PHP 7.4 in the test-suite

[Nek-]

Would be nice isn't it? But I know, I know. It's complicated, because of PHPUnit 8.

But here is something interesting. I tried the following:

diff --git a/composer.json b/composer.json
index f6faa66..fa65403 100644
--- a/composer.json
+++ b/composer.json
@@ -9,8 +9,8 @@
         "evenement/evenement": "^3.0 || ^2.0 || ^1.0"
     },
     "require-dev": {
-        "phpunit/phpunit": "^6.4 || ^5.7 || ^4.8.35",
-        "clue/stream-filter": "~1.2"
+        "clue/stream-filter": "~1.2",
+        "symfony/phpunit-bridge": "^5.0"
     },
     "autoload": {
         "psr-4": {

And then that:

$ composer install
$ vendor/bin/simple-phpunit

# Here is the docker version if you prefer
$ docker run --rm -v $(pwd):/app -w /app composer:latest composer install
$ docker run --rm -v $(pwd):/app -w /app php:7.4 vendor/bin/simple-phpunit

And here is the output. Not bad for a code with no modification!

WARNINGS!
Tests: 176, Assertions: 259, Warnings: 14, Skipped: 33.
$ echo $?
0 # no test suite modification no error with PHP 7.4 ✨

I hope it helps. ✌️
