测试类内部,属性传递
import pytest class Test_Case: t = 0 def test_c(self): self.t = self.t + 1 assert self.t == 1 def test_d(self): self.t = self.t + 1 assert self.t == 1 # t是测试类的属性,可以为所有测试方法共享该值,该值是固定不变的
global方式传递
import pytest s = {} class Test_Case: def test_b(self): global s s['name'] = 'hello' print(s['name']) assert s['name'] == 'hello' def test_c(self): global s s['age'] = 18 print(s) assert s['age'] == 18 # global声明的变量可以在整个测试类中共享,值是可变的,global可以去掉,效果相同
@pytest.mark.parametrize()
import pytest class Test_Case: @pytest.mark.parametrize("x", [1, 2, 3, 4]) # 传递单个值 def test_b(self, x): assert x != 5 @pytest.mark.parametrize("x,y", [(1, 2), (3, 4), (2, 3), (4, 6)]) # 多参数,传递元组 def test_c(self, x, y): print(x + y) assert x + y != 5 @pytest.mark.parametrize("x,y", [{1, 2}, {3, 4}, {2, 3}, {4, 6}]) # 多参数传递集合 def test_d(self, x, y): print(x + y) assert x + y != 6 @pytest.mark.parametrize("x", [{"a": 1, "b": 2}, {"a": 1, "c": 4}]) # 传递字典 def test_e(self, x): print(x) assert x["a"] == 1 @pytest.mark.parametrize("x,y", [({"a": 1, "b": 2}, {"a": 3, "c": 4})]) # 多参数传递字典 def test_f(self, x, y): assert x["a"] == 1 @pytest.mark.parametrize("x", [{"a": 1, "b": 2}]) # 装饰器叠加,传递多参数 @pytest.mark.parametrize("y", [{"a": 1, "b": 2}]) def test_g(self, x, y): assert y["a"] == 1 @pytest.mark.parametrize( "test_input,expected", [("3+5", 8), ("2+4", 6), pytest.param("6*9", 42, marks=pytest.mark.xfail)], ) # xfail标记 def test_h(self, test_input, expected): assert eval(test_input) == expected @pytest.mark.parametrize( "test_input,expected", [("3+5", 8), ("2+4", 6), pytest.param("6*9", 42, marks=pytest.mark.skip)], ) # skip标记 def test_i(self, test_input, expected): assert eval(test_input) == expected
fixtrue传递
import pytest class Test_Case: @pytest.fixture def get_d(self): # 通过fixture值传递 return [1, 2, 3] def test_a(self, get_d): x = get_d[0] assert x == 1
import pytest class Test_Case: # params = 'hello'等同于params = ['h','e','l','l','o'] @pytest.fixture(params='hello') def get_c(self, request): print(request.param) return request.param def test_c(self, get_c): name = get_c assert name == 'h' @pytest.fixture(params=[1, 2], ids=['hello', 'name']) # 可以通过pytest -k <ids>执行指定的用例 def get_d(self, request): return request.param def test_d(self, get_d): name = get_d assert name == 2 @pytest.fixture(params=[0, 1, pytest.param(2, marks=pytest.mark.skip)]) def data_set(self, request): return request.param def test_f(self): pass
import pytest #fixture嵌套传递 class Test_Case: @pytest.fixture(params=[0, 1, pytest.param(2, marks=pytest.mark.skip)]) def data_set(self, request): return request.param @pytest.fixture() def data_s(self, data_set): print(data_set) return data_set def test_g(self, data_s): assert data_s == 1
# yield传递 import pytest class Test_Case: @pytest.fixture def s(self): c = 'test' yield c def test_name(self, s): assert s == "test"
配置文件传递
# test_case.py import pytest import _case.constant as d class Test_Case: def test_g(self): d.data = 2 assert d.data == 2 def test_h(self): assert d.data == 2 # _case.constant.py data = 1 # 和global使用类似,多个测试文件共享值,但是多个文件共享该值时,会收到测试文件的执行顺序影响 # global只能在一个测试文件中共享值
conftest.py
# conftest.py最好是在项目根目录或者测试文件所在目录 import pytest @pytest.fixture(scope='session') def say(): return 'hello' # test_case.py import pytest class Test_Case: def test_g(self, say): assert say == 'hello'
命令行参数传参
# conftest.py 全局变量使用 import pytest def pytest_addoption(parser): parser.addoption("--file", default="test") @pytest.fixture def file_name(request): return request.config.getoption("--file") # test_case.py import pytest class Test_Case: def test_name(self, file_name): assert file_name == "test" # test_case.py或者直接在测试文件中通过pytestconfig获取,示例如下 def test_name(self, pytestconfig): print(pytestconfig.getoption('file')) assert pytestconfig.getoption("file") == "test"
钩子函数传参
# conftest.py import pytest def pytest_addoption(parser): parser.addoption("--file", default="test") def pytest_generate_tests(metafunc): file = metafunc.config.getoption('--file') metafunc.parametrize("case_data", [file]) # test_case.py import pytest class Test_Case: def test_g(self, case_data): assert case_data == 'test'
