Clock
=====

[](#clock)

A simple interface to get the current time without binding to global system resources, plus configurable implementations that you can use in your unit tests.

Clock Usage
-----------

[](#clock-usage)

```
function yourCode(Clock $clock) {
    $time = $clock->now(); // Returns DateTimeImmutable. More testable than initializing a new instance
}
```

Clock interface:

```
interface Clock {
    public function now(): \DateTimeImmutable;
}
```

Provided implementations:

- `SystemClock`: Uses global system resources
- `StubClock`: Returns value provided in the constructor. Useful in tests
- `CollectionClock`: Returns specified values sequentially. Useful in tests
- `IncrementingClock`: Returns an incremented starting time infinitely. Useful in tests

Installation
------------

[](#installation)

To use the Clock library in your project, add a dependency on wmde/clock to your project's `composer.json` file. Here is a minimal example of a `composer.json`file that just defines a dependency on Clock 1.x:

```
{
    "require": {
        "wmde/clock": "~1.0"
    }
}
```

Development
-----------

[](#development)

For development you need to have Docker and the `docker compose` plugin installed. Local PHP and Composer are not needed.

### Installing the development dependencies

[](#installing-the-development-dependencies)

To pull in the project dependencies (PHPUnit, PHPStan, etc.) via Composer, run:

```
make install-php

```

To update the dependencies, run

```
make update-php

```

### Running the CI checks

[](#running-the-ci-checks)

To run all CI checks, which includes PHPUnit tests, PHPCS style checks and coverage tag validation, run:

```
make

```

### Running the tests

[](#running-the-tests)

To run only the PHPUnit tests run

```
make test

```

To run only a subset of PHPUnit tests or otherwise pass flags to PHPUnit, run

```
docker-compose run --rm app ./vendor/bin/phpunit --filter SomeClassNameOrFilter

```
