    Class used to record warnings for unit tests. See documentation of
    :func:`check_warnings` above for more details.

+===================================
+
+.. module:: test.support.bytecode_helper
+   :synopsis: Support tools for testing correct bytecode generation
+
+
+This module defines the following class:
+
+.. class:: BytecodeTestCase()
+
+   Class used to provide custom assertion methods for inspecting bytecode.
+
+.. method:: BytecodeTestCase.get_disassembly_as_string(co)
+
+.. method:: BytecodeTestCase.assertInstructionMatches(instr, expected, *, line_offset=0)
+
+.. method:: BytecodeTestCase.assertBytecodeExactlyMatches(x, expected, *, line_offset=0)
+
+   Throws AssertionError if any discrepancy is found in bytecode
+
+   *x* is the object to be introspected
+   *expected* is a list of dis.Instruction objects
+
+   Set *line_offset* as appropriate to adjust for the location of the
+   object to be disassembled within the test file. If the expected list
+   assumes the first line is line 1, then an appropriate offset would be
+   ``1 - f.__code__.co_firstlineno``.
+
+
+
+.. method:: BytecodeTestCase.assertInBytecode(x, opname, argval=object())
+
+   Returns a dis.Instruction object if *opname* is found, otherwise throws AssertionError.
+
+
+.. method:: BytecodeTestCase.assertNotInBytecode(x, opname, argval=object())
+
+   Throws AssertionError if *opname* is found.
