Allow for application testing using SQLite

[mralston]

Issue #177

Laravel Pulse doesn't support SQLite.

It is common to use SQLite whilst running tests of an application built using Laravel.

Pulse's migration throws an error if the database driver is SQLite, causing application tests to fail.

This pull request adds an App::environment('testing') check which allows SQLite during testing. Running the migration in any other environment will throw the original exception.

Here is the modified code:

match ($driver = $connection->getDriverName()) {
    'mysql' => $table->char('key_hash', 16)->charset('binary')->virtualAs('unhex(md5(`key`))'),
    'pgsql' => $table->uuid('key_hash')->storedAs('md5("key")::uuid'),
    'sqlite' => App::environment('testing') ? $table->char('key_hash', 16) : throw new RuntimeException("Unsupported database driver [{$driver}]."),
    default => throw new RuntimeException("Unsupported database driver [{$driver}]."),
};

Just disable Pulse during tests with PULSE_ENABLED?

Thanks for the PR!

I'm not opposed to adding SQLite support so Pulse works locally, but I'd want to see it fully implemented (i.e. SQLite-specific expressions for the upsert* methods) along with CI tests.

Agree with @driesvints solution if you just want to disable Pulse locally.
