Tests that compare all elements of two traversal objects.
If the user implements the Traversal interface for his own class, the checkExpect still examines the data within the class by comparing the values of the corresponding fields. To invoke the comparison of the data generated by the Traversal iterator, the user needs to use thecheckTraversal (or the inexact variant, the checkInexactTraversal) method.
The class ExamplesTraversals contains all test cases.
Here is the complete source code for this test suite.

Complete test results are shown here.
Here is an example comparing traversal objects.
t.checkTraversal(
songlistTr2, // object 1
songlistTr1, // object 2
"Success: same Traversal-s of songs - shown as Traversal-s"); // test case name
t.checkTraversal(
songlistTr1a, // object 1
songlistTr1, // object 2
"Success: same Traversal-s of songs (different instance of the same data) - shown as Traversal-s"); // test case name
t.checkTraversal(
songlistTr3, // object 1 (2 elements in the list)
songlistTr1, // object 2 (3 elements in the list)
"Should fail: different Traversal-s of songs - first list is shorter"); // test case name
t.checkInexactTraversal(
doubleListTr1, // object 1
doubleListTr2, // object 2
0.001, // tolerance level (too tight)
"Should fail: not exactly equivalent Traversal-s of Double - the tolerance is too tight"); // test case name
t.checkInexactTraversal(
doubleListTr1, // object 1
doubleListTr2, // object 2
0.01, // tolerance level (loose enough)
"Success: not exactly equivalent Traversal-s of Double - the tolerance is loose enough"); // test case name
