A Class For Test Protocols III

TestProtocol.java

/** * Compare two objects for identity and protocol the result. * * @param testdesc short description of the test. * @param returned object returned by test candidate. * @param expected expected object. */ public void compare(String testdesc, Object returned, Object expected) { ++numberOfTests; if (returned == expected) { protocol += "Passed: "; ++numberOfPassedTests; } else { protocol += "Failed: " + "Got `" + returned + "' but expected `" + expected + "': "; } protocol += testdesc + "\n"; }

The compare methods compare two objects for referential identity and protocol the result.

Tests of identity are helpful in those cases where the identity of a returned object is known in advance. This is true for container classes like stacks.

Note that we rely on the toString() method of objects if we report differences.
