("Expected exception for zero length");
} catch(RodCutterException ex) {
assertTrue(true);
}
}
- The name of the method is capitalized
- The purpose of
assertTrue(true)is unclear. Is there just for documentation? One would write a statement likeassertTrue(someComplexBooleanExpression)butassertTrue(true)does nothing.

Thank you, David. Good catch on the method name. Fixed it.
The assertTrue is to avoid empty catch block or a comment to say that it is intended.
