AbstractAssert
// compares invoices by payee assertThat(invoiceList).usingComparator(invoicePayeeComparator).isEqualTo(expectedInvoiceList). // compares invoices by date, doesNotHaveDuplicates and contains both use the given invoice date comparator assertThat(invoiceList).usingComparator(invoiceDateComparator).doesNotHaveDuplicates().contains(may2010Invoice) // as assertThat(invoiceList) creates a new assertion, it uses standard comparison strategy (Invoice's equal method) to compare invoiceList elements to lowestInvoice. assertThat(invoiceList).contains(lowestInvoice).Custom comparator is not parameterized with actual type A (ie. Comparator<A>) because if it was, we could not write the following code :
// frodo and sam are instances of Character (a Character having a Race) // raceComparator implements Comparator<Character> // assertThat(frodo) returns an ObjectAssert and not a custom CharacterAssert implementing Assert<CharacterAssert, Character> assertThat(frodo).usingComparator(raceComparator).isEqualTo(sam); // won't compile ! The code does not compile because assertThat(frodo) returns an ObjectAssert, thus usingComparator expects a Comparator<Object> and Comparator<Character> is not a Comparator<Object> as generics are not reified. Note that, it would have worked if assertThat(frodo) returned a CharacterAssert implementing Assert<CharacterAssert, Character>.
