在使用 pytest 进行测试时,我们经常需要根据项目的需求进行定制化配置。pytest 提供了丰富的配置选项,使我们可以灵活地调整测试框架的行为。其中,pytest.ini 文件是一种方便的方式来定义和管理 pytest 的配置。本文将详细介绍 pytest.ini 的作用和使用方法,帮助您定制化和管理 pytest 测试框架的配置。
pytest配置文件可以改变pytest的运行方式,它是一个固定的文件pytest.ini文件,读取配置信息,按指定的方式去运行,它有如下作用:
pytest.ini文件的创建和配置
[pytest]
addopts = -s -v
markers =
slow: marks tests as slow
在上面的示例中,我们修改了 addopts
选项,指定了 pytest 的运行参数;并定义了一个名为 "slow" 的标记,用于标记耗时较长的测试。
[pytest]
plugins =
pytest-ordering
在上面的示例中,我们配置了 pytest-ordering 插件,可以控制用例的执行顺序。
全部配置项如下:
[pytest] ini-options in the first pytest.ini|tox.ini|setup.cfg file found:
markers (linelist): markers for test functions
empty_parameter_set_mark (string):
default marker for empty parametersets
norecursedirs (args): directory patterns to avoid for recursion
testpaths (args): directories to search for tests when no files or directories are given in the command line.
filterwarnings (linelist):
Each line specifies a pattern for warnings.filterwarnings. Processed after -W/--pythonwarnings.
usefixtures (args): list of default fixtures to be used with this project
python_files (args): glob-style file patterns for Python test module discovery
python_classes (args):
prefixes or glob names for Python test class discovery
python_functions (args):
prefixes or glob names for Python test function and method discovery
disable_test_id_escaping_and_forfeit_all_rights_to_community_support (bool):
disable string escape non-ascii characters, might cause unwanted side effects(use at your own
risk)
console_output_style (string):
console output: "classic", or with additional progress information ("progress" (percentage) |
"count").
xfail_strict (bool): default for the strict parameter of xfail markers when not given explicitly (default: False)
enable_assertion_pass_hook (bool):
Enables the pytest_assertion_pass hook.Make sure to delete any previously generated pyc cache
files.
junit_suite_name (string):
Test suite name for JUnit report
junit_logging (string):
Write captured log messages to JUnit report: one of no|log|system-out|system-err|out-err|all
junit_log_passing_tests (bool):
Capture log information for passing tests to JUnit report:
junit_duration_report (string):
Duration time to report: one of total|call
junit_family (string):
Emit XML for schema: one of legacy|xunit1|xunit2
doctest_optionflags (args):
option flags for doctests
doctest_encoding (string):
encoding used for doctest files
cache_dir (string): cache directory path.
log_level (string): default value for --log-level
log_format (string): default value for --log-format
log_date_format (string):
default value for --log-date-format
log_cli (bool): enable log display during test run (also known as "live logging").
log_cli_level (string):
default value for --log-cli-level
log_cli_format (string):
default value for --log-cli-format
log_cli_date_format (string):
default value for --log-cli-date-format
log_file (string): default value for --log-file
log_file_level (string):
default value for --log-file-level
log_file_format (string):
default value for --log-file-format
log_file_date_format (string):
default value for --log-file-date-format
log_auto_indent (string):
default value for --log-auto-indent
pythonpath (paths): Add paths to sys.path
faulthandler_timeout (string):
Dump the traceback of all threads if a test takes more than TIMEOUT seconds to finish.
addopts (args): extra command line options
minversion (string): minimally required pytest version
required_plugins (args):
plugins that must be present for pytest to run
environment variables:
PYTEST_ADDOPTS extra command line options
PYTEST_PLUGINS comma-separated plugins to load during startup
PYTEST_DISABLE_PLUGIN_AUTOLOAD set to disable plugin auto-loading
PYTEST_DEBUG set to enable debug tracing of pytest's internals
pytest.ini文件如下:
[pytest]
addopts = -vs
被测程序如下:
class Calculator:
def add(self, a, b):
if a > 99 or a < -99 or b > 99 or b < -99:
print("请输入范围为【-99, 99】的整数或浮点数")
return "参数大小超出范围"
return a + b
def div(self, a, b):
if a > 99 or a < -99 or b > 99 or b < -99:
print("请输入范围为【-99, 99】的整数或浮点数")
return "参数大小超出范围"
return a / b
测试脚本如下:
class TestCalc:
def setup(self):
self.calc=Calculator()
def test_add1(self):
result = self.calc.add(1, 1)
print(f"实际结果为:{result}")
expect = 2
assert result == expect
def test_add2(self):
result = self.calc.add(-0.01, 0.02)
print(f"实际结果为:{result}")
# 期望结果
expect = 0.01
# 断言
assert result == expect
def test_div1(self):
result = self.calc.div(1,1)
assert result == 1
def test_div2(self):
try:
result = self.calc.div(1,0)
except ZeroDivisionError as e:
print(f'除数为0{e}')
assert False
输出结果如下图:
pytest.ini 文件是 pytest 的一个强大特性,可以帮助我们定制化和管理 pytest 测试框架的配置。通过定义和修改 pytest 的配置选项,我们可以灵活调整测试运行环境、插件设置、标记规则和报告输出等,以满足项目的需求。
在本文中,我们介绍了 pytest.ini 文件的作用和使用方法。现在您可以创建自己的 pytest.ini 文件,并根据项目的需求进行定制化配置了。享受 pytest 提供的灵活性和便利性,提高测试的效率和质量吧!
