vscode中配置pytest
在测试用例中使用print的设置方法
在setting.json中输入一下内容：
"python.testing.pytestArgs": [ ".", # 初始值为所有，理论上有了下面的，就不应该有该项目？可以考虑存在和不存在，查看对测试结果的影响 "--capture=no", # 表示控制台可以print输出
"-q", # 表示简化输出
"-disable-warnings" # 表示不显示警告信息
], "python.testing.unittestEnabled": false, "python.testing.nosetestsEnabled": false, "python.testing.pytestEnabled": true, "python.testing.promptToConfigure": false, "python.testing.autoTestDiscoverOnSaveEnabled": false,
其中："--capture=no"表示pytest不捕获测试用例中的print，那么在测试用例使用print时，就可以直接在控制台显示出来
介绍几个常用的参数：
-q: 简化结果信息，不会显示每个用例的文件名等；-s：允许在结果中显示标准输出，比如你在用例中的打印信息，默认在结果中不会显示标准输出；--capture=no：与-s效果一样，主要演示一下带参数值的写法；-m mark：指定带相应标记的用例。用于演示不带等号的参数写法。
禁用警告信息
--disable-warnings
在python.testing.pytestArgs中添加如上信息，就可以禁用警告信息了。
若是想了解pytest中所有的命令行信息，可以使用：pytest --help，内容如下：
usage: pytest [options] [file_or_dir] [file_or_dir] [...] positional arguments: file_or_dir general: -k EXPRESSION only run tests which match the given substring expression. An expression is a python evaluatable expression where all names are substring-matched against test names and their parent classes. Example: -k 'test_method or test_other' matches all test functions and classes whose name contains 'test_method' or 'test_other', while -k 'not test_method' matches those that don't contain 'test_method' in their names. -k 'not test_method and not test_other' will eliminate the matches. Additionally keywords are matched to classes and functions containing extra names in their 'extra_keyword_matches' set, as well as functions which have names assigned directly to them. -m MARKEXPR only run tests matching given mark expression. example: -m 'mark1 and not mark2'. --markers show markers (builtin, plugin and per-project ones). -x, --exitfirst exit instantly on first error or failed test. --maxfail=num exit after first num failures or errors. --strict-markers, --strict markers not registered in the `markers` section of the configuration file raise errors. -c file load configuration from `file` instead of trying to locate one of the implicit configuration files. --continue-on-collection-errors Force test execution even if collection errors occur. --rootdir=ROOTDIR Define root directory for tests. Can be relative path: 'root_dir', './root_dir', 'root_dir/another_dir/'; absolute path: '/home/user/root_dir'; path with variables: '$HOME/root_dir'. --fixtures, --funcargs show available fixtures, sorted by plugin appearance (fixtures with leading '_' are only shown with '-v') --fixtures-per-test show fixtures per test --import-mode={prepend,append} prepend/append to sys.path when importing test modules, default is to prepend. --pdb start the interactive Python debugger on errors or KeyboardInterrupt. --pdbcls=modulename:classname start a custom interactive Python debugger on errors. For example: --pdbcls=IPython.terminal.debugger:TerminalPdb --trace Immediately break when running each test. --capture=method per-test capturing method: one of fd|sys|no. -s shortcut for --capture=no. --runxfail report the results of xfail tests as if they were not marked --lf, --last-failed rerun only the tests that failed at the last run (or all if none failed) --ff, --failed-first run all tests but run the last failures first. This may re-order tests and thus lead to repeated fixture setup/teardown --nf, --new-first run tests from new files first, then the rest of the tests sorted by file mtime --cache-show=[CACHESHOW] show cache contents, don't perform collection or tests. Optional argument: glob (default: '*'). --cache-clear remove all cache contents at start of test run. --lfnf={all,none}, --last-failed-no-failures={all,none} which tests to run with no previously (known) failures. --sw, --stepwise exit on test failure and continue from last failing test next time --stepwise-skip ignore the first failing test but stop on the next failing test --arraydiff Enable comparison of arrays to reference arrays stored in files --arraydiff-generate-path=ARRAYDIFF_GENERATE_PATH directory to generate reference files in, relative to location where py.test is run --arraydiff-reference-path=ARRAYDIFF_REFERENCE_PATH directory containing reference files, relative to location where py.test is run --arraydiff-default-format=ARRAYDIFF_DEFAULT_FORMAT Default format for the reference arrays (can be 'fits' or 'text' currently) reporting: --durations=N show N slowest setup/test durations (N=0 for all). -v, --verbose increase verbosity. -q, --quiet decrease verbosity. --verbosity=VERBOSE set verbosity. Default is 0. -r chars show extra test summary info as specified by chars: (f)ailed, (E)rror, (s)kipped, (x)failed, (X)passed, (p)assed, (P)assed with output, (a)ll except passed (p/P), or (A)ll. (w)arnings are enabled by default (see --disable-warnings). --disable-warnings, --disable-pytest-warnings disable warnings summary -l, --showlocals show locals in tracebacks (disabled by default). --tb=style traceback print mode (auto/long/short/line/native/no). --show-capture={no,stdout,stderr,log,all} Controls how captured stdout/stderr/log is shown on failed tests. Default is 'all'. --full-trace don't cut any tracebacks (default is to cut). --color=color color terminal output (yes/no/auto). --pastebin=mode send failed|all info to bpaste.net pastebin service. --junit-xml=path create junit-xml style report file at given path. --junit-prefix=str prepend prefix to classnames in junit-xml output --result-log=path DEPRECATED path for machine-readable result log. collection: --collect-only, --co only collect tests, don't execute them. --pyargs try to interpret all arguments as python packages. --ignore=path ignore path during collection (multi-allowed). --ignore-glob=path ignore path pattern during collection (multi-allowed). --deselect=nodeid_prefix deselect item during collection (multi-allowed). --confcutdir=dir only load conftest.py's relative to specified dir. --noconftest Don't load any conftest.py files. --keep-duplicates Keep duplicate tests. --collect-in-virtualenv Don't ignore tests in a local virtualenv directory --doctest-modules run doctests in all .py modules --doctest-report={none,cdiff,ndiff,udiff,only_first_failure} choose another output format for diffs on doctest failure --doctest-glob=pat doctests file matching pattern, default: test*.txt --doctest-ignore-import-errors ignore doctest ImportErrors --doctest-continue-on-failure for a given doctest, continue to run after the first failure test session debugging and configuration: --basetemp=dir base temporary directory for this test run.(warning: this directory is removed if it exists) --version display pytest lib version and import information. -h, --help show help message and configuration info -p name early-load given plugin module name or entry point (multi-allowed). To avoid loading of plugins, use the `no:` prefix, e.g. `no:doctest`. --trace-config trace considerations of conftest.py files. --debug store internal tracing debug information in 'pytestdebug.log'. -o OVERRIDE_INI, --override-ini=OVERRIDE_INI override ini option with "option=value" style, e.g. `-o xfail_strict=True -o cache_dir=cache`. --assert=MODE Control assertion debugging tools. 'plain' performs no assertion debugging. 'rewrite' (the default) rewrites assert statements in test modules on import to provide assert expression information. --setup-only only setup fixtures, do not execute tests. --setup-show show setup of fixtures while executing tests. --setup-plan show what fixtures and tests would be executed but don't execute anything. pytest-warnings: -W PYTHONWARNINGS, --pythonwarnings=PYTHONWARNINGS set which warnings to report, see -W option of python itself. logging: --no-print-logs disable printing caught logs on failed tests. --log-level=LOG_LEVEL logging level used by the logging module --log-format=LOG_FORMAT log format as used by the logging module. --log-date-format=LOG_DATE_FORMAT log date format as used by the logging module. --log-cli-level=LOG_CLI_LEVEL cli logging level. --log-cli-format=LOG_CLI_FORMAT log format as used by the logging module. --log-cli-date-format=LOG_CLI_DATE_FORMAT log date format as used by the logging module. --log-file=LOG_FILE path to a file when logging will be written to. --log-file-level=LOG_FILE_LEVEL log file logging level. --log-file-format=LOG_FILE_FORMAT log format as used by the logging module. --log-file-date-format=LOG_FILE_DATE_FORMAT log date format as used by the logging module. --log-auto-indent=LOG_AUTO_INDENT Auto-indent multiline messages passed to the logging module. Accepts true|on, false|off or an integer.
