19 <h2><a name="assoc_desc" id="assoc_desc">Description</a></h2>
21 <p>The library contains a single comprehensive regression test.
22 For a given container type in <tt>pb_ds</tt>, the test creates
23 an object of the container type and an object of the
24 corresponding STL type (<i>e.g.</i>, <tt>std::set</tt>). It
25 then performs a random sequence of methods with random
26 arguments (<i>e.g.</i>, inserts, erases, and so forth) on both
27 objects. At each operation, the test checks the return value of
28 the method, and optionally both compares <tt>pb_ds</tt>'s
29 object with the STL's object as well as performing other
30 consistency checks on <tt>pb_ds</tt>'s object (<i>e.g.</i>,
31 order preservation, when applicable, or node invariants, when
34 <p>Additionally, the test integrally checks exception safety
35 and resource leaks. This is done as follows. A special
36 allocator type, written for the purpose of the test, both
37 randomly throws an exceptions when allocations are performed,
38 and tracks allocations and de-allocations. The exceptions thrown
39 at allocations simulate memory-allocation failures; the
40 tracking mechanism checks for memory-related bugs (<i>e.g.</i>,
41 resource leaks and multiple de-allocations). Both
42 <tt>pb_ds</tt>'s containers and the containers' value-types are
43 configured to use this allocator.</p>
45 <p>Due to compiler constraints, the test is split into the
46 several sources, each checking only some containers.</p>
