Create test sets to test different implementations of the same interface

Installation

\$ pip install nose-test-sets

Usage

To define your set of common tests, create a TestSetBuilder, and use add_test to add tests. Each test should accept the same name of arguments. Say you define some tests for an adder in the module adder_test_set:

from nose_test_sets import TestSetBuilder

test_set_builder = TestSetBuilder()

@test

@test

create = test_set_builder.create

To run the tests against a specific implementation, you create a set of tests using the create function that we defined above:

import adder_test_set

)

The first argument to create should be the name of the concrete test set. The second argument is a function that can run each of the test functions. In the example above, to run the tests in StandardAdderTests, nose-test-sets ends up calling _run_test_with_standard_adder(adding_zero_to_zero_returns_zero) and _run_test_with_standard_adder(adding_one_to_two_returns_three).
