How to solve the problem of inefficiency in PHP unit testing? Use spatie/phpunit-watcher to do it!

You can learn composer through the following address:

During the development process, frequent manual unit tests are not only time-consuming, but also easy to miss important modified tests. Recently, I encountered this problem in my project, which led to a significant reduction in development efficiency. After some exploration, I found the spatie/phpunit-watcher tool, which can automatically detect code changes and rerun PHPUnit tests, greatly improving my development efficiency.

Install spatie/phpunit-watcher

Installing this tool using Composer is very easy. You can choose to install globally for use in any project:

 <code class="bash">composer global require spatie/phpunit-watcher</code>

Alternatively, you can install it in your project as a development dependency:

 <code class="bash">composer require spatie/phpunit-watcher --dev</code>

Using spatie/phpunit-watcher

After installation, you can start the monitor using the following command:

 <code class="bash">phpunit-watcher watch</code>

This command will automatically run the test and rerun the test if the file in src or tests directory changes. If you need to pass parameters to PHPUnit, you can do this:

 <code class="bash">phpunit-watcher watch --filter=it_can_run_a_single_test</code>

Custom configuration

You can customize the behavior of the tool by creating a configuration file called .phpunit-watcher.yml . For example, you can specify the monitored directory, exclude certain directories, set notification options, etc.:

 <code class="yaml">watch: directories: - src - tests exclude: - lib fileMask: '*.php' notifications: passingTests: false failingTests: false phpunit: binaryPath: vendor/bin/phpunit arguments: '--stop-on-failure' timeout: 180</code>

Practical application effect

Since I started using spatie/phpunit-watcher, my development process has become smoother. After each code modification, the test runs automatically, ensuring my code is always in a reliable state. This not only saves time, but also reduces the cumbersomeness of manually running tests, greatly improving development efficiency.

Summarize

spatie/phpunit-watcher is a very practical tool, especially suitable for developers who need to run unit tests frequently. It helps developers discover and fix problems faster by automating the testing process, thereby improving overall development efficiency. If you encounter similar problems, you might as well try this tool, and I believe you will find its power.
