Playwright Test的完整选项集可在配置文件中找到。以下选项可以通过命令行传递，并优先于配置文件：

Option	Description
Non-option arguments	Each argument is treated as a regular expression matched against the full test file path. Only tests from files matching the pattern will be executed. Special symbols like $ or * should be escaped with \. In many shells/terminals you may need to quote the arguments.
-c <file> or --config <file>	Configuration file, or a test directory with optional "playwright.config.{m,c}?{js,ts}". Defaults to playwright.config.ts or playwright.config.js in the current directory.
--debug	Run tests with Playwright Inspector. Shortcut for PWDEBUG=1 environment variable and --timeout=0 --max-failures=1 --headed --workers=1 options.
--fail-on-flaky-tests	Fail if any test is flagged as flaky (default: false).
--forbid-only	Fail if test.only is called (default: false). Useful on CI.
--fully-parallel	Run all tests in parallel (default: false).
--global-timeout <timeout>	Maximum time this test suite can run in milliseconds (default: unlimited).
-g <grep> or --grep <grep>	Only run tests matching this regular expression (default: ".*").
-gv <grep> or --grep-invert <grep>	Only run tests that do not match this regular expression.
--headed	Run tests in headed browsers (default: headless).
--ignore-snapshots	Ignore screenshot and snapshot expectations.
--last-failed	Only re-run the failures.
--list	Collect all the tests and report them, but do not run.
--max-failures <N> or -x	Stop after the first N failures. Passing -x stops after the first failure.
--no-deps	Do not run project dependencies.
--output <dir>	Folder for output artifacts (default: "test-results").
--only-changed [ref]	Only run test files that have been changed between 'HEAD' and 'ref'. Defaults to running all uncommitted changes. Only supports Git.
--pass-with-no-tests	Makes test run succeed even if no tests were found.
--project <project-name...>	Only run tests from the specified list of projects, supports '*' wildcard (default: run all projects).
--quiet	Suppress stdio.
--repeat-each <N>	Run each test N times (default: 1).
--reporter <reporter>	Reporter to use, comma-separated, can be "dot", "line", "list", or others (default: "list"). You can also pass a path to a custom reporter file.
--retries <retries>	Maximum retry count for flaky tests, zero for no retries (default: no retries).
--shard <shard>	Shard tests and execute only the selected shard, specified in the form "current/all", 1-based, e.g., "3/5".
--timeout <timeout>	Specify test timeout threshold in milliseconds, zero for unlimited (default: 30 seconds).
--trace <mode>	Force tracing mode, can be "on", "off", "on-first-retry", "on-all-retries", "retain-on-failure", "retain-on-first-failure".
--tsconfig <path>	Path to a single tsconfig applicable to all imported files (default: look up tsconfig for each imported file separately).
--ui	Run tests in interactive UI mode.
--ui-host <host>	Host to serve UI on; specifying this option opens UI in a browser tab.
--ui-port <port>	Port to serve UI on, 0 for any free port; specifying this option opens UI in a browser tab.
-u or --update-snapshots [mode]	Update snapshots with actual results. Possible values are "all", "changed", "missing", and "none". Running tests without the flag defaults to "missing"; running tests with the flag but without a value defaults to "changed".
--update-source-method [mode]	Update snapshots with actual results. Possible values are "patch" (default), "3way" and "overwrite". "Patch" creates a unified diff file that can be used to update the source code later. "3way" generates merge conflict markers in source code. "Overwrite" overwrites the source code with the new snapshot values.
-j <workers> or --workers <workers>	Number of concurrent workers or percentage of logical CPU cores, use 1 to run in a single worker (default: 50%).
-x	Stop after the first failure.
