# FIG - Log Test
Testing utilities for the [`psr/log`][] package that backs the [PSR-3][] specification.
* `Psr\Log\Test\LoggerInterfaceTest` provides a base test class for ensuring compliance with the LoggerInterface.
* `Psr\Log\Test\TestLogger` is a mock class for testing purposes.
## Installation
This package should be used only for tests.
For PHP 8.0+ only, you may remove support for `psr/log: 1.x`:
```json
{
"require": {
"php": ">=8.0.0",
"psr/log": "^2.0 | ^3.0"
},
"require-dev": {
"fig/log-test": "^1.1"
}
}
```
If the project supports older versions of PHP:
```json
{
"require": {
"psr/log": "^1.1.14 | ^2.0"
},
"require-dev": {
"fig/log-test": "^1.0"
}
}
```
> **Note:** In `psr/log: 3.0.0`, `Psr\Log\LoggerInterface` has union types for method arguments.
> Implementing this interface with PHP 7 compatibility is not possible.
## Versions
The version of `fig/log-test` that is installed after composer dependencies resolution varies with the version of `psr/log`.
| psr/log | fig/log-test | |
|---------------|--------------|-------------------------------------------------|
| `^1.1.14` | `1.0.*` | Empty package, classes a provided by `psr/log`. |
| `^2.0\|^3.0` | `^1.1` | Imports test classes removed from `psr/log`. |
