It can also optionally inline annotate the specific tests in the files during pull requests. **NOTE:** Tachycardia will only detect the slow tests in your test suites but will offer no explanation as to why these identified are slow. You should use a dedicated profiler for these instead. ``` $ vendor/bin/phpunit PHPUnit 10.5.5 by Sebastian Bergmann and contributors.

You can install using [Composer](https://getcomposer.org): ``` composer require --dev nexusphp/tachycardia ``` Configuration ------------- [](#configuration) Tachycardia supports these parameters: - **time-limit** - Time limit in seconds to be enforced for all tests. All tests exceeding this amount will be considered as slow. ***Default: 1.00*** - **report-count** - Number of slow tests to be displayed in the console report. This is ignored on Github Actions report. ***Default: 10*** - **precision** - Degree of precision of the decimals of the test's consumed time and allotted time limit. ***Default: 4*** - **format** - The format of the renderer for the console. - **ci-format** - The format of the renderer for the CI. Renderer formats for both the console and CI could be any of: FormatFor Console?For CI?Remarks**list**✅︎❌Default for console**table**✅︎❌**github**✅︎✅︎Default for CI**gitlab**✅︎✅︎**teamcity**✅︎✅︎To use the extension with its default configuration options, you can simply add the following into your `phpunit.xml.dist` or `phpunit.xml` file. ``` ``` Now, run `vendor/bin/phpunit`. If there are test cases where the time consumed exceeds the configured time limits, these will be displayed in the console after all tests have completed. If you wish to customize one or more of the available options, you can just change the entry in your `phpunit.xml.dist` or `phpunit.xml` file. ``` ``` Documentation ------------- [](#documentation) - [Reporting Slow Tests](docs/enable_reporting.md) - [Enable/disable console reporting using environment variable](docs/enable_reporting.md#enabledisable-console-reporting-using-environment-variable) - [Enable/disable profiling in Github Actions](docs/enable_reporting.md#enabledisable-profiling-in-github-actions) - [Custom Time Limits](docs/custom_time_limits.md) - [Setting custom time limits per test](docs/custom_time_limits.md#setting-custom-time-limits-per-test) - [Setting custom time limits per class](docs/custom_time_limits.md#setting-custom-time-limits-per-class) - [Disabling time limits per test or per class](docs/custom_time_limits.md#disabling-time-limits-per-test-or-per-class) - [Using Attributes instead](docs/custom_time_limits.md#using-attributes-instead) - [Tabulating results instead of plain render](docs/tabulating_results.md) - [Rerunning slow tests to see if these are fast now](docs/rerunning_tests.md) Upgrading --------- [](#upgrading) Upgrading from v1.x to v2.x?

Inspiration ----------- [](#inspiration) Tachycardia was inspired from [`johnkary/phpunit-speedtrap`](https://github.com/johnkary/phpunit-speedtrap), but injected with anabolic steroids. Tachycardia is actually a [medical term](https://www.webmd.com/heart-disease/atrial-fibrillation/what-are-the-types-of-tachycardia)referring to a heart rate that exceeds the normal resting rate in general of over 100 beats per minute.
