PHPUnit tests in Lumen won't connect to local mysql database



I have a lumen app that can query a local mysql database with no problems. However, when I try to run PHPUnit tests it fails to connect to my local database, but it will connect to an external one without any problems. I get the following error:


IlluminateDatabaseQueryException: SQLSTATE[HY000] [2002] No such file or directory

Caused by
PDOException: SQLSTATE[HY000] [2002] No such file or directory



Once again, I have absolutely no problem querying my local database through the regular routes of my app. It will connect to an external database in PHPUnit tests, but fails to connect to the local databasel



In my .env file I have the following


######## LOCAL DATABASE ########
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=name_of_my_db
DB_USERNAME=my_username
DB_PASSWORD=my_password

######## External DATABASE ########
# DB_CONNECTION=mysql
# DB_HOST=host_of_external_server
# DB_PORT=3306
# DB_DATABASE=name_of_my_db
# DB_USERNAME=my_username
# DB_PASSWORD=my_password



I can uncomment the external connection and it works 100% of the time. I also tried using 127.0.0.1 as the DB_HOST field but it still fails, but with the following error.


PDOException: SQLSTATE[HY000] [2002] Connection refused



I have not touched my phpunit.xml file and I've cleared my cache more times than I can count.





The lumen app can connect either to remote or local. But UnitTest can only connect to remote. Please confirm.

The difference between local and remote access is that mySQL uses a socket file instead of TCP/IP for local connections, so there may be a small config issue.

@bcperth yes, that's correct. Lumen app can connect to either remote or local, but PHPUnit can only connect to remote. I'm going to attempt one of these solutions, but I'd still like to know why PHPUnit can't use the standard connections in Lumen stackoverflow.com/questions/25495364/…

@bcperth I was able to get the mysql connection to work using this laravel package packagist.org/packages/stechstudio/laravel-ssh-tunnel . If you post your suggestion as an answer I'll mark it as correct and follow up to it with some details that might help others in the future. Thanks!

Not sure how I helped exactly except to trigger a few neuron connections somehow - but thanks!

You have confirmed that the Lumen app can connect to remote or local, but UnitTest can only connect to remote.



The difference between local and remote access is that mySQL uses a socket file instead of TCP/IP for local connections, so there may be a small config issue.



I understand you have now solved it using the laravel ssh tunnel package below.

As per your suggestion it would be great if you add some implementation/config details here for others readers :-)

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
